Can I plant lettuce in fall to come up in spring?

Yes, gardeners in northern climates can harvest early-spring lettuce—as well as spinach, kale, garlic, and parsley—if it’s planted just before the cold weather arrives in fall. Protect the young plants with a cold frame or thick mulch through the winter, then remove the protection when soil temperature in your area reaches 40 degrees F. Water the new plants well in spring.
