Using Steer Manure Compost
I'm setting my garden up in 4'x 4'x 7" raised beds. Each bed needs 8 cubic feet of soil to fill it. (Or so the box says that they come in.) My question is, how much steer manure compost does each box need? And if I'm using Miracle Grow Garden soil, does it even need it? And finally, I have read on other sites that it is best to work compost into the soil in the fall, should I do that with the raised beds as well? The compost I have is the prepackaged stuff that I purchased at the nursery if that makes a difference. Thanks so much for your help.
