Azalea Plant Features

In the spring, no other flowering shrub can come close the spectacular beauty of azaleas. These amazing plants practically cover themselves with beautiful clusters of showy flowers in a host of colors. Most azaleas bloom once in the spring, but some varieties will re-bloom once their spring show is over. Then, they'll produce another wave of flowers in the summer and again in the fall. Azaleas prefer a partially shady location and do well under the canopy of taller deciduous trees. The plants will eventually grow 5 feet tall and 5 feet wide so be sure to give them plenty of room to stretch out as they mature. Hardy from zones 6-9.

Azalea Growing Instructions

Most azaleas grow best in partial or light shade, and moist, well-drained soil that has an acidic pH. They don't tolerate drought well, so be sure to plant them in a spot where you can provide them with additional moisture if your area suffers from dry spells. Because azaleas like acidic soil, you may need to use soil amendments such as soil sulfur or aluminum sulfate to keep the leaves a rich, dark green color. 

Azaleas are not recommended for animal or human consumption.
