Last night, I fertilized the lawn with IFA Spring/Summer Blend 25-5-10 Premium Lawn Fertilizer. The bag said it would handle 8,000 sq ft, and I believe I have about 5,000 sq ft of sod. I used most of the bag, and took the rest and threw it around my burning bushes, golden rain trees, and around two of the big Autumn Blaze maples. Oh, yeah, I also gave a little to the laurel bushes and to one of the birch trees.
