Frequently Asked Questions

How many raised beds do I need to feed a family of 4?

For substantial vegetable production for a family of four, plan on 600–800 square feet of garden space — roughly 19–25 standard 4×8 raised beds. For near self-sufficiency in vegetables, that grows to 1,200–1,600 square feet depending on your season length.

What is the most productive vegetable per square foot?

Tomatoes, zucchini, and green beans consistently produce the most food per square foot. A single tomato plant in a 4-square-foot space can yield 10–20 pounds of fruit. Zucchini is so productive that one or two plants usually feeds a family with surplus.

Does succession planting really reduce how much space I need?

Yes — succession planting (replanting a bed as soon as one crop is harvested) can reduce your total space needs by 25–40%. Instead of leaving beds empty after spring spinach, you follow with summer beans, then plant fall kale in the same beds.
