Well, I was just tree-mailed by someone stating that working clay soil while it's wet is bad. I'm going to state right now that I've been doing this every year since the spring of 2006 and haven't destroyed my soil yet. So please do speak with someone who's a master gardener in your specific area about how to work the soil in YOUR SPECIFIC AREA. My area in Colorado is heavy clay and that's what is advised in my area: work it as early as possible when the snows melt. If someone waits until it dries out to work, then you're not going to work it at all as it turns into a solid base that is impossible to work by hand. Heavy machinery is required. Trust me, my back knows!!
