Kalettes in Zone 11a & 11b
Brassica oleracea
When to plant kalettes in zone 11b
Zones 11a and 11b share the same average frost dates in our data, so this page covers both.
Method: Start indoors: Start indoors from seed, then transplant outside. Kalettes needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Nov 20–Nov 27 |
|---|---|
| Direct sow / transplant outside | Dec 18–Dec 25 |
| Estimated harvest | Mar 28 '27–Apr 4 '27 (~100 days after transplanting) |
Spacing: 1 per square foot (square-foot-gardening spacing). Mature height: 2-3 ft.
Kalettes is a trademarked cross between kale and Brussels sprouts, grown for small, frilly-leaved florets that look nothing like the tight round sprouts of its Brussels parent, with a milder, sweeter flavor to match.
How kalettes fits zone 11's season
Zone 11b is frost-free in this dataset, so frost is not what limits the calendar here. What you can plant, and when, comes down to summer heat and daylength instead.
