Melons through the year
Against the frost risk in Brooklyn
Why these dates
Plant out three weeks after last frost, not two. Black plastic mulch or a cloche raises soil temperature enough to make melons viable several hundred kilometres further north than they otherwise would be.
Melons stop growing below 15C and never fully recover. Frost is fatal, but the real limit is cool nights.
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. Melons are timed from 4 weeks before that frost for an indoor start, with planting out 3 weeks after it, and this page simply resolves those offsets against the frost date computed for Brooklyn.
The median frost-free season here is 249 days, against 70 to 90 days to maturity for this crop counted from sowing. That margin is what decides whether a late sowing is worth attempting.
