We use mushroom soil every year in the fall. When we do our cleanup/cutback our perennials we add 2 inches of mushroom soil to the whole garden. Acts as a fall mulch and it will break down for use by the plants the next year. We can buy it in bulk but they also sell it in bags. I don't really worry about drainge, if its wet you need to use perennials that love that type of soil. I'm telling you that our gardens bloom longer and bigger than anyone else's. Oh yeah, our name is Perennial Gardens. My old boss turned me onto the soil.
