Spinach is a cool season plant that prefers moist, well-drained soil high in nitrogen. Choose a site with full sun to partial shade.
Seeds germinate best if soaked in water prior to planting. Germination rates are greatly reduced if soil temperatures are above 65˚F. Start seeds as early as six weeks before the last frost or as soon as you can work the soil. Sow seeds ½" deep and 1" apart. Seeds will sprout in 6-21 days. Thin seedlings so that mature plants are 4" apart.
Spinach can be planted in succession every two weeks throughout spring and again in late summer for a fall crop. With minimal protection, spinach overwinters in most areas of the U.S.
Harvest when plants have at least six 3-4" long leaves. Harvest by cutting leaves from the outside of plant first to prolong productivity.
Hot temperatures and long days will trigger flowering in spinach. Allow spring crop to flower and set seed. Seed is ready to harvest when the flowers have dried brown and seeds are black. Spinach seeds do not store for extended periods of time. Fresh seed should be used each growing season.
