Answer: There are several reasons why azaleas might not bloom. Azaleas need morning sun or very bright dappled light all day in order to bloom. In too much shade, they will not set flower buds and their growth will be thin and leggy. They do best in evenly moist yet well drained soil that is acidic and organic. If the soil is too dry, they will not set buds or the buds may dry out. They are not heavy feeders, but do appreciate a slow release granular fertilizer such as Hollytone each spring along with a topdressing of compost and a year round layer of organic mulch such as pine fines over their root area. The mulch should be about two inches deep. Those steps will help provide ample fertility. Finally, azaleas grow on wood that grew the year before. If pruning is needed, do it the spring right after they bloom. Pruning at other times of year will remove flowering wood and/or buds for the coming season. I hope this helps you trouble shoot.
