Spinach Seed

Growing Spinach

Spinach prefers a fertile soil with high organic matter (compost) and a pH range of at least 6.0, but preferably 6.5–7.5. Germinates best in cool soil and can be sown as soon as the ground can be worked. Sowing every 7-10 can ensure a continuous supply. Summer sowing with soil temperatures over 85°F/ 30°C likely won’t germinate well.  Sow in mid-to-late summer for a fall harvest and continue sowing if winters are mild and you can offer some protection in a greenhouse or under reemay/floating row cover. Consistent watering at any time of year helps spinach thrive. Spinach can also be started indoors and transplanted. For baby spinach, sow 3–5 seeds/inch, ½” deep, in rows at least 2" apart. For bunching and full size sow 1-3 seeds/inch in rows 12–18" apart.
