For summer varieties of spinach sow in late spring, and protect with fleece if there is danger of frost. For winter varieties sow at the end of the summer. Sow the spinach seeds in situ in drills 30cm apart, and thin to 15cm between plants. Alternatively sow in modules and transplant to final spacing.
Spinach growing calendar
Spinach (spinacia oleracea) was likely to be first cultivated in central and southwestern Asia; spinacia tetranda, the wild form of spinach, is still gathered as a wild edible green in Anatolia. Spinach is dense in vitamins and minerals, low in calories and versatile in cooking. It belongs to the goosefoot family and is closely related to beetroots and chard.
