Growing bok choy in zone 10

Bok choy bolts at the first sign of stress in spring, so fall sowings are usually more reliable. Harvest whole heads or pull outer stalks; baby bok choy is ready in a month.

Zone 10 covers south Florida, coastal Southern California, low desert — frost is rare — the calendar flips, with the main garden running fall through spring. Zone dates are medians: frost timing varies within a zone with elevation and terrain, so treat these windows as a solid default and refine them with your own city’s dates below.

Make it local

These windows use zone 10's typical frost dates (last frost ~Jan 25, first frost ~Dec 20). For windows computed from your frost dates, run the ZIP code frost lookup and open the planting calendar — it remembers your city. The seed starting scheduler turns the whole seed rack into one printable, date-sorted list.
