What to plant in October in the USA depends entirely on your zone — this page answers it for every band. October is garlic-planting month and cleanup month across most of the USA, and peak fall planting in the hot band. Plant garlic, sow cover crops, harvest before hard frost, and protect what you want to carry into winter.

October planting by region
| Band | Sow outdoors | Start indoors | Plant out | Harvest now |
|---|---|---|---|---|
|
Cold band USDA zones 3-5 |
Cover crops; garlic. | Nothing. | Garlic cloves. | Root crops, brassicas, late greens under cover. |
|
Mild band USDA zones 6-7 |
Spinach, lettuce and hardy greens under cover; cover crops; garlic. | Nothing. | Garlic, overwintering onions. | Fall brassicas, carrots, beets, kale, late peppers. |
|
Hot band USDA zones 8-10 |
Peas, greens, carrots, beets, brassicas — peak fall sowing continues. | Nothing needed. | Brassica and lettuce transplants. | Fall tomatoes, peppers, beans, greens, sweet potatoes. |
When to plant garlic: what extension services say, region by region
Garlic timing is set by when your ground freezes, not by the calendar, which is why land-grant extension services give such different dates. These are the published recommendations, side by side:
| Region | Extension guidance | Source |
|---|---|---|
| Northern Plains (South Dakota) | Two to three weeks after the first frost, or about mid-October; soil around 50°F at four inches deep is ideal | South Dakota State Univ. Extension |
| Midwest (Illinois) | Four to six weeks before the ground freezes, so cloves root before dormancy | Univ. of Illinois Extension |
| New England (New Hampshire) | October at northern sites, November at more southern sites | Univ. of New Hampshire Extension |
| Mid-Atlantic (Maryland) | Mid-to-late October, so cloves grow roots and a few leaves before cold weather | Univ. of Maryland Extension |
| North Carolina (zone 7) | Mid-October to early November | NC State Extension |
| Georgia | Late September through November | Univ. of Georgia Extension |
Both directions carry a risk. South Dakota State says garlic planted too early may be more susceptible to winter damage, and planted too late its roots will not have time to establish (SDSU Extension); Ohio State likewise warns that early planting gives above-ground growth that is vulnerable to winter damage (Ohio State Extension).
Mulch timing is where extension sources genuinely differ, and it tracks winter severity. In the colder north, South Dakota State says to add six to eight inches of straw or leaf mulch once the soil has frozen (SDSU), and New Hampshire likewise says to mulch once the ground is frozen to prevent frost-heaving (UNH). Ohio State and NC State instead mulch straight after planting, with four inches of clean straw (Ohio State) or four to six inches of straw or leaves (NC State). Follow the guidance for the climate closest to yours.
Is it too late to plant fall vegetables in October?
It depends entirely on your band. The method extension services teach is to work backward from your average first frost to find the last sowing date (Iowa State Extension). Virginia Cooperative Extension adds a "fall factor" of about two weeks because cool weather and short days slow growth, and frost-tender crops such as corn, beans, cucumbers, tomatoes and squash must mature two weeks before frost to give a reasonable harvest (Virginia Cooperative Extension, Virginia Cooperative Extension). In the cold band that has usually closed the door on new sowings; in the hot band the season is only starting.
Hot band (zones 8-10): what extension guides list for October
Florida (UF/IFAS): the target planting date for cool-season vegetables in Central Florida is October 15 (UF/IFAS Extension). October transplants that establish easily include arugula, beets, broccoli, Brussels sprouts, cabbage, cauliflower, Chinese cabbage, collards, endive, kale, kohlrabi, lettuce, strawberry and Swiss chard (UF/IFAS Gardening Solutions). Arizona (Univ. of Arizona, Pima County): early in October sow seed or plant starts of vegetables such as arugula, beets, broccoli and carrots, and keep frost cloth ready in case of a sudden freeze warning (Univ. of Arizona Cooperative Extension, Univ. of Arizona Cooperative Extension).
Cover crops: October is already late in the north
Tennessee's extension puts the ideal window for fall cover crops at mid-September through mid-October (Univ. of Tennessee Extension). Farther north the window closes sooner: in a University of Minnesota trial, cereal rye's spring growth was best when seeded by mid-September (Univ. of Minnesota Extension). Vermont notes that winter rye sown as late as the first light frost can still put on enough growth to help protect the soil, if seeded at a high rate (Univ. of Vermont Extension).
Frost protection: what row cover and low tunnels really give
Extension figures vary with fabric weight and source. Maryland lists heavyweight row cover as giving up to 8°F of frost protection (Univ. of Maryland Extension); Colorado State says floating row covers can provide up to 10°F depending on material (Colorado State Univ. Extension). Treat 2-10°F as the realistic range and check the grade printed on the pack. Hardy vegetables tolerate temperatures down to the mid-to-lower 20s°F (Iowa State Extension); under a low tunnel kale will tolerate 20°F or lower (Univ. of Illinois Extension), and spinach and cilantro are the hardiest (Iowa State Extension).
Which vegetables handle fall cold?
Virginia Cooperative Extension lists kale, turnip, mustard, broccoli and cabbage as cool-season crops that grow well during cool fall days and withstand light frosts (Virginia Cooperative Extension). Extension services do not publish a single ranked "easiest winter vegetable" list, so use the hardy crops they name and check days-to-maturity against your first-frost date.
Curing and storing the harvest
- Winter squash (not acorn): cure at 80-85°F and 80-85% relative humidity, then store at 50-55°F (Iowa State Extension, Iowa State Extension)
- Potatoes: cure two weeks at 50-60°F and 85-90% humidity; once cured store at 40°F and 90-95% humidity (Iowa State Extension, Iowa State Extension)
- Onions: cure two to three weeks until the tops and necks are thoroughly dry, then store at 32-40°F and 65-70% humidity (Iowa State Extension, Iowa State Extension)
October garden jobs
- Plant garlic — cloves pointed end up, mulched after the ground chills.
- Sow a cover crop on every bed you are not still using.
- Cure and store winter squash, onions and potatoes properly.
- Drain and store irrigation lines before the first hard freeze.
- Clear diseased foliage; compost only healthy material.
Common October mistakes
- Planting garlic too early, so it makes soft top growth before winter.
- Leaving irrigation lines charged through a freeze.
- Composting blighted tomato and potato foliage.
- Leaving soil bare all winter, which loses nutrients and structure.
- Relying on frost-tender crops to finish after a fall frost — they are killed or injured below 32°F.

Frequently Asked Questions
When should I plant garlic in the USA?
Two to four weeks before your ground freezes — usually late September to October in zones 3-5, October to November in zones 6-7, and November to December in zones 8-10, where it may need pre-chilling.
What is the point of a cover crop?
It holds soil in place, keeps nutrients from leaching away over winter, and adds organic matter when turned in. A bare winter bed loses more than most gardeners expect.
Can I still harvest in October?
Yes. Root crops, brassicas and hardy greens all crop well into October, and row cover typically adds another two to four weeks.
Is it too late to plant fall vegetables in October?
In the cold band, usually yes for new sowings — count back from your first frost using days to maturity plus about two weeks for slower fall growth (Virginia Cooperative Extension). In zones 8-10 October is the main planting month for cool-season crops.
What plants grow well in October?
Cool-season crops such as kale, turnip, mustard, broccoli and cabbage grow well in cool fall weather and withstand light frosts (Virginia Cooperative Extension); garlic goes in now across most of the country.
What should you not plant in the fall?
Extension services do not publish one universal list. What they do agree on: frost-susceptible crops, which are killed or injured below 32°F, should not be relied on to finish (Texas A&M AgriLife Extension), and woody trees and shrubs should not be pruned in fall because new growth will not harden off for winter (Iowa State Extension).
