Lettuce Succession Plant (Or Eat Salad for a Week and Nothing for Two Months)

I planted all my lettuce at once for three years before someone finally told me you weren’t supposed to do that. You get roughly eleven days of more salad than your family wants, then everything bolts in a single warm week and you’re standing in the garden holding a colander feeling personally betrayed.

May is the sneaky-good month for this. You’ve still got time to stagger your sowings and eat well all the way into fall. The trick is not planting everything on the same Saturday just because you felt motivated.

Why Lettuce Is the Worst at Pacing Itself

Lettuce does not care about your meal planning. Direct sow a whole packet in one go and three weeks later you’ve got a surplus that would embarrass a farmers market vendor. Then it bolts. Then it’s bitter. Then it’s done.

The fix is embarrassingly simple. Sow a short row every two to three weeks instead of all at once. Or a single container. Or a patch the size of a cutting board. Each planting matures at a different time. Steady trickle instead of a flood. That’s lettuce succession planting, and I genuinely don’t know why it took me four seasons to figure it out, but here we are.

Where We’re At in May in the PNW

Here in Redmond, May is ideal. Soil temps are consistently in the 50s, lettuce germinates happily anywhere from 40 to 75 degrees, and we’ve still got enough cool weather ahead to get two or three more successions in before summer heat shuts the whole operation down.

Realistically you can keep direct sowing outdoors through late June, maybe early July if you’ve got afternoon shade. After that the days get too warm and lettuce just goes straight to bolt without even apologizing. Plant now, plant again in two weeks, plant again after that. Three successions gets you salad well into August.

If you want to push into fall, start your next round of seeds indoors in late July and transplant out in August when things cool back down. But that’s a whole other conversation.

How to Actually Do It Without Overcomplicating It

You do not need a spreadsheet. (I have a spreadsheet. You don’t need one.)

Just divide your seed packet into thirds. Sow the first third now. Put the rest in a labeled bag in your fridge. Set a reminder on your phone for two weeks out. That’s the whole system.

For container gardeners, a standard window box does one succession fine. I use whatever cheap loose-leaf lettuce seed mix is sitting on the discount rack at the garden center, usually a blend with different days-to-maturity across the varieties, which naturally staggers the harvest a little even within a single planting. Bonus frugality.

Cut-and-come-again varieties are your friend here. You harvest the outer leaves and the plant keeps producing. Black Seeded Simpson, any of the oak leaf types, those all do this well. Head lettuce is less forgiving because once you cut it, it’s done. I mostly grow loose-leaf for exactly this reason, and also because I’ve killed enough buttercrunch to know my limits.

One Mistake I Made (So You Don’t Have To)

First year I tried succession planting I marked my rows with little stakes that washed away in the rain. Classic. Couldn’t remember which row was which planting, harvested them all at once anyway, defeated the entire purpose.

Now I write the sow date directly on a piece of masking tape and stick it to a plastic fork pushed into the soil. Costs nothing. Survives Redmond drizzle. My daughters think it looks ridiculous, which is how I know it’s working.

What You’re Actually Aiming For

The goal is to never have more lettuce than you can eat in a week, but also to never run out. Which sounds basic but honestly took me embarrassingly long to get right.

If a succession gets away from you and starts bolting, pull it, toss it in the compost, and make sure the next one is already coming in. There’s almost no gap if the timing is right. You want that overlap. Two successions slightly overlapping is better than a gap where you’re buying bagged salad at the grocery store like some kind of animal.

May in the PNW is genuinely the best time to get this rhythm going. The weather cooperates, the seeds are cheap, and the payoff is real. Lettuce be honest, it’s the easiest win in the spring garden.

(I couldn’t help it. Sorry.)
