Azaleas perform best in rich, moisture-retentive, well-draining, acid soils. They require regular watering because of their shallow roots - but do not like being soggy. So an azalea bed should be prepared with humus and raised to provide good drainage. Mulching the shrubs with a 4" - 6" layer of pine needles helps keep even soil moisture. This also provides an added benefit of maintaining an acid environment, since Houston water is alkaline.

Choose a location where they will receive afternoon shade. Fewer flowers are produced if they are kept in total shade. Prune to shape only after they are done blooming in spring, including repeat blooming azaleas. Pruning at other times will remove flower buds. Feed monthly after spring blooming until June with a fertilizer formulated for Azaleas, Camellias, and Magnolias.
