What to plant in October — zone 11a
Zone 11a averages its last spring frost around January 1 and its first fall frost around December 31. Everything below is timed from those two dates, so it stays useful whether you're planting for summer or for a fall harvest.
Dormant care
- Sharpen and oil toolsaround Oct 2
Clean, sharpen and oil blades while there's time — dull tools bruise plants and slow you down.
- Prune dormant fruit treesaround Oct 16
Prune apples, pears and peaches while fully dormant — open the center, remove crossing wood.
Start indoors
- Sow microgreens indoorsaround Oct 9
A tray on the windowsill gives you a cut of fresh greens every 10-14 days through the cold months.
- Start onions and leeks indoorsaround Oct 23
Alliums need 10-12 weeks under lights before they go out — the earliest sowing of the year.
- Onionaround Oct 23
10 weeks of indoor growth before your last frost (01-01). Match day-length to your latitude — long-day north of 37°, short-day south.
- Rosemaryaround Oct 23
10 weeks of indoor growth before your last frost (01-01). In zone 6 and below, grow in a pot and overwinter indoors near a south window.
