Yellowing Crepe Myrtle Leaves: Why Are Leaves On Crepe Myrtle Turning Yellow?

The leaves of crepe myrtle (Ceratocrotolara) have been known to turn yellow due to a fungus called Cercosporium sp. The disease causes the leaves to curl up at the tips, which eventually turns them into a wrinkled appearance. There are many theories about what causes the disease, but it’s believed that the fungus produces toxins that cause the disease. The symptoms include wilting of the leaves and a drop in quality of the foliage.

What Causes Yellowing Crepe Myrtle Leaves?

There are several reasons why crepe myrtle leaves turn yellow. One theory is that when sunlight hits these plants, they may not get enough light to photosynthesize properly. Another reason could be that the plant itself is dying from other factors such as drought or excessive watering. If you notice your crepe myrtle leaves turning yellow, then there are things you can do to prevent further damage.

How Can I Prevent My Crepe Myrtle Leaves From Turning Yellow?

If you want to avoid any future problems with crepe myrtle leaves, make sure that your plants receive adequate lighting during the day. They are very sun-loving plants, so if you can give them at least six hours of sunlight every day, then they should do just fine. If your plants are indoors, then there’s nothing you can do except move them to a sunnier spot.

If your plant is turning yellow because it doesn’t have enough sunlight, then don’t over water the plant. This could cause root rot and eventually kill the entire plant. If the plant is wilting and you can see that the soil is dry around the base of the plant, then you should water it. However, don’t over water it or keep watering it if the soil remains soaked.

Examine your plant for any bugs, insects, or other pests that could be destroying the foliage. If you see any type of pests on the plant, you will need to get rid of them immediately.

Finally, if you think the yellowing is due to drought or overwatering, you should let the soil dry out a little and then water it. If the plant has yellow leaves because it doesn’t have enough light, then you can move it to a sunnier location.

Other Reasons For Crepe Myrtle Leaves To Yellow

There are many other reasons why crepe myrtle leaves turn yellow. One of the most common reasons is due to the age of the plant. When crepe myrtle plants get older, they start to produce less chlorophyll, which is what gives the plant its green color. As the chlorophyll depletes from the leaves, they turn yellow. Adding a high nitrogen fertilizer can prevent this problem.

Another reason why your crepe myrtle leaves turn yellow is due to the type of soil you use. If you live in an area that has alkaline soil, the leaves may start turning yellow from the high pH. You can correct this problem by adding an acidic fertilizer to the soil.

If you live in a highly urbanized area, the pollution in the air can also turn the leaves yellow. Adding an anti-static agent to the soil can prevent this problem. You can also plant the crepe myrtle in a pot and place the pot in a room with filtered air.

How To Save A Crepe Myrtle With Yellow Leaves

If your crepe myrtle has yellow leaves but no other symptoms, this could be a secondary problem. For example, if aphids are sucking the life out of the plant, the leaves turn yellow because the plant is being deprived of nutrients and moisture. In cases like this, you will need to get rid of the bugs before the plant recovers. You can also adjust how you water the plant. In other words, you will have to learn how to reverse the problem.

How To Prevent Yellow Leaves On Crepe Myrtle Trees

One of the best ways to prevent crepe myrtle leaves from turning yellow is to make sure that you are attentive to your plants needs. This means always staying on top of any problems that the plant may be having. For example, if you start seeing aphids on the plant, immediately get rid of them before they suck the life out of the plant. This is also the case if you start noticing any other symptoms such as leaf curling or spots.

Another way to prevent crepe myrtle leaves from turning yellow is to make sure that you are always maintaining the correct soil moisture and nutrients. This means always monitoring the soil around the roots and making sure it isn’t dried out or soaked. It also means making sure that the plant is getting the right ratio of nutrients. If you aren’t sure about any of this, then it would be a good idea to hire a professional.
