Second Plantings
Fortunately, in most climates, the growing season does not end after your first round of crops has matured. Some plants, usually those that are slower to mature, will continue to produce delicious fruits and vegetables all season; others will reach maturity faster but only produce once or twice. You can do second plantings to increase the amount of produce you harvest. Spring-loving crops will exhaust themselves sooner and can be replaced with more cold-tolerant or “hardy” varieties. For example, the bed you use to plant lettuce in the spring could house kale in the fall. You could even use the same bed for one variety of lettuce in the spring and a hardier variety in the fall.For more advice on second plantings and second harvests see:
