Fall planting
Sep 29 – Oct 13UMass Extension's cover-crop fact sheet sets the general rule at about 30 days before the first expected frost date and, in the following sentence, names winter rye as a species that may go in a little closer to that date; the stated 30-day point is taken as the window opening and expanded to the standard 14-day span, with rye's tolerance for later seeding noted rather than quantified, since "a little closer" prints no number. Anchored to the median first fall freeze (Oct 29). UMass Amherst Center for Agriculture, Food, and the Environment
