Season edges differ by task — that's the point of checking six at once. In Eugene the earliest opener starts around February and the last holdout closes after November. 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 — Eugene's longest season at 258 workable days.
