Azalea Growing and Maintenance Tips

Planting: Azaleas prefer partial shade or dappled sun with well-drained, acidic soil. Avoid planting in hot, dry locations with direct afternoon sun or reflected sunlight.  For a formal sheared hedge planting 2 to 3 feet apart is recommended. When a natural hedge is prefered space 3 to 4 feet apart. Click on the "About Us" tab to find planting instructions.

Watering: Avoid over or under watering

Fertilizing: In the spring after the last frost, fertilize with a well-balanced, slow-release fertilizer for acid loving plants.

Pruning: After the flowers finish blooming, you can remove the dead flowers and seed heads and trim the plant.  Avoid trimming after July 1 because it will remove flower buds that would bloom the folowing season. Trimming anywhere along the stem can encourage new growth.
