Basic Care Guide

Cultivation:WaterDetail

Water

Hedge cactus is a drought-tolerant plant that does not require frequent watering. Water thoroughly when the soil is completely dry. When potted, water slowly, wait for water to flow out the bottom, and then pour the excess water from the tray to avoid water accumulation.
Spring, summer, and fall are its growing seasons. Water once or twice a week to keep the soil slightly wet. In winter, water less; just keep the soil from drying excessively; usually once a week. Besides, water with rainwater or distilled water rather than tap water.
Tap water contains a lot of calcium, magnesium, and other mineral salts. Long-term use tends to cause soil compaction. Avoid splashing water on its stem when watering to prevent rotting.

Water

Hedge cactus is native to regions with arid temperatures, and it's important not to overwater them. This plant needs moderate moisture levels and minimal care, so it's important to know how to water it properly.
Potted Hedge cactus
Hedge cactus is very tolerant of drought. This means that you don't need to water them very often. Watering frequency should also depend on the climate where you live. Most of the time, you only need to water your succulents once every two to three weeks in the summer and spring. Another tip when watering this species is to water it from the bottom. This is for the proper absorption of water to the roots, enabling it to circulate the nutrients from the soil towards its whole body. When you accidentally spill water at the top part, this can cause the development of diseases and fungi. During the winter and fall, reduce the watering or avoid this as this plant tends to become dormant. You can cut back on watering or once every 21 to 28 days when it begins to cool down.
In humid locations, there's no need to water a lot. When keeping the Hedge cactus indoors, you won't have to keep the moisture high, especially if the plant does not receive too much sunlight. When there's too much moisture and not enough light, this can spell disaster for the succulents.
Before you give this plant a drink, it's always a good idea to check the soil's moisture levels by poking your finger in it or using a moisture meter. This will tell you whether the soil is already too dry or if there's still moisture. It's a technique used by owners of smaller potted plants to know whether it's time to water or not.When they are fully grown, water them less since they can survive without water compared to when they were small. You need to give them time to get used to your climate and growing conditions before watering them. If they are indoors, keep them in indirect light and water them less frequently. Avoid using cold water during the winter and months, and you might be overwatering when the plants are located indoors.
Ground Hedge cactus
Know that these plants can survive for weeks without any water. This is because they have water storage capacity that can conserve water for a long time. so it will conserve enough water to stay alive even if they are in the wild.
When they are planted outdoors, never water them lightly as this will result in more shallow root growth. Wait for a few weeks and only give them a drink when the soil around them is too dry. rainwater can be another excellent alternative when you want to hold back on watering. When you live in an area where you don't get much rain, water at least once every three weeks to prevent the soil from drying too much.
Underwater and overwater
When you're still in the process of buying a Hedge cactus , make sure to ask first if the soil is properly draining or sandy. When the topsoil does not properly drain, there's a chance that the plant will likely not receive enough water in the future.
When you see that the Hedge cactus begins to turn yellow, know that this can be caused by underwatering or overwatering. Also, the browning and dropping symptoms indicate that your plant is getting too much moisture and water. If there's not enough water, the indication can be seen with the yellow tips that can begin to form on stems and branches.
When the soil is too wet, then there might be the presence of fungal infections. You should allow everything to dry, and you should not overwater.You can see the squishy stems, drooping growth, and discolored parts that are all signs of too much moisture. It's critical to give the species time to recover and allow the pot to dry. Transfer it to a different container to avoid root rot and prevent it from dripping. If planted outside, you can also transfer it into a pot, especially in the winter, to help it recover.
Another thing is that the Hedge cactus tends to die when it's constantly getting overwatered and if it's receiving too much rain if planted outside. Use rainwater or distilled water whenever possible as the plants don't like many minerals in their drink.

What's the best method to water my Hedge cactus?
Another tip when watering this species is to water it from the bottom. This is for the proper absorption of water to the roots, enabling it to circulate the nutrients from the soil towards its whole body. When you accidentally spill water at the top part, this can cause the development of diseases and fungi.
Use sprinklers when you have irrigation systems. Get the small sprinklers if you have Hedge cactused in your garden. It's best to get the revolving ones that allow you to change the water delivery patterns whenever you need them. Avoid turning on the sprinkler on windy days. Make sure to use the soak and dry method regardless if the Hedge cactus is in a pot or your garden. This will evenly distribute the moisture across the root systems resulting in healthier growth.
Some owners might want to get a built-in drainage system for their succulents. This is where layers of porous materials like recycled glass or hydro stones are placed beneath the soil. They will generally be a reservoir for excess water, so it's important not to pour too much water into these built-in systems.

How much water does my Hedge cactus need?
Water this succulent efficiently and make sure to cover the entire pot. Set a saucer at the bottom of the pot so the roots will get enough moisture. When you see that the soil begins to saturate, take out the saucer immediately. The holes in the pot and the amount of soil will determine the frequency and the quantity of water you should give your plant. A can of water is often more than enough for the Hedge cactus especially if they are planted in pots.
When you plant them in the garden or outdoors, you need to include the rainwater they receive. About an inch of rainwater is more than enough to last them for a few weeks, so refrain from watering. When they are outside, you need to water them in the morning with about a gallon of water after you see that the soil is bone dry so the sunlight can help evaporate the excess moisture.

Why is watering my Hedge cactus important?
Watering the Hedge cactus will help transport the nutrients that it needs from the soil to the rest of the plant. Without enough moisture, the Hedge cactus won't remain healthy or might even become malnourished. Watering should be done when you see some signs that the plant is thirsty. When you're in doubt, you should never overwater as this can be a way to kill them.
The best way to water them is the soak and dry method. When you see that the soil becomes too dry, you should soak them in water until you see that the pot is dripping with water underneath. Then, go for weeks without watering to give the soil a chance to rest.

How can I ensure that i'm watering my Hedge cactus adequately?
Before you give this plant a drink, it's always a good idea to check the soil's moisture levels by poking your finger in it or using a moisture meter. This will tell you whether the soil is already too dry or if there's still moisture. It's a technique used by owners of smaller potted plants to know whether it's time to water or not.
Assess the needs of your Hedge cactus and know that it requires watering every two weeks during the summer. You can go as far as three weeks in the hot season before watering this, but in the fall or winter, there should not be any water at all. Allow the soil to dry between irrigations. They can be grown in greenhouses and other warm spots indoors and thrive well. When your plant is getting too much light, you can increase the watering frequency as long as you see that the soil is dry. They can also be grown outdoors, where you will need to water them less. Give it enough water once every three weeks; this should be more than enough. Don't rely alone on irrigations and sprinklers to reach their bases. Use a soaker hose that will hit the ground and spread the water. Make sure it won't hit much of the body of the plant as this can result in diseases.

Should I adjust the frequency of watering my Hedge cactus according to different seasons or climates?
Hedge cactus is very tolerant of drought. This means that you don't need to water them very often. Watering frequency should also depend on the climate where you live. In a dry environment, you can make the watering conditions adapt well to your plants' needs. When they are in their early flowering stages, you might want to increase watering to help them grow. When they are receiving enough sunlight, water only in the morning. Specifically, they can be watered once every 10 to 14 days during the summer. You can increase this frequency during times of heat waves and make sure to mist the base from time to time lightly. When it's too cold, you can cut back on watering or once every 21 to 28 days when it begins to cool down.

Should I adjust the watering frequency during the different growing stages of my Hedge cactus?
When you've just repotted the plant, you should wait for a week before you can water your Hedge cactus. When it's time to water them, be generous until you see the water coming out of the potholes but don't make it a deluge. When they have already grown and received medium light, you might want to water them once every 2 to 3 weeks since they are very tolerant to drought.
In the winter, you will further need to cut back on watering. The ideal time is to water it once every 3 to 4 weeks as long as the soil does not feel too dry. Winter is their resting season, so they don't consume a lot of energy or grow at this time.
If you grow the plants outdoors, rainwater can be another excellent alternative when you want to hold back on watering. When you live in an area where you don't get much rain, water at least once every three weeks to prevent the soil from drying too much.
In humid locations, there's no need to water a lot. When keeping the Hedge cactus indoors, you won't have to keep the moisture high, especially if the plant does not receive too much sunlight. When there's too much moisture and not enough light, this can spell disaster for the succulents.

What should I be careful with when I water my Hedge cactus in different seasons, climates, or during different growing periods?
The Hedge cactus growing outdoors can thrive with rainfall, but when it’s planted in a pot, you need to be careful while Hedge cactus is still in the growing stage. One way to prevent overwatering is to check the top bottom inches of the soil for moisture. Once again, you need it to be dry so you can water it again. If you're unsure of the amount and the frequency, especially during the growing phase, go with underwatering and slightly increase it when you see a need. It's always a good idea to take a picture of the Hedge cactus and note how it looks after watering it. You can take things further by using moisture meters or hygrometers to check the air and soil moisture. These tools are available from various shops and can be valuable when you want to know the readings for humidity and water.

Should I water my Hedge cactus differently when I plant it indoors vs outdoors?
Know that these plants can survive for weeks without any water. This is because they have water storage capacity that can conserve water for a long time. so it will conserve enough water to stay alive even if they are in the wild.
When they are fully grown, water them less since they can survive without water compared to when they were small.

Avoid using cold water during the winter and months, and you might be overwatering when the plants are located indoors. Give this a rest, especially during the winter and fall.
When they are outdoors, refrain from watering too much. They should be able to get enough humidity, moisture, and rainfall that will keep them alive. Only water when you see that their leaves are becoming droopy and yellowish. Always lean on the side of underwatering as the Hedge cactus is very tolerant to dry conditions. They don't like wet feet and might wilt when you water them too much.

Cultivation:FertilizerDetail

Fertilizer

In growing seasons (namely spring, summer and fall), fertilize hedge cactus once a month with liquid fertilizer. No fertilizer is required in winter. A small amount of slow-release fertilizer can be well mixed into the soil when repotting in spring or fall.
Use nitrogen fertilizer during seedling and phosphate-potassium fertilizer before and after blooming. The fertilizer concentration should be as low as possible. It would be better to apply low-concentrate fertilizer several times rather than to use a high concentration. If the base is yellow and grows slowly, the cause may be excessive fertilizer, and fertilization should be immediately stopped.

Fertilizer

Often found growing in rock gardens and used in xeriscaping, Hedge cactus adds plenty of interest and texture to the area. It is a slow-growing plant, and this affects its care. Hedge cactus does not require a lot of nutrients to thrive. Knowing when and how to feed your specimen will help ensure you get years of enjoyment from your plant. Fertilizing Hedge cactus adds nutrients to the growing medium. Even though it does store water and nutrients, applying plant food during the growing season helps support healthy growth. Fertilizing can also encourage mature specimens to produce blooms in the growing season.
While all plants benefit from additional nutrients, Hedge cactus only needs a light dose of fertilizer during the growing season. The frequency of fertilization should be 1-2 times a year. It is suggested to fertilize your Hedge cactus in the spring and autumn, but not in winter&summer when it is dormant. Be careful with repotted plants, you will want to reduce the amount of fertilizer. It’s also a good idea to wait a couple of months after repotting before you start applying fertilizer. It’s best to use a liquid plant food formulated for succulents and cacti when you are fertilizing Hedge cactus. Dilute the fertilizer with water to half-strength. You do not want the fertilizer building up in the soil. Apply the fertilizer to the base of the plant and water thoroughly, ensuring any excess moisture drains from the container or seeps into the ground.
It is easier to use liquid plant food when you are fertilizing Hedge cactus, but granules are another option. Follow the directions on the packaging, making sure you dilute liquid fertilizers to half-strength. Whether you are using granules are liquid plant food, always apply it to the soil. Cover the granules with a thin layer of soil and water regardless of the type of plant food you are using.
Over-fertilizing Hedge cactus is a common problem with new and experienced gardeners. The plant has low nutritional needs and it’s easy to apply a little too much fertilizer. Over-fertilizing Hedge cactus can burn the plant’s sensitive roots resulting in its slow decay. Without its root system, the plant cannot absorb nutrients and moisture.
Like most plants, Hedge cactus has a dormancy period and it is when you want to stop the applications of fertilizer. In the summer and winter, the plant ceases growing, and it is when you want to stop applying fertilizer. It’s also a good idea to cease fertilizing for the first couple of months after repotting in the spring.

Cultivation:SunlightDetail

Sunlight

Hedge cactus is a heliophilic plant and needs sufficient sunlight for its growth and blooming. It can be placed on the outdoor balcony or in the garden without shade. However, long-time exposure to blazing sunlight should be avoided in hot summer, when it needs to be shaded or cooled a little to prevent high temperatures from damaging it.

How much sunlight does Hedge cactus need to grow?
Hedge cactus should get at least 6 hours of sun per day, and preferably more. An actual minimum number of hours can vary depending on the intensity of sunlight and other environmental factors, but it is unlikely that the Hedge cactus will get too much sunlight. They do fine with up to 14 hours of sun per day.

Should I protect Hedge cactus from sun exposure?
Hedge cactus usually grows in some of the hottest, sunniest places in the world and is well adapted to that kind of environment, so it does not need to be protected from the sun. However, you should be careful about making a sudden move into a very sunny location if your Hedge cactus is not used to it. Plants need time to adapt to different conditions, so start by moving this plant into the sun for a couple of hours at a time each day, then gradually lengthen the amount of sun exposure. Once adapted, most types of Hedge cactus will be fine in full sun and don't need protection.

What will happen if Hedge cactus doesn't get enough sunlight?
Without enough sunlight, Hedge cactus will fail to thrive and grow. Common symptoms of inadequate sunlight include pale coloring, wilting leaves, and leaf drop. Hedge cactus may also exhibit etiolation (also called legginess). This condition occurs as the plant attempts to stretch toward the light source, leading to a sparse appearance and weak stems.

What will happen if Hedge cactus gets too much sunlight?
Hedge cactus may develop shades of red, pink, or orange as a means of protection from excess sunlight, so many people like to cause mild sun stress to these plants during the summer. This is not harmful, and they will revert to their normal coloring when light levels decrease from autumn to spring.
If moved too quickly into direct sun, Hedge cactus can suffer from sunburn. This looks like white or brown spots on the uppermost leaves that have been exposed to the most sun. A sunburned plant should be moved to a shadier location and watered if needed. Sun-damaged leaves can be removed, and should be replaced by new growth over time.

Does Hedge cactus need special care about sunlight during its different growth stages?
As with most plants, younger Hedge cactus will be more sensitive to strong sunlight and heat than a mature specimen. They should also be protected from direct sun immediately after being transplanted, either by a shade or by keeping the container in a shadier location until the plant is established and putting out new growth.

Are there any cautions or tips for sunlight and Hedge cactus?
It is best to water Hedge cactus in the morning, particularly during the summer months. If water sits on the leaves or in the crown of the plant, it can burn the plant when the water heats up. It’s also best not to water in the evening, since cooler overnight temperatures slow evaporation and fungi or bacteria can develop in the moist conditions.
Hedge cactus grown in pots should be rotated occasionally to keep them growing symmetrically. Plants will normally grow toward the light source, so they can develop much more quickly on one side than the other if they are not rotated.
If Hedge cactus is allowed to get dusty, it will not be able to access sunlight to create energy. The dust acts as a barrier, so the plant may show signs of inadequate light even if it’s in a sunny location. Keep the leaves and stems clean by wiping them periodically with a damp cloth to avoid this issue.

Cultivation:SoilDetail

Soil

Hedge cactus grows best in fertile, gravel-rich, water-permeable soil with a pH value of 6-7. The culture soil formula often used is 60% vermiculite + 20% coco coir or peat moss + 20% sandy soil. A small amount of organic potting soil can also be added. Lightweight culture media such as vermiculite can be added to improve the air permeability of the soil. Eggshell powder or vermicompost can also be added to increase the soil fertility.
Roots of hedge cactus are very sensitive to oxygen deficiency. If the soil is poorly permeable to air and water, root rot can set in. It's easy to judge permeability: when watering, water should pass through the medium quickly, rather than stop at the soil surface and slowly seep down. Repot and loosen the soil every year to ensure the air permeability of the soil.

Cultivation:HarvestDetail

Harvest

In addition to the seeding mentioned above, main propagation methods include division and grafting. To divide, cut off the tip or lateral branches of the stem with a knife and plant it in soil. After a period of time, many small shoots will grow up near the cut. When a shoot grows to proper size, it can be cut off and transplanted to form a new plant.
To graft, select a suitable rootstock. Cut the tip of the rootstock, such as the stem of pitahaya (Hylocereus undatus), and then put hedge cactus, with its roots removed, in the center of the rootstock and fix it with a rope. After 1-2 weeks, the two parts grow together and the rope can be removed.

Propagation

If you want to get more plants, you can propagate them as follows.
The active growing season during the spring and summer is the best time to propagate Hedge cactus. During this period, the plants are generating a lot of energy for new growth and should have plenty of stems that can be used for propagation. They can also recover from having cuttings taken during this season than during the slower autumn and winter seasons.
The following are what you need to prepare before propagation can take place.
  1. Sharp scissors or knife
  2. Diluted bleach solution or isopropyl alcohol to clean tools
  3. Pot(s) or nursery tray with drainage holes
  4. Special soil for succulents
  5. Clear plastic bag or a humidity dome for covering cuttings
  6. Rooting hormone (optional but recommended)
  7. Gardening gloves
Steps:
Step 1: Prepare containers by filling them with moistened planting material leaving about half an inch of space from the top of the container.
Step 2: Choose healthy parts for propagation. Cut off healthy stem nodes; the nodes should not be new growth, as this is not easy to succeed. You need to use a clean knife to break or cut off the stem intact at the node location.
Step 3: Leave them for 1-2 weeks, as you need to wait for the cut wounds to dry before taking cuttings. Dip the bottom end of the cutting into rooting powder (if using) according to the directions.
Step 4: Insert the stems into a loose, airy substrate, keeping them tilted, each about one-third of the way into the substrate. Water thoroughly once after planting, after which you need to wait until the soil is dry 2 inches under the surface before watering again.
Step 5: Place it in a location where the cuttings can get light but no direct sunlight, as this can be too intense for cuttings. Water occasionally and do not let the Hedge cactus dry out.
Most species will begin to produce roots in about 3 weeks, After rooting, the plant will gradually grow new leaves, at which time you can start to harden off the Hedge cactus. Hardening off involves gradually exposing the Hedge cactus to more sunlight so that they have time to adjust before being moved permanently outside. Hardening off should usually take about 1 to 2 weeks depending on the outdoor conditions and the type of Hedge cactus. After this period, Hedge cactus can be planted in containers or directly in the ground.

Cultivation:PropagationDetail
Sow, plant, or repot in spring or fall when the temperature is 15 to 20 ℃ . Keep air humidity high when seeding. Use plastic film to cover the soil and remove it after the seeds germinate.
Use permeable clay flowerpots for potted plants. Too large a flowerpot accumulates water easily, while too small a flowerpot limits the development of roots. Before planting, expose soil to blazing sunlight and disinfect to kill pathogens.
If planted in the garden, hedge cactus prefers an area with full sun and loose soil. Remove all weeds and replace the soil if needed to ensure good water permeability and avoid root rot. Wear gloves or use tongs when planting to prevent your fingers from getting pricked. You can also wrap the plant in a towel to help you move it.
Cultivation:PlantingDetail
Most fruits of hedge cactus are edible. Pick the fruit when they turn red. Avoid food safety issues by confirming the species with experts. Wear gloves or use scissors and other tools to harvest.

Common Pests & Diseases

Common issues for Hedge cactus based on 10 million real cases
Brown spot
Brown spot Brown spot
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Plant dried up
Plant dried up Plant dried up
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Low light
Low light Low light
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Solutions: Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed. Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn. Introduce appropriate artificial lighting. Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.
Stem rot
Stem rot Stem rot
Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Solutions: If the plant is only infected a little, it can sometimes be saved. This mainly applies to houseplants that are grown in pots. Here's what to do. Remove the plant from the pot and gently shake off as much soil as possible. Using pruning tools that have been disinfected, remove any diseased foliage and roots. Be sure the new pot has good drainage holes and wash it with one part bleach and nine parts water to ensure that it is completely clean and sanitized. Dip the plant's roots in fungicide to kill off any remaining fungal spores before potting into the clean growing medium. Only water the plant when the top inch of the soil is dry and never let the plant sit in water. For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.
  2. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread.
  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.

Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Low light
plant poor
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Overview
Overview
All plants require light, and if they do not receive it in the quantities that they require this distorts their growth in a process known as etiolation. In essence, etiolated plants are diverting all of their energy to growing taller in a desperate attempt to reach a position where they can meet their light requirements. Many other growth factors are harmed by this, and so light-deprived plants can become weak and distorted until they are almost unrecognizable. Low light symptoms are most commonly seen in houseplants, but outdoor specimens can also be affected.
Symptom Analysis
Symptom Analysis
Although symptoms will vary in different plants, the general symptoms of low light are easy to spot.
  1. Plant stems grow tall and lanky.
  2. There are less leaves, and both leaves and stems tend to be pale and insipid looking. This is due to a shortage of chlorophyll.
  3. All plant parts become weakened and may droop, as energy is diverted toward too-fast growth as the plant stretches itself toward any source of light.
Disease Cause
Disease Cause
Plants need sunlight in varying amounts for photosynthesis – a process that produces energy for growth and fruit and flower production. Low light causes a plant to divert all energy to upward (apical) growth in order to find better light. Plant hormones called auxins are transported from the actively-growing tip of the plant downwards, to suppress lateral growth. A drop in cellular pH triggers expansins, nonenzymatic cell wall proteins, to loosen cell walls and allow them to elongate. This elongation results in the abnormal lengthening of stems, especially internodes, or plant "legginess" which is observed in etoliated plants.
Solutions
Solutions
Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed.
  • Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn.
  • Introduce appropriate artificial lighting.
  • Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.
Prevention
Prevention
To avoid etiolation, provide an adequate amount of light from the beginning.
  1. Choose a location that matches each plant's ideal light needs. Many indoor plants do best in or near a south-facing window, which will provide the longest hours of sunlight. Flowering plants and those with colored leaves typically need more light than purely-green plants, as photosynthesis occurs in the green portions of leaves.
  2. Select plants with light needs that match a location's conditions. Some cultivars and varieties require less light than others.
  3. Use a grow light. Darker locations may require artificial illumination. A grow light may also become more necessary during winter, when sunlit hours are at their shortest.

Stem rot
plant poor
Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Overview
Overview
Stem rot is a serious disease and can affect many different types of plants. it can be particularly prevalent when the temperature of the soil is over 16 ℃ and there's a lot of moisture in the soil. This could be from unusually heavy rainfalls or too much irrigation. Once stem rot sets in, it's very difficult to get rid of the disease and most affected plants will have to be discarded. This is especially the case for vegetables, herbs, and other herbaceous plants that have soft stems. This is why it's important to ensure that the soil used for growing these plants is well-drained and that overwatering is avoided. Using good cultural practices also help in curbing these types of fungal diseases.
Symptom Analysis
Symptom Analysis
Plants that have been affected by stem rot will first display a yellowing of the lower leaves. This is followed by obvious wilting and stunted growth.
If the stem of the affected plant is examined closely, there will be some dark discolorations starting near the base and moving upward. If the roots of affected plants are examined, they will appear dark and mushy instead of white and healthy-looking. Eventually, the entire plant will wilt and die.
Disease Cause
Disease Cause
Stem rot is caused by a variety of soil-borne fungus pathogens. The type of fungus depends on the species of plant that is affected. Two fungi responsible for stem rot are Rhizoctonia and Fusarium. These fungal pathogens live in soil and migrate to the plant when conditions are optimum. This includes warm, humid weather and excessive soil moisture. Commonly, vegetable seedlings are affected by these fungi.
Sclerotinia sclerotiorum is another fungus that causes stem rot in plants. This fungus has a host range of over 350 different species of plants. Plants most susceptible to this fungus include many vegetable varieties such as cucumbers, beans, cilantro, carrots, cabbage, melons, lettuce, peas, onions, tomatoes, pumpkins, and squash. This fungus can produce different symptoms in different species. In some cases, the fungus causes irregular spots on stems and other plant material that appear water-soaked. On other plant species, the fungus appears as dry lesions that grow and girdle the stem of the plant.
The third type of fungus that causes stem rot is Phytophthora capsici. Plants that belong to the cucumber family are most susceptible to this fungal infection. This fungus manifests as water-soaked lesions on the stems that then turn brown and girdle the stem.
All of these fungal pathogens are transmitted to the plant by water splashing from the soil up onto the plant. That's because the fungal spores live in the soil where they wait for the right conditions to infect the plants.
Solutions
Solutions
If the plant is only infected a little, it can sometimes be saved. This mainly applies to houseplants that are grown in pots. Here's what to do.
  1. Remove the plant from the pot and gently shake off as much soil as possible.
  2. Using pruning tools that have been disinfected, remove any diseased foliage and roots.
  3. Be sure the new pot has good drainage holes and wash it with one part bleach and nine parts water to ensure that it is completely clean and sanitized.
  4. Dip the plant's roots in fungicide to kill off any remaining fungal spores before potting into the clean growing medium.
  5. Only water the plant when the top inch of the soil is dry and never let the plant sit in water.
For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.
Prevention
Prevention
For outdoor gardens:
  1. Raking the garden thoroughly in the springtime will help to cut down on pathogens that may be living in the soil.
  2. Using a copper fungicide on plants in the springtime will cut down on fungal growth and prevent the spread of infection.
  3. Placing a heavy layer of mulch on top of the soil will also prevent pathogens from splashing up onto the stems of plants.
  4. Place plants at the recommended spacing to encourage better air flow between them.
  5. Water plants at the base instead of overhead to prevent excessive moisture on foliage.
For indoor plants:
  1. Avoid overwatering houseplants and ensure the roots do not sit in water.
  2. Make sure that indoor plants receive adequate air circulation and light.

Common Problems

Why is its fleshy stem thinner and thinner as it grows?

more more
Thin stems may be caused by insufficient sunlight, insufficient water, or fertilizer deficiency. Move the pot to a brighter place, but avoid sunburn. Increase water and fertilizer.

How do I deal with root or stem rot?

more more
Excess water often leads to root and stem rot. Avoid accumulated water in soil. Prune rotten roots and stems and transplant to a new flowerpot in a well-ventilated place. The soil should be loose and air-permeable as far as possible.

Why doesn't my hedge cactus ever bloom?

more more
Firstly, it may not be time for the plant to bloom. Time from seedling to blooming can range between 2-20 years or longer. Secondly, the plant may need more sunlight, temperature or fertilizer. Increase the exposure to sunlight and fertilizer appropriately, supplement the fertilizer with phosphorus and potassium, or purchase special fertilizer for promoting blooming of hedge cactus.

Why does hedge cactus turn yellow?

more more
Hedge cactus turns yellow due to overwatering, insufficient sunlight, or pests. Hedge cactus does not require much water, and excess water leads to root anoxia and root rot. Generally, it does not need to be watered often. Water it only when the soil is completely dry. Remember to drain the water in the flowerpot tray. Sunlight can be increased, but avoid direct exposure to blazing sunlight to prevent sunburn. Remove a small amount of pests with alcohol. For large infestations, spray pesticide.

Basic Care Guide

Cultivation:WaterDetail

Water

Cultivation:WaterDetail
Hedge cactus is a drought-tolerant plant that does not require frequent watering. Water thoroughly when the soil is completely dry. When potted, water slowly, wait for water to flow out the bottom, and then pour the excess water from the tray to avoid water accumulation.
Spring, summer, and fall are its growing seasons. Water once or twice a week to keep the soil slightly wet. In winter, water less; just keep the soil from drying excessively; usually once a week. Besides, water with rainwater or distilled water rather than tap water.
Tap water contains a lot of calcium, magnesium, and other mineral salts. Long-term use tends to cause soil compaction. Avoid splashing water on its stem when watering to prevent rotting.
close

Water

Hedge cactus is native to regions with arid temperatures, and it's important not to overwater them. This plant needs moderate moisture levels and minimal care, so it's important to know how to water it properly.
Potted Hedge cactus
Hedge cactus is very tolerant of drought. This means that you don't need to water them very often. Watering frequency should also depend on the climate where you live. Most of the time, you only need to water your succulents once every two to three weeks in the summer and spring. Another tip when watering this species is to water it from the bottom. This is for the proper absorption of water to the roots, enabling it to circulate the nutrients from the soil towards its whole body. When you accidentally spill water at the top part, this can cause the development of diseases and fungi. During the winter and fall, reduce the watering or avoid this as this plant tends to become dormant. You can cut back on watering or once every 21 to 28 days when it begins to cool down.
In humid locations, there's no need to water a lot. When keeping the Hedge cactus indoors, you won't have to keep the moisture high, especially if the plant does not receive too much sunlight. When there's too much moisture and not enough light, this can spell disaster for the succulents.
Before you give this plant a drink, it's always a good idea to check the soil's moisture levels by poking your finger in it or using a moisture meter. This will tell you whether the soil is already too dry or if there's still moisture. It's a technique used by owners of smaller potted plants to know whether it's time to water or not.When they are fully grown, water them less since they can survive without water compared to when they were small. You need to give them time to get used to your climate and growing conditions before watering them. If they are indoors, keep them in indirect light and water them less frequently. Avoid using cold water during the winter and months, and you might be overwatering when the plants are located indoors.
Ground Hedge cactus
Know that these plants can survive for weeks without any water. This is because they have water storage capacity that can conserve water for a long time. so it will conserve enough water to stay alive even if they are in the wild.
When they are planted outdoors, never water them lightly as this will result in more shallow root growth. Wait for a few weeks and only give them a drink when the soil around them is too dry. rainwater can be another excellent alternative when you want to hold back on watering. When you live in an area where you don't get much rain, water at least once every three weeks to prevent the soil from drying too much.
Underwater and overwater
When you're still in the process of buying a Hedge cactus , make sure to ask first if the soil is properly draining or sandy. When the topsoil does not properly drain, there's a chance that the plant will likely not receive enough water in the future.
When you see that the Hedge cactus begins to turn yellow, know that this can be caused by underwatering or overwatering. Also, the browning and dropping symptoms indicate that your plant is getting too much moisture and water. If there's not enough water, the indication can be seen with the yellow tips that can begin to form on stems and branches.
When the soil is too wet, then there might be the presence of fungal infections. You should allow everything to dry, and you should not overwater.You can see the squishy stems, drooping growth, and discolored parts that are all signs of too much moisture. It's critical to give the species time to recover and allow the pot to dry. Transfer it to a different container to avoid root rot and prevent it from dripping. If planted outside, you can also transfer it into a pot, especially in the winter, to help it recover.
Another thing is that the Hedge cactus tends to die when it's constantly getting overwatered and if it's receiving too much rain if planted outside. Use rainwater or distilled water whenever possible as the plants don't like many minerals in their drink.

Cultivation:FertilizerDetail

Fertilizer

Cultivation:FertilizerDetail
In growing seasons (namely spring, summer and fall), fertilize hedge cactus once a month with liquid fertilizer. No fertilizer is required in winter. A small amount of slow-release fertilizer can be well mixed into the soil when repotting in spring or fall.
Use nitrogen fertilizer during seedling and phosphate-potassium fertilizer before and after blooming. The fertilizer concentration should be as low as possible. It would be better to apply low-concentrate fertilizer several times rather than to use a high concentration. If the base is yellow and grows slowly, the cause may be excessive fertilizer, and fertilization should be immediately stopped.

Fertilizer

Often found growing in rock gardens and used in xeriscaping, Hedge cactus adds plenty of interest and texture to the area. It is a slow-growing plant, and this affects its care. Hedge cactus does not require a lot of nutrients to thrive. Knowing when and how to feed your specimen will help ensure you get years of enjoyment from your plant. Fertilizing Hedge cactus adds nutrients to the growing medium. Even though it does store water and nutrients, applying plant food during the growing season helps support healthy growth. Fertilizing can also encourage mature specimens to produce blooms in the growing season.
While all plants benefit from additional nutrients, Hedge cactus only needs a light dose of fertilizer during the growing season. The frequency of fertilization should be 1-2 times a year. It is suggested to fertilize your Hedge cactus in the spring and autumn, but not in winter&summer when it is dormant. Be careful with repotted plants, you will want to reduce the amount of fertilizer. It’s also a good idea to wait a couple of months after repotting before you start applying fertilizer. It’s best to use a liquid plant food formulated for succulents and cacti when you are fertilizing Hedge cactus. Dilute the fertilizer with water to half-strength. You do not want the fertilizer building up in the soil. Apply the fertilizer to the base of the plant and water thoroughly, ensuring any excess moisture drains from the container or seeps into the ground.
It is easier to use liquid plant food when you are fertilizing Hedge cactus, but granules are another option. Follow the directions on the packaging, making sure you dilute liquid fertilizers to half-strength. Whether you are using granules are liquid plant food, always apply it to the soil. Cover the granules with a thin layer of soil and water regardless of the type of plant food you are using.
Over-fertilizing Hedge cactus is a common problem with new and experienced gardeners. The plant has low nutritional needs and it’s easy to apply a little too much fertilizer. Over-fertilizing Hedge cactus can burn the plant’s sensitive roots resulting in its slow decay. Without its root system, the plant cannot absorb nutrients and moisture.
Like most plants, Hedge cactus has a dormancy period and it is when you want to stop the applications of fertilizer. In the summer and winter, the plant ceases growing, and it is when you want to stop applying fertilizer. It’s also a good idea to cease fertilizing for the first couple of months after repotting in the spring.

Temperature

Cultivation:WaterAndHardinessDetail
Hedge cactus is distributed throughout tropical, subtropical, and semi-desert regions with scarce rainfall, intense sunlight, and hot temperatures. The optimum temperature for growth is 20 to 35 ℃. Lower than 10 ℃ or higher than 35 ℃, growth slows and dormancy begins. The air humidity should not be too high and the environment should be well-ventilated. Avoid high humidity and accumulated water.

Cultivation:SoilDetail

Soil

Cultivation:SoilDetail
Hedge cactus grows best in fertile, gravel-rich, water-permeable soil with a pH value of 6-7. The culture soil formula often used is 60% vermiculite + 20% coco coir or peat moss + 20% sandy soil. A small amount of organic potting soil can also be added. Lightweight culture media such as vermiculite can be added to improve the air permeability of the soil. Eggshell powder or vermicompost can also be added to increase the soil fertility.
Roots of hedge cactus are very sensitive to oxygen deficiency. If the soil is poorly permeable to air and water, root rot can set in. It's easy to judge permeability: when watering, water should pass through the medium quickly, rather than stop at the soil surface and slowly seep down. Repot and loosen the soil every year to ensure the air permeability of the soil.

Harvest

Cultivation:PropagationDetail
In addition to the seeding mentioned above, main propagation methods include division and grafting. To divide, cut off the tip or lateral branches of the stem with a knife and plant it in soil. After a period of time, many small shoots will grow up near the cut. When a shoot grows to proper size, it can be cut off and transplanted to form a new plant.
To graft, select a suitable rootstock. Cut the tip of the rootstock, such as the stem of pitahaya (Hylocereus undatus), and then put hedge cactus, with its roots removed, in the center of the rootstock and fix it with a rope. After 1-2 weeks, the two parts grow together and the rope can be removed.

Propagation

If you want to get more plants, you can propagate them as follows.
The active growing season during the spring and summer is the best time to propagate Hedge cactus. During this period, the plants are generating a lot of energy for new growth and should have plenty of stems that can be used for propagation. They can also recover from having cuttings taken during this season than during the slower autumn and winter seasons.
The following are what you need to prepare before propagation can take place.
  1. Sharp scissors or knife
  2. Diluted bleach solution or isopropyl alcohol to clean tools
  3. Pot(s) or nursery tray with drainage holes
  4. Special soil for succulents
  5. Clear plastic bag or a humidity dome for covering cuttings
  6. Rooting hormone (optional but recommended)
  7. Gardening gloves
Steps:
Step 1: Prepare containers by filling them with moistened planting material leaving about half an inch of space from the top of the container.
Step 2: Choose healthy parts for propagation. Cut off healthy stem nodes; the nodes should not be new growth, as this is not easy to succeed. You need to use a clean knife to break or cut off the stem intact at the node location.
Step 3: Leave them for 1-2 weeks, as you need to wait for the cut wounds to dry before taking cuttings. Dip the bottom end of the cutting into rooting powder (if using) according to the directions.
Step 4: Insert the stems into a loose, airy substrate, keeping them tilted, each about one-third of the way into the substrate. Water thoroughly once after planting, after which you need to wait until the soil is dry 2 inches under the surface before watering again.
Step 5: Place it in a location where the cuttings can get light but no direct sunlight, as this can be too intense for cuttings. Water occasionally and do not let the Hedge cactus dry out.
Most species will begin to produce roots in about 3 weeks, After rooting, the plant will gradually grow new leaves, at which time you can start to harden off the Hedge cactus. Hardening off involves gradually exposing the Hedge cactus to more sunlight so that they have time to adjust before being moved permanently outside. Hardening off should usually take about 1 to 2 weeks depending on the outdoor conditions and the type of Hedge cactus. After this period, Hedge cactus can be planted in containers or directly in the ground.

Cultivation:PlantingDetail
Sow, plant, or repot in spring or fall when the temperature is 15 to 20 ℃ . Keep air humidity high when seeding. Use plastic film to cover the soil and remove it after the seeds germinate.
Use permeable clay flowerpots for potted plants. Too large a flowerpot accumulates water easily, while too small a flowerpot limits the development of roots. Before planting, expose soil to blazing sunlight and disinfect to kill pathogens.
If planted in the garden, hedge cactus prefers an area with full sun and loose soil. Remove all weeds and replace the soil if needed to ensure good water permeability and avoid root rot. Wear gloves or use tongs when planting to prevent your fingers from getting pricked. You can also wrap the plant in a towel to help you move it.
Cultivation:HarvestDetail
Most fruits of hedge cactus are edible. Pick the fruit when they turn red. Avoid food safety issues by confirming the species with experts. Wear gloves or use scissors and other tools to harvest.

Common Pests & Diseases

Common issues for Hedge cactus based on 10 million real cases
Brown spot
Brown spot Brown spot Brown spot
This infection can cause brown spots or patches to appear on the plant.
Solutions: In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary. Organic options won’t kill the fungus, but will prevent it from spreading. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear. Spray a copper-based fungicidal soap on the leaves, coating the top and bottom leaf surfaces. Reapply as directed on the product label. Copper penetrates the leaf surface and prevents germination of spores so the fungus cannot spread. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.

Plant dried up
Plant dried up Plant dried up Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.

Low light
Low light Low light Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Solutions: Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed. Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn. Introduce appropriate artificial lighting. Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.

Stem rot
Stem rot Stem rot Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Solutions: If the plant is only infected a little, it can sometimes be saved. This mainly applies to houseplants that are grown in pots. Here's what to do. Remove the plant from the pot and gently shake off as much soil as possible. Using pruning tools that have been disinfected, remove any diseased foliage and roots. Be sure the new pot has good drainage holes and wash it with one part bleach and nine parts water to ensure that it is completely clean and sanitized. Dip the plant's roots in fungicide to kill off any remaining fungal spores before potting into the clean growing medium. Only water the plant when the top inch of the soil is dry and never let the plant sit in water. For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.

Brown spot
plant poor
Brown spot
This infection can cause brown spots or patches to appear on the plant.
Overview
Overview
Discolored spots on the foliage of plants are one of the most common disease problems people observe. These spots are caused by fungal and bacterial diseases, with most infections related to a fungal pathogen.
Brown spot can occurs on all houseplants, flowering ornamentals, vegetable plants, and leaves of trees, bushes, and shrubs. No plants are resistant to it, and the problem is worse in warm, wet environments. It can occur at any point in the life stage as long as leaves are present.
Small brownish spots appear on the foliage and enlarge as the disease progresses. In severe cases, the plant or tree is weakened when the lesions interrupt photosynthesis or cause defoliation.
Symptom Analysis
Symptom Analysis
In most cases, brown spot only affects a small percentage of the whole plant, appearing on a small amount of the leaves. A small infection only puts minor stress on the plant. However, if left untreated and the disease progresses over numerous seasons, it will severely impact the health and productivity of the infected specimen.
  • Sporulation begins (reproduction of the fungal spores), and tiny spots appear on leaves.
  • Placement is often random and scattered as diseases are spread through raindrops.
  • May appear on lower leaves and the interior of the plant where humidity is higher.
  • Brown spots enlarge and grow large enough to touch neighboring spots to form a more prominent blotch.
  • Leaf margins may turn yellow.
  • Tiny black dots (fruiting bodies of the fungi) appear in the dead spots.
  • Blotches grow in size until the entire leaf is brown.
  • The leaf falls off the plant.
Severe Symptoms
  • Partial or complete premature defoliation
  • Reduced growth
  • Increased susceptibility to pests and other diseases
Disease Cause
Disease Cause
Brown spot, or leaf spot, is a common descriptive term given to several diseases affecting the leaves of plants and trees. Around 85% of diseases exhibiting leaf spots are due to fungus or fungus-like organisms. Sometimes brown spot is caused by a bacterial infection, or insect activity with similar symptoms.
When conditions are warm and the leaf surfaces are wet, fungal spores being transported by wind or rain land on the surface and cling to it. They do not rupture the cell walls but grow in the space between the plant plasma membrane and the plant cell wall. As the spores reproduce, they release toxins and enzymes that cause necrotic spots (i.e., dead tissue) on the leaves, allowing the fungi to consume the products released when the cells degrade.
Solutions
Solutions
In minor cases of brown spot, there isn’t any need to treat the disease. However, if much of the foliage is affected and defoliation occurs, the plant will benefit from getting rid of the infection. It is recommended to start by applying organic treatment options, working up to the more potent synthetic, chemical fungicides if necessary.
Organic options won’t kill the fungus, but will prevent it from spreading.
  1. Dissolve ½ teaspoon of baking soda and one teaspoon of liquid soap in a gallon of water. Using a spray bottle, spray on tops and bottoms of leaves until the mixture drips off. Repeat every two weeks until existing spots stop enlarging and new spots no longer appear.

  3. Apply an all-purpose fungicide to the entire plant, following the label instructions carefully.
Prevention
Prevention
Like many other diseases, it is easier to prevent brown spot than cure it, and this is done through cultural practices.
  • Clear fall leaves from the ground before winter to minimize places where fungi and bacteria can overwinter.
  • Maintain good air movement between plants through proper plant spacing.
  • Increase air circulation through the center of plants through pruning.
  • Thoroughly clean all pruning tools after working with diseased plants.
  • Never dispose of disease plant material in a compost pile.
  • Avoid overhead watering to keep moisture off of the foliage.
  • Keep plants healthy by providing adequate sunlight, water, and fertilizer.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.

Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Low light
plant poor
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Overview
Overview
All plants require light, and if they do not receive it in the quantities that they require this distorts their growth in a process known as etiolation. In essence, etiolated plants are diverting all of their energy to growing taller in a desperate attempt to reach a position where they can meet their light requirements. Many other growth factors are harmed by this, and so light-deprived plants can become weak and distorted until they are almost unrecognizable. Low light symptoms are most commonly seen in houseplants, but outdoor specimens can also be affected.
Symptom Analysis
Symptom Analysis
Although symptoms will vary in different plants, the general symptoms of low light are easy to spot.
  1. Plant stems grow tall and lanky.
  2. There are less leaves, and both leaves and stems tend to be pale and insipid looking. This is due to a shortage of chlorophyll.
  3. All plant parts become weakened and may droop, as energy is diverted toward too-fast growth as the plant stretches itself toward any source of light.
Disease Cause
Disease Cause
Plants need sunlight in varying amounts for photosynthesis – a process that produces energy for growth and fruit and flower production. Low light causes a plant to divert all energy to upward (apical) growth in order to find better light. Plant hormones called auxins are transported from the actively-growing tip of the plant downwards, to suppress lateral growth. A drop in cellular pH triggers expansins, nonenzymatic cell wall proteins, to loosen cell walls and allow them to elongate. This elongation results in the abnormal lengthening of stems, especially internodes, or plant "legginess" which is observed in etoliated plants.
Solutions
Solutions
Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed.
  • Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn.
  • Introduce appropriate artificial lighting.
  • Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.
Prevention
Prevention
To avoid etiolation, provide an adequate amount of light from the beginning.
  1. Choose a location that matches each plant's ideal light needs. Many indoor plants do best in or near a south-facing window, which will provide the longest hours of sunlight. Flowering plants and those with colored leaves typically need more light than purely-green plants, as photosynthesis occurs in the green portions of leaves.
  2. Select plants with light needs that match a location's conditions. Some cultivars and varieties require less light than others.
  3. Use a grow light. Darker locations may require artificial illumination. A grow light may also become more necessary during winter, when sunlit hours are at their shortest.

Stem rot
plant poor
Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Overview
Overview
Stem rot is a serious disease and can affect many different types of plants. it can be particularly prevalent when the temperature of the soil is over 16 ℃ and there's a lot of moisture in the soil. This could be from unusually heavy rainfalls or too much irrigation. Once stem rot sets in, it's very difficult to get rid of the disease and most affected plants will have to be discarded. This is especially the case for vegetables, herbs, and other herbaceous plants that have soft stems. This is why it's important to ensure that the soil used for growing these plants is well-drained and that overwatering is avoided. Using good cultural practices also help in curbing these types of fungal diseases.
Symptom Analysis
Symptom Analysis
Plants that have been affected by stem rot will first display a yellowing of the lower leaves. This is followed by obvious wilting and stunted growth.
If the stem of the affected plant is examined closely, there will be some dark discolorations starting near the base and moving upward. If the roots of affected plants are examined, they will appear dark and mushy instead of white and healthy-looking. Eventually, the entire plant will wilt and die.
Disease Cause
Disease Cause
Stem rot is caused by a variety of soil-borne fungus pathogens. The type of fungus depends on the species of plant that is affected. Two fungi responsible for stem rot are Rhizoctonia and Fusarium. These fungal pathogens live in soil and migrate to the plant when conditions are optimum. This includes warm, humid weather and excessive soil moisture. Commonly, vegetable seedlings are affected by these fungi.
Sclerotinia sclerotiorum is another fungus that causes stem rot in plants. This fungus has a host range of over 350 different species of plants. Plants most susceptible to this fungus include many vegetable varieties such as cucumbers, beans, cilantro, carrots, cabbage, melons, lettuce, peas, onions, tomatoes, pumpkins, and squash. This fungus can produce different symptoms in different species. In some cases, the fungus causes irregular spots on stems and other plant material that appear water-soaked. On other plant species, the fungus appears as dry lesions that grow and girdle the stem of the plant.
The third type of fungus that causes stem rot is Phytophthora capsici. Plants that belong to the cucumber family are most susceptible to this fungal infection. This fungus manifests as water-soaked lesions on the stems that then turn brown and girdle the stem.
All of these fungal pathogens are transmitted to the plant by water splashing from the soil up onto the plant. That's because the fungal spores live in the soil where they wait for the right conditions to infect the plants.
Solutions
Solutions
If the plant is only infected a little, it can sometimes be saved. This mainly applies to houseplants that are grown in pots. Here's what to do.
  1. Remove the plant from the pot and gently shake off as much soil as possible.
  2. Using pruning tools that have been disinfected, remove any diseased foliage and roots.
  3. Be sure the new pot has good drainage holes and wash it with one part bleach and nine parts water to ensure that it is completely clean and sanitized.
  4. Dip the plant's roots in fungicide to kill off any remaining fungal spores before potting into the clean growing medium.
  5. Only water the plant when the top inch of the soil is dry and never let the plant sit in water.
For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.
Prevention
Prevention
For outdoor gardens:
  1. Raking the garden thoroughly in the springtime will help to cut down on pathogens that may be living in the soil.
  2. Using a copper fungicide on plants in the springtime will cut down on fungal growth and prevent the spread of infection.
  3. Placing a heavy layer of mulch on top of the soil will also prevent pathogens from splashing up onto the stems of plants.
  4. Place plants at the recommended spacing to encourage better air flow between them.
  5. Water plants at the base instead of overhead to prevent excessive moisture on foliage.
For indoor plants:
  1. Avoid overwatering houseplants and ensure the roots do not sit in water.
  2. Make sure that indoor plants receive adequate air circulation and light.

Common Problems

Why is its fleshy stem thinner and thinner as it grows?

more more
Thin stems may be caused by insufficient sunlight, insufficient water, or fertilizer deficiency. Move the pot to a brighter place, but avoid sunburn. Increase water and fertilizer.

How do I deal with root or stem rot?

more more
Excess water often leads to root and stem rot. Avoid accumulated water in soil. Prune rotten roots and stems and transplant to a new flowerpot in a well-ventilated place. The soil should be loose and air-permeable as far as possible.

Why doesn't my hedge cactus ever bloom?

more more
Firstly, it may not be time for the plant to bloom. Time from seedling to blooming can range between 2-20 years or longer. Secondly, the plant may need more sunlight, temperature or fertilizer. Increase the exposure to sunlight and fertilizer appropriately, supplement the fertilizer with phosphorus and potassium, or purchase special fertilizer for promoting blooming of hedge cactus.

Why does hedge cactus turn yellow?

more more
Hedge cactus turns yellow due to overwatering, insufficient sunlight, or pests. Hedge cactus does not require much water, and excess water leads to root anoxia and root rot. Generally, it does not need to be watered often. Water it only when the soil is completely dry. Remember to drain the water in the flowerpot tray. Sunlight can be increased, but avoid direct exposure to blazing sunlight to prevent sunburn. Remove a small amount of pests with alcohol. For large infestations, spray pesticide.
