Azaleas require five things to produce abundant blooms in the spring: 1. Be sure the plant receives 5-6 hours of sunlight a day during the growing season. 2. After the plant blooms, add a balanced fertilizer to ensure good growth for next year's flowers. 3. Be sure to deadhead blooms each year to encourage the plant to store energy into the roots. 4. Add a heavy layer of mulch before winter to protect the plant from frosts and help retain moisture. 5. Protect the plants during harsh winters with extra layers of protection with frost cloths or straw bales.
