Structures are the biggest purchases most gardeners make, and the ones that fail most often from the wrong climate fit. A greenhouse that is fine in Georgia can buckle under a Minnesota snow load, and a raised bed that suits a patio can be too shallow for carrots.
Each guide below compares models by the things that decide whether a structure lasts: panel and frame material, snow and wind ratings, depth and size, and the USDA zones it suits.

How to Choose
- Start with your climate. Find your USDA zone, then check snow and wind ratings before size.
- Measure the site first. Leave room around greenhouses and sheds for doors, vents and maintenance.
- Match depth to crops. Most vegetables need at least 11 to 12 inches of soil; root crops more.
- Plan the base. Level ground or a frame base prevents warped doors and panels.
