What to Plant in January USA
On this page
What to plant in January in the USA depends entirely on your zone — this page answers it for every band. In January most of the USA is planning rather than planting. Cold-band gardeners start onions and leeks indoors; mild-band gardeners sow peas and hardy greens under cover; hot-band gardeners in the low desert and the Gulf South are direct sowing peas, greens and potatoes outdoors.
January planting by region
| Band | Sow outdoors | Start indoors | Plant out | Harvest now |
|---|---|---|---|---|
|
Cold band USDA zones 3-5 |
Nothing outdoors — ground is frozen or saturated. | Onions, leeks and shallots from seed; celery late month. | None. | Stored roots, squash and overwintered kale under cover. |
|
Mild band USDA zones 6-7 |
Peas, spinach and broad beans in the mildest spots, under cloches. | Onions, leeks; start brassicas late month. | None — wait for the soil to warm. | Overwintered kale, leeks, parsnips and winter brassicas. |
|
Hot band USDA zones 8-10 |
Peas, carrots, radishes, lettuce, spinach and potatoes (south Texas and Florida). | Tomatoes and peppers for an early spring crop. | Onion sets, brassica transplants. | Citrus, winter greens, brassicas, root crops. |
January garden jobs
- Order seed early — short-season and heat-tolerant cultivars sell out first.
- Check your first and last frost dates before planning anything else.
- Test and label seed-starting equipment before you need it.
- Clean and sanitise trays and pots to reduce damping-off.
- Review last season's notes and write this year's rotation.
Common January mistakes
- Starting tomatoes indoors in January in the cold band — they become leggy and root-bound long before it is safe to plant out.
- Buying seed by zone alone; hardiness zones describe winter cold, not the length of your growing season.
- Working saturated soil, which destroys structure for the whole season.
- Skipping a germination test on seed more than three years old.

Frequently Asked Questions
What can I plant in January in the USA?
It depends entirely on your band. In USDA zones 8-10 you can direct sow peas, carrots, radishes, lettuce, spinach and potatoes outdoors. In zones 6-7, sow peas and hardy greens under cloches. In zones 3-5, January is for starting onions and leeks indoors, not outdoor sowing.
Is January too early to start tomato seeds?
In zones 3-7, yes. Tomatoes want to go outdoors 6-8 weeks after sowing and only once nights hold above 50°F, so a January sowing leaves them stuck indoors for months. In zones 9-10 a January sowing for an early spring crop is normal.
Which seeds should be started first?
Onions, leeks and shallots. They are slow from seed and tolerate a long indoor period better than fruiting crops.
