Against the frost risk in Canoas
Why these dates
Start indoors four weeks before the last frost and plant out two weeks after. Harvest when the skin has turned deep yellow and resists a thumbnail.
Killed at 0C. Harvest before the first frost and cure for a week or two, after which it keeps for several months.
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. Spaghetti squash 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 Canoas.
The median frost-free season here is 330 days, against 90 to 110 days to maturity for this crop counted from planting out. That margin is what decides whether a late sowing is worth attempting.
