Raised beds require an initial investment, but the advantages outweigh the costs. Soil in raised beds is rarely walked on, preventing soil compaction and weed contamination. Raised beds also allow better soil control, as they can be filled with the preferred soil for the year's crop. Plants in raised beds get more sun and air circulation that traditional garden and soil remains warm throughout the season. Build a raised planter bed with untreated wood boards.
Find an area in the yard that receives plenty of sunlight. Decide the size and shape of the raised bed. Allow for room to walk around the bed and maintain it.
Cut wood boards to the length and width required for your designed bed. Stand the boards up on their sides and attach the edges of the boards together using metal braces. Ensure the edges are 12 to 16 inches high and the metal braces are secure enough to hold soil inside.
Place the wooden box in the garden. Fill it with soil mix and add compost. Test the soil with a pH tester from your local garden center to ensure the soil is the right acidity for your selected plants.
