Whole leaf withering
Whole leaf withering is a critical condition in Japanese maple 'Winter Flame' causing widespread foliage desiccation, discoloration, and potential plant fatality, significantly affecting its ornamental value.
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.
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.
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.

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!

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.

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.

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

Basic Care Guide
Common Pests & Diseases
Transplant
6-8 feet
For japanese maple 'Winter Flame', the zenith of transplanting is best met in the gentle embrace of post-frost spring or the cool caress of early autumn, safeguarding the roots' establishment.

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.
