Cucumber Spacing in a Raised Bed (4x8 Plant Count)
Recommended cucumber spacing and a fast way to estimate how many plants fit in a 4×8 raised bed.
Worked example
Example bed: 4×8 ft, spacing 12". Length=96", width=48". Plants = floor(96/12)×floor(48/12) = 8×4 = 32 plants (grid estimate). If that seems high, increase spacing or plan for row/trellis layout rather than a pure grid.
Why the numbers vary
Cucumbers may be spaced tighter on trellises and wider for sprawling vines. Trellis availability, airflow, and disease pressure (powdery mildew) can push you toward wider spacing.

FAQ
How many cucumber plants in a 4x8 raised bed?
At 12" grid spacing the estimate is 32 plants, but many gardeners use fewer with rows/trellises.
Why does trellising change spacing?
Trellises keep vines vertical, improving airflow and access, which can allow tighter in-row spacing.
Do cucumbers have high yield per plant?
It varies by type and harvest frequency; use ranges as a planning bracket only.
Should I count plants differently for rows?
Yes. A row-based model can be more realistic. This tool provides a simple conservative grid estimate.
