AZALEAS

Azaleas are perhaps Atlanta's most popular shrub.  The springtime blooms of white, red, pink, and purple, combined with the white blooms of dogwoods, send gardeners into a landscaping frenzy.  Azaleas were first cultivated by the Japanese many centuries ago.  Today, there are thousands of hybrids. Azaleas can be grown in the sun or shade. If grown in full sun, consistent watering is a must or the plant will suffer and die. Azaleas are slow growers and do not need a lot of fertilizer. However, regular fertilizations will result in faster growth and more flowers. Fertilize in February through April. Prune azaleas after they finish blooming. If you prune azaleas in late summer or fall, you will be pruning off next springs flowers. Deadheading, or removing dead flowers, is beneficial to increasing next year's flowers.
