Growing pumpkins in zone 10
For jack-o’-lanterns by October, sow in late May to early June in most zones — check the days-to-maturity on your variety and count back from when you want them. Give vines serious room or grow small-fruited types on a trellis.
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.

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.
