Treat and prevent plant diseases.
AI-powered plant doctor helps you diagnose plant problems in seconds.
Mushrooms
Mushroom disease in Candy barrel cactus refers to a fungal infection causing rotting and discoloration of tissues, potentially leading to plant death if untreated. It commonly results from poor cultivation practices and unsuitable environmental conditions.
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.
Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Solutions: Each source of scarring requires a different approach to help your plant recover. Protect the trunk and leaves from physical damage like scrapes. If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Solutions: If the plant is only infected a little, it can sometimes be saved. This mainly applies to houseplants that are grown in pots. Here's what to do. Remove the plant from the pot and gently shake off as much soil as possible. Using pruning tools that have been disinfected, remove any diseased foliage and roots. Be sure the new pot has good drainage holes and wash it with one part bleach and nine parts water to ensure that it is completely clean and sanitized. Dip the plant's roots in fungicide to kill off any remaining fungal spores before potting into the clean growing medium. Only water the plant when the top inch of the soil is dry and never let the plant sit in water. For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.

Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
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
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
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.

Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
Scars form when the plant repairs wounds. They can be the result of people or pets passing by and scraping the plant. Once the underlying issue is resolved, the plant will heal but a scar may remain.
Pests and pathogens can also cause scarring. Insects may attack the plant for a meal, resulting in extensive scarring when a few invaders turn into an infestation. Diseases such as fungus and bacteria can weaken the plant, causing brown spots, mushy areas, or blisters that lead to scars.
Scars occur on stems when a leaf or bud has been lost and the plant has healed. The harder tissue is like a scab that protects a wound.
On other occasions, scars can signal problems from environmental conditions, such as overexposure to sunlight or heat. It might surprise you to know that plants can suffer from sunburn, even desert dwellers like cactus!
Solutions
Each source of scarring requires a different approach to help your plant recover.
- Protect the trunk and leaves from physical damage like scrapes.
- If pests or disease are the cause of scarring, isolate the plant from others to avoid further spread. Some pests can be removed with organic remedies such as a soft cloth and soapy water solution or diluted isopropyl alcohol spray.
- Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
- Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
Preventing some sources of scarring is easier than others, but all start with careful attention to your plants once you decide to bring them home.
- Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
- Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
- Once established, check your plants regularly for signs of scarring or the presence of pests, as it is better to catch problems as early as possible.

Stem rot
Bacterial infection can cause the stems to become soft and rotten.
Overview
Stem rot is a serious disease and can affect many different types of plants. it can be particularly prevalent when the temperature of the soil is over 16 ℃ and there's a lot of moisture in the soil. This could be from unusually heavy rainfalls or too much irrigation. Once stem rot sets in, it's very difficult to get rid of the disease and most affected plants will have to be discarded. This is especially the case for vegetables, herbs, and other herbaceous plants that have soft stems. This is why it's important to ensure that the soil used for growing these plants is well-drained and that overwatering is avoided. Using good cultural practices also help in curbing these types of fungal diseases.
Symptom Analysis
Plants that have been affected by stem rot will first display a yellowing of the lower leaves. This is followed by obvious wilting and stunted growth.
If the stem of the affected plant is examined closely, there will be some dark discolorations starting near the base and moving upward. If the roots of affected plants are examined, they will appear dark and mushy instead of white and healthy-looking. Eventually, the entire plant will wilt and die.
Disease Cause
Stem rot is caused by a variety of soil-borne fungus pathogens. The type of fungus depends on the species of plant that is affected. Two fungi responsible for stem rot are Rhizoctonia and Fusarium. These fungal pathogens live in soil and migrate to the plant when conditions are optimum. This includes warm, humid weather and excessive soil moisture. Commonly, vegetable seedlings are affected by these fungi.
Sclerotinia sclerotiorum is another fungus that causes stem rot in plants. This fungus has a host range of over 350 different species of plants. Plants most susceptible to this fungus include many vegetable varieties such as cucumbers, beans, cilantro, carrots, cabbage, melons, lettuce, peas, onions, tomatoes, pumpkins, and squash. This fungus can produce different symptoms in different species. In some cases, the fungus causes irregular spots on stems and other plant material that appear water-soaked. On other plant species, the fungus appears as dry lesions that grow and girdle the stem of the plant.
The third type of fungus that causes stem rot is Phytophthora capsici. Plants that belong to the cucumber family are most susceptible to this fungal infection. This fungus manifests as water-soaked lesions on the stems that then turn brown and girdle the stem.
All of these fungal pathogens are transmitted to the plant by water splashing from the soil up onto the plant. That's because the fungal spores live in the soil where they wait for the right conditions to infect the plants.

- 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.

For plants that are grown in the ground, it's best just to remove the infected plants and destroy them. Do not plant in the same spot until the soil has been allowed to dry out and has been treated with a fungicide.
Prevention
For outdoor gardens:
- Raking the garden thoroughly in the springtime will help to cut down on pathogens that may be living in the soil.
- Using a copper fungicide on plants in the springtime will cut down on fungal growth and prevent the spread of infection.
- Placing a heavy layer of mulch on top of the soil will also prevent pathogens from splashing up onto the stems of plants.
- Place plants at the recommended spacing to encourage better air flow between them.
- Water plants at the base instead of overhead to prevent excessive moisture on foliage.
For indoor plants:
- Avoid overwatering houseplants and ensure the roots do not sit in water.
- Make sure that indoor plants receive adequate air circulation and light.
