πŸ’‘ How Many Plants for a Garden Bed?

Plant count depends on bed area and desired spacing. For a grid layout: plants per row = (bed length Γ· spacing) + 1. Rows = (bed width Γ· spacing) + 1. Total plants = rows Γ— plants per row. For a triangular (staggered) layout, add 15% more plants.

Common spacing: annuals (6–12 inches apart), perennials (12–24 inches), shrubs (24–48 inches), ground cover (6–12 inches). Closer spacing gives faster fill-in but is more expensive. Wider spacing takes 1–2 seasons to fill in but costs less upfront.

A 10 Γ— 8 ft bed with 12-inch spacing: 11 plants per row Γ— 9 rows = 99 plants. That's 6 flats of 18-count annuals. At 6-inch spacing: 21 Γ— 17 = 357 plants.
