Article: Fertilizing after pruning is recommended because it provides a needed dose of nutrients to the plant and helps it get ready for the upcoming growing season. Once you clear away the pruned stems and leaves, try to fertilize that same day, or within a couple of days. You can trace the ring into the soil with a stick or with your finger. Keep the edges of the ring 6 inches (15cm) away from the base of the plant. This will serve as a placement guide for the fertilizer. Don't worry if a few grains end up inside or outside the ring. You do not have to get it directly into the groove formed by the stick or your finger. If you can't get a 10-30-10 granular fertilizer, a rhododendron or evergreen fertilizer will do just fine. This means that if you were to dig down 8 inches (20cm), the soil will be wet. If you do not water the plant deeply, then the fertilizer may damage the roots and kill it. How much water you use depends on how dry your soil is and how fast it absorbs water.
