Last year, when we removed the sod to create garden beds, we realized that our soil was pretty horrible. It had a high content of sand and clay, and was pretty much void of any good nutrients. So we've been amending the soil a lot by adding in purchased soil, composted manure, peat moss, and our very own homemade compost. We also grew buckwheat as a cover crop in the Fall. Well, this year, as I've been planting seedlings into the garden, I've seen a welcomed sight! Earthworms! Lots and lots of earthworms! When we gardened last year, we saw very little earthworms.
