How to Prune Louisiana Azaleas


Azaleas are popular shrubs that usually bloom in the spring. It's not uncommon In southern Louisiana to have some varieties flower for six to eight months of the year. According to Louisiana State University Agricultural Center, azaleas comprise 7 percent of all nursery plants grown in Louisiana. They do best in moist, well-drained soil and partial sun. Prune Louisiana azaleas to improve the shrub's shape and to control its size.

Step 1

Prune Louisiana azaleas when flowering finishes in April or May. Allow the shrub to reach the desired size before attempting to control growth.

Step 2

Look through the Louisiana azalea for the tallest or widest branches. Clip them off with the pruning shears. Make the cut on the inside of the bush so that the new growth will fill in gaps within the shrub's bulk.

Step 3

Remove branches that appear to be broken, weak or diseased. These are stealing nutrients from the rest of the bush. Prune them where they meet healthy wood.

Step 4

Trim branches one by one until the desired shape and size of the Louisiana azalea is accomplished. Focus more on branches in the top half of the bush. Removing them will increase sunlight and air circulation to the rest of the plant.

Step 5

Prune Louisiana azaleas until late June or early July. After that, there is danger of removing flower buds.

Tips and Warnings

  • Don't shear Louisiana azaleas with hedge clippers. This will ruin the natural form of the bush.
