Azalea Care Apply 1 pound of actual nitrogen per thousand square feet of root spread area. Up to 2 pounds can be applied with a slow-release fertilizer. In the absence of a soil test fertilize azaleas lightly in the spring and early summer with a well-balanced, extended-release, acid-forming, azalea fertilizer. By well-balanced, this means to look for nutrients in the ratio of 2-1-1. Good quality azalea fertilizers will also contain necessary trace elements. Never fertilize azaleas in the late fall with these high nitrogen fertilizers, as this may delay dormancy and result in plant injury.

Rhododendrons and Azaleas Established azaleas often do well with no fertilizer at all. Nutrients are slowly released by any organic mulch that you use, so rely on this as the primary source of nutrients. Excess nutrients may promote larger than normal populations of azalea pests like lace bugs and azalea whiteflies.

- In less fertile soils, a complete fertilizer designed for acid-loving plants may be applied in late winter or early spring.

- To determine whether the soil drains well where you want to plant your azalea, dig a hole before it rains, then check back afterward. If the hole is filled with standing water, the soil doesn't drain well; it's likely highly composed of clay. If the water is gone, the soil should be fine for azaleas.
