What to Plant in October in Zone 9

In USDA zone 9, October is a strong cool-season planting month. Sow leafy greens and roots as heat eases. Set out broccoli, cabbage, kale, and collard transplants when the catalog window and local weather agree. Garlic usually waits until cooler late-fall or early-winter soil.

Typical first frost for zone 9 averages around December 10. Confirm your date with the first frost guide and the first-frost lookup. Also check the zone 9 October calendar and what to plant now.

Sow Now

Transplant Now

Broccoli and cabbage transplants can go into prepared beds as heat breaks. Starting them from seed outdoors now may be too slow for the main fall harvest. See broccoli, cabbage, and their fall planting guides.

Wait on Garlic

In zones 9 to 10, garlic usually waits for cooler late November through January soil. Softneck varieties and pre-chilling are common in mild winters. Prepare a well-drained bed now, but wait for cooler soil unless local guidance says otherwise. Garlic timing by zone.

Next Steps

Sow one short row at a time, water until seedlings stand, and keep harvesting remaining warm-season crops until cool weather ends them. Compare October zone 8 and October zone 10.
