Frequently asked questions
- How many plants fit in a garden bed?
- Divide the bed area (ft²) by the spacing area (plant spacing in ft, squared). For 12-inch spacing, each plant occupies 1 sq ft; an 80 sq ft bed holds 80 plants.
- What is the standard plant spacing?
- Spacing depends on the plant type: lettuce 6–8 in, tomatoes 24–36 in, peppers 18 in. Always check the seed packet or plant tag for recommended spacing.
