Leaf blotch
Leaf blotch is a fungal infection impacting the foliage of Wintercreeper 'Silver Queen', causing discolored patches that may lead to premature leaf drop and reduced plant vigor.
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.
Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Solutions: The solution to leaf scorch will depend on the cause, however, in general all cultural care methods that improve plant health and root functionality will reduce symptoms. Mulching the root zone (preferably with wood chip mulch) helps retain moisture, reduce evaporation, and promotes a healthy, functional root environment that is critical for water movement to the leaves. Check the root collar for girdling or circling roots that strangle the trunk and limit water and nutrient movement. Protect trees from severe root damage of nearby construction and excavation. If fertilizer burn is to blame, irrigate the soil deeply to flush out excess fertilizer salts. However, keep in mind that fertilizer runoff is an environmental pollutant. Avoiding excess fertilization in the first place is the best approach. If soil testing has revealed a potassium deficiency, apply a potassium fertilizer and water well. Even if you have enough potassium in the soil, plants will not be able to take it up if the soil is consistently too dry. Severely affected twigs may be removed using a pair of sharp and sanitized pruning shears, as weakened branches are susceptible to secondary infections. If your plant has bacterial leaf scorch, there is no cure. Antibiotic injections applied by a professional can reduce symptoms for a season, however, the above cultural management methods are the best options to reduce symptoms and prolong life. An infected plant will likely die within ten years.
Leaf deformity
Leaf deformities can have a variety of causes.
Solutions: Follow these steps to revive plants with abnormal leaves. Remove damaged leaves: Plants can recover from damage when given the time to do so. Remove any deformed leaves so they don't continue drawing energy from the plant. This also creates room for healthier ones to grow. Stop using herbicide: Though herbicide damage is challenging to diagnose, gardeners can potentially prevent deformed leaves by not using any and by strictly following manufacturers instructions. Spray insecticide: Prevent pests from inhabiting plant leaves by spraying with insecticide regularly and practicing good natural pest prevention techniques. Apply a balanced fertilizer: Solve nutrient deficiencies and excesses by using a well-balanced fertilizer (organic or conventional both work) before planting, and consider topdressing when signs of stress are apparent. Fix watering schedule: If plant leaves are curled downward due to too much or too little water, adjust the watering schedule so the soil is moist, but not damp. Remove infected plants: If the plant has succumbed to a viral infection, not much can be done to revive it. Remove and destroy all compromised plant material to prevent spread to other plants.

Brown spot
This infection can cause brown spots or patches to appear on the plant.
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
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
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.

Leaf scorch
Leaf blight causes leaves to dry out and turn brown starting at their tips.
Overview
Leaf scorch refers to two general conditions: physiological leaf scorch and bacterial leaf scorch. It causes leaves to discolor starting along the margins, and eventually die.
Leaf scorch development is most common in the hot, dry season, becoming most noticeable in late summer. However, it can occur at other times of the year. It most often affects young trees and shrubs, but it can also affect flowers, vegetables, and other plants.
Leaf scorch can get progressively worse over multiple seasons. If the root causes are not addressed, leaf scorch can lead to plant death.
While you cannot reverse the damage caused by physiological leaf scorch, you can prevent further damage. With proper management, plants will fully recover. However, there is no cure for bacterial leaf scorch, which is a systemic infection.
Symptom Analysis
Yellow, brown, or blackened leaves starting with the leaf margins
Dying twig tips on trees and shrubs as leaves die and fall
Often there is a bright yellow border line between the dead and living leaf tissue
Disease Cause
There are numerous contributing causes of leaf scorch.
Bacterial leaf scorch is caused by the bacterium Xylella fastidiosa. The bacteria block the xylem vessels, preventing water movement. Symptoms may vary across species.
Physiological leaf scorch most commonly occurs when a plant cannot take up enough water. Numerous conditions can lead to this issue, particularly an unhealthy root system. Some causes of an unhealthy root system include overly-compacted soil, recent tillage, root compaction and severing due to pavement or other construction, drought, and overly-saturated soils.
Potassium deficiency can contribute to leaf scorch. Since plants need potassium to move water, they cannot properly move water when there is a lack of potassium.
Too much fertilizer can also cause leaf scorch symptoms. The accumulation of salts (including nutrient salts from fertilizers, as well as salt water) accumulate at the leaf margins and may build up to concentrations that burn the tissues.

Leaf deformity
Leaf deformities can have a variety of causes.
Overview
Leaf deformity manifests in the form of curled, cupped, or distorted leaves, often first seen in the spring. There are a number of different possibilities as to the cause and it will not always be easy to isolate the problem without laboratory analysis. In the majority of cases, however, the gardener should be able to isolate the cause through close examination of the plant and the local conditions.
Symptom Analysis
The plant has developed abnormal leaves. They may look similar to leaf curl, but show other problems such as:
stunting
abnormal shapes
a bumpy texture
gaps between leaf sections
raised growths on the top surface
Disease Cause
The causes are widespread and varied and the gardener will need to examine plants carefully as well as consider environmental factors.
Disease due to insect damage: Mites, aphids, and other insects that feast on plant leaves can leave them vulnerable to viral and bacterial disease. Some, like leaf galls and rust, produce distorted leaves. If the gardener sees insects on the plants, it is likely the insect is the culprit. Some mites are too small to see, and laboratory analysis may be required.
Herbicide exposure: Herbicides can stress plant leaves. This may lead to stunted growth and a curling, cupped appearance. Even if the plant owner didn't apply herbicides, herbicide drift and planting in contaminated soils can expose plants to these chemicals. If all plants in an area have deformed leaves, the cause is likely herbicides. Herbicide exposure is also characterized by narrow new leaves.
Less than ideal growing conditions: If plants are exposed to cold temperatures right as their leaves are coming out of the bud, they might become stunted and malformed. If deformed leaves occur right after a cold spell or frost, this is likely the cause. Too much and too little water can also cause deformed leaves. Leaves curling down but not distorting is more likely to be a watering issue than a leaf deformity.
Nutrient deficiencies: A lack of critical nutrients during the growing phase, including boron, calcium, and molybdenum, may lead plant leaves to grow stunted or disfigured. If a nutrient deficiency is to blame, the leaves will also show discoloring.
Fungal infections: a variety of fungal pathogens can distort leaves, as is the case with Peach leaf curl.

Prevention
Physiological leaf scorch is best avoided by making sure your plants have a healthy, functional root system and access to enough water. Water regularly, especially on the mornings of excessively hot, sunny days. Deep, infrequent irrigation is better than shallow, frequent irrigation.
Have your soil tested and apply the proper nutrients. Be sure to not over-apply fertilizers.
Make sure your plants’ roots have room to expand. Avoid compacted soil as well and avoid paving areas above the root zone. Do not till or disturb the soil where plant roots are growing.
Plant new trees and shrubs in the fall, so that they have the maximum amount of time to become established before the environmental stresses of the next summer.
Remove any dead or dying plant tissue that may harbor secondary infections.

Fungal infections: a variety of fungal pathogens can distort leaves, as is the case with Peach leaf curl.
Solutions
Follow these steps to revive plants with abnormal leaves.
Remove damaged leaves: Plants can recover from damage when given the time to do so. Remove any deformed leaves so they don't continue drawing energy from the plant. This also creates room for healthier ones to grow.
Stop using herbicide: Though herbicide damage is challenging to diagnose, gardeners can potentially prevent deformed leaves by not using any and by strictly following manufacturers instructions.
Spray insecticide: Prevent pests from inhabiting plant leaves by spraying with insecticide regularly and practicing good natural pest prevention techniques.
Apply a balanced fertilizer: Solve nutrient deficiencies and excesses by using a well-balanced fertilizer (organic or conventional both work) before planting, and consider topdressing when signs of stress are apparent.
Fix watering schedule: If plant leaves are curled downward due to too much or too little water, adjust the watering schedule so the soil is moist, but not damp.
Remove infected plants: If the plant has succumbed to a viral infection, not much can be done to revive it. Remove and destroy all compromised plant material to prevent spread to other plants.
Prevention
Fertilize properly. Keep your plants full of essential nutrients with a balanced fertilizer.
Regularly monitor for pests. Remove all pests by hand or treat them with an insecticide. Early discovery and treatment will prevent the spread of pests and diseases.
Provide the proper amount of water. Water until the soil is moist, but not damp. Only once the soil dries out, should the plant be watered again.
Protect plants from cold. Bring plants indoors or protect them with frost cloth when bad weather is forecast.
Avoid herbicide exposure. If the gardener or surrounding neighbors are applying herbicides, consider moving vulnerable plants to where they are less exposed to any chemicals that may be carried on the wind.
