Crepe Myrtle Diseases Pictures

Crepe myrtles, also known as American or clumping myrtles and, are deciduous trees that are native to the southeastern United States. As an evergreen plant, crepe myrtles are especially prone to disease. That’s why it’s crucial for gardeners and homeowners to take precautionary measures when planting these beautiful trees. Edible Crepes Myrtle Disease is a particular ailment of crepe myrtle that can cause leaves on the plants to turn brown and ultimately die off.

  6. Leaves form a waxy sheath on portions of itself with dead zones underneath.
  7. Leaves curl inward, giving an “orcid” appearance.
  8. Many leaflets on one stem, meaning more than 5 leaflets per stem is considered diseased as well as branches that have more than 15 leaflets is considered diseased as well.
  9. Any crepe myrtle leaves with a “wet look” are likely to die.
  10. Leaves that are wilted or drooping, meaning the leaves hang down without support.
  11. Sunken centers on the its leaves can be a sign of disease as well as discoloration in the middle of the leaf.

Crepe myrtles can eventually die if infected by this disease.

The American crepe myrtle is a deciduous shrub whose scientific name is Lagerstroemia indica and it is native to the southeastern United States. Crepe myrtles are usually medium to large trees. Crepe myrtle are deciduous plants, meaning they go dormant during the winter and wake up in spring once the weather is warm again, their leaves appear in spring. The growth of this crepe myrtle is different than a typical shrub. This plant grows at a slow rate compared to other shrubs, due to its evergreen nature it can take up to 50 years for a tree to grow from seedling to full-size tree.

It commonly have flowers of white, pink, or red. These flowers are what make it an ideal plant for landscaping. Crepe myrtles are used in landscaping because of their ability to grow in a variety of soil types and their hardiness. This plant is especially great for regions that have high heat and drought, as well as low soil acidity. It is also a broad-leaved deciduous shrub with male and female flowers on different trees.

What does a diseased crepe myrtle look like?

Edible crepe myrtle disease was first documented in Houston, Texas. Crepe myrtles have a waxy and tough outer coating to protect themselves from extreme weather. The main pollinators of this tree are bees, not just any bees but the carpenter bees will come and pollinate the tree. The crepe myrtle is also known for their flowers that attract hummingbirds as well as butterflies.

How To Solve Common Crepe Myrtle Problems From Diseases To Pests

What is wrong with my crape myrtle?

Edible crepe myrtle disease can cause loss of leaves, and branches that can lead to the eventual death of the tree. The disease causes dark lines that snake across the leaves, giving them a striped appearance. These stripes appear on both sides of the leaf and eventually cause the leaf to die. This disease is spread by way of insects, specifically carpenter bees. The infected bees go to a healthy crepe myrtle and then pollinate the flowers of that tree. Once the pollination is complete, the bees will then fly to the diseased tree and pollinate it as well. Due to the nature of this disease, it is crucial to remove any dead or dying plants from your garden in order to prevent spreading of this issue.

Why are the leaves on my crepe myrtle curling?

Leaves on this plant begin to curl because the plant affects the chlorophyll in the leaves. Chlorophyll is what gives the leaves their green color, and this disease causes them to lose their color. Without chlorophyll, the leaves turn pale or yellow and eventually die off.

What are these brown spots on my crepe myrtle?

The brown spots are most likely a form of blight disease. The disease is caused by fungi that form under the bark of your trees. These spots can cause your trees to become vulnerable to other infections.

What are these stripes on my crepe myrtle?

The stripes are most likely caused by a plant disease known as leaf spot. The leaf spot is an infectious disease that can cause leaves to die and often spreads fast, due to the nature of crepe myrtles being a shrub.

Once the leaves of the crepe myrtle are infected, it is likely that your tree will experience permanent foliage loss. This disease spreads rapidly, so it is important to make sure that your plants do not come into contact with any diseased plants.

Evidence in controlling disease in garden areas is highly limited and thus any control efforts are largely speculative. Some evidence suggests the presence of ants and their effect on biological control. Ants are oftentimes an indicator that a healthy environment is present and thus other organisms associated with a healthy environment will prosper as well. If ants are present in its natural habitat, they may be helping to prevent disease by eating diseased foliage, thus reducing the likelihood of infection. The benefits that help keep plants healthy are called ecosystem services, and studies have shown that these services can increase overall crop yields as well as reduce the need for pesticides.

Can you overwater a crape myrtle?

These are very drought tolerant plants and can survive lengthy periods of no watering. Watering should be done deeply, allowing the water to sink 2-4 feet into the soil; rather than pouring water on the surface which causes the water to run off, thus driving nutrients away from the plant. Crepe myrtles are highly responsive to fertilizer. They take up nutrients quickly when given inorganic fertilizers but slow down once they reach their maximum absorption level.
