Growing Tips

  • 1Plant spinach in a spot that gets partial to full sunlight, as it thrives in cooler temperatures.
  • 2Water consistently to keep the soil moist but not waterlogged, as spinach prefers well-drained soil.
  • 3Space plants about 6 inches apart to allow for proper air circulation and growth.
  • 4To manage pests, use row covers to protect young plants and encourage beneficial insects like ladybugs to control aphids naturally.

How to Harvest

  • 1Harvest spinach when the leaves are large enough to eat but before they become tough or bitter, typically when they are about 3-4 inches long.
  • 2Use scissors or a sharp knife to cut the outer leaves about an inch above the base, leaving the center intact to encourage regrowth.
  • 3Avoid pulling the entire plant to allow for multiple harvests throughout the growing season.

Step 5

Saving Seeds

How to Save Seeds

Saving seeds from your spinach plant is easy and rewarding! Simply let a few healthy spinach plants bolt (flower and go to seed) instead of harvesting all the leaves. Once the flowers dry out and the seeds turn brown, gently shake or rub the seed heads to collect the seeds. Spread them out to dry for a few days in a cool, dry place, then store them in a labeled envelope or jar in a cool, dark spot until next season. You’ve got this—saving seeds is a simple way to keep your garden growing year after year!
