Crepe myrtles are one of the most popular trees in the southern United States. They are known for their beautiful flowers and for being low-maintenance. However, sometimes crepe myrtles can have problems with their leaves turning brown.
There are several possible causes for this problem. One possibility is that the tree is not getting enough water. Crepe myrtles need to be watered regularly, especially during hot weather.
If the tree is not getting enough water, the leaves will start to turn brown and drop off. Another possibility is that the tree is getting too much water. If the soil around the tree is constantly wet, it can cause the roots to rot and the leaves to turn brown.
Sometimes, crepe myrtle leaves will turn brown because of a fungal disease called powdery mildew. This disease affects the foliage of the tree and makes it look as if it has been dusted with flour. Powdery mildew can be controlled with fungicides, but it is difficult to eradicate completely once it gets started.
Leaves can also turn brown if they are damaged by insects or other pests. Aphids, scale insects, and mites can all cause damage to crepe myrtle leaves. These pests suck nutrients out of the leaves, causing them to turn yellow or brown and eventually drop off.

What Causes Crepe Myrtle Leaves to Turn Brown
It’s common for crepe myrtle leaves to turn brown in late summer or early fall. There are several reasons why this happens, including stress from heat and drought, fungal diseases, and pests.
One of the most common reasons for crepe myrtle leaves to turn brown is stress from the hot summer sun and lack of water.
Crepe myrtles need regular watering (about 1 inch per week) to stay healthy and prevent their leaves from turning brown. If you live in an area with little rainfall, you’ll need to supplement your crepe myrtle’s water needs with irrigation. Another reason for leaf browning can be fungal diseases like powdery mildew or leaf spot.
These diseases thrive in warm, humid conditions and can cause extensive damage to crepe myrtles if left untreated. Fungicides can help control these diseases, but it’s important to apply them early in the season before the fungi take hold. Pests like aphids, scale insects, and mites can also cause crepe myrtle leaves to turn brown by sucking out the plant’s nutrients or injecting toxins into the leaves.
Crepe Myrtle Leaves Turning Brown in Summer
If you have crepe myrtles in your yard, you may have noticed that their leaves are turning brown. This is a common issue during summer, when the weather is hot and dry. There are several reasons why this happens, and there are some things you can do to prevent it.
The first reason crepe myrtle leaves turn brown is because of heat stress. When the temperature gets too high, the leaves can’t transpire enough water to stay cool. This causes them to turn brown and eventually fall off.
Another reason for leaf browning is drought stress. If your crepe myrtles aren’t getting enough water, they will also start to lose their leaves. Make sure you’re watering them deeply and regularly during summer months.
Finally, another cause of leaf browning is nutrient deficiency. If your soil lacks certain nutrients, the crepe myrtles may not be able to get what they need from it. You can have your soil tested to see if it needs any amendments.
There are a few things you can do to prevent leaf browning on your crepe myrtles. First, make sure they’re planted in an area that gets plenty of sun but isn’t too hot or exposed to windy conditions. Second, water them deeply and regularly during summer months.
And finally, fertilize them with a good quality fertilizer formulated forcrepe myrtles . following these tips should help keep your crepe myrtle’s leaves healthy all season long!
Signs of Overwatering Crepe Myrtle
Crepe myrtles are a beautiful, drought tolerant plant that is popular in the southern United States. However, they can be susceptible to overwatering. Symptoms of overwatering include leaves that are yellow or brown, wilting, and branches that die back.
The best way to avoid overwatering crepe myrtles is to water them deeply but infrequently.
Crepe Myrtle Leaves Curling And Turning Brown
Crepe myrtles are a common sight in many Southern gardens, and they are beloved for their showy blooms and ease of care. However, sometimes crepe myrtle leaves will start to curl and turn brown. This can be caused by several different things, so it’s important to diagnose the problem before taking corrective action.
One common cause of leaf curling on crepe myrtles is aphids. Aphids are tiny sucking insects that feed on plant sap. They can cause leaves to curl and distort as they feed.
Aphids also produce a sticky substance called honeydew, which can promote the growth of sooty mold on the leaves. If you suspect aphids are the problem, look for small green or black insects clustered on the undersides of the leaves. You can often blast them off with a strong stream of water from the garden hose.
Another possible culprit is drought stress. Crepe myrtles need regular watering during dry weather to stay healthy and avoid leaf stress. If your crepe myrtle hasn’t been getting enough water, its leaves may start to curl and turn brown at the edges as a defensive mechanism to prevent further water loss.
To correct this problem, simply give your crepe myrtle a good soaking with the garden hose about once per week during dry periods. If you have ruled out both aphids and drought stress, another possibility is herbicide damage from chemicals that were applied nearby (either intentionally or accidentally).
Crepe Myrtle Leaves Turning Yellow in Summer
If your crepe myrtle’s leaves are turning yellow in the summer, it’s likely due to a nutrient deficiency. Crepe myrtles are heavy feeders and require regular fertilization to maintain their vigor. A lack of nitrogen is the most common reason for yellowing leaves on crepe myrtles.
You can correct this problem by applying a fertilizer with a high nitrogen content. Be sure to follow the manufacturer’s directions carefully, as too much nitrogen can damage your plant. If you’re not sure what kind of fertilizer to use, ask your local nursery or garden center for advice.
What Causes Brown Leaves on Crepe Myrtle?
Brown leaves on crepe myrtle can be caused by a few different things. One possibility is that the tree is not getting enough water. This could be due to drought conditions or simply because the tree is not being watered enough.
Another possibility is that the tree is suffering from a nutrient deficiency, which can cause the leaves to turn brown and eventually drop off. Finally, brown leaves can also be caused by pests or diseases, which may attack the leaves directly or cause stress that leads to leaf browning.
How Can You Tell If a Crape Myrtle is Overwatered?
If you think your crape myrtle is overwatered, look for these signs: wilting leaves, yellowing leaves, leaf drop, and stunted growth. These are all symptoms of a plant that is not getting enough water. If you see any of these signs, reduce watering until the plant recovers.
What is Killing My Crepe Myrtles?
Crepe myrtles are one of the most popular landscaping trees in the Southern United States, but they can be susceptible to a number of problems that can kill them. Here are some of the most common causes of death in crepe myrtle trees:
1. Crepe Myrtle Bark Scale – This tiny insect feeds on the sap of crepe myrtle trees, and can cause extensive damage or even death if left unchecked.
The best way to control bark scale is to regularly inspect your trees for signs of infestation and treat with an appropriate insecticide as soon as possible. 2. Canker Diseases – There are several different types of fungal diseases that can cause cankers on crepe myrtles, which can eventually lead to tree death if left untreated. These diseases are often spread by pruning tools that have not been properly sanitized, so it’s important to always disinfect your tools before using them on your crepe myrtles.
Suspected cases of canker disease should be treated with a fungicide according to label directions. 3. Powdery Mildew – Powdery mildew is another type of fungal disease that can affect crepe myrtles, and is characterized by a white or gray powdery growth on the leaves and stems of affected plants. This disease is often more prevalent in humid climates, so regular watering and good air circulation around your trees will help reduce the risk of powdery mildew infection.
If you do notice any symptoms of powdery mildew, treatment with a fungicide according to label directions is recommended. 4. Bacterial Leaf Spot – Bacterial leaf spot is another potentially deadly bacterial disease that affects crepe myrtles. This disease manifests as small black or brown spots on the leaves which eventually turn yellow and drop off prematurely.
Once again, proper watering and air circulation will help reduce the risk of infection, but if you do notice any symptoms then treatment with a bactericide according to label directions is advised. 5 . Root Rot – Root rot is caused by various soil-borne fungi and bacteria, and usually occurs whencrepe myrtle roots are constantly wet or waterlogged due to excessive irrigation or poor drainage conditions .
This condition will slowly kill affected trees over time unless corrective action is taken , so it’s importantto address any drainage issues in your landscape as soon as possible .
