Fall Vegetables to Plant

Written & researched by Elena Marsh Gardening & Landscaping Editor

Updated July 2026

The best fall vegetables to plant are cool-season crops that mature in cooling weather and often sweeten after frost — kale, spinach, lettuce, radishes, carrots, broccoli, Brussels sprouts, garlic, beets and Swiss chard. Most are sown in mid to late summer (July through September) so they finish before hard frost, and the timing is set by counting back from your first fall frost date. Fall gardening extends the harvest for months, faces fewer pests than summer, and produces some of the sweetest greens and roots of the year.

Many gardeners stop after the summer crops, but the fall garden is arguably easier: cooling weather, fewer bugs, and crops that actually improve with a touch of frost. Here is what to plant, and how to time it precisely for your climate.

The count-back method for fall timing

Fall timing runs in reverse of spring: instead of counting forward from the last frost, you count backward from the first fall frost. Because days shorten and growth slows in autumn, add a buffer.

1. Find your average first fall frost date for your area.
2. Take the crop's days-to-maturity from the seed packet.
3. Add about 14 days as a "fall factor" for slowing growth.
4. Count back from the frost date to get your latest safe sowing date.

For example, a 60-day broccoli with a first frost of October 15 should be started by about August 1. Frost-hardy crops can be pushed later because they keep growing (slowly) and even survive past frost.

Frost-hardy crops that sweeten in the cold

These are the stars of fall gardening — cold actually improves them, as plants convert starches to sugars as antifreeze.

Kale and spinach are the most beginner-friendly; carrots left in the ground under mulch become candy-sweet after several frosts.

Semi-hardy crops for early fall

These take a light frost but not a hard freeze, so they suit early-fall harvests and warmer zones.

• Lettuce (leaf types especially) — fast and forgiving; see when to plant lettuce.
• Broccoli — often better in fall than spring; see how to grow broccoli.
• Beets, Swiss chard, cabbage, cauliflower, turnips — reliable cool-season producers.
• Arugula and Asian greens — fast, peppery, ideal for succession sowing.

Fast crops for a September sowing

If summer got away from you, these mature quickly enough to sow in late summer or early fall and still harvest.

Garlic and overwintering crops

Some fall plantings are not for fall harvest at all — they overwinter for the following season. Garlic is the classic: plant cloves in fall (September to November, after the first light frosts but before the ground freezes) for harvest the next summer. It needs a cold period to form good bulbs. See when to plant garlic and how to grow garlic. Onions and shallots overwinter in mild zones, and cover crops like crimson clover or winter rye sown in fall protect and enrich beds through winter.

Fall planting windows by zone

Extending the season with protection

Simple covers push the fall harvest weeks or months later. Floating row cover adds a few degrees of frost protection and keeps late pests off; low tunnels and cold frames can carry hardy greens through winter in zones 5 and up. A thick straw mulch over root crops lets you harvest carrots, beets and parsnips from the ground long after the tops die back. Watering to establish late-summer sowings in warm, dry soil is the real challenge — mulch and consistent moisture get seedlings up.

Match the protection to how cold your winter gets. In zones 3 to 5, a cold frame or a low tunnel with heavy row cover is what carries spinach, kale and mâche through hard freezes; on the coldest nights, a second layer of cover inside the tunnel adds several more degrees. In zones 6 to 7, a single layer of row cover on hoops is usually enough to keep hardy greens producing into or through winter. In zones 8 and up, most cool-season crops grow unprotected all winter, and covers are needed only for the occasional cold snap. Remember that plants under cover still need light and occasional water, and that covers should be vented on mild, sunny days so trapped heat does not cook the crop.

Preparing beds after summer crops

Fall crops usually follow spent summer vegetables, so the bed needs refreshing before you replant. Pull out finished plants, clear debris that harbors pests and disease, and work 1 to 2 inches of fresh compost into the top few inches of soil to replace nutrients the summer crop used. Because leafy fall greens are nitrogen-hungry, a light dose of a balanced or nitrogen-leaning feed at planting pays off; owners consistently favor general vegetable formulations ranked in best vegetable garden fertilizer. Mind crop rotation: do not follow one brassica (broccoli, kale, cabbage) with another in the same bed, since they share soil diseases like clubroot — rotate greens into ground that held beans, squash or tomatoes over summer.

The single hardest part of fall gardening is germinating seed in warm, dry late-summer soil. Sow a little deeper than in spring so seeds reach cooler, moister soil, water daily until seedlings emerge, and shade the row with a board or light cloth for the first few days. A thin mulch over the row holds moisture during this critical window. Once cooler weather arrives, watering needs drop sharply.
