In spring and summer, I tend to grow my lettuce and greens as individual plants, and I harvest them by picking individual outer leaves. But during the cooler times of the year I often switch to the cut-and-come-again method, where I sow the seeds densely and harvest bunches of leaves with a knife.

Briefly, after a harvest, the plants look like stubs until they grow new leaves for you to cut again.

Lettuce just cut.

Seeds are relatively cheap for lettuce and greens, which is another reason to use this growing method. What follows is my experience with the cut-and-come-again method, especially as it relates to Southern California.

Varieties

I use any variety. For greens and lettuces alike, I try to mix colors and leaf shapes and textures because it’s more appealing to look at and eat.

Varieties of lettuce I sowed this past October.

Renee’s has this blend of lettuce varieties sold specifically for the cut-and-come-again style. The blend is also called a “baby mesclun” mix since the leaves are meant to be cut when small.

Keep in mind that the different types of lettuce and greens grow at different speeds and to different sizes so some will crowd others and the slower or smaller types seem to disappear. For example, chard grows more slowly than choi so you can sow more chard seeds or sow the chard in its own section.

Timing for Southern California

Start a cut-and-come-again bed in all seasons except late spring and summer unless you live close to the beach, where it rarely gets over 80 degrees.

My favorite time to start is at the end of summer or very early in fall, by mid-October. My second favorite time to start is in late January.

If you start in November or December, the plants will grow slowly since the days are so short. If you start at the end of winter, your harvest time will probably be reduced since the longer and warmer days of spring will encourage the plants to bolt (make flowers).

Sowing

Because lettuce and greens seeds are both small, be aware of how deeply you sow. That is, don’t sow deeply.

Here’s how I sow: I sprinkle the seeds so that they’re about a half inch apart, and then I sprinkle compost over the seeds until I can no longer see the seeds. Don’t sprinkle more compost than that or else the little seeds will have trouble germinating.

Lettuce and greens seeds germinate fast, usually within one week. However, lettuce seeds especially cannot dry out during that week of germination so keep the bed showered with water as necessary.

If you have a garden bed with many weed seeds, then be sure to first make a stale seedbed. (More on creating a stale seedbed in this post.)

Alternatively, you can grow your lettuce and greens in a container. One year for Christmas I grew cut-and-come-again lettuce in containers for all of my family such that the plants were ready for their first harvest at the time I presented them as gifts.

If you don’t want to sow seeds, you can buy seedlings and just plant them densely.

Fertilizing

If you begin with fertile soil, either by adding compost, manure, worm castings, or some other fertilizer, then you shouldn’t have to add anything else during the crop’s life. I have never seen a need to do so with my cut-and-come-again plantings in the ground or in containers (with good potting soil).

Harvesting

Start your harvest whenever the leaves are at the size you want to eat them. For me, that’s at four to six inches tall, but there’s nothing wrong with waiting until the leaves are taller.

Cut the leaves off an inch or two above the soil level. If you cut lower than this, you’ll damage the crown of the plant, which is where new leaves form, and the plant might die.

Use scissors or a knife. I prefer a knife — straight blade as opposed to serrated. Lately, I’ve been using an Opinel No. 8.

If there’s dirt on any leaves, dunk them in a bucket of cold water. If the water isn’t cold, the leaves will go limp. You can store them in the fridge if you’re not going to eat them immediately, but make sure they’re dry before putting them into the fridge or they’ll become soggy in there.

After cutting for harvest, the plants will rapidly grow new leaves, and you’ll be able to cut the same patch again in a week or two.

Bolting

You might get three or more harvests from your patch before the plants bolt. All lettuce and greens plants end their lives naturally by sending up a stalk of flowers which ultimately become seed pods. I do not cry at the sight of this. I rejoice in the flowers of various colors as they attract all sorts of bees, syrphid flies and other insects that pollinate our other vegetables and eat pest insects. I leave the flowers until I need the area for other vegetables.

Once the plants bolt they will taste more bitter, however, so you might not want to eat their leaves any longer. I continue to pick some for my chickens, which don’t mind the bitterness.

I also keep an eye on the forming seed pods. Don’t let them dry and burst or you will have new lettuce and greens plants popping up. Then again, you might want that.
