Succession Planting
Staggering multiple sowings of the same crop at intervals of 2-4 weeks to spread the harvest over a longer season rather than producing one large glut.
Succession planting solves one of the most common garden problems: too much of one thing at once, then nothing. A single large planting of lettuce produces 20 heads ready in the same week. Half go to waste. Succession planting spaces those 20 heads across two months of harvest.
How It Works
Instead of sowing the whole packet at once, you sow a portion now, another portion in 2-3 weeks, another in 2-3 more weeks, and so on through the season. Each sowing matures at a different time, giving you a staggered, manageable harvest.
The interval depends on the crop’s days to maturity. For radishes at 25 days, a 2-week interval gives continuous harvest. For beans at 55 days, a 3-week interval works. The goal is to start harvesting the second planting just as the first is finishing.
Crops Where It Makes the Most Difference
Fast crops with short harvest windows: radishes, lettuce, spinach, cilantro, dill, and arugula reach peak quality and quickly decline (bolting, toughening). One planting gives you a week or two of harvest. Three successions give you six weeks.
Continuous-harvest crops: beans are worth succession planting because a single planting peaks and then slows. Two or three plantings keep production at a usable level through summer.
Storage crops: root vegetables like carrots and beets can stay in the ground, so succession matters less for immediate harvest. But for fresh eating of tender young carrots, succession keeps the supply of young roots coming.
Season Limits
Succession planting has hard limits set by the calendar. Cool-season crops (lettuce, spinach) can’t be planted through summer heat. Stop succession planting these crops when daytime temperatures will consistently exceed 75-80°F before the new sowing reaches harvest. Resume in late summer for fall successions.
For warm-season crops, stop succession planting when a new sowing won’t have time to mature before first fall frost. Use the crop’s days-to-maturity figure and work backward from your frost date.
Same Variety vs. Multiple Varieties
Two approaches to succession planting exist and both have merit.
Planting the same variety at intervals is simpler - you know exactly what you’ll get each time and can plan harvest quantities accurately.
Planting different varieties with staggered maturity dates achieves succession without multiple sowings. A “quick” lettuce at 45 days and a “slow” one at 70 days, planted simultaneously, give you harvest at two different points. Many seed catalogs offer collections specifically designed this way.
Succession Planting and Bed Space
The limitation in most home gardens is not seed cost or labor - it’s space. Succession planting requires empty bed space to receive new sowings while earlier plantings are still growing. Fast crops like radishes and lettuce free up space quickly. Slow crops like tomatoes tie up a bed all season. Plan your successions around space availability, not just timing.
One practical approach: succession sow into the edges of existing plantings. As one succession is harvested, the next is maturing in an adjacent area. Fast-maturing crops like radishes can be interplanted between slow crops like tomatoes or peppers, filling space while the main crop develops.
