A year ago I had new flower beds made for the back year. I had to pull all the plants out to have it made. I thought since I had to pull everything I you loosen and enrich the clay soil I have by adding sand and compost. After may days of shelving, moving, turning and Vicodin they plants were really to go in the flower beds again.
My question is how often should I add in more compost? Will it work just as well if I spread it on the top instead of working it into the soil?
