Bloomsdale Spinach Seed Organic

Regular price $2.59 $2.00 Sale

Our Bloomsdale Spinach seed is certified organic and open pollinated heirloom. (42 days). The standard crinkly leaved spinach. Very good cold soil emergence. Much better in fall than in spring when it bolts in the heat. I once planted a 3'x5' bed and harvested 15 pounds in the third picking! It may not sound like a lot but it fill a large construction trash bag! It grows best in the fall because its quite cold hardy and will overwinter in WI under a low tunnel. Spinach has high amounts of vitamins A and C, and iron.


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 is 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°.
