For maximum bloom power, azaleas need a good amount of sun-at least four to six hours per day. For most of the country, we recommend planting your azaleas in full sun to partial shade. However, these delicate blooms may become burnt in hot sunlight. If you're gardening in Zone 8 or 9, try to site your azaleas in a location that receives afternoon shade. Azaleas can also benefit from a little wind protection, making them perfect plants to place alongside fences.
