The Feast-or-Famine Problem
Without succession planting, most gardens produce a burst of any given crop followed by a long gap. Ten lettuce plants seeded on the same day produce ten heads of lettuce within the same two-week window — more than most households can eat, followed by nothing until the next planting. Succession planting staggers harvests by staggering plantings.
Two Types of Succession Planting
Time-staggered: Plant the same crop every 1–3 weeks through its growing season. Best for fast crops: lettuce, radishes, cilantro, arugula, green beans, beets, and spinach. Variety-staggered: Plant different varieties with different days-to-maturity simultaneously. A 60-day tomato and a 75-day tomato planted on the same day produce harvests two weeks apart. This works for crops where the timing between varieties is significant: corn (plant early, mid, and late varieties on the same day for sequential harvest), winter squash, and melons.
Key Succession Intervals by Crop
Lettuce: Every 2–3 weeks, spring through early summer; every 3 weeks in fall. Stop 8 weeks before first frost. Radishes: Every 10–14 days. Fast-growing (25–30 days to harvest) and perfect for succession. Green beans: Every 3 weeks from last frost through 10 weeks before first frost. Cilantro: Every 2–3 weeks — it bolts quickly in warm weather, so frequent small plantings maintain steady harvest. Basil: Every 3–4 weeks through summer. Start a new flat when the previous one starts to flower.
Calculating Backward from First Frost
The last succession planting of any crop should be timed so it reaches maturity before first frost. For a Zone 6 garden (first frost October 15): the last succession of green beans (days-to-maturity: 55 days) should be planted no later than August 21. Work backward: October 15 minus 55 days = August 21. Add a 1-week safety margin to account for cool temperatures slowing growth.

Practical Succession for Small Gardens
You don't need large amounts of space. In a 4x8 ft bed, succession-plant half the bed (4x4 ft) at a time: one half goes in Week 1, the other half in Week 3. When the first planting is harvested, it gets replanted. The result is continuous production from the same bed all season.
Crops That Should Not Be Succession Planted
Tomatoes, peppers, winter squash, melons, and sweet corn (without variety staggering) need long single seasons that don't allow for meaningful succession. Plant these once, in full, after last frost, and let them run the full season.
FAQ
How often should I succession plant lettuce?
Every 2–3 weeks gives the most consistent harvest. In hot summer climates, lettuce bolts quickly — plant heat-tolerant varieties (Jericho, Nevada, Muir) and shift to every 3 weeks to avoid harvesting faster than you can use it.
Can I succession plant tomatoes?
Not effectively in most climates — tomatoes need a full season and starting later just reduces your harvest window. The exception is zones 9–10 with a second summer planting season in late summer for a fall crop.
How many plants should I plant in each succession?
Base it on weekly consumption. For a family of four: 2–4 lettuce plants, 10–15 radish seeds, 6–8 green bean plants per succession. More isn't better if it creates harvest surplus you can't use.
What is the fastest crop to succession plant?
Radishes (25–30 days to maturity) and arugula (28–40 days) are the fastest. Microgreens are even faster (7–14 days), though they require replanting a tray rather than a bed.
Does succession planting work with raised beds?
Yes — raised beds are ideal for succession planting because you can easily section them and track exactly what's where and when it was planted. Use a simple planting log or phone photo of each section with the planting date.
