I've got generic dirt.
That's my story and I'm sticking to it! Some of it leans toward a little more clay-like in nature, and other areas are more loam-ish. Seems like I've got a lot of different dirt types here. We're in a river canyon, so I'm sure that there are pockets of everything around here. We don't have sand though, at least not that I've seen.
This is only our second year here. The first year during summer, it was horrific. HOT HOT HOT. Last year wasn't nearly as bad, but it got hot. Had a couple of weeks around the 100 degree range, but not every day. No idea what this year will be. We do have a lot of wind though. It almost never stops. Some days it blows us over, and other days, it is a light breeze.
We've got several farm stores in the city, but I don't think I've ever seen anything called sandy loam compost. I'll check again though, just to be sure. I want to start out right! Better yet, maybe I'll just call them and see what they have. Sure beats a drive to the city!
