Succession Planting — Harvests All Season

What You'll Learn
Learn how to stagger your plantings for a continuous supply of fresh food from spring through fall — no more feast or famine.
The End of Feast and Famine
The most common beginner mistake — after overwatering — is planting everything at once. You get one glorious harvest in July, then nothing for the rest of the season. Your garden goes from overflowing to empty in a single week, and you end up buying lettuce at the grocery store in August with fifteen bolted lettuce plants still in the ground.
Planting the same crop multiple times at regular intervals throughout the season to ensure a continuous, manageable harvest rather than one overwhelming glut. fixes this completely. Instead of planting 20 heads of lettuce at once, you plant 5 every two weeks. Instead of 6 rows of beans on the same day, you plant 2 rows every three weeks. The result: fresh food all season long, in manageable quantities that match what you'll actually eat.
It's the single technique that separates "I had a great summer harvest" from "we ate from the garden every night from May to October."
The Succession Planting Schedule
Here's which crops reward succession planting, how often to replant, and roughly how much to plant each time. The quantities assume a family of two eating salads a few times a week — scale up or down to match your household.
Every 2 weeks — the fast bolters and constant-harvest crops:
- Lettuce — the classic. A short row (6–8 plants) every 14 days keeps salads rolling from April through October.
- Radishes — ready in 25 days, bolt quickly once mature. Sow a small band (2 feet of row) every 10 days.
- Spinach — excellent for spring and fall, but it bolts hard in summer heat (skip midsummer plantings).
- Cilantro — goes to seed fast. A small patch every 2 weeks keeps a fresh supply.
- Arugula — fast, peppery, same bolt-behavior as cilantro.
Every 3 weeks — the warm-season producers:
- Bush beans — plant a new row every 3 weeks to replace the one that's finishing. Each planting produces for about 3–4 weeks.
- Summer squash / zucchini — a single plant produces for 6–8 weeks, but a second planting in July means fresh zucchini all the way to frost.
- Asian greens — bok choy, mizuna, tatsoi. Quick, productive, predictable.
Every 4 weeks — the slower-bolting herbs and greens:
- Basil — young plants taste better than old. A new batch every 4 weeks gives you peak-flavor leaves all summer.
- Dill — goes to seed fast. Successive sowings keep feathery fresh leaves coming.
- Kale — a single planting often lasts all season if you harvest outer leaves, but a second sowing in July gives you a tender fall crop.
Direct-seed vs transplant. Fast crops with tiny seeds (lettuce, radishes, spinach, arugula, cilantro) succession best from direct-seeding — sow right in the garden every 2 weeks, no transplant shock. Slower crops with bigger roots (basil, brassicas, Asian greens) work well both ways, but transplants give you a 2–3 week head start and let you tuck them into gaps as other crops come out.
Don't bother successioning:
- Tomatoes, peppers, eggplant — one planting per season. Once they start producing, they produce for 8–12 weeks straight.
- Onions, garlic, leeks — one planting cycle per year. You plant once and harvest once.
- Large root vegetables (carrots, beets, parsnips) — plant one major spring batch and one late-summer batch for fall harvest. Don't over-succession.
- Perennials — rosemary, thyme, chives, oregano, mint, asparagus. Plant once, harvest for years.
Tip
The simplest succession strategy, if you can't bring yourself to plan: every time you harvest something, plant something new in that spot. Pulled your radishes? Sow lettuce. Harvested your lettuce? Plant beans. Your garden stays productive from spring to fall with zero spreadsheet.
Relay Planting — Crop After Crop
A form of succession planting where you plant a new crop in the same space immediately after harvesting the previous one. Also called "follow-on planting." It maximizes production from a single garden bed throughout the season. takes succession one step further. Instead of leaving a bed empty after harvest, you immediately plant the next crop in the same space.
- 1Early spring (April): Plant peas and lettuce — both cool-season.
- 2Late spring (June): Peas are done. Pull them out and plant bush beans (warm-season). Lettuce keeps going for now.
- 3Midsummer (July): Beans in the other half of the bed. When lettuce bolts, pull it and plant kale or a second round of beans.
- 4Early fall (September): Beans are done. Plant spinach or overwintering garlic in their place.
That's four or five different harvests from a single bed in one year. The key is the The number of days from sowing (or transplant) to first harvest for a given crop. Critical for planning relay and fall-succession planting — you need to know how long each crop takes to determine whether there's enough time before frost for another round. arithmetic — if you have 60 days between the end of one crop and your first frost, and kale takes 55 days, you've got time. If you only have 45 days and the next crop needs 60, pick something faster (radishes, lettuce, spinach).
Did You Know?
Experienced intensive growers routinely pull 6–8 different crops from a single bed in a year. They treat each bed like a conveyor belt — something is always going in, something is always coming out.
Spring vs Fall — The Difference Almost Nobody Explains
Here's the thing most succession-planting guides skip: spring succession and fall succession are not the same game.
In spring, days are lengthening and soil is warming. Plants grow faster with each passing week — a lettuce sown April 1 matures noticeably quicker than one sown March 1. You can use standard-maturity varieties and things speed up as the season progresses.
In fall, the opposite happens. Days are shortening and soil is cooling. As of the The part of the year when daylight drops below 10 hours per day. During this window, plants essentially stop growing — not because of cold, but because there isn't enough light for photosynthesis. In most of North America this runs roughly November through January. (when daylight drops below 10 hours, roughly November through January in most of North America), plants essentially stop growing — not because of cold, but because of low light.
What this means in practice:
- For fall succession crops, pick fast-maturing varieties — a 45-day "Speedy Arugula" over a 60-day standard. Check the seed packet's days-to-maturity before buying for fall.
- Count backward from your first frost, then add 14 days (the "fall factor" — everything takes about 2 weeks longer as days shorten). If the packet says 50 days, plan 64 days before first frost.
- Stop succession-planting heat-lovers by early August in zones 5–6, mid-August in zones 7–8. A second round of bush beans in early August will barely produce before frost.
- Cold-hardy crops can go in right up to about 8 weeks before first frost — spinach, kale, lettuce, radishes, Asian greens.
A sample succession calendar for a zone 6b grower (last frost mid-May, first frost mid-October):
| Plant | Mar 15 | Apr 1 | Apr 15 | May 1 | May 15 | Jun 1 | Jun 15 | Jul 1 | Jul 15 | Aug 1 | Aug 15 | |---|---|---|---|---|---|---|---|---|---|---|---| | Lettuce | ● | ● | ● | ● | ● | | | | ● | ● | ● | | Radishes | ● | ● | ● | ● | | | | | ● | ● | ● | | Spinach | ● | ● | ● | | | | | | ● | ● | | | Bush beans | | | | | ● | | ● | | ● | | | | Basil | | | | | ● | | | ● | | | | | Kale | | ● | | | | | | ● | | | |
Every ● is a small planting — a short row or a handful of plants, not a full season's worth. The pattern is the whole point: steady, manageable, continuous.
Tip
Keep a small bag of lettuce and radish seeds tucked with your garden tools. Any time you're in the garden and see a patch of bare soil, scatter some and water them in. This opportunistic succession is the easiest form — no calendar needed, no planning, just the reflex of "bare soil = new seeds."
Interplanting — Growing Together
Growing fast-maturing crops in the spaces between slow-maturing crops. The fast crops are harvested before the slow crops need the space. Also called intercropping. is succession's cousin — growing fast crops in the spaces between slow crops. The fast crops are harvested before the slow ones need the room.
Practical combinations:
- Radishes between tomatoes. Plant radishes at the same time as tomato transplants. By the time the tomatoes need the space (4–5 weeks later), the radishes are harvested and gone.
- Lettuce under corn. Plant lettuce between corn rows in spring. Lettuce loves the partial shade from young corn and gets harvested before the corn canopy fully closes.
- Spinach between pepper plants. Same principle — spinach finishes while peppers are still filling out.
- Cilantro under sunflowers. Sunflowers provide light afternoon shade that keeps cilantro from bolting prematurely.
This is space efficiency at its maximum. Every square foot of your garden is producing something at all times.
Did You Know?
French intensive gardening, developed in the 19th century around Paris, used interplanting so effectively that tiny urban plots produced enough food to feed entire neighborhoods. Paris was nearly food-self-sufficient on small gardens within the city limits.
What This Means For You
Succession planting transforms your garden from a one-time event into a continuous supply:
- Plant lettuce, radishes, spinach every 2 weeks for non-stop salads
- Bush beans, summer squash, Asian greens every 3 weeks for continuous summer harvest
- Basil, dill, kale every 4 weeks to keep flavor peaks rolling
- Don't succession tomatoes, peppers, onions, or perennials — they do the succession themselves
- Spring plantings speed up; fall plantings slow down — pick faster varieties for fall, add 14 days to any packet estimate
- Count backward from first frost and respect the Persephone period when days drop below 10 hours
- The simplest rule: when something comes out, something goes in. That alone gets you 80% of the benefit.
