Succession planting - a steady harvest instead of a glut
Plant all your lettuce at once and you get a wall of it for two weeks, then nothing. Succession planting - small, staggered sowings - gives you a steady supply of the crops you eat continuously.
What you need
A crop you eat a little of continuously - salad greens, radishes, bush beans, cilantro
A short row's worth of seed every couple of weeks, rather than a whole packet at once
A simple note of when you last sowed, so the next sowing lands on time
Here's a beginner's mistake almost everyone makes once: you plant the whole packet of lettuce on the same day, and three weeks later you have more lettuce than any household could eat, half of it bolting to seed before you get to it - and then, just as fast, none at all. The fix is one of the simplest, highest-value habits in vegetable gardening, and it barely costs any extra work.
The idea: sow a little, often
Instead of planting a crop all at once, you stagger it - a short sowing now, another in two or three weeks, another after that:
Promising
Succession sowing at 2-3 week intervals extends harvest for short-DTM crops.
suboptimal if ignored → advise
Mechanism: Sowing the same crop in batches two to three weeks apart staggers when each batch matures, so the harvest arrives as a continual succession instead of one glut. It pays off only for short-DTM crops, whose quick turnaround lets several sowings ripen within a single season.
Evidence: confirmed against 1 source in the research-based literature.
Each small sowing matures a couple of weeks after the last, so instead of one overwhelming flush you get a steady trickle of exactly as much as you can use. The same total amount of seed, spread across a few dates, turns a glut-then-gap into a continuous supply. That's the whole trick, and for the crops it suits it's transformative.
Which crops it's for
Succession sowing pays off for fast, short-lived crops you harvest continuously and that don't hold long once ready:
Radishes - ready in weeks, woody if left; the textbook succession crop.
Bush beans - a single planting bears for a couple of weeks; stagger for a longer run.
Cilantro and dill - bolt fast in heat, so a fresh sowing every few weeks keeps leaves coming.
It is not for long-season, one-and-done crops. A tomato, a winter squash, or a pepper bears over a long stretch from a single planting, so there's nothing to stagger - plant those once and let them run.
The gap is the whole reason succession works: a radish clears the bed several times over before a pumpkin is ready to pick, so the fast crops are the ones worth re-sowing.
Days from sowing to first harvest, from the corpus. Each bar is the crop's range across cultivars; where a cultivar group is named, its own range.Source: corpus days_to_maturity — the species field, or a cultivar group's override where one is named.
The other kind of succession: follow one crop with another
There's a second sense of the word worth knowing: when an early crop finishes and frees its ground, you replant that space with a new crop rather than leaving it bare. Peas or early lettuce come out in early summer; beans, or a fall crop of greens, go in behind them. The one thing to check before you do is whether the follow-on crop has time to finish - count its days-to-maturity back from your first fall frost, exactly as the read a planting calendar guide describes. When you do follow one crop with another, mind the plant families too, so you're not setting up a rotation problem - the crop rotation guide has that.
How to actually keep it going
The only hard part of succession planting is remembering to do the next sowing, so make it easy: keep a one-line note of the date you last sowed each crop, and put the next sowing in when the last one comes up. Sow small - a few feet of row, not the whole packet. Ease off the heat-sensitive crops (lettuce, cilantro, spinach) through the hottest weeks, when they bolt no matter what, and pick them back up as the season cools. A little seed and a little attention, spread out, is all it takes to trade a two-week flood for a season-long supply.
