Spinach is a nutrient-dense cool-season green that grows fast in spring and fall.

Top Growing Tips

  • Plant as early as soil can be worked (tolerates light frost)
  • Bolts in long days and heat — time plantings carefully
  • Fall plantings often produce better than spring
  • Keep soil consistently moist for tender leaves
  • Malabar spinach is a heat-tolerant alternative for summer

Companion Planting

Good companions: strawberries, peas, beans, brassicas

Avoid planting near: none in particular
