Azaleas are the major ornamental plants in Louisiana’s residential and commercial landscapes. They are available in a tremendous number of flower colors, growth habits and foliage characteristics. This infograph includes information on planting and maintenance, and pest control recommendations.
The most common azaleas grown in Louisiana landscapes are Indian azaleas.
Planting and Bed Preparation
Provide a loose, very well-drained soil. Most soil in Louisiana are clay based, so you should add something like pine bark. You should also raise the bed 4 to 6 inches.
Fertilize azaleas in late winter/early spring with an azalea-camellia fertilizer or a general use ornamental slow-release fertilizer.
Mulching, Watering and Pruning
Azaleas are a shallow-rooted plant and may need mulching to conserve soil moisture. It's best to water infrequently and deeply than to water frequently and shallowly. Pruning should be after flowering in early spring.
Disease and Insects
Watching insects and disease are necessary for beautiful azaleas.
Too much shade can result in skipped or significantly reduced bloom cycles.
