Growing instructions
CULTURE: Spinach grows in a wide range of soils if moist and fertile, but is sensitive to acidity; pH should be at least 6.0, preferably 6.5-7.5.
SOWING DATES: Spinach germinates best in cool soil. Begin sowing in early spring as soon as the ground can be worked. Summer sowing in soil over 85°F (30°C) risks low or erratic germination. If sowing has to be done during warmer weather, irrigating can help cool the soil and improve germination. Sow in mid to late summer for a fall harvest. Spinach can also be planted from late summer until freeze-up in protected structures for fall, winter, and spring harvest. Using floating row covers offers additional winter protection.
