NOTE: Crepe Myrtle may be referred to as Lagerstroemiaindica in this article, in fact, those are the same plants, Lagerstroemiaindica is the botanical name for Crepe Myrtle.
The crepe myrtle is a small tree native to Asia that has naturalized in the Deep South of the United States. When you travel around some areas of the country, you will see the presence of Lagerstroemia in almost every yard. Though certainly not unique, its common use is a testament to its stunning blossoms, peeling bark, and attractive fall foliage that gives the crepe myrtle an unparalleled all-season interest.

Root rot on your Crepe Myrtle (Lagerstroemiaindica) can be fatal if not treated with care. For this reason, we strongly recommend that you follow our guide to keep your plant alive if the symptoms occur: Root soft and blackened.
Why does my Crepe Myrtle have gray mold spots?
Gray mold spots are a type of fungus that is found a lot in flowers, and spreads quite rapidly. If you notice brown (or gray) spots, it is probably this fungus. Don’t ignore these symptoms, as they may end up killing your plant.
The solution is quite logical when you know the cause of the problem. Most of the time, it is due to overwater of the Lagerstroemiaindica. We advise you to remove the infected parts of the plant, cut off the infected roots and leaves, then repot your plant using sterile potting soil and a clean pot.
Why does my Crepe Myrtle have leaf spots?
We provide you with all the information you need to identify and save your plants if they display signs like leaves that suddenly change color or wilt/droop. This sort of sickness is one of the most aggravating for Crepe Myrtle owners.
Why are my Crepe Myrtle leaves turning yellow?
In the world of horticulture, yellowing leaves are undoubtedly the most common problem. The two main causes of this problem are overwatering and a lack of nutrition.
Reduce your watering frequency when you fear your plants are being overwatered, and follow these steps to determine whether they may be lacking in nutrients:
Here are some signs of yellowing caused by the many deficiencies on the Lagerstroemiaindica in question:
- The first symptom of a magnesium deficiency is yellow patches between leaf veins on elder leaves. The leaf’s core turns yellow while the veins stay green. The edges of the leaf yellow last.
- Iron deficiency also shows as yellowing between leaf veins, but it hits young leaves on plant tops and branch tips first.
- Sulfur shortage first affects the youngest leaves, turning them entirely yellow.
- Insufficient potassium causes the leaf edges to turn brilliant yellow while the interior of the leaf stays green. Older leaves show the symptoms initially, and the leaf edges quickly darken.
- A broad yellowing indicates a nitrogen deficiency. Yellowing starts with older, inner leaves. Yellowing spreads as it advances, eventually touching new leaves as well.
According to the symptoms mentioned above, you just have to act accordingly. You can reduce your watering frequency, or fix a deficiency in Potassium, or Nitrogen, for that, you just have to buy a special soil for your deficiency, a consultant in a gardening store will know perfectly well how to inform you.
Is my Crepe Myrtle sunburned?
It is quite easy to find out if your Crepe Myrtle (Lagerstroemiaindica) has been burned by the sun. Just like on us, your plant will change color in this case, it will start to turn yellow or white.
As we saw above, the leaves of your Crepe Myrtle can also change color if it receives too much water or insufficient light.
However, there is a way to tell if it is sunburn; look at the bottom of the yellow leaves, the ones that have a shaded area closer to the root, if this area stays greener, it is probably sunburned, not something else.
Why are my Crepe Myrtle leaves turning brown?
Most of the time, leaves of a Crepe Myrtle that turn brown is a sign that your plant has been sunburned, it has probably been exposed to too much direct sunlight. Don’t panic, your plant probably won’t die from this, but its growth will take a hit.
Should I leave my Lagerstroemiaindica in direct sunlight?
No! Don’t leave your Lagerstroemiaindica (or Crepe Myrtle) in the sun if it displays the symptoms mentioned above; that’s why it’s in such a bad situation.
As stated in the paragraph above, the cure is straightforward: simply position your plant’s Crepe Myrtle so that it is out of direct sunlight. With proper watering and this method, your plant should quickly come back to life.
Why are my Lagerstroemiaindica leaves drooping or wilting ?
This typically occurs when your Lagerstroemiaindica gets dehydrated. Large plants are more at risk since they naturally require more water than smaller plants.
You may quickly determine if your Lagerstroemiaindica plant needs water by under-weighing its pot; if it seems light, the soil and roots are probably fairly dry and require water.
In order to ensure that the roots of your plant receive the water’s benefits, you must first moisten the soil in the container if it is absolutely dry. One common error is to immediately drown the Crepe Myrtle after a dry period in the belief that it requires a lot of water.
This is true, but the easiest way to end it is to give too much water at once. Instead, you should water the soil properly, returning to a peaceful watering rhythm.
Caring Tips for Lagerstroemiaindica
Water is necessary for your plant to live, but timing and amount of watering must be balanced. Overwatering could have disastrous effects on your own name, as we already mentioned.
Touching the soil will let you know whether your plant needs water or not; if it still feels damp, it’s generally best to wait a few more days.
Always keep temperatures stable
It is also a good idea to keep your Lagerstroemiaindica at a stable temperature (especially if it is kept indoors!). At GreenShack, we generally recommend staying in the 65 and 85 degrees F range. Of course, do not place your Lagerstroemiaindica near a source of hot (or cold) air such as A/C units, radiators or the like.
Keep your Crepe Myrtle Dust-Free
This one concerns indoor plants, just like on your furniture, dust is also deposited on the leaves of your indoor plants, the problem is that it can prevent them from receiving the necessary light, this would slow down (or even stop) the photosynthesis process, and eventually, they would lose their colors.
This would be a true journey into hell for your Crepe Myrtle and would also satisfy the pests.
Take a microfiber cloth and gently massage the plant’s leaves to get rid of the dust. Use a damp cloth to make dust removal easier, but avoid using corrosive materials like rubbing alcohol!
Keep drainage in mind
If you have a tendency to overwater, you need to keep an eye on your drainage, we advise you to opt for a pot with drainage holes if it is not already the case and a saucer.
If your pots don’t already have holes in them, you can add volcanic rocks (or any other pebbles with holes) to the bottom of your pot in the meantime. This will assist in creating a channel and keep the water from pooling there for an extended period of time, protecting the roots from decay.
