Zucchini Spacing in a Raised Bed (Big Plants, Big Range)
Zucchini needs room. Use spacing to estimate how many plants fit and an approximate yield range.
Worked example
Example: 4×8 ft bed at 24" spacing. Length=96", width=48". Plants=floor(96/24)×floor(48/24)=4×2=8 plants. If per-plant yield is 8–25 lb, bed range ≈ 64–200 lb (estimate).
Why the numbers vary
Zucchini yields can be enormous if harvested frequently, but pests (squash vine borer), disease, and crowding can collapse yields quickly.

FAQ
Is 24 inches enough for zucchini?
Sometimes. Many gardeners use 24–36 inches or mound spacing, especially without trellising.
Why does zucchini yield vary so much?
Harvest frequency, pollination, pests, and disease can change output dramatically.
Will a greenhouse increase zucchini yield?
It might, but humidity can increase disease pressure. Use the greenhouse factor only if it matches your conditions.
Should I give zucchini more space than the recommendation?
If you’re growing large bush types or you want easier harvesting, wider spacing helps airflow and reduces powdery mildew risk.
