Raised garden beds are easier to manage and harvest from, as you don't have to bend or kneel to work on the plants. The materials used to create the bed are not limited to wood but can include a common material like corrugated metal. It’s strong and able to hold the weight of the soil. Sheets are usually galvanized and therefore resistant to the weather and moist soil.
Things You'll Need
18-inch panels corrugated metal
Wooden stakes
String
Measuring tape
36-inch wooden stakes
Mallet
Sand
Rake
Measure out a plot for your raised garden. Plan to make it no more than 48 inches wide or long so that you can reach into the bed from any side. Mark the area with stakes and string tied between them. Measure from corner to corner to make sure the garden is square.
Set one section of the corrugated metal along the marked edge of your plot. Pound stakes into the ground with a mallet until they are just level with the top of the panel. Place one stake every 12 inches, alternating between the inside and the outside to hold the metal straight. Repeat for the other three sides.
Fill the bottom 10 inches of the planter with clean sand. This will provide good drainage for the soil on top. Level it out with a garden rake.
Fill the rest of the space with topsoil mixed with shredded peat moss and perlite to improve the moisture retention of the raised bed. Use a ratio of five parts topsoil to one part peat moss and one part perlite.
Sprinkle the soil in the corrugated metal planter with your garden hose to help it settle. Add more soil if necessary to bring it to within an inch of the top of the metal sides.
Tips & Warnings
Corrugated panels can be cut using heavy tin snips or a circular saw with a metal blade. If using the latter, be sure to wear ear protection. Cutting metal panels can be deafening.
