I am putting in 5 4x8 ft x 8 in. raised beds for all types of vegetables. The soil on the property I would say is a loam...not much clay or sand.Its very dark, close to black. Haven't had it analyzed. I plan to dig up some of that soil where I am going to put a pond in, and then amend it for optimum vegetable garden use. Any recommendations on what to mix in with it? I guess some sphagnum peat moss would help, but how much and what else? Its going to be 100% organic. I will also be brewing compost tea for application in the beds. Thanks all!
