Do I need to prune my American Lotus?
Far from damaging the plant, regular pruning will actually encourage American Lotus to produce more blooms. There are two primary forms of pruning for American Lotus. The first is deadheading, which is the gardening term for removing spent flower heads once they start to wither. This concentrates the nutrients for the other flowers and allows the plant to flower better. The final process for pruning American Lotus is the removal of yellow and diseased leaves, which increases plant ventilation and light penetration and facilitates plant growth. When nature runs its course, American Lotus will bloom once, produce seed heads, and attempt to reproduce for the rest of the year. But, by consistently removing flower heads before they go to seed, you encourage the plant to continue producing more blooms for a longer flowering time. When the plant starts to wilt during the full, you should cut off the wilted part above the soil as well.

When is the best time to prune my American Lotus?
There are two primary forms of pruning for American Lotus. The first is deadheading, which is the gardening term for removing spent flower heads once they start to wither. This concentrates the nutrients for the other flowers and allows the plant to flower better. The final process for pruning American Lotus is the removal of yellow and diseased leaves, which increases plant ventilation and light penetration and facilitates plant growth. Since American Lotus requires two types of pruning, you’ll be trimming your plants throughout the growing season. Pinching is most effective in the early spring before the plant develops any flower buds. Removal of yellowing or diseased leaves can be done at any time during the growing season. When nature runs its course, American Lotus will bloom once, produce seed heads, and attempt to reproduce for the rest of the year. But, by consistently removing flower heads before they go to seed, you encourage the plant to continue producing more blooms for a longer flowering time. Finally, deadheading takes place as soon as the plants are producing full flower heads. Expect to take off spent blossoms from mid-summer through the first frosts of fall. When the plant starts to wilt during the full, you should cut off the wilted part above the soil as well.

What tools should I prepare for pruning my American Lotus?
American Lotus doesn’t take much special equipment for pruning. A basic pair of scissors or garden shears should do the trick. It’s a good idea to ensure they are clean before use—you can soak them for thirty minutes in a solution of one part bleach diluted in nine parts water. This reduces the risk of spreading disease lingering on contaminated equipment into your flower garden. Some gardeners avoid using tools altogether and merely pinch off the blossoms with their fingertips. That can be a faster technique, but you run a larger risk of bruising the plant stems or accidentally pulling them out of the ground completely.

Are there any instructions for pruning my American Lotus?
Here’s an overview of pruning instructions for American Lotus based on which of the two types you’re completing. By completing these two types of pruning over the lifespan of your American Lotus, you’ll encourage them to produce bigger, better flowers for far longer than the plants would otherwise. It only takes a few minutes to complete each step of the pruning process, and you’ll reap the rewards of your efforts for weeks to come. Deadheading Deadheading is a fast, easy way to refresh your garden by removing old flowers and providing space for new ones to take their place. You can use your fingers to pop off old flower heads as soon as they look tired, although you’re less likely to damage the plant if you use shears instead. When deadheading, make sure you cut well below the flower so that you aren’t left with a long, flowerless stem sticking out in your garden bed. Instead, cut the stem to just above the point where the side stem joins the main plant. Remove yellow and diseased leaves, this increases the ventilation and light penetration of the plant and facilitates its growth. When pruning, the leaves need to be trimmed off together with the petiole. It is best to use sterilised scissors to cut them off. Note: It’s a good idea to ensure scissors or garden shears are clean before use—you can soak them for thirty minutes in a solution of one part bleach diluted in nine parts water. This reduces the risk of spreading disease lingering on contaminated equipment into your flower garden.

Common issues for American Lotus based on 10 million real cases
Leaf wilting
Leaf wilting is a serious disease impacting the overall health of American Lotus. Primarily attributed to fungal infections and unfavorable environmental conditions, the disease severely affects the plant's photosynthesis, leading to premature wilting and eventual plant death if untreated.
Fruit withering
Fruit withering Fruit withering
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Solutions: There are a number of appropriate solutions to control fruit withering: Remove any fruit as soon as it shows any signs of infection. Do not compost. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
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.
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.

Fruit withering
plant poor
Fruit withering
Fungal infection or normal ripening can cause the fruit to dry out.
Overview
Overview
Fruit withering is common on many tree fruits, including apples, pears, peaches, cherries, and plums, as well as fruiting shrubs. It is caused by a fungal pathogen and will result in wrinkled and desiccated fruit.
Symptom Analysis
Symptom Analysis
Here are the most common symptoms in the order that they are likely to occur.
  1. Both leaves and blossom on the tips of branches will go brown and wither.
  2. Gray powdery patches will appear on infected leaves and flowers, and this will be most apparent after rain.
  3. Any fruit that does appear will turn wrinkled and fail to develop.
  4. Branch tips begin to die, progressing back to larger branches, causing general deterioration of the tree or plant.
Disease Cause
Disease Cause
The withering is caused by one of two fungal pathogens, one called Monilina laxa and the other called M. fructigen. The spores overwinter on infected plant material and are then spread the following spring by wind, rain, or animal vectors. The problem will start to become noticeable in mid-spring, but will increase in severity as summer progresses and the fungus grows. If not addressed, the disease will intensify and spread to other plants in the vicinity.

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.

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.

Lighting
Full sun
American Lotus thrives in areas where it receives abundant sunlight throughout the day. With an origin in sun-drenched habitats, it can endure extreme exposure to sunlight without wilting. However, an absence of sufficient sunlight might lead to stunted growth and poor flowering. Excess or deficient sunlight doesn't confer much tolerance.
Best Sunlight Practices
Transplant
2-3 feet
Ideal for relocating american Lotus is the late winter to early spring period (S4-S6), as this coincides with its dormant state, thus reducing stress on the plant. For optimal growth post-transplant, choose sun-filled, wet or water-inundated locations. To promote its adaptation, ensure the root ball remains intact and moist during the process.
Transplant Techniques
Temperature
-30 - 35 ℃
American Lotus is native to areas with temperate climates where the temperature ranges from 32 to 90 °F (0 to 32 °C). This plant prefers a steady climate with minimal temperature fluctuations. Seasonal adjustments may be necessary if severe temperature variations occur.

Smooth hawksbeard
Smooth hawksbeard
The smooth hawksbeard is distributed throughout Africa and the Northern Hemisphere. This Crepis capillaris is most often found alongside roadways, in vacant lots, or other neglected areas. The bright yellow flowers attract certain flies and moths, while the seeds can be a food source for some birds.
Bird lime tree
Bird lime tree
Bird lime tree is a medium-sized tree with sticky fruit. In China, the fruits are pickled with ginger as a delicacy, but in its native setting, insects and even small birds can get caught and trapped on these fruits, giving rise to another of this plant's common names, the Bird catcher tree.
Little ironweed
Little ironweed
Little ironweed (Cyanthillium cinereum) is an annual or perennial wildflower that can grow to 1.2 m tall. It produces purple, button-shaped flowers that consist of numerous flower heads. It can be a common weed that grows fast and can be found growing along roadsides, garden beds and construction sites. It is invasive in tropical and subtropical areas.
Purple dead-nettle
Purple dead-nettle
Purple dead-nettle (Lamium purpureum) is an herbaceous annual weed, commonly found in meadows, wastes, gardens, and at the edges of roads and woodlands. Though it appears similar to true nettles, purple dead-nettle gets its name because it does not have "live" nettle poison that harms the skin. It originated in Asia and prefers environments with full sun.
Common Wireweed
Common Wireweed
Sida acuta is a flowering perennial in the mallow family that is known as common Wireweed. The plant gets its name from its tough, wiry stems and branches. Though common Wireweed is native to Central America and southern North America, this hardy plant has become invasive elsewhere - its wiriness, unfortunately, makes it very difficult to remove from the ground by hand.

Brown spot

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.

Wilting after blooming

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.

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
American Lotus is commonly grown as an aquatic plant, thriving in open and sunlit environments. However, when placed in indoor settings with insufficient light, subtle symptoms of light deficiency may arise, often going unnoticed.

(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your American Lotus 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.
Slower or no new growth
American Lotus 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.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
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
American Lotus thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.

(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
American Lotus is native to areas with temperate climates where the temperature ranges from 32 to 90 °F (0 to 32 °C). This plant prefers a steady climate with minimal temperature fluctuations. Seasonal adjustments may be necessary if severe temperature variations occur.
Regional wintering strategies
American Lotus 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 covering the plant with materials such as soil or straw. 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
Symptoms of Low Temperature in American Lotus
American Lotus 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, there may be a decrease in sprouting or even no sprouting during springtime.
Solutions
In spring, remove any parts that have failed to sprout.
Symptoms of High Temperature in American Lotus
During summer, American Lotus 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, prone to curling, susceptible to sunburn, and in severe cases, the entire plant may wilt and become dry.
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.
