The leaves are tougher and more bitter than than head lettuce, but that makes them great in a stew or stir fry.
Stem lettuce grows best in cooler summers. So if it's hot, give them some shade - especially in the afternoon sun.
Pests and diseases won't be much of a problem for stem lettuce. But watch out for snails in those first weeks: they do like the young plants.
You can harvest the leaves after 5 weeks or so. Harvest the stem when it's about 5 cm in diameter. Don’t leave it too long: it can get tough, dry, and sometimes even hollow.
Extra info: You can grow stem lettuce in early March under glass or in a cold greenhouse. Not on the windowsill, that’s too hot. You can also grow them in August in a cold greenhouse.
Step-by-step sowing and growing instructions are in the Planty Gardening app.
But: you grow this lettuce mainly for the stems of course. Harvest them when they're 25 - 45 cm tall and 3 - 5 cm thick. Peel first before eating.
Try the stem raw in a salad, or enjoy cooked stems in a stew, stir fry or on its own briefly boiled. When cooked, the stems look kind of like asparagus. That's why it's sometimes called asparagus lettuce.
