|I am a new gardener, having purchased a house from the previous president of the neighborhood garden club. I'd like to keep it healthy and beautiful. I have a compost bin, have begun the compost process and am eagerly looking forward to "feeding" my garden soil with nutrients. However, the garden is almost all perennials -- full during the spring/summer months. How do I incorporate compost without disturbing the plants? I've read that you spread out 4 inches of compost and till it in 8-10 inches deep, but that doesn't seem to make sense unless you're starting with an "empty" garden. What's the best way?
