Dig down 4 to 6 inches, grab a handful of soil, and squeeze it into a ball. Then try to crumble it between your fingers. If it won't crumble and feels a bit like brownie batter, it's too wet. Wait a few days and try again. If it crumbles easily, it's ready for planting. If the soil slides through your fingers, it's too dry. Soak the soil and let it drain. Plant once it passes the squeeze test.
