Direct seed in early spring. Sow thickly in wide rows or in beds. Cover lightly (about 1⁄4 inch deep). Plant every one to two weeks to insure a constant harvest.
Choose an area with full sun to partial shade and soil pH of 6.2-6.8. Lettuce is a heavy feeder and prefers a rich, well cultivated soil with good drainage. Some success can be expected even in poor soils using the loose-leaf types. Add plenty of compost or well-rotted manure prior to planting. Benefits from regular feedings with a nitrogen rich fertilizer. Mulching is useful to keep soil cool and reduce weeds.
Harvest when plants are 3-4 inches tall. Simply cut off the leaves above the soil. Under proper conditions the lettuce will regrow and provide a second harvest.
Pests and Diseases:
Protect mesclun mixes from flea beetles by using row covers. Slugs can cause problems with lettuce and can be controlled with slug bait.
Most vegetables, carrot, garlic, onion and radish make the best companions.
Sow seeds in a shallow tray of potting mix and cover lightly. About 8 to 9 grams of seed should be enough for an 11 inch x 21 inch tray. Keep the soil moist but not wet. Seedlings should be grown in full light to keep them from stretching.
Once seedlings have 1 –2 true leaves they are ready for harvest. This can range from 10-20 days depending on the growing conditions and the type of micro green. To harvest cut the seedlings off just above ground level with a sharp knife or scissors. The plants will not regrow, so discard the left over soil and start a new batch.
Damping off can be a problem with microgreens. Be sure and use fresh potting mix with each batch, do not over water and allow air to circulate around the seedlings.
