Fertilize azaleas lightly using a balanced fertilizer, such as a 10-10-10 ratio fertilizer, or an azalea-specific fertilizer with higher concentrations of nitrogen. It is better to fertilize very lightly two or three times during the spring and summer than to apply the entire year's fertilizer at once.
