Lettuce in the US

Now, sowing times for lettuce, they really depend on your USDA zone, so check the app for your local climate. For zones 5-7, you're looking at March through May for a spring crop, then August and September for a fall harvest. Further south in zones 9-10, you can even get going in January and February. Pop the seeds about a quarter inch deep, maybe half a centimeter, then cover lightly. I always sow a small batch every couple of weeks, you know, for a continuous harvest, a bit of succession planting. They usually take about 50 days to be ready.

If you started your seeds indoors or in a cold frame, you'll want to prick those seedlings out when they're big enough to handle. Give them their own little pots, then harden them off for a week or two before planting out. Space them about 6 to 12 inches apart, depending on the type you're growing. Lettuce does great in containers too, or nestled between your carrots, radishes, or even strawberries. Good companions, those.
