Succession Planting: Keep the Harvest Coming All Season
Updated June 2026 · SowWhen
The classic beginner's mistake is to sow a whole packet of lettuce, or a full row of bush beans, all on the same day. Three weeks later everything is ready at once, you eat salad for a fortnight, and then the patch is bare for the rest of the summer. Succession planting is the fix: sow the same crop in small, staggered batches so the harvest arrives as a steady trickle instead of a single flood.
The basic method: sow little and often
Pick a fast-maturing, "pick it now" crop and sow a short row every two to three weeks instead of one long row at once. As one batch is finishing, the next is coming on. The crops that reward this best are lettuce and salad greens, radishes, bush beans, spinach, arugula, cilantro, dill, and baby carrots — anything quick that peaks and then bolts or toughens. A few feet sown biweekly keeps a small kitchen garden in salad for months.
Two other kinds of succession
There's more than one way to succeed a crop. The first is following one crop with another in the same bed: pull spent spring peas in early summer and drop heat-loving beans or a late planting of squash into the vacated space. The second is staggering varieties with different maturity dates — an early, a mid, and a late sweet corn sown the same day will ripen in three waves rather than all at once. Both stretch a bed's output without needing more ground.
Your season length sets the limits
Every succession sowing still needs enough frost-free days to mature before the fall frost shuts the window. The last useful sowing date for a crop is its days-to-maturity counted backward from your first fall frost, plus a week or two of padding because plants grow more slowly as the days shorten and cool. Miss that date and the final batch won't finish. This is exactly the kind of counting that's easy to get wrong by hand.
Let SowWhen watch the window for you
SowWhen flags which crops still have an open succession window in your zone and roughly how many weeks of sowing you have left before the fall frost makes another round pointless. Check in every couple of weeks through spring and summer, sow the next short batch of whatever the calendar still shows as open, and you'll pull the garden out of the boom-and-bust cycle and into a steady, season-long supply.
