Rosa chinensis
Also known as: Bengal rose
The china rose (Rosa chinensis) is a Southwest China native. The plant has been cultivated for so long that it has become hard to tell the difference between wild and cultivated varieties. With medium-sized clusters of flowers and a long blooming season, it is easy to see why the china rose was chosen as the basis for many rose hybrids.

Care Guide for China rose

China rose is a very drought-tolerant type of rose, but it still benefits from frequent watering during its flowering time. Water the lower section of the plant and the surrounding soil, without wetting the leaves, if possible. For roses planted in the ground, water until the area seems waterlogged and a small puddle forms around the stems. Water again when the top layer of soil feels dry.
Fertilization
Fertilization
See Details
Fertilize your china rose with a balanced liquid fertilizer every two weeks during the growing period. Dilute the fertilizer into the water that you use for normal watering. You can also apply manure or garden compost in spring, during planting. Roses planted in containers or pots should be fertilized more often than those planted in the ground.
Trim the dead, diseased, overgrown branches in winter.

What's the best method to water my China rose?
You might want to put a garden hose at the plant base to ensure that you're promoting excellent root development. Avoid directly spraying the leaves, and know that the leaves will require more watering if they are outdoors and facing direct sunlight. You can also use bubblers that you can put on to each plant to moisten the roots. Also, use soaker hoses that can cover the entire garden or bed when adding or removing plants to push the roots deeply. Drain any excess water and wait for the soil to dry before watering. Water at ground level to prevent diseases. On a sunny day, you might want to spray the entire bush with water. Whether potted or in-ground, please remember China rose prefers deep watering over light sprinkling.

What should I do if I water China rose too much/too little?
An overwatered China rose can start to have leaves that turn yellow, drop off and wilt. The plant can also look dull and unhealthy, with signs of mushy stems. When they are beginning to show these signs, it's best to adjust your schedule whenever possible.
The wilting can also be a sign of under watering as well. You might see that the leaves begin to turn crispy and dry while the overwatered ones will have soft wilted leaves. Check the soil when it is dry and watering is not enough, give it a full watering in time. Enough water will make the China rose recover again, but the plant will still appear dry and yellow leaves after a few days due to the damaged root system. Once it return to normal, the leave yellowing will stop .
Always check the moisture levels at the pot when you have the China rose indoors. Avoid overwatering indoors and see if there are signs of black spots. If these are present, let the soil dry in the pot by giving it a few days of rest from watering.
Overwatering can lead to root rot being present in your plant. If this is the case, you might want to transfer them into a different pot, especially if you see discolored and slimy roots. Always prevent root rot as much as possible, and don't let the soil become too soggy.
You should dig a little deeper when you plant your China rose outdoors. When you check with your fingers and notice that the soil is too dry, it could mean underwatering. Adequate watering is required to help the plant recover.

How often should I water my China rose?
The China rose likes deep and infrequent watering. You would want to soak them in a gallon of water each time, especially when they are planted in pots. The water storage of flower pots is limited and the soil will dry out faster. Watering is required every 3 to 5 days when living in a cold region. Water it early in the morning when the soil is dry, outdoors or indoors. You can also determine if watering is needed by checking the soil inside. When the top 2-3 inches of soil is dry, it is time to give the plant a full watering. During hot days, you may need to check the moisture daily, as the heat can quickly dry out the soil in the pot.
Irrigation of the soil is also required if you have a garden. When you live in a hot climate, you might want to water once a week. Only water when you notice that about 2 to 3 inches of soil become too dry outdoors or indoors. Consider the amount of rainwater on the plant and ensure not to add to it to prevent root rot.You may not need additional watering of the plants if there is a lot of rainfall.China rose generally grows during spring and fall. When they are outdoors, you need to add mulch about 3 to 4 inches deep to conserve more water.
You need to water the plants more frequently in sandy soil because this type tends to drain faster. However, with the clay one, you need to water this less frequently where you could go for 2-3 days to dry the plant and not develop any root rot. You could mark the date on the calendar whenever you water and when you notice that the leaves are starting to droop. This can mean that you might be a day late.

How much water do I need to give my China rose?
The China rose generally needs about a gallon of water each schedule,With the potted plants, you might want to water them deeply until you see that the water is dripping at the bottom of the pot. Then, wait for the soil to dry before watering them again. You can use a water calculator or a moisture meter to determine the amount you've given to your plant in a week. Provide plenty of water, especially in the flowering period, but let the moisture evaporate afterwards to prevent root rot.
If China rose is planted outdoor with adequate rainfall, it may not need additional watering. When China rose is young or newly planted, make sure it gets 1-2 inches of rain per week. As China rose continues to grow, it can survive entirely on rainfall. Only when the weather is too hot, or when there is no rainfall at all for 2-3 weeks, then consider giving China rose a full watering during the cooler moment of the day to prevent the plant from suffering from high heat damage. Additional watering will be required during persistent dry spells.

Should I adjust the watering frequency for my China rose according to different seasons or climates?
The China rose needs outdoors come from rain, with only persistent dry weather requiring watering. Throughout the spring and fall growing seasons, the soil needs to be kept moist but not soggy, and alternating dry and moist soil conditions will allow the China rose to grow well. Throughout the summer, hot weather can cause water to evaporate too quickly, and if there is a lack of rainfall, you will need to water more frequently and extra to keep it moist.
Usually, the China rose will need less water during the winter. Since the China rose will drop their leaves and go dormant, you can put them into a well-draining but moisture-retentive soil mixture like the terracotta to help the water evaporate quicker. Once your China rose growing outdoors begins to leaf out and go dormant, you can skip watering altogether and in most cases China rose can rely on the fall and winter rains to survive the entire dormant period.
After the spring, you can cultivate your China rose and encourage it to grow and bloom when the temperature becomes warmer.This plant is not generally a fan of ponding or drought when flowering. You must ensure that the drainage is good at all times, especially during the winter.
When the plant is in a pot, the plant has limited root growth. Keep them well-watered, especially if they are planted in pots during summer. They don't like cold and wet roots, so provide adequate drainage, especially if they are still growing.
It's always best to water your China rose’s diligently. Get the entire root system into a deep soak at least once or twice a week, depending on the weather. It's best to avoid shallow sprinkles that reach the leaves since they generally encourage the growth of fungi and don't reach deep into the roots. Don't allow the China rose’s to dry out completely in the fall or winter, even if they are already dormancy.
Don't drown the plants because they generally don't like sitting in water for too long. They can die during winter if the soil does not drain well. Also, apply mulch whenever possible to reduce stress, conserve water, and encourage healthy blooms.

What should I be careful with when I water my China rose in different seasons, climates, or during different growing periods?
If planting in the ground, China rose mostly relies on rain. However, if there is no rainfall for 2-3 weeks, you may need to give proper consideration to giving the plants a deep watering. If watering China rose in summer, you should try to do it in the morning. A large temperature difference between the water temperature and the root system can stress the roots. You need to avoid watering the bushes when it's too hot outside. Start mulching them during the spring when the ground is not too cold.
The age of the plants matter. Lack of water is one of the most common reasons the newly planted ones fail to grow. After they are established, you need to ease off the watering schedule.
Reduce watering them during the fall and winter, especially if they have a water-retaining material in the soil. The dry winds in winter can dry them out, and the newly planted ones can be at risk of drought during windy winter, summer, and fall. Windy seasons mean that there's more watering required. The ones planted in the pot tend to dry out faster, so they need more watering. Once you see that they bloom less, the leaves begin to dry up.
Potted plants are relatively complex to water and fluctuate in frequency. Always be careful that the pot-planted plant don't sit in the water. Avoid putting them in containers with saucers, bowls, and trays. Too much watering in the fall can make the foliage look mottled or yellowish. It's always a good idea to prevent overwatering them regardless of the current climate or season that you might have. During the months when China rose begins to flower, you might want to increase the watering frequency but give it a rest once they are fully grown.
Give them an adequate amount of water once every 3 to 5 days but don't give them regular schedules. Make sure the soil is dry by sticking your finger in the pot, or use a moisture meter if you're unsure if it's the right time. Too much root rot can cause them to die, so be careful not to overwater or underwater regardless of the climate or season you have in your area.

Why is watering my China rose important?
Watering the China rose helps transport the needed nutrients from the soil to the rest of the plant. The moisture will keep this species healthy if you know how much water to give. The watering requirements will depend on the weather in your area and the plant's soil.
The China rose thrives on moist soil, but they can't generally tolerate waterlogging. Ensure to provide enough mulch when planted on the ground and never fall into the trap of watering too little. They enjoy a full can of watering where the water should be moist at the base when they are planted in a pot to get the best blooms.
If they are grown as foliage, you need to water them up to a depth of 10 to 20 inches so they will continue to grow. If it's raining, refrain from watering and let them get the nutrients they need from the rainwater.

Common Pests & Diseases

Common issues for China rose based on 10 million real cases
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.
Wilting after blooming
Wilting after blooming Wilting after blooming
Wilting after blooming
Flowers may wither for a variety of reasons.
Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
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.
Leaf beetles
Leaf beetles Leaf beetles
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Solutions: For less serious cases: Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread. To treat more serious infestations: Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Black spot
Black spot Black spot
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Solutions: Some steps to take to address black spot include: Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves. Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash. Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil. Use a spreader in the fungicide spray to ensure better coverage.
Nutrient deficiencies
Nutrient deficiencies Nutrient deficiencies
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

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.

Wilting after blooming
plant poor
Wilting after blooming
Flowers may wither for a variety of reasons.
Overview
Overview
Wilting after blooming is sometimes a natural aging process of the flower, while other times it may indicate a problem. Orchids, for example, can bloom for anywhere from two weeks to three months, so wilting after a few days signals a problem for most varieties. This can happen to virtually any ornamental flowering plant, but those with shallow roots and limited tolerance for drought, full sun, and low humidity are more susceptible.
This is a common problem, and often has an easy fix. Sometimes, however, it is the result of more serious causes such as pests or disease of the root system.
Symptom Analysis
Symptom Analysis
  • At first, flowers may look a little limp.
  • Petals may start to appear dried out and turn brown.
  • Eventually they may drop off the plant all together.
Disease Cause
Disease Cause
Wilting blooms can be a sign of an unhealthy root system. Any condition that prevents the plant from absorbing enough water and nutrition can result in wilting blooms and sometimes other symptoms. If the plant doesn’t have enough water, it cannot maintain appropriate pressure within stems, leaves, and blooms, causing them to wilt.
This can result from physical damage – for example from root breakage during re-potting or attack by insects like cutworms. If you recently re-potted your plant, physical damage to the roots is a likely cause. If you see insects, they may be eating leaves, roots, or flowers. Fungal infections can also cause root rot and damage, preventing water and nutrient uptake.
Finally, wilting blooms can result simply from age. If no other symptoms are visible, it may simply signal the natural end of the flower’s lifespan. If it seems premature, this may be caused by environmental factors: water, humidity, light, or stress. Under-watering is a common cause. Similarly, plants adapted to high humidity dry out easily when humidity is low, like during winter or in dry climates. Too much light can also stress plants that need shade, causing blooms to wilt.
Solutions
Solutions
  • Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water.
  • Water according to recommendations for each plant's species.
  • Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too.
  • Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants.
  • Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
Prevention
Prevention
  • Read up on moisture, light, and soil type preferences for each plant to avoid underwatering, incorrect light levels, or other conditions that can cause wilting blooms.
  • Avoid re-potting during the flowering period. This causes additional stress on the plants because they need to repair root damage and adapt to the new micro-environment, all of which can result in wilting.
  • One other potential cause is ethylene gas, a plant hormone related to ripening. Some fruits and vegetables emit ethylene, especially bananas. Apples, grapes, melons, avocados, and potatoes can also give it off, so keep flowering plants away from fresh produce.

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.

Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
Prevention
To prevent infestations of leaf beetles, follow these practices.
  1. Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
  2. Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
  3. Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
  4. Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Black spot
plant poor
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Overview
Overview
Black spot is a fungus that largely attacks leaves on a variety of ornamental plants, leaving them covered in dark spots ringed with yellow, and eventually killing them. The fungus is often simply unsightly, but if it infects the whole plant it can interfere with photosynthesis by killing too many leaves. Because of this, it is important to be aware of the best methods for preventing and treating this diseases should it occur in the garden.
Symptom Analysis
Symptom Analysis
Here are a few of the most common symptoms of black spot:
  • The plant has developed small black spots along the leaves.
  • These spots be small, circular, and clustered together, or they may have a splotchy appearance and take up large portions of the leaves.
  • The fungus may also affect plant canes, where lesions start purple and then turn black.
  • The plant may suffer premature leaf drop.
Though most forms of black spot fungus pose little risk to a plant's overall health, many gardeners find them unsightly. Severe cases can also weaken a plant, so it becomes more susceptible to other pathogens and diseases.
Disease Cause
Disease Cause
Black spot is spread by various types of fungi, which differ slightly depending on whether they are in their sexual or asexual stages.
The fungal spores linger over the winter in fallen leaves and lesions on canes. In the spring, the spores are splashed up onto the leaves, causing infection within seven hours of moisture and when temperatures range between 24 to 29 ℃ with a high relative humidity.
In just two weeks, thousands of additional spores are produced, making it easy for the disease to infect nearby healthy plants as well.
There are several factors that could make a plant more likely to suffer a black spot infection. Here are some of the most common:
  • Exposure to infected plants or mulch (the fungus overwinters on dead leaves)
  • Weakening from physical damage, pest infestation or other infections.
  • Increased periods of wet, humid, warm weather – or exposure to overhead watering
  • Plants growing too close together
Solutions
Solutions
Some steps to take to address black spot include:
  • Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves.
  • Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash.
  • Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil.
  • Use a spreader in the fungicide spray to ensure better coverage.
Prevention
Prevention
Here are a few tips to prevent black spot outbreaks.
  • Purchase resistant varieties: Invest in fungus-resistant plant varieties to reduce the chances for black spot diseases.
  • Remove infected plant debris: Fungi can overwinter in contaminated plant debris, so remove all fallen leaves from infected plants as soon as possible.
  • Rake and discard fallen leaves in the fall.
  • Prune regularly.
  • Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback. Adding a layer of mulch to the soil will also reduce splashing.
  • Grow plants in an open, sunny locations so the foliage dries quickly.
  • Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation.
  • Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
  3. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
  4. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Common Pests & Diseases

Common issues for China rose based on 10 million real cases
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.

Flowers may wither for a variety of reasons.
Solutions: Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water. Water according to recommendations for each plant's species. Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too. Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants. Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.

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.

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.

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.

Wilting after blooming
plant poor
Wilting after blooming
Flowers may wither for a variety of reasons.
Overview
Overview
Wilting after blooming is sometimes a natural aging process of the flower, while other times it may indicate a problem. Orchids, for example, can bloom for anywhere from two weeks to three months, so wilting after a few days signals a problem for most varieties. This can happen to virtually any ornamental flowering plant, but those with shallow roots and limited tolerance for drought, full sun, and low humidity are more susceptible.
This is a common problem, and often has an easy fix. Sometimes, however, it is the result of more serious causes such as pests or disease of the root system.
Symptom Analysis
Symptom Analysis
  • At first, flowers may look a little limp.
  • Petals may start to appear dried out and turn brown.
  • Eventually they may drop off the plant all together.
Disease Cause
Disease Cause
Wilting blooms can be a sign of an unhealthy root system. Any condition that prevents the plant from absorbing enough water and nutrition can result in wilting blooms and sometimes other symptoms. If the plant doesn’t have enough water, it cannot maintain appropriate pressure within stems, leaves, and blooms, causing them to wilt.
This can result from physical damage – for example from root breakage during re-potting or attack by insects like cutworms. If you recently re-potted your plant, physical damage to the roots is a likely cause. If you see insects, they may be eating leaves, roots, or flowers. Fungal infections can also cause root rot and damage, preventing water and nutrient uptake.
Finally, wilting blooms can result simply from age. If no other symptoms are visible, it may simply signal the natural end of the flower’s lifespan. If it seems premature, this may be caused by environmental factors: water, humidity, light, or stress. Under-watering is a common cause. Similarly, plants adapted to high humidity dry out easily when humidity is low, like during winter or in dry climates. Too much light can also stress plants that need shade, causing blooms to wilt.
Solutions
Solutions
  • Check the soil or potting medium. Coarse textures can allow water to drain too rapidly, preventing the plant from taking up enough. If the soil and roots seem very dry, add sphagnum moss or other mediums that hold water.
  • Water according to recommendations for each plant's species.
  • Low humidity can be corrected by misting the plant regularly or placing it near a humidifier. Keeping it near other plants helps, too.
  • Keep the environment consistent in terms of temperature, humidity, and lighting. Keep it away from vents, heaters, and air conditioners, and avoid moving it to locations where it will experience a temperature shock. Hot, dry heat, and cold drafts are problematic for many plants.
  • Especially if the plant is outside, it could be experiencing heat or light stress. Try moving it to a shadier location.
Prevention
Prevention
  • Read up on moisture, light, and soil type preferences for each plant to avoid underwatering, incorrect light levels, or other conditions that can cause wilting blooms.
  • Avoid re-potting during the flowering period. This causes additional stress on the plants because they need to repair root damage and adapt to the new micro-environment, all of which can result in wilting.
  • One other potential cause is ethylene gas, a plant hormone related to ripening. Some fruits and vegetables emit ethylene, especially bananas. Apples, grapes, melons, avocados, and potatoes can also give it off, so keep flowering plants away from fresh produce.

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.

Leaf beetles
plant poor
Leaf beetles
Leaf beetles are a class of colored insects 1 to 2 cm in size. They gnaw on leaves and petals resulting in small, round holes scattered over the surface.
Overview
Overview
Leaf beetles range in size from 1.5 mm to 2 cm. Both adult beetles and their larvae eat the leaves of many different types of plants. There are over 35,000 different species of leaf beetles, in a variety of colors including gold, green, yellow-striped, and red striped. Some of these have been mistaken for ladybirds because of their shape and coloring. They can be oval, round, or elongated in shape. These insect pests are most active in spring and summer.
If not controlled, leaf beetles can do a lot of damage to vegetable crops and ornamental plants. They feed on the leaves, flowers, stems, roots, and fruits of different plants. They can fly, which means it's easy for them to move from one plant to another. Some species of leaf beetles only target one specific crop, while others will target many different types of plants. Although a lot of the damage that they cause is cosmetic, an infestation can weaken a plant and leave it prone to other more problematic diseases.
Symptom Analysis
Symptom Analysis
The first signs of a leaf beetles infestation are small visible holes in leaves. Leaves then become discolored and dark beetle droppings can be seen. As the leaves turn yellow and brown, they will drop off the plant onto the ground. Some leaves will appear skeletonized with only the veins still remaining.
Infestation begins in spring, when the adult beetles emerge from the soil and lay their eggs on the leaves of plants. When these eggs hatch, the young nymphs start munching on the leaves as they grow up. Once leaf beetles are large and mature, they'll fall to the ground and pupate in the soil over winter before starting the cycle all over again.
Leaf beetles also eat holes in fruits and vegetables. These can be seen as small round holes that sometimes have a larger brown area surrounding them.
Solutions
Solutions
For less serious cases:
  1. Remove beetles, nymphs, and eggs. Remove all life stages of the beetles and kill them by placing them in a bucket of warm, soapy water. This can be done more easily by placing the bucket under affected leaves and shaking the plant. This method is most effective in the afternoon when leaf beetles are more active. Always dispose of insects in a sealed bag or container to avoid escape and spread.
To treat more serious infestations:
  1. Apply organic insecticides. Use naturally-derived insecticides before moving on to synthetic insecticides. Neem oil and pyrethrum are naturally-derived insecticides that should be applied following label instructions.
  2. Apply synthetic insecticides. Examples of insecticides effective for leaf beetles include carbaryl, permethrin, and bifenthrin. Apply insecticides according to label instructions.
Prevention
Prevention
To prevent infestations of leaf beetles, follow these practices.
  1. Regularly check for beetles. To prevent large pest infestations, be proactive about frequently checking plants for pests and removing them quickly.
  2. Clear debris. Clear weeds and debris to remove areas where these beetles may overwinter and hide.
  3. Attract natural predators. Birds and other insects, such as wasps and ladybugs, are effective natural predators of leaf beetles. Encourage them to visit by including a diverse array of plants to provide habitat and food. Also, avoid applying broad-spectrum herbicides that can harm and kill beneficial insects.
  4. Plant aromatic herbs like mint, garlic, or rosemary, as these can repel leaf beetles.

Black spot
plant poor
Black spot
Infection by the black spot pathogen causes black spots or patches to appear on leaves.
Overview
Overview
Black spot is a fungus that largely attacks leaves on a variety of ornamental plants, leaving them covered in dark spots ringed with yellow, and eventually killing them. The fungus is often simply unsightly, but if it infects the whole plant it can interfere with photosynthesis by killing too many leaves. Because of this, it is important to be aware of the best methods for preventing and treating this diseases should it occur in the garden.
Symptom Analysis
Symptom Analysis
Here are a few of the most common symptoms of black spot:
  • The plant has developed small black spots along the leaves.
  • These spots be small, circular, and clustered together, or they may have a splotchy appearance and take up large portions of the leaves.
  • The fungus may also affect plant canes, where lesions start purple and then turn black.
  • The plant may suffer premature leaf drop.
Though most forms of black spot fungus pose little risk to a plant's overall health, many gardeners find them unsightly. Severe cases can also weaken a plant, so it becomes more susceptible to other pathogens and diseases.
Disease Cause
Disease Cause
Black spot is spread by various types of fungi, which differ slightly depending on whether they are in their sexual or asexual stages.
The fungal spores linger over the winter in fallen leaves and lesions on canes. In the spring, the spores are splashed up onto the leaves, causing infection within seven hours of moisture and when temperatures range between 24 to 29 ℃ with a high relative humidity.
In just two weeks, thousands of additional spores are produced, making it easy for the disease to infect nearby healthy plants as well.
There are several factors that could make a plant more likely to suffer a black spot infection. Here are some of the most common:
  • Exposure to infected plants or mulch (the fungus overwinters on dead leaves)
  • Weakening from physical damage, pest infestation or other infections.
  • Increased periods of wet, humid, warm weather – or exposure to overhead watering
  • Plants growing too close together
Solutions
Solutions
Some steps to take to address black spot include:
  • Prune away any infected leaves, cleaning the pruners between plants with a 10% bleach solution so that the fungus does not spread to healthy leaves.
  • Don't compost pruned plant parts as the spores can linger in the soil for a long period of time - instead, dispose of them in the trash.
  • Use an approved fungicide such as Trifloxystrobin, Chlorothalonil, Maneb, or Myclobutanil.
  • Use a spreader in the fungicide spray to ensure better coverage.
Prevention
Prevention
Here are a few tips to prevent black spot outbreaks.
  • Purchase resistant varieties: Invest in fungus-resistant plant varieties to reduce the chances for black spot diseases.
  • Remove infected plant debris: Fungi can overwinter in contaminated plant debris, so remove all fallen leaves from infected plants as soon as possible.
  • Rake and discard fallen leaves in the fall.
  • Prune regularly.
  • Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback. Adding a layer of mulch to the soil will also reduce splashing.
  • Grow plants in an open, sunny locations so the foliage dries quickly.
  • Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation.
  • Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
  3. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
  4. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

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
Insufficient light
China rose thrives in full sunlight but is sensitive to heat. As a plant commonly grown outdoors with abundant sunlight, it may exhibit subtle symptoms of light deficiency when placed in rooms with suboptimal lighting.
View more
(Symptom details and solutions)
Leggy or sparse growth
The spaces between leaves or stems of your china rose 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.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Impact on flowering and fruiting
Your plant may not show obvious abnormalities due to insufficient sunlight, but it can have adverse effects on future flowering and fruiting.
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.
Excessive light
China rose thrives in full sun exposure but is sensitive to heat. Although sunburn symptoms occasionally occur, they are unable to withstand intense sunlight in high-temperature environments.
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.

Essentials
China rose is a plant that requires a temperature range of 41 to 100 ℉ (5 to 38 ℃) for optimal growth. It is native to temperate regions with moderate temperature fluctuations. During different seasons, it is suggested to adjust the temperature accordingly to maintain its growth.
Regional wintering strategies
China rose has strong cold resistance, so special frost protection measures are usually not necessary during winter. However, if the winter temperatures are expected to drop below {Limit_growth_temperature}, it is still important to provide cold protection. This can be achieved by wrapping the trunk and branches with materials such as non-woven fabric or cloth. Before the first freeze in autumn, it is recommended to water the plant abundantly, ensuring the soil remains moist and enters a frozen state. This helps prevent drought and water scarcity for the plant during winter and early spring.
Important Symptoms
Low Temperature
China rose is cold-tolerant and thrives 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}, although there may not be any noticeable changes during winter, the branches may become brittle and dry during springtime, and no new shoots will emerge.
Solutions
In spring, prune away any dead branches that have failed to produce new leaves.
High Temperature
During summer, China rose should be kept below {Suitable_growth_temperature_max}. When the temperature exceeds {Tolerable_growing_temperature_max}, the leaves of the plant may become lighter in color, the tips may become dry and withered, and the plant becomes more susceptible to sunburn.
Solutions
Trim away the sunburned and dried-up parts. Move the plant to a location that provides shade from the midday and afternoon sun, or use a shade cloth to create shade. Water the plant in the morning and evening to keep the soil moist.
