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
- Lettuce, spinach, and arugula: direct-sow in cooling soil and keep the seedbed evenly moist. Lettuce, spinach, and arugula.
- Radishes, carrots, beets, and turnips: sow where the cultivar has enough time before severe cold. Radish, carrot, and beet.
- Kale and collards: direct-sow early or set out transplants. Kale and collard greens.
- Peas: sow for a cool-season crop where the calendar window fits. Pea.
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.
