Fall Vegetable Garden Planting Guide: What to Plant and When

Discover the best vegetables for fall planting and extend your harvest into winter. Complete timing guide with varieties and care tips.

Fall gardens often outperform summer gardens with cooler temperatures, fewer pests, and sweeter-tasting crops. Extend your harvest season by months with smart fall planting.

Why Plant a Fall Garden?

Fall gardening offers unique advantages:

Cooler temperatures: Plants thrive in moderate weather without summer heat stress

Fewer pests: Most garden pests decline as temperatures drop

Better flavor: Cool weather improves taste in many vegetables (especially greens and root crops)

Extended harvest: Enjoy fresh vegetables well into fall and early winter

Higher success rate: Easier than summer gardening in many regions

When to Plant for Fall Harvest

Work backwards from your first frost date to determine planting times. Each crop needs a certain number of days to mature before frost.

Find your first fall frost date:

  • Check your USDA hardiness zone
  • Ask local extension office
  • Use online calculators

Calculate planting date:

  • Days to maturity (from seed packet) + 2 weeks (for shorter fall days) = days before frost to plant

Example: If your first frost is October 15 and you want to grow lettuce (60 days to maturity):

  • 60 days + 14 days = 74 days before October 15
  • Plant lettuce around August 1-5

Best Vegetables for Fall Planting

Cool-Season Champions

These crops prefer cooler weather and taste better after light frost:

Leafy Greens (30-60 days):

  • Lettuce: Fast-growing, continuous harvest
  • Spinach: Incredibly cold-hardy, overwinters in many zones
  • Kale: Sweetens after frost, very hardy
  • Arugula: Spicy greens ready in 30-40 days
  • Asian greens: Bok choy, mizuna, tatsoi

Brassicas (50-80 days):

  • Broccoli: Plant transplants in late summer
  • Cabbage: Matures slowly, very cold-hardy
  • Cauliflower: Needs steady cool weather
  • Brussels sprouts: Sweetest after frost
  • Collards: Extremely hardy, harvest into winter

Root Vegetables (50-70 days):

  • Radishes: Ready in 25-30 days, plant every 2 weeks
  • Carrots: Sweeter with cool weather
  • Beets: Grow roots and greens
  • Turnips: Mild flavor after frost

Alliums (60-90 days for green onions, plant garlic in fall):

  • Green onions: Continuous harvest
  • Garlic: Plant cloves in fall, harvest next summer
  • Leeks: Very cold-hardy

Legumes (50-70 days):

  • Peas: Sweet, tender fall peas
  • Fava beans: Overwinter in mild climates

  • Second planting as temperatures moderate

November/December:

  • Garlic, onion sets
  • Many crops grow through winter

Step-by-Step Fall Garden Setup

1. Choose Your Location

Use the same beds where summer crops grew, or start fresh areas:

  • Full sun (at least 6 hours, though fall sun is less intense)
  • Good drainage
  • Easy access for fall and winter harvesting

2. Prepare the Soil

Fall garden prep is easier than spring:

  • Remove spent summer crops
  • Pull any weeds
  • Add 1-2 inches of compost
  • Till or turn in amendments
  • Rake smooth and level

Soil test: Fall is a great time to test soil and add amendments (lime, sulfur) for next spring.

3. Plant at the Right Depth

Direct seeding:

  • Plant slightly deeper than spring planting (soil is drier)
  • Carrots, radishes, turnips, beets: ¼-½ inch deep
  • Peas, beans: 1 inch deep
  • Lettuce, greens: ¼ inch deep or surface sow

Transplants:

  • Broccoli, cabbage, cauliflower: Plant deeper than spring (plants grow sturdier)
  • Water transplants well and shade for first few days

4. Water Consistently

Fall planting often coincides with hot, dry late-summer weather:

  • Keep soil consistently moist until germination
  • Water deeply 2-3 times per week
  • Reduce watering as weather cools
  • Monitor soil moisture; fall rains may provide enough water

5. Protect from Heat

If planting during hot weather:

  • Use shade cloth for first 2 weeks
  • Water more frequently until established
  • Plant in late afternoon or evening
  • Mulch lightly to keep soil cool

Extending the Harvest

Frost Protection

Light frost (28-32°F) damages tender crops but cool-season vegetables tolerate it well. Extend harvest with simple protection:

Row covers:

  • Lightweight fabric adds 2-4°F protection
  • Covers lettuce, spinach, greens
  • Easy to put on and remove
  • Lasts multiple seasons

Cold frames:

  • Bottomless boxes with transparent lids
  • Creates a mini-greenhouse
  • Adds 10-20°F of protection
  • Build from old windows or buy kits

Hoop houses/low tunnels:

  • PVC or wire hoops covered with plastic or row cover
  • Protects whole rows
  • Walk-in hoop houses protect large areas

Cloches:

  • Individual plant covers
  • Use for prized plants
  • Make from milk jugs, jars, or buy commercial versions

Deep mulch:

  • Cover root crops with 8-12 inches of straw or leaves
  • Keeps ground from freezing
  • Harvest carrots, beets, and parsnips all winter (dig through mulch)

Succession Planting

Sow small amounts every 10-14 days for continuous harvest:

Perfect for succession planting:

  • Lettuce
  • Radishes
  • Arugula
  • Spinach
  • Green onions

Plant from mid-summer through early fall (depends on your zone).

Harvesting Fall Vegetables

Frost-sweetened vegetables (harvest after light frost):

  • Kale, collards, Brussels sprouts, parsnips, carrots
  • Frost converts starches to sugars

Before hard freeze (harvest before temperatures drop below 25°F):

  • Lettuce, arugula (unless protected)
  • Root vegetables (or mulch heavily)
  • Cabbage, broccoli

Continuous harvest:

  • Lettuce: Pick outer leaves, let center grow
  • Kale, chard: Harvest outer leaves
  • Green onions: Pull as needed
  • Spinach: Cut and come again

Top Fall Varieties

Lettuce:

  • Winter Density: Cold-hardy romaine
  • Arctic King: Butterhead that tolerates frost
  • Salad Bowl: Fast-growing loose leaf

Kale:

  • Winterbor: Extremely hardy
  • Lacinato (Dinosaur): Dark blue-green, great flavor
  • Red Russian: Beautiful and tasty

Spinach:

  • Bloomsdale: Heirloom, cold-hardy
  • Space: Fast-growing, bolt-resistant
  • Tyee: Excellent cold tolerance

Broccoli:

  • Belstar: Reliable fall producer
  • Marathon: Late-season, large heads

  • Bolero: Disease-resistant

Radishes:

  • Cherry Belle: Classic round red
  • Watermelon: Beautiful interior
  • Daikon: Large white, good for storage

Common Fall Garden Challenges

Hot weather at planting: Shade new plantings and water frequently

Caterpillar pests (cabbage worms, loopers): More common on fall brassicas

  • Solution: Row covers or Bt spray

Slugs: Active in cool, moist conditions

  • Solution: Hand-pick, beer traps, diatomaceous earth

Bolting in warm weather: Greens bolt (go to seed) if planted too early

  • Solution: Wait for cooler weather or choose bolt-resistant varieties

Short days: Fall days are shorter, slowing growth

  • Solution: Add 2 weeks to maturity dates, plant earlier

Overwintering Crops

In zones 6 and warmer (with protection), many crops survive winter:

Hardy overwintering vegetables:

  • Kale, collards, chard
  • Spinach (very cold-hardy)
  • Mache (corn salad)
  • Garlic (plant in fall, harvest next summer)
  • Fava beans (zone 7+)

Protection needed:

  • Mulch heavily
  • Use cold frames or row covers
  • Choose cold-hardy varieties

Growth slows or stops in winter, but plants survive and resume growth in spring.

Your Fall Garden Action Plan

6-8 weeks before first frost:

  • Calculate planting dates
  • Order seeds or buy transplants
  • Prepare planting area

4-6 weeks before first frost:

  • Plant main fall crops
  • Water consistently during establishment

2-4 weeks before first frost:

  • Plant fast-maturing greens
  • Set up season extension supplies

At first frost:

  • Harvest tender crops
  • Add protection for hardy crops
  • Enjoy fall harvest!

The Bottom Line

Fall gardens are easier, more productive, and more rewarding than most gardeners realize. With proper timing and variety selection, you’ll harvest fresh vegetables long after summer gardens have finished.

Start small with a few easy greens and root crops. Success in your first fall garden leads naturally to bigger and more ambitious plantings in future years.

The growing season doesn’t end with summer. Plant a fall garden and discover how productive cool-season gardening can be!
