Berries & small fruit
Cranberries are really a 6-state story: Maine, Massachusetts, New Jersey, Wisconsin, Oregon, Washington. Hatched chalk is the early and late shoulder; the solid stretch is peak.
No chalk window in these states — no meaningful market production, so we'd rather say so than invent dates. Each page says where the supply really comes from.
Bogs are flooded and machine-picked, so u-pick is rare — buy at farm stands, harvest festivals, or bagged from October.
It depends where you stand. Cranberries are really a 6-state story: Maine, Massachusetts, New Jersey, Wisconsin, Oregon, Washington. In most growing states the peak lands around October — your own state's row on the board above is the honest answer.
Massachusetts, where the season runs mid-September to mid-November. Long seasons usually mean a big state with more than one growing region inside it.
Pick your state on the what's-in-season board (it remembers you), or jump to your state's row above — each one links to the full cranberry-and-state page.
