Asked August 03, 2015, 2:16 PM EDT

I'm getting ready to roto-till some soil for a vegetable garden and a larger area for a future tree bed. I'm in Cheyenne, and my soil is clayey, with a average pH of 6.5. What, if any, should I mix in while I till to really provide a good base for a garden? For the vegetable garden, I plan on adding 3 to 5 inches of blended topsoil on top of the existing soil.

I would skip the blended topsoil for the vegetable garden, depending where the soil came from you could be adding a lot of unknowns to the garden.  Best to amend your soil with peat moss, tree leaves or clean grass clipping (no herbicides). Do not add manure (horse, cow, sheep etc.,) as this can be full of weed seeds and high in salts, neither is good for a vegetable garden.
