Plant Development and Care
Lettuce plants will germinate in cool soils (32° F to 40° F) and grow quickly in these conditions.
Lettuce should not be subjected to wet, dry, wet, dry soil cycles. Keep soil moist, but not soggy.
Pick when greens are young, tender and mild flavored. Begin cutting greens when they are about 2" tall.
Head lettuce is more difficult to grow than leaf lettuce varieties. It has very particular climate, soil and cultural requirement for successful growth.
