Broccoli in a Zone 11 season
Zone 11 gives about 365 frost-free days. Broccoli needs roughly 65 days from transplant. That leaves about 300 days of slack, so there is room for a late start or a second planting.
How to grow broccoli
Start seeds indoors about 4 weeks before planting out, timing it so the heads form in cool weather. Cut the central head, then enjoy side shoots for weeks. Heat makes the heads loose and uneven.
