Encore Azaleas come in 31 bloom colors and sizes. They rebloom in spring, summer and fall. Encores thrive best in 4-6 hours of sun or high filtered shade each day for optimum blooms and growth. They tolerate full sun but some shade from the afternoon heat is encouraged. Encores require little pruning, no dead-heading. Be sure to prune immediately after spring flowering. Fertilize after the last frost.
