Fall planting schedule by USDA zone

Last updated 2026-05-18 · 8 min read

Fall is the most underrated planting season of the year. While spring gardeners are wrestling with cold soil and slug damage, fall gardeners get warm soil, cooling air, and reliable autumn rain — the exact conditions that let roots establish without leaf stress. This guide covers what to plant in fall by USDA zone 3 through 10, with specific date windows for bulbs, trees, shrubs, and the cool-season vegetables that often produce better in fall than in spring.

A note before the calendar: USDA zones are based on the average annual minimum winter temperature, not on growing-season length. Two zone-6 gardens might have very different first-frost dates depending on how far north or south they are. If you know your local first-frost date (a quick search by zip code will give it to you), use that as the anchor for these schedules — the zone numbers below are intended as a starting framework, not a precise calendar.

Why fall planting actually works

A spring-planted perennial spends its first season building a tiny root system while simultaneously pushing leaves and flowers above ground. A fall-planted perennial dumps everything into roots because the top has nothing to do — and by the time spring arrives, it is already established.

The same logic applies to trees, shrubs, and bulbs. Soil temperatures stay warmer than air temperatures through October and often into November, so roots keep growing for weeks after the gardener thinks the season is over. The result: bigger spring growth, less watering, and a far higher survival rate for trees and shrubs.

The only catch is timing. Plant too late and roots do not establish before the ground freezes — the plant either dies or limps into spring barely rooted. The tables below give you the safe window for each zone.

Zone-by-zone fall planting calendar

Zone 3 (average last frost mid-May, first frost early September)

• Bulbs: Late August through mid-September. Daffodils, tulips, crocus, alliums.
• Trees and shrubs: Mid-August through mid-September. Get at least 4 weeks before hard frost.
• Perennials: Same window — late August through mid-September.
• Vegetables: Limited. Garlic in late September, mulched heavily.

Zone 4 (last frost mid-May, first frost late September)

• Bulbs: September through early October.
• Trees and shrubs: Late August through late September.
• Perennials: Through late September.
• Vegetables: Garlic in early October. Spinach and kale will overwinter under mulch if seeded in early September.

Zone 5 (last frost early May, first frost early October)

• Bulbs: September through mid-October.
• Trees and shrubs: Through mid-October. The single best zone-5 month for woody plants.
• Perennials: Through early October.
• Vegetables: Spinach, kale, mache, and arugula seeded in late August. Garlic in mid-October.

Zone 6 (last frost mid-April, first frost mid-October)

• Bulbs: Mid-September through late October.
• Trees and shrubs: September through late October.
• Perennials: Through mid-October.
• Vegetables: Lettuce, spinach, kale, radish, turnip seeded mid-August through mid-September. Garlic in mid-to-late October.

Zone 7 (last frost early April, first frost early November)

• Bulbs: October through early November.
• Trees and shrubs: September through early November.
• Perennials: Through late October.
• Vegetables: Lettuce, spinach, kale, broccoli, cauliflower, chard transplants late August through mid-September. Garlic in late October.

Zone 8 (last frost mid-March, first frost mid-November)

• Bulbs: November (after soil cools below 60 °F). Tulips and hyacinths in many zone-8 areas need pre-chilling in the refrigerator for 8–10 weeks before planting.
• Trees and shrubs: October through November — arguably the best planting window of the entire year for zone 8.
• Perennials: September through November.
• Vegetables: A full second season. Lettuce, spinach, kale, broccoli, cabbage, cauliflower, carrots, beets, radish — start transplants indoors mid-August, set out in September.

Zone 9 (last frost early February, first frost early December)

• Bulbs: Most spring bulbs need pre-chilling here. Naturalizing options that don't: paperwhites, Spanish bluebells, leucojum.
• Trees and shrubs: October through December. The dormant season is the ideal planting season — no heat stress.
• Perennials: Through November.
• Vegetables: Cool-season crops September through November. This is the main growing season in many zone-9 areas — summers are too hot for lettuce and broccoli.

Zone 10 (essentially frost-free)

• Bulbs: Most spring bulbs do not naturalize without a cold cycle. Treat tulips and hyacinths as annuals with pre-chilled bulbs, or focus on warm-climate bulbs: amaryllis, crinum, society garlic.
• Trees and shrubs: November through February — the cool season is the planting season.
• Perennials: Through winter.
• Vegetables: Year-round, but tomatoes and peppers do best with fall planting (October) for a winter and spring harvest before summer heat ends production.

Spring-blooming bulbs: timing in detail

Bulb timing is driven by soil temperature, not air temperature. The trigger for planting most spring bulbs is soil that has dropped below about 60 °F at a 6-inch depth.

• Tulips. Need 12–14 weeks of cold below 50 °F to bloom. In zones 3–7 plant them outdoors in autumn and the winter does the work. In zones 8–10 chill them in the refrigerator (away from ripening fruit, which gives off ethylene) for 10–12 weeks, then plant in late December or January.
• Daffodils. The most forgiving spring bulb. Plant any time soil is workable and below 60 °F. Naturalize for decades in zones 3–8.
• Crocus. Plant September through November in zones 3–8. The earliest spring color you can buy.
• Alliums. Big-headed ornamental onions. Plant October through November in zones 4–8.
• Hyacinths. Plant October through November in zones 4–8. Like tulips, need pre-chilling in zones 8–10.

Trees and shrubs: fall is the season

Bare-root trees go in spring. Container-grown and balled-and-burlapped trees go in fall and they always establish faster than spring plantings. The only exceptions are species with marginal cold hardiness for your zone — magnolias and crepe myrtle in zone 6, for instance, prefer spring.

Water deeply once a week through the first month, then once every two weeks until the ground freezes. Mulch 3 inches deep but keep the mulch pulled back from the trunk to prevent rot.

Cool-season vegetables

Many cool-season crops produce better in fall than in spring because they finish during the shortening, cooling days they evolved for — instead of bolting in late-spring heat.

• Lettuce, spinach, arugula. Direct-seed about 4–6 weeks before first frost. Tolerate light frost; spinach often overwinters under row cover.
• Kale and chard. Transplant 6–8 weeks before frost. Kale tastes sweeter after frost converts starches to sugars.
• Broccoli, cabbage, cauliflower. Transplant 10–12 weeks before frost. Need a head start; usually started indoors in late July.
• Carrots, beets, radishes, turnips. Direct-seed 8–10 weeks before frost. Root crops hold well in the ground after frost.
• Garlic. Plant 4–6 weeks before the ground freezes solid. Roots establish before winter; the green tops emerge in early spring; harvest the following July.

Cover crops and soil-building fall plantings

If a vegetable bed will sit empty through winter, plant a cover crop instead of leaving bare soil. Bare soil is the worst possible state for garden beds — it loses nutrients to leaching, compacts under rain, and grows whatever weed seeds are already there. Good fall cover crops:

• Winter rye. Cold-hardy to about zone 4. Direct-seed September through October. Cut down in spring two weeks before planting and the residue smothers weeds.
• Crimson clover. Fixes nitrogen from the air. Best in zones 6 and warmer.
• Hairy vetch. Another nitrogen fixer, hardy to zone 4. Pair with winter rye for the classic green-manure mix.
• Oats and field peas. Winter-kill in zones 5 and colder, which means no mowing in spring — the dead residue is your mulch.

Microclimates: the secret zone shift

Most properties have at least one microclimate that effectively shifts you up or down a half-zone. Knowing where they are lets you push the recommended dates and grow plants that "should not" survive in your zone:

• South-facing walls. Reflect heat back into the bed and stay measurably warmer than the open yard. A south wall in zone 5 can grow plants rated to zone 6.
• Low spots. Cold air pools at ground level. A bowl-shaped low spot is effectively a half-zone colder than the surrounding yard.
• Urban heat island. A city yard is reliably warmer than a rural one in the same county — sometimes a full zone warmer.
• Lake and ocean edges. Large bodies of water moderate temperatures and push the first-frost date later by 2–3 weeks.

Common fall planting mistakes

• Fertilizing newly planted trees and shrubs. The plant is putting its energy into roots, not leaves. Nitrogen pushes top growth that the roots cannot support. Skip fertilizer in fall; apply once in spring.
• Stopping watering "because it's cool". Cool air does not equal moist soil. Newly planted material needs water until the ground freezes. A long deep soak the week before freeze-up is the single most important watering of the year.
• Forgetting to mulch. The freeze-thaw cycle heaves shallow-rooted plants right out of the ground. 3 inches of mulch around the root zone (not against the trunk) prevents this.
• Planting heat-loving perennials in late fall. Lavender, rosemary, butterfly bush, and crepe myrtle prefer spring planting in zones 5–7. Their root systems do not establish well in cold soil.
• Buying bulbs that "look small". Bulb size matters. A 12 cm tulip bulb produces a bigger flower than an 8 cm bulb of the same cultivar. Buy from a reputable supplier and check the bulb-size grade on the label.

One-shot timing rule

When in doubt, plant 6 weeks before the average first hard frost in your area. That gives roots time to establish without exhausting the plant. The exception is bulbs, which want soil at 60 °F or below — usually 4–6 weeks after that 6-week mark.
