Vegetable Planting Calendar USA

There is no single US planting calendar, because the country spans growing seasons from under 100 days to year-round. This calendar is organised by climate band instead: find your band from your frost dates, then read across.

SoilCommander Editorial Team

USA vegetable growing guides · Checked against USDA and Cooperative Extension guidance

Every USA growing guide is written and maintained by our editorial team for real US growing conditions, and checked against USDA hardiness and frost-date data and Cooperative Extension growing advice before publication.

Step one: find your band

Band Where Last spring frost First fall frost Frost-free days
Cold band
USDA zones 3-5
Intermountain West, Northern Plains & Upper Midwest, Lower Midwest & Ohio Valley, Northeast & New England mid-May to early June mid-September to mid-October 90-150 frost-free days
Mild band
USDA zones 6-7
Pacific Northwest, Mid-Atlantic & Upper South late March to late April late October to mid-November 180-220 frost-free days
Hot band
USDA zones 8-10
California & Mediterranean coast, Southwest deserts, Deep South & Gulf Coast February to mid-March (frost-free in the far south) late November to December, or none 250-365 frost-free days

Step two: read your year

What to sow outdoors, by month and band
Month Cold band Mild band Hot band
January Nothing outdoors — ground is frozen or saturated. Peas, spinach and broad beans in the mildest spots, under cloches. Peas, carrots, radishes, lettuce, spinach and potatoes (south Texas and Florida).
February Nothing outdoors. Peas, spinach, radish and fava beans as soil becomes workable. Beans, corn, squash and cucumbers in the low desert; carrots, beets and greens everywhere in the band.
March Peas, spinach and radish very late month where soil is workable. Carrots, radish, beets, lettuce, spinach, peas, turnips. Beans, corn, squash, cucumbers and melons; last lettuce and spinach before heat.
April Peas, spinach, radish, carrots, lettuce, onions, potatoes. Beans late month, carrots, beets, chard, succession lettuce. Heat-tolerant beans, southern peas, okra, melons, sweet corn.
May Beans, corn, squash and cucumbers late month once soil hits 60-70F. Cucurbits, beans, corn; succession lettuce and beets. Okra, southern peas, melons, sweet potatoes, heat-tolerant beans.
June Cucurbits once soil is 70F+; succession beans, carrots, lettuce. Succession beans and corn; heat-tolerant lettuce in shade. Okra, southern peas, melons only.
July Succession beans, carrots, beets and fall greens. Fall carrots and beets; succession beans. Little to nothing — maintain irrigation.
August Fall spinach, lettuce, radish, turnips and fast greens. Fall carrots, beets, spinach, lettuce, radish, turnips. Fall greens late month; beans and squash for a fall crop.
September Fast greens, spinach and radish under cover only. Spinach, lettuce, radish, turnips, overwintering greens. Fall greens, carrots, beets, peas, brassicas — the main sowing month.
October Cover crops; garlic. Spinach, lettuce and hardy greens under cover; cover crops; garlic. Peas, greens, carrots, beets, brassicas — peak fall sowing continues.
November Nothing. Broad beans and hardy peas in the mildest spots. Root crops, greens, peas, brassicas.
December Nothing. Nothing outdoors. Peas, greens, root crops.

Starting seed indoors

Crop group Start indoors before last frost Transplant out
Onions, leeks, shallots 10-12 weeks 2-4 weeks before last frost
Peppers and eggplant 8-10 weeks 2 weeks after last frost, nights above 50F
Tomatoes 6-8 weeks 1-2 weeks after last frost
Brassicas 4-6 weeks 2-4 weeks before last frost
Cucurbits 3-4 weeks After last frost, soil above 70F

Soil temperature minimums

Crop group Minimum soil temperature Ideal germination range
Peas, spinach, lettuce 40F 45-70F
Carrots, beets, radish 45F 45-85F
Beans, corn 60F 70-85F
Tomatoes, peppers 60F 70-85F
Squash, cucumbers, melons 70F 70-95F

Soil temperature is the number that actually governs germination, and it lags air temperature by weeks in spring. Measure at seed depth, at the same time each morning, before sowing anything.

Frequently Asked Questions

How do I find my last frost date?

Look up your USDA hardiness zone for your ZIP code, then check your county extension service for local average last spring and first fall frost dates. Local elevation and water bodies shift these by weeks.

Can I use my USDA zone as a planting calendar?

No. Zones measure average winter minimum temperature, not season length. Two places in the same zone can have growing seasons that differ by months. Use the zone to find your frost dates, then plan from those.

What soil temperature do I need before sowing?

About 40F for peas and spinach, 45F for carrots and beets, 60F for beans and tomatoes, and 70F for squash, cucumbers and melons. Below those figures seed rots rather than germinating.

When should I start seeds indoors?

Onions and leeks 10-12 weeks before your last frost, peppers 8-10 weeks, tomatoes 6-8 weeks, brassicas 4-6 weeks and cucurbits 3-4 weeks.
