4x4 Raised Bed Peas
A complete plan for soil, plant count, and yield range for peas in a 4x4 raised bed.
Quick answer
For a 4x4 bed at 12" depth: soil ≈ 16 ft³ (≈ 0.593 yd³).
With 3" spacing: 256 peas plants.
Yield range (raised bed): 53.8–161.3 lb (typical ≈ 107.5 lb).
Worked example
Soil: 4×4×(12/12) = 16 ft³ (≈ 0.593 yd³).
Bags: 2 cu ft → ceil(16/2) = 8, 3 cu ft → 6, 1.5 cu ft → 11.
Plants: floor((4×12)/3)×floor((4×12)/3) = 256.
Why these numbers vary
Real results vary by variety, trellising, fertility, watering, temperature, and how aggressively you harvest. Treat this as a planning range—not a promise.
Spacing note
This page uses the dataset spacing (3"). If you plant tighter or wider, switch to Custom spacing in the calculator.
FAQ
How many peas plants fit in a 4x4 raised bed?
Using 3" spacing and a floor grid, you can fit about 256 plants.
Do I need to buy extra soil?
Often yes. Soil settles, especially mixes with compost. Many gardeners buy 5–15% extra.
Is 12 inches of soil depth enough?
For most vegetables it’s a good baseline. Deep-rooted crops may benefit from more depth or looser subsoil.
Does trellising change the spacing?
Yes. Trellised crops can sometimes be spaced tighter. Use Custom spacing if you have a proven system.
Why is yield shown as a range?
Yield depends heavily on variety, climate, fertility, pest pressure, and season length.
