Q: Last fall I transplanted a number of mature azaleas. This past spring I fertilized them with cottonseed meal. How often and when should I use this?
A: Cottonseed meal makes an excellent fertilizer for azaleas because it acts as a mulch while it decomposes and releases nutrients. Each year, put a layer 1/2 inch thick under the plants in early spring and check to see if it’s gone by July. If so, reapply another layer. Cover with pine straw or chips each time.
