Lettuce
Sow a few seeds of lettuce very thinly in a line once every three weeks. When the seedlings, which should be protected from birds by netting, are three inches high, thin them out, leaving one foot between each plant. The seedlings that are pulled up can be transplanted or eaten. Transplanted lettuces should be shaded during hot weather and given plenty of water. During dry and hot weather you may water lettuces every day.
