Lettuce Succession Plant Your Way to All-Season Harvests

I planted all my lettuce at once for three years before someone finally told me you weren’t supposed to do that. What you get is roughly eleven days of more salad than your family wants, and then the plants bolt in July while you stand there holding a colander feeling personally betrayed. Took me an embarrassingly long time to fix it.

Succession planting is what fixed it. Stagger your sowings every two to three weeks and instead of a flood you get a steady trickle all season. Simple idea. Somehow it took me until year four to actually do it.

Why April Is the Best Time to Start This

Here in the Pacific Northwest, April is basically the starter pistol. The grey is finally breaking, soil temps are creeping up, and you’ve got a long enough runway to get multiple rounds of cool-season crops in before summer heat shuts everything down. Start succession planting now and you can be harvesting lettuce, spinach, and radishes clear into October without a single gap.

That’s the goal. Continuous harvests, no feast-or-famine nonsense, and definitely no more standing over the compost bin dumping bolted lettuce heads. (We don’t talk about 2021.)

The Basic Idea (and Why It’s Free)

You don’t need a special system. You need a calendar and a cheap pen. I literally use graph paper taped to the inside of my garden shed door. Every two to three weeks, I sow a new short row of whatever I’m succession planting. That’s the whole method.

When one row is getting harvested, the next one is a few weeks behind it, and another one behind that. You’re always two to three rows deep in production. Which, now that I think about it, is basically running a tiny conveyor belt out of your backyard. For free.

What to Succession Plant (and What Not To)

Not everything needs this treatment. Tomatoes, squash, peppers, you plant those once and you’re done. Succession planting is for the fast-maturing stuff that either bolts in heat or gets exhausted quickly.

Good candidates for succession planting here in zone 8b:

• Lettuce — every 2-3 weeks, April through early August. After that the heat makes it grumpy.
• Spinach — same rhythm as lettuce, and it’ll come back around in September for a fall round too.
• Radishes — these are almost cheating. Ready in 25-30 days. Sow a short row every two weeks and you’ll have more radishes than you ever wanted. (My daughters use them as pretend food. Fair.)
• Cilantro — bolts fast in heat, but if you keep sowing every few weeks you stay ahead of it. Great for tacos. Non-negotiable for tacos.
• Bush beans — start these in late May and sow a new round every three weeks through June. You’ll be picking beans in waves instead of drowning in one giant harvest you can’t keep up with.

Carrots are worth mentioning because they’re a bit trickier. They take longer to germinate and the seeds are genuinely frustrating to plant evenly. I started using carrot seed tape a couple seasons ago and it made succession sowing them a lot less annoying. You just cut the tape to whatever row length you want. Tiny thing, but it helps.

How to Actually Track It Without Losing Your Mind

The part that trips people up is keeping track of what got planted when. I forgot to write things down my first year of doing this and ended up with four rows of lettuce all planted the same week because I couldn’t remember what I’d done. Classic.

Now I use a simple paper chart. Column one is the crop, column two is the date I sowed it, column three is when to sow the next round. That’s it. A $0.79 spiral notebook from the hardware store checkout has served me faithfully for three seasons now.

You could also use a dedicated garden journal if you want to feel fancy about it. I am not that fancy. But some people are and that’s fine.

A Few Things That Tripped Me Up Early

Planting too much per round. You don’t need a six-foot row of lettuce every two weeks unless you’re feeding a large family or a very committed rabbit. A short row, maybe two feet, is usually plenty for us. Start small and adjust.

Forgetting to account for days-to-maturity. Radishes mature in 25 days. Carrots take 70-80 days. Your two-week sowing interval means something very different for each of those. Check the seed packet and work backward from your first expected frost in October.

Also, I once tried to succession plant zucchini. I will not be doing that again. One zucchini plant is already more than enough. Two staggered plantings of zucchini is a lifestyle I was not prepared for.

Start This Weekend

If you’re in the Pacific Northwest and it’s April, your timing is perfect right now. Get a short row of lettuce in the ground today, mark the date, and set a reminder to sow again in two weeks. Do that four or five times and you’ll be harvesting salad greens well into fall.

No special tools, no expensive setup. Just a little patience and a slightly better memory than I had in year one. Growth mindset. (Gardening pun. Sorry.)
