Most articles on succession planting include color-coded spreadsheets, day-counting formulas, and elaborate planting calendars. The result is intimidating enough that most home gardeners skip succession planting entirely and accept the boom-then-nothing harvest pattern that comes from single plantings.
A simpler approach works for most home gardens. A small notebook, a regular planting rhythm, and an honest assessment of what your household actually eats. We have run succession plantings this way for several years; the kitchen impact is significant and the planning effort is small.
Why succession planting matters
A single planting of lettuce produces all its harvest within a 2-3 week window. By the end of that window, the plants bolt to flower in summer heat and the harvest ends. The bed sits empty until you plant the next crop.
Multiple smaller plantings spaced 2-3 weeks apart produce continuous harvest from spring through autumn. Each planting is mature when the previous one is finishing. The kitchen has fresh lettuce for months instead of weeks. The same bed produces three to four times more total harvest.
The principle applies to most short-season crops: lettuce, radishes, beans, beets, carrots, cilantro, dill, scallions, and many others. The pattern fails only for longer-season crops where a single planting takes the entire growing season anyway (tomatoes, peppers, winter squash).
The simple rhythm method
Instead of calculating exact dates, use a recurring rhythm: plant the same small amount of certain crops every 2-3 weeks throughout the season. The rhythm becomes part of your weekly routine, like watering or weeding.
- Every 2 weeks throughout the growing season: a small planting of lettuce, radishes, scallions
- Every 3 weeks: a planting of beans, beets, carrots, cilantro
- Every 4 weeks: a planting of summer squash (if growing for continuous harvest rather than glut)
- Spring only (single plantings work): peas, broccoli, cabbage, kohlrabi (do not succession-plant in summer; they bolt in heat)
- Autumn separately: a complete second round of cool-season crops in August-September
How small is a "small planting"
For a household of 2-4 people, a small succession planting is much smaller than people initially think.
- Lettuce: 4-6 plants per planting, enough for 2 weeks of regular salads
- Radishes: 12-20 seeds per planting (a single 18-inch row)
- Beans (bush): 12-15 plants per planting (a single 4-foot row)
- Beets: 12-15 seeds per planting
- Carrots: 30-40 seeds per planting (a 2-foot row)
- Cilantro: 20-25 seeds per planting (1-foot patch)
- Summer squash: 1-2 plants per planting (rotate as previous plants slow)
The notebook system
A simple paper notebook is more useful than any spreadsheet. Each Sunday, take 5 minutes to write the next week’s planting plan based on what you planted 2-3 weeks ago.
Use this simple format: date at top, then a list of what got planted that day. Example: April 28 – 6 Black-Seeded Simpson lettuce, 20 radish seeds (Cherry Belle), 1 row beets (Detroit Dark Red).
This is enough information. You do not need to track expected harvest dates; the plants tell you when they are ready. You do not need to track exact spacing; you developed a sense for that. The notebook just maintains the rhythm.
After one season, you have a complete record of what worked when. The notebook becomes the template for next year, refined by experience.
When the rhythm shifts
Several conditions warrant adjusting the schedule.
Cool-season crops in summer heat: stop succession-planting lettuce, radishes, cilantro, and other cool-season crops when summer heat consistently hits 85F+. They bolt before producing anything useful. Resume in late August for autumn harvest.
Heat waves: skip a planting if you cannot reliably water it during establishment. New seeds need consistent moisture; planting just before a heat wave you will not be home for is wasted seed.
End of season: stop succession planting once you reach 60 days before your average first frost (50 days for fast crops). Plantings later than this run out of growing season before producing meaningfully.
Crop rotation: shift each succession planting to a different bed area to avoid soil disease build-up. Same lettuce variety in the same bed for the whole season is more disease-prone than rotating around the garden.
A starter succession schedule
For a zone 6 garden, here is the basic year-long rhythm:
- Early April: first plantings of peas, spinach, radishes, lettuce
- Mid-April: first succession of lettuce, radishes, beets, carrots
- Early May: next succession of lettuce, radishes; first bush beans
- Mid-May to late June: continue lettuce/radish/bean/beet rhythm every 2-3 weeks
- July: pause cool-season succession; continue beans and summer squash
- Early August: resume succession plantings of lettuce, radishes, beets for autumn
- Mid-August: last bush beans for the year (60 days to maturity)
- Late August: last succession of lettuce, spinach, kohlrabi for autumn
- September: final cool-season seedings; spinach and mache for late autumn harvest
Succession planting transforms a garden from boom-bust harvest cycles into continuous production. A simple notebook rhythm replaces complex spreadsheets. Small plantings replace overwhelming gluts. The kitchen gets consistent fresh vegetables for months instead of weeks. Start with two crops (lettuce and radishes) on a 2-week rhythm; once that becomes habit, expand to other crops.
The biggest succession mistake we still see
The most common pattern that breaks succession planting is planting the same large quantity of one crop every two weeks throughout the season. By August you have lettuce overflowing from every bed, none of it harvested in time, all of it bolting in the heat.
The fix is to taper quantities seasonally. Plant fuller plantings in spring and fall when conditions favor the crop. Plant tiny amounts during summer when the heat works against cool-season crops. For lettuce specifically:
- April through mid-May: full plantings of 6-8 plants every two weeks
- Late May through July: reduced plantings of 3-4 heat-tolerant varieties only
- August: skip lettuce entirely; resume in late August for fall
- September through October: full plantings of 6-8 plants every two weeks
- November: cold-hardy varieties only, with row cover ready
This rhythm produces continuous useful harvest without the August disaster of bolted lettuce. The discipline is to plant less when conditions are wrong, even if you have empty space; resist the urge to fill that space with another full lettuce planting that will fail.
