Season edges differ by task — that's the point of checking six at once. In Salt Lake City the earliest opener starts around March 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 lawn seeding — Salt Lake City's longest season at 166 workable days.
