Season edges differ by task — that's the point of checking six at once. In St. Petersburg the earliest opener starts around September and the last holdout closes after June. A week that fails the paint rules on humidity can still pass seeding, and a frost that ends concrete season leaves sealing untouched until nights slip under 50°F.

If you only open one full check, make it deck staining — St. Petersburg's longest season at 225 workable days.
