Sowing: It’s recommended that you direct sow your seeds outdoors. Plant as soon as soil can be worked. If starting indoors, start seeds in trays 3 weeks before transplanting outside. Seeds need light to germinate, so do not cover them with too much soil.
Transplanting: Harden off your lettuce for 3 days before planting outside. Dig a small hole, and cover the roots and the bottom part of the stem with soil. Roots are shallow, so be careful not to disturb the beds once they are planted.
Soil Preference: Cool, loose soil. The temperature needs to be below 70 degrees for the seeds to germinate properly.
Other Tips: Keep soil moist, but not soggy. Lettuce needs direct sun, but over heating can cause it to wilt, or prematurely bolt.
When harvesting, use scissors to cut what you need, and you will get growth for a few more weeks. Use leaves before they get too big, as they tend to get bitter the bigger they are.
