Succession Planting: How to Harvest Fresh Vegetables All Season Long

There's nothing worse than harvesting your entire lettuce crop in one week, then having none for the rest of summer. Succession planting solves this feast-or-famine problem by staggering sowings to provide continuous harvests from spring through fall.

What Is Succession Planting?

Succession planting means sowing the same crop at intervals throughout the growing season. Instead of planting all your lettuce seeds at once, you plant a small batch every two weeks. The result: fresh harvests spread over months instead of all at once.

Three Approaches to Succession Planting

1. Same Crop, Staggered Sowings

Plant small amounts of the same vegetable at regular intervals. This works best for fast-maturing crops that you want continuously: lettuce, radishes, beans, and cilantro.

2. Same Crop, Different Varieties

Plant early, mid-season, and late varieties at the same time. They mature at different rates, extending your harvest window. Works well for tomatoes, corn, and peppers.

3. Different Crops in Sequence

Follow one crop with another as space becomes available. Harvest spring peas, then plant summer beans. Follow early lettuce with fall spinach. This maximizes bed productivity.

Best Vegetables for Succession Planting

Short-Season Crops (Plant Every 2-3 Weeks)

• Lettuce: 45-60 days to harvest; bolts in heat so succession is essential
• Radishes: 25-30 days; quick and easy to squeeze between other crops
• Spinach: 40-50 days; plant spring and fall, skip summer heat
• Cilantro: 21 days for leaves; bolts quickly, so replant often
• Bush beans: 50-60 days; make 3-4 plantings through summer

Medium-Season Crops (Plant 2-3 Times)

• Beets: 55-70 days; plant early spring and late summer
• Carrots: 70-80 days; sow spring through midsummer
• Cucumbers: 55-65 days; second planting extends harvest
• Summer squash: 50-60 days; replace spent plants midsummer

Long-Season Crops (Different Varieties)

• Tomatoes: Plant early, mid, and late varieties
• Peppers: Mix quick-maturing and long-season types
• Corn: Stagger plantings or use varied maturity types

Creating a Succession Planting Schedule

Step 1: Know Your Frost Dates

Identify your average last spring frost and first fall frost. These bookend your outdoor growing season and determine planting windows.

Step 2: Calculate Days to Maturity

Seed packets list days to maturity. Count backwards from your first fall frost to determine the latest planting date. Add buffer time for shorter fall days.

Step 3: Determine Intervals

For continuous harvest, plant at intervals of one-third to one-half the days to maturity. If lettuce matures in 45 days, plant every 15-22 days.

Step 4: Map It Out

Create a calendar showing each sowing date. Set reminders so you don't forget mid-season plantings when you're busy harvesting.

Sample Succession Schedule (Zone 6)

Lettuce

• April 15: First sowing (transplant outdoors May 1)
• May 1: Second sowing
• May 15: Third sowing
• August 1: Fall sowing resumes
• August 15: Late fall sowing

Bush Beans

• May 15: After last frost
• June 15: Second planting
• July 15: Final planting (check days before frost)

Radishes

• Every 2 weeks from April through May
• Skip summer heat (bolts and turns woody)
• Resume August through September

Tips for Success

Keep Seeds Handy

Store succession planting seeds in a convenient location. Out of sight means out of mind—you'll forget to replant.

Start Small

Plant only what you'll use between sowings. A 3-foot row of lettuce every two weeks provides plenty for most families.

Prepare Beds in Advance

Keep a section of your garden ready for the next planting. Add compost and rake smooth so you can sow quickly when it's time.

Note What Works

Keep records of planting dates and harvest times. Your microclimate differs from seed packet averages—adjust intervals based on experience.

Succession Planting in Containers

Container gardeners can succession plant too. Keep extra pots ready with fresh potting mix. As one container finishes producing, start the next round. Rotate crops through your best sunny spots.

Dealing with the Summer Gap

Heat-Sensitive Crops

Lettuce, spinach, and cilantro bolt (go to seed) in summer heat. Accept a gap in production, or try bolt-resistant varieties and provide afternoon shade.

Fill with Heat-Lovers

When cool-season crops take a break, succession plant heat-tolerant alternatives: Swiss chard instead of spinach, basil instead of cilantro.

Fall Succession Planting

Don't forget fall! Many crops grow better in cool autumn weather than hot summer. Resume succession planting 8-10 weeks before first frost for lettuce, spinach, radishes, and Asian greens.

Succession planting transforms your garden from a one-time harvest into an ongoing food source. Start with one or two crops this season, refine your timing, and expand from there. With practice, you'll have fresh vegetables from the last frost of spring until the first hard freeze of fall.
