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

How often should I water my Thimble mammillaria?
There’s not a hard-and-fast rule for how often to water Thimble mammillaria. The best way to determine this is to check the soil and only water when it’s bone dry. You can either stick your finger in the pot or use a moisture meter to check the soil below the surface. When you plant it in a deep pot, you can do this with a stick or chopstick. If it feels even a little bit moist, wait a few days and check it again. Most people will need to water Thimble mammillaria about every two weeks in summer and once a month in winter, but there are several factors that can change the frequency. The section below lists some considerations that can help you to determine how often to water.

What should I consider when watering my Thimble mammillaria?
There are several environmental conditions that will affect how your Thimble mammillaria needs to be watered, including the container size, soil type, temperature, and humidity. First off, the container and soil you use will determine how often to water and how much water to use each time. Be sure you use a container with plenty of drainage holes in the bottom so extra water can escape the pot. A small container has less room for soil, meaning it won’t hold as much moisture, while a larger pot will stay wet longer and need to be watered less often. It’s important not to keep your Thimble mammillaria in an oversized pot as this can easily lead to overwatering. When repotting, move to just one size larger than the current container. A shallow container works better than a deep one, since Thimble mammillaria has shallow root systems. Thimble mammillaria will need to be watered less often in winter and more often in the active growing season in spring and autumn. During the winter, growth slows down considerably and the plant isn’t using much energy or water. There is less water lost to evaporation in cooler winter air, meaning that soil stays wet for much longer than it would in the summer. This also applies to the general climate around your home. If you live in a humid location with a lot of rain, you will need to water less often than if you live in a dry, arid climate. Remember that conditions at the same geographic location can vary significantly with the season and the use of indoor heating and air conditioning. Outdoor Planting If Thimble mammillaria is planted in the ground, after establishing a root system, it shouldn’t need supplemental water beyond what it receives through precipitation and dew. But if there is a long dry period, you may want to water occasionally. In other areas where Thimble mammillaria can only be grown in a container, this plant can be moved outside in the spring and summer when the temperature is proper and then brought back inside when temperatures start to drop. A potted Thimble mammillaria kept outside usually needs more water than the same plant kept indoors, because there is a lot more sun exposure even on a shaded porch.

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

Scars is a physiological disease causing disfigured growth and appearance in Thimble mammillaria. It results from environmental stress, insect damage, or fungal infections, leading to harmful impacts on plant health and aesthetics. Early detection and effective management practices are crucial for control.
Low light
Low light Low light
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Solutions: Low light can only be addressed by increasing light availability, and these measures will only stop further etoliation; current distortion cannot be reversed. Move plant to a position where it receives more light. Check the requirements for specific species, as too much sunlight can cause a plant to burn. Introduce appropriate artificial lighting. Some people choose to prune the longest stems so the plant can concentrate on healthy new growth under the improved lighting.
Fire ants
Fire ants Fire ants
Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all. For less severe cases: Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem). Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes. For severe cases: Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb. Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants. Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.

Low light
plant poor
Low light
A lack of sunlight will cause the stems and leaves to elongate and appear lighter in color.
Overview
Overview
All plants require light, and if they do not receive it in the quantities that they require this distorts their growth in a process known as etiolation. In essence, etiolated plants are diverting all of their energy to growing taller in a desperate attempt to reach a position where they can meet their light requirements. Many other growth factors are harmed by this, and so light-deprived plants can become weak and distorted until they are almost unrecognizable. Low light symptoms are most commonly seen in houseplants, but outdoor specimens can also be affected.
Symptom Analysis
Symptom Analysis
Although symptoms will vary in different plants, the general symptoms of low light are easy to spot.
  1. Plant stems grow tall and lanky.
  2. There are less leaves, and both leaves and stems tend to be pale and insipid looking. This is due to a shortage of chlorophyll.
  3. All plant parts become weakened and may droop, as energy is diverted toward too-fast growth as the plant stretches itself toward any source of light.
Disease Cause
Disease Cause
Plants need sunlight in varying amounts for photosynthesis – a process that produces energy for growth and fruit and flower production. Low light causes a plant to divert all energy to upward (apical) growth in order to find better light. Plant hormones called auxins are transported from the actively-growing tip of the plant downwards, to suppress lateral growth. A drop in cellular pH triggers expansins, nonenzymatic cell wall proteins, to loosen cell walls and allow them to elongate. This elongation results in the abnormal lengthening of stems, especially internodes, or plant "legginess" which is observed in etoliated plants.

Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Overview
Overview
Fire ants are a group of ants that are known for their aggressive behavior and painful stings. Some fire ants are native and others are invasive from other countries. Once they reach plants, they climb them and chew away at leaves and flower buds.
Fire ants also kill and eat beneficial insects such as caterpillars, ladybugs, mantis, and native ants. They can be a problem any time temperatures are above freezing, but new infestations are most likely to appear when brought in via contaminated material such as potting soil or mulch, or when insecticides have harmed populations of beneficial insects that would otherwise control populations of fire ants.
They can be difficult to control, especially once populations become large. Plant damage is typically minor, but fire ants can destroy seedlings.
Symptom Analysis
Symptom Analysis
The number one symptom of fire ants is seeing the ants themselves which are red or black in color. Ant mounds in the ground are also signs. Fire ant mounds rarely exceed 46 cm in diameter. If a fire ant mound is disturbed, many fast-moving, aggressive ants will emerge. These ants will bite and then painfully sting.
Even if no ants are visible, their damage might be apparent. Chewed leaf and flower edges might indicate fire ants. Fully eaten seedlings are another sign.
Solutions

Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy.
Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all.

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.

Temp for Healthy Growth
Propagation
Spring
Thimble mammillaria is a petite, clumping cactus that easily propagates through offshoots, often forming dense clusters. To propagate, gently detach a healthy offshoot and allow the cut end to callous over for a few days to prevent rotting. Once calloused, plant the offset in a well-draining cactus mix, pressing lightly to establish contact with the soil. Water sparingly once the offset is anchored, increasing frequency as tiny roots take hold. Patience is key to ensure successful propagation, keeping the substrate moderately moist but not waterlogged.

Fire ants Fire ants Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Solutions: Caution: fire ants are venomous and cause painful bites which can be fatal in the case of a rare but significant allergy. Fire ants can be a painful pest to have around for you and your plants. Keeping them under control will ensure comfortable gardening for all. For less severe cases: Physically remove mounds. Dig out and remove entire mounds (remember, they go deeper than they seem). Use citrus oil. Pour citrus oil, which is toxic to fire ants, down their holes. For severe cases: Use ant bait. For a chemical solution, broadcast insecticide bait formulated for fire ants in the area around a mound. Apply the bait during a dry evening so the ants can forage for it at night. Look for products that contain Indoxacarb. Release phorid flies. Introduce or promote beneficial phorid flies to gardens. These parasitic flies attack invasive fire ants. Hire a professional. Some ant baits are only available to professional exterminators. For serious cases of fire ants, consider hiring a professional.

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

Fire ants
Fire ants gnaw on the roots of plants and are aggressive toward people.
Overview
Overview
Fire ants are a group of ants that are known for their aggressive behavior and painful stings. Some fire ants are native and others are invasive from other countries. Once they reach plants, they climb them and chew away at leaves and flower buds.
Fire ants also kill and eat beneficial insects such as caterpillars, ladybugs, mantis, and native ants. They can be a problem any time temperatures are above freezing, but new infestations are most likely to appear when brought in via contaminated material such as potting soil or mulch, or when insecticides have harmed populations of beneficial insects that would otherwise control populations of fire ants.
They can be difficult to control, especially once populations become large. Plant damage is typically minor, but fire ants can destroy seedlings.
Symptom Analysis
Symptom Analysis
The number one symptom of fire ants is seeing the ants themselves which are red or black in color. Ant mounds in the ground are also signs. Fire ant mounds rarely exceed 46 cm in diameter. If a fire ant mound is disturbed, many fast-moving, aggressive ants will emerge. These ants will bite and then painfully sting.
Even if no ants are visible, their damage might be apparent. Chewed leaf and flower edges might indicate fire ants. Fully eaten seedlings are another sign.
Solutions

Prevention
Prevention
Fire ants become more difficult to control as they establish themselves, so try to prevent them or treat them early.
  • Monitor new material. Do not bring in any soil or plants from known infested areas, unless if they are "Quarantine Approved." Make sure to check new material for fire ants.
  • Apply insecticide. Some warm and humid areas have high fire ants populations. In these areas, spread a granular fire ants insecticide such as Varsity in the spring near gardens to prevent these unwelcome visitors.
  • Treat early. Spot treat at the first sight of any fire ants mound, as larger mounds are more difficult to treat.

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.
Solutions
Solutions
There are a number of appropriate solutions to control fruit withering:
  1. Remove any fruit as soon as it shows any signs of infection. Do not compost.
  2. Use a fungicide prior to leaf bud and then as per manufacturers instructions throughout the season.
Prevention
Prevention
Preventative measures include:
  1. Ensuring adequate spacing between plants or trees.
  2. Staking plants that are prone to tumbling to prevent moisture or humidity build up.
  3. Prune correctly so that there is adequate air movement and remove any dead or diseased branches that may carry spores.
  4. Practice good plant hygiene by removing fallen material and destroying it as soon as possible.

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
Thimble mammillaria is a beloved choice for indoor gardening, and they require strong light to thrive. However, when placed in rooms with suboptimal lighting, they may develop symptoms of light deficiency.

(Symptom details and solutions)
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 Thimble mammillaria 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
Thimble mammillaria 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
Thimble mammillaria require strong light to thrive, and some are remarkably resilient to sun exposure, rarely suffering from sunburn.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.

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