Space Spinach


Space Spinach

(37 days) F-1 hybrid. Regularly sells more than 3,500 packets per year. Produces the kind of vigorous big thick wavy mostly smooth slightly savoyed leaves that market growers love and restaurant chefs adore. Relatively long-standing when sown in early spring. Vigorous at all times, it was the quickest to mature from a fall planting. Upright growth results in good clean dark green leaves with a juicy sweet taste. We’ve heard rumors of Space’s intended demise so stock up, don’t Space out! Resistant to DM1,2,3.5,6,8,11,12 and some resistance to CLS. Cold-hardy through at least part of the Maine winter.

Additional Information


Spinacia oleracea

1,400–2,600 seeds/oz. ¼ oz packet sows 30–50 ft; 1 oz plants 120–200 ft.

Culture: Very hardy. Must be planted as soon as the ground can be worked in the spring to avoid early bolting. For fall crop try late July–Aug. sowing; to overwinter, sow late Aug.–Sept. Heavy nitrogen requirements, but avoid applying high-nitrogen fertilizers shortly before harvest to prevent high nitrate levels in the leaves. Pick large leaves often for heavier production.

Smooth-leaved spinach is easier to wash than the semi-savoyed type and is increasingly preferred. Heat, crowding and long day-length (over 14 hours) trigger premature bolting. To retard bolting, avoid hot-weather planting, use wider spacing and irrigate or use shade cloth.

Minimum germination temperature 35°, optimal range 45–65°. Spinach seed will not germinate in soil temperatures above 85°.
