What kind of wood should be used for raised beds?

What Kind of Wood to Use? In most cases, cedar is the best wood to use for garden beds because cedar is naturally rot resistant. Western red cedar is commonly used, but Vermont white cedar, Port Orford (yellow) cedar and Juniper are also high-quality choices for outdoor construction projects.

How deep should a raised bed garden be?

A raised bed does not have to be very deep to be effective. Eight to 12 inches is usually adequate. If drainage is a problem, or if the plants you are growing prefer drier soil, the bed could be taller and filled with a porous growing medium. Vegetable beds should be 12 to 18 inches deep.

What do you put in the bottom of a raised garden bed?

The bottom of a raised garden bed should be a layer of grass clippings, leaves, wood chips, straw, and other organic material. The cardboard should be placed on top of that layer. The organic material will turn into compost, while the cardboard will prevent weeds.

Should I line my raised garden bed with plastic?

You can line your raised bed to make it more durable and to prevent toxics from leaching into the soil. For lining, use landscape fabric found at garden supply stores or cloth fabric from clothing. Avoid non-porous plastic, as it can retain too much water and discourage beneficial insects and worms.

Should I put rocks in the bottom of my raised garden bed?

Building raised beds is well worth the effort. Raised beds allow you to overcome problems such as poor, rocky soil, waterlogged areas and people walking through your gardens. While raised beds drain better than in-ground beds, adding rocks to the bottom of the bed improves drainage even further.
