Ideal at least 55 portionsWon't grow below 45 portions
Coldest night of the year (average)
Ideal at least -20°F (-29°C)Won't grow below -29°F (-34°C)
Frost-free days
Ideal at least 140 daysWon't grow below 110 days

Yearly rain
Ideal 30–59 in (750–1,500 mm)Won't grow below 18 in (450 mm) or above 98 in (2,500 mm)

Needs acidic soil (pH 4.5–5.5), which climate can't tell us. Shallow roots: irrigate in dry spells.

How this map works

Every 28 km square of land is scored 0–100 against the requirements above, using 1991–2020 monthly climate averages with frost, chill and heat estimated by simulating daily weather. Each square is scored with whichever variety fits it best. “With irrigation” ignores rain shortfalls; “Rain-fed only” counts them.

Climate is only part of it: soil, slope, water and markets decide where a crop is actually farmed. Use this to shortlist places, then check them locally.
