Garden vegetables
Across the U.S., sweet potatoes ripen from Hawaii (mid-January) all the way to Arizona (mid-October). 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.
Not a u-pick crop — buy cured roots at fall farm stands, festivals and markets.
It depends where you stand. Across the U.S., sweet potatoes ripen from Hawaii (mid-January) all the way to Arizona (mid-October). In most growing states the peak lands around September — your own state's row on the board above is the honest answer.
Hawaii, where the season runs early January to late December. Long seasons usually mean a big state with more than one growing region inside it.
