How long does it take a crepe myrtle to grow full size?

Crepe myrtles are very fast-growing trees! They often grow at a rate of 24 inches or more per year. The typical crepe myrtle tree grows between 15 and 25 feet, so in less than a decade, they have reached full size (anywhere from 5 to 10 years).

The crepe myrtle tree is heat-resistant and drought-tolerant, making it a very easy tree to care for. Their bark is smooth and often light in color. The light brown bark appears as if it is peeling away, giving it a speckled and unique look. The peeling of the bark is known as exfoliating bark because of how it looks. The tree usually blooms with showy pink flowers.

How far from my house should I plant a crepe myrtle?

Since crepe myrtles grow so quickly and can be pretty tall, it’s smart to plant your tree not too close to any structures. While the roots of crepe myrtles aren’t invasive, damage could come from the tree or branches falling during a storm later in life. The flowers can also stain paint when they fall off the tree after blooming. Take these things into consideration when planting a baby crepe myrtle.

The attractive bark is a wonderful addition to the front or back of your home, and the relatively small tree isn’t known to cause much damage. Late spring is when they look the best full of flowers and bright colors!

What about dwarf varieties?

Dwarf varieties of crepe myrtles usually won’t grow beyond four feet tall. Some even smaller varieties only grow about a foot tall, making them perfect for small yards and small spaces. These cute little trees are only a few feet tall and wide and bloom all summer and create leaves in the fall. The brilliant fall color is a wonder to see in the cooler months.

A dwarf variety may be a wonderful choice for apartment complexes and to plant near large shrubs. Their mature size won’t get in the way and you can still enjoy these wildly popular trees.

Can crape myrtles be kept small?

You should prune crepe myrtles periodically to keep any old growth off and to promote new growth throughout the seasons. Crepe myrtles do just fine without pruning, but if you have them in a space where light needs to be let through, pruning is ideal. Overall, very little pruning is required.

Is it crepe myrtle or crape myrtle?

The spelling of crepe/crape is much like color/color and gray/grey, it just depends on where you are from. If you see it spelled crepe myrtle, you are most likely talking to someone from the south. If you see crape myrtle, the person may be from the north. This isn’t always the case, but it seems to be the trend. No one is wrong, so pick the spelling you like and go with it.

Is powdery mildew on my tree bad?

If you notice powdery mildew on your crepe myrtle plants, your tree is most likely infected. You will see these white speckled spots on the leaves, shoots, branches, and bark of the tree. You will even see it on the flower buds. As the mildew takes over, the leaves will start to fall off.

Watch out for root rot as well. While crepe myrtles do well in all soil types, well-drained soil is best for any plant. This will help avoid plant diseases and sooty mold from developing. Plant your tree in full sun to make sure they stay as dry as possible. Use a slow-release fertilizer whenever possible to promote new and future foliage growth. The pine bark will thank you.
