Spinacia oleracea ( Nordic IV Spinach )

Nordic IV is generally ready for harvest 45 days after sowing. The leaves are smooth and dark green, and thick. Erect growth habit. Resistant to races 1, 2, 3, and 4 of downy mildew. Spinach leaves may be crinkled as with the savoy leaf, or flat. Spinach thrives in cold weather as warm weather causes it to bolt. Ideal temperature is between 50 and 60 degrees F, it is traditionally a winter crop in the South and an early spring or late summer crop elsewhere. Traditionally spinach is planted about 4 weeks before the date of your average last frost. Because the season is short, (only 60 days) it can be grown just about anywhere. Be sure to keep weeds at bay, as spinach does not do well in competition with them. Spinach is usually ready for harvest about 40 to 50 days after planting.
