Why this page exists

Raised bed listings on Amazon and in garden centers rarely explain the tradeoffs clearly. The material you choose determines how long the bed lasts, how it handles heat and cold, and whether you'll be replacing it in three years — and that matters more than brand.

This page explains galvanized metal vs cedar vs fabric beds, the minimum depth for different crops, how to calculate soil volume, and how drainage works in raised beds vs in-ground gardening.
