What should I do if I water my Spiny pincushion cactus too much or too little?
Underwatered Spiny pincushion cactus
Spiny pincushion cactus and other succulents can endure long periods without water, so it’s unusual to find one of these suffering from underwatering. But, if you somehow forgot about your plant and neglected to water it for a month or more, you’ll probably find your Spiny pincushion cactus looking thirsty or with some leaf damage from lack of watering.
It is very easy to identify an underwatered Spiny pincushion cactus. The leaves will look shriveled, dry, and flat. Some may have dried up completely, turned brown and crispy, or dropped off the plant, starting with the lower leaves and moving upward as the dry conditions continue. And of course, the soil will be completely dried out.
If your Spiny pincushion cactus is thirsty and underwatered, give it plenty of water as soon as possible. Submerging the pot entirely in water for about 5-10 minutes is a good way to make sure the soil and plant are rehydrated properly. When you feel a sense of moisture on the surface of the soil with your finger, it means the watering is done properly. If there are dried out leaves still attached, go ahead and pluck them off to make room for new growth.
Overwatered Spiny pincushion cactus
Overwatering is dangerous to Spiny pincushion cactus and can be fatal to your plant if you don’t remedy the situation. Too much moisture over time leads to root rot, which prevents the roots from being able to absorb nutrients and water from the soil. Root rot occurs when wet conditions allow fungi and bacteria to flourish in the soil and feed on roots. When you find that it's overwatered, you'd better change the growing conditions, place it somewhere with more air ventilation and adjust water frequency, for example.
The symptoms of overwatering are yellow, swollen, and translucent leaves that may even burst open from being over-full with water. If the problem continues without being treated, leaves might turn brown or black, and fall off the plant at the slightest touch. Be sure to check the soil to determine if overwatering is the culprit, as some other issues can cause similar symptoms.
It’s a bit difficult (but not impossible) to save an overwatered plant. The key is catching it early before a lot of damage has occurred. If the roots become rotten, it is likely to kill the entire plant. If you suspect you have overwatered your Spiny pincushion cactus, the first step is to remove it from its pot and check the roots and soil.
After removing the plant from its pot, gently remove wet soil from around the roots and then rinse them clean in room-temperature water. This helps with removing fungus that might be lurking in the soil and allows you to get a better sense of how healthy the roots are. If your plant has already developed root rot, you will see roots that are dark brown or black, soft, mushy, or slimy.
If the majority of the roots are already affected by root rot, it may not be possible to save the plant. In this case, it is best to remove any healthy leaves and try to use these to propagate a new Spiny pincushion cactus. Luckily, this plant is easy to propagate even from a single leaf. If, on the other hand, only a portion of the roots have succumbed to rot and other healthy roots still remain, there is a chance it can be saved.
Use a sterilized cutting tool to remove any unhealthy-looking roots. Once you're left with only the firm, pale roots, it’s a good idea to dip them in a fungicide to kill off any remaining spores. After that you can repot your Spiny pincushion cactus in fresh, free-draining potting soil. While this does not always work to save a succulent with root rot, in most cases this plant will be able to make a full recovery and will put out new growth starting in the next growing season.

How often should I water my Spiny pincushion cactus?
There’s not a hard-and-fast rule for how often to water Spiny pincushion cactus. The best way to determine this is to check the soil and only water when it’s bone dry. You can either stick your finger in the pot or use a moisture meter to check the soil below the surface. When you plant it in a deep pot, you can do this with a stick or chopstick. If it feels even a little bit moist, wait a few days and check it again.
Most people will need to water Spiny pincushion cactus about every two weeks in summer and once a month in winter, but there are several factors that can change the frequency. The section below lists some considerations that can help you to determine how often to water.
Read More more
What should I consider when watering my Spiny pincushion cactus?
There are several environmental conditions that will affect how your Spiny pincushion cactus needs to be watered, including the container size, soil type, temperature, and humidity.
First off, the container and soil you use will determine how often to water and how much water to use each time. Be sure you use a container with plenty of drainage holes in the bottom so extra water can escape the pot. A small container has less room for soil, meaning it won’t hold as much moisture, while a larger pot will stay wet longer and need to be watered less often. It’s important not to keep your Spiny pincushion cactus in an oversized pot as this can easily lead to overwatering. When repotting, move to just one size larger than the current container. A shallow container works better than a deep one, since Spiny pincushion cactus has shallow root systems.
Spiny pincushion cactus will need to be watered less often in winter and more often in the active growing season in spring and autumn. During the winter, growth slows down considerably and the plant isn’t using much energy or water. There is less water lost to evaporation in cooler winter air, meaning that soil stays wet for much longer than it would in the summer.
This also applies to the general climate around your home. If you live in a humid location with a lot of rain, you will need to water less often than if you live in a dry, arid climate. Remember that conditions at the same geographic location can vary significantly with the season and the use of indoor heating and air conditioning.
Outdoor Planting
If Spiny pincushion cactus is planted in the ground, after establishing a root system, it shouldn’t need supplemental water beyond what it receives through precipitation and dew. But if there is a long dry period, you may want to water occasionally. In other areas where Spiny pincushion cactus can only be grown in a container, this plant can be moved outside in the spring and summer when the temperature is proper and then brought back inside when temperatures start to drop. A potted Spiny pincushion cactus kept outside usually needs more water than the same plant kept indoors, because there is a lot more sun exposure even on a shaded porch.

How to water Spiny pincushion cactus?
The best way to water Spiny pincushion cactus is to soak it thoroughly and then allow it to dry out before it gets watered again. Since this plant is somewhat drought tolerant, you can let it get quite dry before watering again. It is always better to give this type of plant too little water over too much.
When you water, make sure the soil gets thoroughly soaked throughout the whole pot. Don’t pour the water in just one spot, but rather try to go around the whole rim of the planter to be sure that it has a chance to get wet on all sides of the plant. The correct amount of water will depend on the size of your container and how much water your soil absorbs. Give your Spiny pincushion cactus enough water that it drains out from the drainage holes and then (ideally) leave the drained water in the saucer for about 20-30 minutes to absorb into dry pockets of soil. After that, discard any excess water that’s still in the saucer to avoid the soil getting waterlogged.
Bottom-watering is also an excellent method for the Spiny pincushion cactus, as you can be sure that the soil gets thoroughly moistened. This process involves placing the pot into a saucer of water and allowing the soil to absorb moisture through the drainage holes. You will know that the soil has absorbed enough water when the top layer is moist. This takes a bit more time than top-watering, but is almost foolproof in getting an even distribution of water throughout the pot.
The original habitat of Spiny pincushion cactus is relatively dry with little rain, but when it rains, the soil will be thoroughly moistened. So you can mimic this situation by bottom-watering your plant when the soil is totally dry. Deep soil bathing is better than frequent light watering for Spiny pincushion cactus.

Name story

Spiny pincushion cactus
The spiny pincushion cactus is one of those plants with a self-explanatory common name: it is a particularly small, round, plump little cactus that is covered in many sharp spines so that it resembles a pincushion. The genus “Mammilaria” is derived from the Latin word for ‘nipple’, a reference to the many bumpy tubercles that cover this type of cactus.

Usages

Garden Use
Spiny pincushion cactus produces showy flowers late in autumn or early winter. This drought-tolerant succulent is suitable for desert gardens, patio containers, and xeriscaping. As the fruit of this cactus is edible to birds, it attracts a great many species of them. Generally disease-free, it is also a popular houseplant.

Trivia and Interesting Facts

Mammillaria spinosissima has earned the Royal Horticultural Society's Award of Garden Merit and has been popularly cultivated since at least the early 1800s. Mammillaria spinosissima can grow up to 30 cm tall and usually reaches its full height after 5 to 10 years.

Common Pests & Diseases About Spiny pincushion cactus

Common issues for Spiny pincushion cactus based on 10 million real cases
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.
Flower withering
Flower withering Flower withering
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Longhorn beetles
Longhorn beetles Longhorn beetles
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Soil mold
Soil mold Soil mold
Soil mold
Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Solutions: Measures to take to remove soil mold: Physically remove mold/mushrooms - remove and dispose of mushrooms. To remove mold, scrape 1/8” of soil from the surface. Add a layer of sand or gravel - adding 1/4” of sand or gravel on top of the soil surface will discourage new fungal growth Sprinkle an antifungal treatment around the plants - this doesn't have to be a commercial fungicide, as many growers swear by all-natural remedies like cinnamon and baking soda Some types of mold contain toxins that can be harmful to humans or irritate those with allergies or asthma. Wear a dust mask while performing these tasks.

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.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions
Solutions
Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control.
Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees.
  • Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage.

Soil mold
Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Overview
Overview
If there is soil mold around the plants, this isn't necessarily a reason to panic. Mold can occur for several reasons. Most of the time, it's harmless. The microorganisms that exist in mold are, in fact, necessary for healthy plant life. That said, it can be unsightly and in some cases, harmful to certain plants. It's important to understand why mold might be forming. It is only after the potential causes have been identified that steps can be taken to stop mold from spreading or appearing in the future.
Symptom Analysis
Symptom Analysis
The most obvious sign of soil mold is, of course, mold observed on the surface of the soil. This can be fuzzy and white, yellow, or gray in color. Other symptoms may include:
  • Mushrooms
  • Wilted plants
  • Plants are stunted in growth
  • Soil has an odd "off" smell
  • Premature leaf drop or flower/blossom/fruit rot
  • Excess water is leaking from drainage holes
While soil mold doesn't always harm the growth of a plant, it can indicate the presence of a larger problem that needs to be addressed (and these problems can often harm plants).
Disease Cause
Disease Cause
There are several causes for soil mold. Understanding why mold is growing should be the first step in deciding on the best course of action.
Some potential causes include:
  • Overwatering - fungi consume excess water, so the presence of mold indicates that there is water that the plants aren't readily using
  • Poor drainage - this can be caused by dense, compacted soil, a lack of drainage holes, or an inadequate pot size
  • Poor air circulation - this is common in indoor-grown plants, especially in the winter when windows are closed
  • Contaminated soil - while all soil contains microorganisms, soil can contain fungal spores that lead to mold growth
  • Decomposing leaves on the soil surface feed the mold

Full sun
Spiny pincushion cactus flourishes in environments where it can receive an abundance of sunlight. While it can endure conditions with a bit less light, the energy it harvests from the sun greatly optimizes its growth. Originating from an environment bathed in sunlight, lack or excess of light can inhibit its health, causing pale coloration or sunburn.
Best Sunlight Practices
Temperature
0 - 43 ℃
The spiny pincushion cactus prefers a temperature range of 68 to 100 ℉ (20 to 38 ℃), which is consistent with its native growth environment in subtropical and tropical climates. During hot summers, it can tolerate temperatures up to 110 ℉ (43 ℃), but it is sensitive to sudden temperature drops in winter and needs to be kept above 50 ℉ (10 ℃) to avoid cold damage.
Temp for Healthy Growth
Transplant
6-12 inches
The prime time to transplant spiny pincushion cactus is during the warm months of early to mid-summer, as this allows the plant to acclimate and root well. Ensure the location is well-draining and receives plenty of sunlight. Be gentle while transplanting to avoid damaging the spines.
Transplant Techniques
Overwinter
0 - 43 ℃
A kiss of winter suits spiny pincushion cactus, whose native high-altitude Mexican habitats endure sharp temperature dips. This survivor evolved to mitigate moisture loss and resist frost. For effective spiny pincushion cactus winter care, gardeners should ensure dry, bright conditions, with temperatures remaining above freezing. Prolonged wet and cold spells can result in rot, so vigilance and timely intervention pays dividends in spiny pincushion cactus's winter wellness.
Winter Techniques

Name story

Spiny pincushion cactus
The spiny pincushion cactus is one of those plants with a self-explanatory common name: it is a particularly small, round, plump little cactus that is covered in many sharp spines so that it resembles a pincushion. The genus “Mammilaria” is derived from the Latin word for ‘nipple’, a reference to the many bumpy tubercles that cover this type of cactus.

Usages

Garden Use
Spiny pincushion cactus produces showy flowers late in autumn or early winter. This drought-tolerant succulent is suitable for desert gardens, patio containers, and xeriscaping. As the fruit of this cactus is edible to birds, it attracts a great many species of them. Generally disease-free, it is also a popular houseplant.

Trivia and Interesting Facts

Mammillaria spinosissima has earned the Royal Horticultural Society's Award of Garden Merit and has been popularly cultivated since at least the early 1800s. Mammillaria spinosissima can grow up to 30 cm tall and usually reaches its full height after 5 to 10 years.

Common Pests & Diseases About Spiny pincushion cactus

Common issues for Spiny pincushion cactus based on 10 million real cases
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.

Flower withering
Flower withering Flower withering Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.

Longhorn beetles
Longhorn beetles Longhorn beetles Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Solutions: Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control. Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees. Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree. Contact an arborist for best control practices regarding infected trees. To properly control longhorn beetles, all host plants in a given area must be treated. Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.

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.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions
Solutions
If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface.
In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well.
If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Longhorn beetles
plant poor
Longhorn beetles
The longhorn beetle is a medium- to large-sized insect with very long antennae and strong jaws. Both its adult and larval stages gnaw on tree trunks, leaving small, round holes.
Overview
Overview
Longhorn beetles are characterized by extremely long antennae which are often as long as, or longer, than the beetle's body. Adult longhorn beetles vary in size, shape, and coloration, depending upon the species. They may be 6 to 76 mm long. The larvae are worm-like with a wrinkled, white to yellowish body and a brown head.
Longhorn beetles are active throughout the year, but adults are most active in the summer and fall. Larvae feed on wood throughout the year.
Both larvae and adults feed on woody tissue. Some of the most susceptible species include ash, birch, elm, poplar, and willow.
If left untreated, longhorn beetles can kill trees.
Symptom Analysis
Symptom Analysis
Longhorn beetles are attracted to wounded, dying, or freshly-cut hardwood trees. Adults lay their eggs in the spring, summer, and fall on the bark of greenwood. There may be sap around egg-laying sites.
Once the eggs hatch, larvae called round-headed borers burrow into the trunk to feed. They may tunnel for one to three years depending on the wood's nutritional content. As the larvae feed, they release sawdust-like frass at the base of the tree.
Eventually, the larvae turn into pupae and then adults. When the adults emerge, they leave 1 cm holes in the bark on their way out. Adults feed on leaves, bark, and shoots of trees before laying eggs.
After a few years of being fed upon by longhorn beetles, a tree will begin losing leaves. Eventually, it will die.
Solutions
Solutions
Some longhorn beetles species are native insects, and they cause little damage. Therefore, these don't warrant control.
Other longhorn beetles species are invasive pests that were recently introduced from other areas. These species can cause a great deal of damage to hardwood trees.
  • Apply an insecticide containing imidacloprid as a soil injection or trunk injection following product instructions. This will enter into new grow and kill adults who feed on foliage. This will not help save trees that are already infested with large amounts of larvae, but it will save trees located near an infested tree.
  • Contact an arborist for best control practices regarding infected trees.
  • To properly control longhorn beetles, all host plants in a given area must be treated.
  • Contact a local extension agent or state agency. Tracking the spread of longhorn beetles is a key component of their control.
Prevention
Prevention
  • Keeping trees healthy, uninjured, and unstressed will help prevent beetle infestation. Water trees appropriately, giving neither too much nor too little.
  • Check with local tree companies about which tree species have fewer problems.
  • Avoid moving firewood as this can introduce exotic longhorn beetles.
  • Routine spraying of persistent, broad-spectrum insecticides will help prevent re-infestation of previously affected trees or infestation of unaffected trees.

Soil mold
plant poor
Soil mold
Moist environments may encourage the growth of mushrooms or other fungi at the soil's surface that do not affect the health of the plant.
Overview
Overview
If there is soil mold around the plants, this isn't necessarily a reason to panic. Mold can occur for several reasons. Most of the time, it's harmless. The microorganisms that exist in mold are, in fact, necessary for healthy plant life. That said, it can be unsightly and in some cases, harmful to certain plants. It's important to understand why mold might be forming. It is only after the potential causes have been identified that steps can be taken to stop mold from spreading or appearing in the future.
Symptom Analysis
Symptom Analysis
The most obvious sign of soil mold is, of course, mold observed on the surface of the soil. This can be fuzzy and white, yellow, or gray in color. Other symptoms may include:
  • Mushrooms
  • Wilted plants
  • Plants are stunted in growth
  • Soil has an odd "off" smell
  • Premature leaf drop or flower/blossom/fruit rot
  • Excess water is leaking from drainage holes
While soil mold doesn't always harm the growth of a plant, it can indicate the presence of a larger problem that needs to be addressed (and these problems can often harm plants).
Disease Cause
Disease Cause
There are several causes for soil mold. Understanding why mold is growing should be the first step in deciding on the best course of action.
Some potential causes include:
  • Overwatering - fungi consume excess water, so the presence of mold indicates that there is water that the plants aren't readily using
  • Poor drainage - this can be caused by dense, compacted soil, a lack of drainage holes, or an inadequate pot size
  • Poor air circulation - this is common in indoor-grown plants, especially in the winter when windows are closed
  • Contaminated soil - while all soil contains microorganisms, soil can contain fungal spores that lead to mold growth
  • Decomposing leaves on the soil surface feed the mold
Solutions
Solutions
Measures to take to remove soil mold:
  • Physically remove mold/mushrooms - remove and dispose of mushrooms. To remove mold, scrape 1/8” of soil from the surface.
  • Add a layer of sand or gravel - adding 1/4” of sand or gravel on top of the soil surface will discourage new fungal growth
  • Sprinkle an antifungal treatment around the plants - this doesn't have to be a commercial fungicide, as many growers swear by all-natural remedies like cinnamon and baking soda
Some types of mold contain toxins that can be harmful to humans or irritate those with allergies or asthma. Wear a dust mask while performing these tasks.
Prevention
Prevention
Follow these practices to prevent soil mold from forming.
  • Limit moisture - avoid keeping soil damp, and allow it to dry out between waterings. Watering from the bottom of pots with drainage can allow the surface soil to stay dry.
  • Provide aeration - increase airflow around the plants using a fan or wind.
  • Repot - if the container is too small or lacks proper drainage, transplant the plant into a new, better-draining container.
  • Apply a layer of sand - apply 6 mm of sand on top of soil.
  • Use potting mix - when planting, only use potting mix instead of regular soil, as this is specially formulated for the proper moisture retention.

Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Symptoms of Insufficient Light in %s
Spiny pincushion cactus is a beloved choice for indoor gardening, and they require strong light to thrive. However, when placed in rooms with suboptimal lighting, they may develop symptoms of light deficiency.

(Symptom details and solutions)
Leggy or sparse growth
The spaces between leaves or stems of your spiny pincushion cactus may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Slower or no new growth
Spiny pincushion cactus enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Symptoms of Excessive light in %s
Spiny pincushion cactus require strong light to thrive, and some are remarkably resilient to sun exposure, rarely suffering from sunburn.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

Just like people, each plant has its own preferences. Learn about your plants' temperature needs and create a comforting environment for them to flourish. As you care for your plants, your bond with them will deepen. Trust your intuition as you learn about their temperature needs, celebrating the journey you share. Lovingly monitor the temperature around your plants and adjust their environment as needed. A thermometer can be your ally in this heartfelt endeavor. Be patient and gentle with yourself as you explore your plants' temperature needs. Cherish your successes, learn from challenges, and nurture your garden with love, creating a haven that reflects the warmth of your care.
Essentials
The spiny pincushion cactus prefers a temperature range of 68 to 100 ℉ (20 to 38 ℃), which is consistent with its native growth environment in subtropical and tropical climates. During hot summers, it can tolerate temperatures up to 110 ℉ (43 ℃), but it is sensitive to sudden temperature drops in winter and needs to be kept above 50 ℉ (10 ℃) to avoid cold damage.
Regional wintering strategies
Spiny pincushion cactus is a heat-loving plant that gradually stops growing and enters a dormant state during the winter. When the outdoor temperature drops below {Tolerable_growing_temperature_min}, it should be moved indoors for cultivation. Choose a location near a south-facing window to provide as much sunlight as possible. If there is insufficient natural light, supplemental lighting can be used. When the temperature falls below {Suitable_growth_temperature_min}, the plant's growth slows down, and watering should be reduced or stopped to prevent root rot. For Spiny pincushion cactus grown outdoors, watering should be completely halted during low temperatures. If feasible, you can set up a temporary greenhouse for insulation or use materials such as plastic film or fabric to wrap the plant during cold temperatures.
Important Symptoms
Symptoms of Low Temperature in %s
Spiny pincushion cactus thrives in high temperatures and is not tolerant of low temperatures. It grows best when the temperature is above {Suitable_growth_temperature_min}. During winter, it should be kept above {Tolerable_growing_temperature_min}. When the temperature falls below {Limit_growth_temperature}, the plant may become weak, wilt, and be prone to root rot. In cases of mild frost damage, there may not be any initial symptoms, but after a week, the plant will gradually wither.
Solutions
Trim off the frostbitten areas, paying attention to whether the roots have rotted. If the roots have rotted, they need to be cut off, and the plant can be propagated through cuttings. Immediately move indoors to a warm environment and place the plant near a south-facing window to ensure ample sunlight. If there is insufficient light, you can use supplemental lighting.
Symptoms of High Temperature in %s
During summer, Spiny pincushion cactus should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the plant's growth will cease, it will experience water loss, wilting, and becomes more susceptible to sunburn.
Solutions
Remove the sunburned and rotten parts. Shield the plant from afternoon sunlight until it recovers and starts growing again. For plants with root rot, stop watering until new roots begin to emerge.

Why is my transplanted spiny pincushion cactus wilting?
Spiny pincushion cactus may wilt due to transplant shock, insufficient water, or excessive sunlight. Ensure balanced watering and position it in a place with filtered sunlight.
What kind of soil should I use to transplant spiny pincushion cactus?
Spiny pincushion cactus prefers a well-draining soil type. A cactus mix or a blend of regular potting soil and sharp sand or fine grit is suitable.
Can I transplant spiny pincushion cactus in a pot without drainage holes?
It's not recommended. Spiny pincushion cactus needs well-drained soil to prevent root rot. Pots without drainage holes can retain too much water.

Wait for a few days before watering newly transplanted spiny pincushion cactus to allow the roots to adjust and heal from any transplant damage.
How do I handle spiny pincushion cactus while transplanting to avoid prickling?
Use thick gloves or wrap the spiny pincushion cactus in several layers of newspaper when handling it. This will protect your hands from the spines.

Choose a pot that's slightly larger than the root ball of spiny pincushion cactus. Too large a pot may retain excess water and cause root problems.
How deep should I plant spiny pincushion cactus during transplanting?
The spiny pincushion cactus should be planted at the same depth it was in its previous pot. The top of the root ball should be level with the soil surface.
Why are the lower spines of my transplanted spiny pincushion cactus turning yellow?
Yellowing spines could indicate overwatering. Ensure your spiny pincushion cactus isn't sitting in water, and let the soil dry thoroughly between waterings.
