When to plant stock 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. Stock needs a head start most zones can't give it by direct-sowing alone.
| Start indoors | Nov 20–Nov 27 |
|---|---|
| Direct sow / transplant outside | Jan 1–Jan 8 |
| Estimated bloom | Mar 22–Mar 29 (~80 days after transplanting) |
Spacing: 2 per square foot (square-foot-gardening spacing). Mature height: 2-2.5 ft.
Stock produces dense, fragrant flower spikes in a wide color range, prized as a cut flower for both the look and the scent. It's a member of the brassica family, related to cabbage and broccoli, which shows up in the pests it has to deal with more than in its appearance.
How stock 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.
