It does not germinate well in hot weather. If planted in late spring as hot weather approaches, the plant will quickly throw up a flower stalk and go to seed after only a few leaves develop.
All spinach is harvested mechanically.
Spacing is often determined by the demands of the harvesting equipment and the width of the cutter on the harvester. Final stands should be 7 to 8 plants per foot, although 10 plants per foot is acceptable. Thinner populations will enhance control of foliar diseases because of better air circulation. The plants will also be thicker and blockier. Spinach responds to lime.
