Crepe Myrtle Care and Maintenance

Crepe myrtles prefer full sun and well-drained soil. They can tolerate a range of soil types, but perform best in slightly acidic to neutral soil.
These conditions allow the tree to grow robustly and produce abundant, vibrant blooms.
While crepe myrtles are tolerant of drought once established, they appreciate regular watering during dry periods.
Newly planted trees should be watered deeply once a week for the first few months. This helps establish a strong root system, which is crucial for the tree’s overall health and vigor.

Fertilizing crepe myrtles provides them with the necessary nutrients they need to produce their spectacular summer blooms.
Pruning should be done in late winter or early spring to maintain the tree’s shape and promote blooming.
This involves removing dead or diseased wood, thinning out crowded branches, and shaping the tree as desired.
However, avoid heavy pruning as it can lead to weak growth and fewer blooms.
Mulching around the base of the tree can help retain soil moisture and suppress weeds. It also helps to protect the tree’s roots from temperature extremes.
A 2-3 inch layer of organic mulch, such as wood chips or shredded bark, is usually sufficient.
