Spinach Germination Information

Spinach Seed Germination How to Sow Spinach:

  • Best sown outdoors as soon as the soil can be worked in the spring
  • Sow in succession every 7-10 days until 6 weeks before daytime temperatures are above 75°
  • Sow again in late summer, up to 6 weeks before nighttime lows are below 20°
  • Seed can also be sown indoors at a temperature of 65-68°
  • Indoors, expect germination in 8-10 days
  • To hasten germination, provide cold-moist stratification in the refrigerator for 1 week prior to sowing
  • It is about 30 days from sowing to harvesting
  • When sowing seed outdoors, we recommend a maximum planting depth of 4X the width of the seed

How to Grow Spinach:
Transplanting: Transplant when there are at least two sets of true leaves

Spacing: Thin or transplant so that seedlings are spaced 4-5 inches apart and in rows spaced 15-18 inches apart

Lighting: Site in full sun

Soil: Site rich soil with excellent drainage and as close to a neutral pH as possible. Keep well watered and fertilize prior to planting and again after thinning

Additional Care: Grow as a spring or fall crop, as it is a cool weather and short day crop that suffers in summer

Appearance and Use:

Grown as an edible leafy green for eating raw or cooked. It is an annual that grows to 1 foot tall and 8-10 inches wide. The plants form basal rosettes of the dark green, smooth (or crinkled in the savoy type) foliage. To harvest, cut off the entire plant at the soil line. Do so when the leaves are 6-8 inches long and before the flower stalks form. Spinach is eaten fresh and it can be preserved by canning or freezing
