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.
Flowers: sweet pea, pansy, snapdragon, and breadseed poppy open October 1. Nasturtium and hardy flowers such as purple coneflower, black-eyed Susan, and columbine open about October 15. See when to plant sweet peas by zone, when to sow poppy seeds by zone, and flower seeds to sow in fall by zone.
Herbs: before nights linger near 50F, pot basil and other tender herbs for a windowsill winter garden. In cold zones, bring rosemary indoors. Hardiness table: which herbs survive winter by zone. Care: rosemary indoors and basil and tender herbs indoors.
Spring bulbs: refrigerate tulips and hyacinths by about Oct 20 and plant them Dec 15 to Jan 5. Jonquil and tazetta daffodils go in now through Nov 30 with no chill. See the Bulb Desk and how to pre-chill tulip bulbs.
Frost and Freeze Protection
Check kill temperatures on the Frost Harvest Desk. See which vegetables survive a hard freeze, how to use row cover and low tunnels, and what temperature kills tomato and pepper plants.
