Whole leaf withering
Whole leaf withering is a harmful condition affecting Japanese maple 'Skeeter's Broom', characterized by leaf desiccation, discoloration, and potential death of affected branches. This guide details the disease's causes, symptoms, and management strategies.
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.
Plant dried up
Plant dried up Plant dried up
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Solutions: The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Scars
Scars Scars
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.

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.

Plant dried up
plant poor
Plant dried up
The entire plant may dry out due to dieback or normal seasonal dormancy.
Symptom Analysis
Symptom Analysis
Your plant has dried out and turned brown. It might be starting to wilt, with no noticeable green around the stems and leaves. Touch the leaves, and they may crinkle under your fingers.
Possible causes of a dried out plant include:
  1. Not enough water. A lack of water will lead to dry plant tissue.
  2. Too much water. Watering too much can lead to root rot which makes the plant struggle to take up water. Rotted, mushy roots are a sign of overeating.
  3. Entering dormancy. As perennial plants enter their resting period known as dormancy, their leaves dry out and may fall off. This happens during decreasing day length.
  4. Exposure to herbicides and other toxic substances. If a plant is hit with a large dose herbicide or other toxic chemical, the plant will turn brown.
  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
  3. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Scars
plant poor
Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
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
Solutions
Each source of scarring requires a different approach to help your plant recover.
  1. Protect the trunk and leaves from physical damage like scrapes.
  2. 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.
  3. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
  4. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
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.
  1. Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
  2. Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
  3. 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.

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.

  5. Too much fertility. An excess of fertilizer can prevent plants from taking up water, leading to drying.
  6. Improper sun exposure. Just like humans, plants can get sunburn by intense, direct light. Plants can also dry out if they don’t receive enough light.
To determine whether the plant is still alive and can be saved, you can:
  1. Bend a stem. If the stem is pliable, the plant is still alive. If the stem breaks, the plant is dead.
  2. Gently scratch the stem with your fingernail for signs of green inside. If your plant is dead, the stem will be brittle and brown throughout.
  3. Cut the stems back a little bit a time for visible green growth. If none of the stems have visible green growth, the plant is dead.
Solutions
Solutions
The solution for a dried out plant depends on the cause, so determine the cause before selecting a treatment method.
  1. Adjust your watering: Stick your finger in the soil near the roots. If it feels bone dry or overly saturated, you need to adjust your watering frequency accordingly.
  2. Prune back dead foliage: Snip off any brown stems and leaves on the plant to make space for new growth. This encourages the roots to send up fresh stems.
  3. Move to a proper environment. This may involve decreasing or increasing sun exposure, depending on the species.
  4. Decrease fertilizer applications. If you have applied too much fertilizer, you can repot plants with fresh potting soil.
  5. Wait. If your plant has dried out as daylight is decreasing, it is entering dormancy. Decrease watering and wait until the plant resumes growth.
Prevention
Prevention
Prevention involves providing your plant with the proper environment.
  1. Provide the proper amount of water. The amount of water depends on a plant’s size, species, and environment. A general rule is to allow soil to dry out between waterings.
  2. Place plants in the proper environment. Provide the proper hours of sun and temperature for your individual plant.
  3. Provide proper fertility. Most plants only need to be fertilized once or twice a year; don’t overapply.
  4. Keep plants free from toxic substances. Keep herbicides and toxic household chemicals away from your plants.

Scars
plant poor
Scars
Any light-colored markings that appear on stems but which do not enlarge or multiply are simply scars that have healed.
Symptom Analysis
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
Solutions
Each source of scarring requires a different approach to help your plant recover.
  1. Protect the trunk and leaves from physical damage like scrapes.
  2. 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.
  3. Stop sunburn by moving your plant away from direct sunlight and making sure it has the water it needs.
  4. Frequent leaf or bud loss may be due to insufficient light or nutrients.
Prevention
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.
  1. Review specific guidelines for your plant, including soil drainage, watering, and fertilizer requirements.
  2. Inspect plants before planting and use sterile pots and fresh potting soil or media to limit transfer of fungi or bacteria.
  3. 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.
