Cabbages through the year
Against the frost risk in Jakarta
Why these dates
Spring cabbage sown in late summer and overwintered gives the earliest crop of the year. Summer and autumn types go in from an early indoor sowing.
Hardy to about -8C, and savoy types considerably lower. Young transplants handle frost far better than most gardeners expect.
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. Cabbages are timed from 8 weeks before that frost for an indoor start, with planting out 3 weeks before it, and this page simply resolves those offsets against the frost date computed for Jakarta.
