Q.Soil Amendment
I have my vegetable garden spot dug up but not rototilled. I plan to have a truck deliver some compost. How much should I have delivered, and should I add anything else at that time? My garden is about 12 feet by 40 feet. It’s a new garden spot.
I would have my soil tested to see what I needed to add. This is done by your local agricultural extension service. Depending on your soil type, a layer 4-12" of compost could be worked into the area. The depth of compost layer would depend on your soil, compost composition and what "quality" you want your soil to have.
