Fall Planting Guide: What to Grow in Each Zone (2026)

Fall Planting Runs on a Countdown

Spring planting counts forward from your last frost: wait until danger passes, then plant. Fall planting counts backward from your first frost: a crop that needs 60 days to mature must be in the ground 60-plus days before frost ends the season. Miss the window by two weeks and you harvest baby carrots — or nothing.

That makes one number the anchor of everything below: your zone's average first fall frost, from NOAA climate normals.

These are 30-year statistical averages, not guarantees — your actual first frost can land two weeks either side. Treat the date as the center of a window, and when in doubt, plant a week early.

Garlic: The One Crop That Must Be Planted in Fall

Everything else on this page has a spring alternative. Garlic doesn't — it needs weeks of winter chill (vernalization) to divide into a proper bulb, so fall planting isn't an option, it's the whole method. Plant individual cloves pointy-end up, two inches deep, right around your first frost date: the clove roots in before the ground freezes, sleeps through winter, and bulbs up for harvest the following summer.

Timing by zone: around Oct 1 in zone 6a, Oct 15 in 7a, Nov 10 in 8b, and late November in 9a. Planting too early produces lush top growth that winter kills; too late and roots don't establish. The same schedule applies to shallots. Buy seed garlic from a nursery or seed company rather than planting supermarket bulbs, which are often treated to prevent sprouting.

Zone-by-Zone Strategy

Zones 3–4 (first frost Sep 1–15): Your fall window is short and starts in June. By midsummer, the long-lead crops are already in; from here, stick to the 30–45 day sprinters — radishes, arugula, and spinach — and lean on row cover to stretch the season a few weeks past first frost.

Zones 5–6 (first frost Sep 20–Oct 10): The classic fall garden. July is for brassicas and roots, August for beets and peas, early September for greens. Garlic goes in around the frost date itself. This is the schedule most fall-gardening advice implicitly assumes.

Zones 7–8 (first frost Oct 15–Nov 10): You have the luxury of waiting out the August heat — hot soil is the main enemy of fall germination here. Sow brassicas in late July to mid-August, greens through September, and expect to harvest kale and carrots well into December. Frost sweetens both.

Zones 9–10 (first frost late Nov–Dec, or never): Flip the calendar: fall is your spring. The crops that bolted in June — lettuce, spinach, cilantro, peas — grow beautifully from October through March. Fall planting here isn't a race against frost; it's the start of your best growing season.

Five Rules That Make Fall Gardens Work

1. Add a "fall factor" to maturity times. Seed packets assume lengthening spring days. In fall, days shrink and growth slows — add 10–14 days to the packet's days-to-maturity when deciding if a crop still fits your window.
2. Beat hot-soil germination failure. Lettuce and spinach won't germinate in 85°F soil. Sow in the evening, water deeply, and shade the seedbed with a board or shade cloth until sprouts appear — or start seeds indoors and transplant.
3. Clear and refeed beds first. Fall crops follow heavy spring feeders. Pull the spent plants, add an inch of compost, and you've replaced most of what tomatoes and squash took out.
4. Water more than you think. Late-summer sowings face the year's driest soil. Germinating seeds need consistent moisture — a missed watering week one can end the crop.
5. Let frost improve the flavor. Don't rush to harvest kale, carrots, or Brussels-family crops at the first cold snap. Light frost converts starches to sugars — December carrots from a zone 7 garden are candy compared to July ones.
