Peanuts through the year
Against the frost risk in Banan
Why these dates
Sow direct two weeks after the last frost once the soil is genuinely warm, or start indoors and plant out - peanuts resent root disturbance, so use deep pots. Once the flowers fade, the stalks bend down and push into the soil; anything that stops them reaching loose ground stops the crop.
Frost-tender at both ends of the season. The plant is killed at 0C, and because the pods develop underground over a long period, an early autumn frost catches a crop that is not yet finished.
Seed packets and extension guides express timing as weeks either side of the last spring frost, because that is the only reference point that travels. Peanuts are timed from 4 weeks before that frost for an indoor start, with planting out 2 weeks after it, and this page simply resolves those offsets against the frost date computed for Banan.
The median frost-free season here is 322 days, against 120 to 150 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
