Winter Bloomsdale Spinach Seed

Regular price $2.79 $2.00 Sale

Winter Bloomsdale Spinach seed is a certified organic open-pollinated/heirloom. It's dark green deeply savoyed leaves are slower growing with a more spreading habit than other varieties. Recommended for early spring and fall plantings because it tolerates temperature extremes better than some hybrids. Ideal for wintering over. Has best spring bounce-back after severe winters in a low tunnel. Resistant to CMV and BM.

About 250+ seed per pack. 94% germination.

Spinach 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 reduce bolting, avoid hot-weather planting, use wider spacing and irrigate or use shade cloth. Plant spinach in a location shielded from western/setting sun.

Optimal soil temps for best, fastest germination 55 - 60°. Emergence takes 12 days at 50°. Spinach seed will not germinate in soil temperatures above 85°.
