Most new gardeners plant everything on the same weekend in spring, which means everything is ready around the same time, and then nothing is ready for the rest of the season. Succession planting fixes that by staggering when you sow, so instead of one big harvest window you get a rolling supply.
What succession planting actually means
Instead of sowing an entire row of, say, radishes in one go, you sow a small batch every one to three weeks throughout the growing season. Each batch matures on its own schedule, so as one finishes, the next is a few weeks behind it and almost ready. Done well, it turns a single two-week glut into a steady trickle that lasts months.
Which crops actually need this
Not every crop benefits equally. Succession planting matters most for fast-maturing crops that have a short harvest window and don't hold well once they're ready:
- Lettuce and other salad greens: mature fast and bolt (turn bitter and go to seed) quickly once temperatures rise, so a new planting every 2 weeks keeps you in fresh greens.
- Radishes: ready in about 3-4 weeks and don't hold in the ground well past maturity, so staggering every 2-3 weeks keeps a steady supply.
- Arugula: grows fast and bolts within about two weeks of maturity in warm weather, one of the shortest windows of any common crop.
- Bush beans: each planting gives a concentrated harvest over about 2 weeks, then tapers off, so a new sowing every 3 weeks keeps beans coming.
- Cilantro: bolts fast in heat, so frequent small plantings beat one large one if you actually want a steady supply of leaves rather than seed (coriander).
Crops that don't need this: things that store well on the plant or that you harvest once per season anyway, like tomatoes, winter squash, and most fruit trees. There's no benefit to staggering a crop that keeps producing steadily or that you're only harvesting once regardless.
How to actually schedule it
Pick your interval based on the crop's typical days-to-maturity and how long its harvest window realistically lasts once ready. A crop that's only good for a week after maturing needs a shorter interval between sowings than one that holds for three weeks. As a starting point:
- Fast bolters (arugula, spinach, lettuce in warm weather): every 2 weeks
- Root crops with a short hold window (radishes): every 2-3 weeks
- Slower crops with a longer hold (beets, carrots): every 3-4 weeks
Stop new sowings early enough that the last planting has time to mature before your first fall frost or before summer heat shuts a crop down, whichever comes first for that crop. Count backward from your frost date using the crop's days-to-maturity, and add a couple of weeks of buffer.
A simpler alternative: interval-based reminders
Tracking every succession planting date by hand in a notebook is where most people give up on this. The easier version is just setting a recurring reminder at the right interval for each crop and sowing a small batch whenever it fires, rather than trying to plan an entire season's calendar up front.
Replant reminders, timed per crop
GardenWise reminds you to sow more arugula every 2 weeks, more carrots every 3, and skips crops like peas that don't benefit from it, all timed against your actual frost dates, not a generic calendar.
