Spinach plants need 3-5 inches between plants, and in a raised bed you can use that same spacing in both directions โ€” no walking rows needed. At the 4-inch midpoint, that's 24 along the bed and 12 across โ€” 288 plants.

Why

Crowding is the most common spacing mistake: closer planting doesn't add yield, it adds shade, disease pressure, and small fruit. When in doubt, use the wider end of the range.

  • Air circulation between mature plants is the cheapest disease prevention there is.
  • Roots spread wider than the plant looks in June โ€” spacing is set for August size.

When this doesn't apply

  • Compact spinach plants can take the tight end of the range; large or vigorous ones want the wide end.
  • Square-foot gardening compresses further than these numbers โ€” it trades yield per plant for yield per bed and needs diligent feeding.
