Spring : Fertilizing Rhododendrons and Azaleas
March is a great time to fertilize any spring flowering plants in your garden, such as rhododendrons and azaleas. We suggest that you feed your rhodos and azaleas 4-5 times between March and July. Use the recommended total amount on the bag but divide by the number of applications and fertilize once per month. With this simple procedure you should enjoy beautiful blooms throughout the growing season.
