This step by step diy project is about diy raised garden bed plans. I designed this large U-shaped raised garden bed so you can grow vegetables and flowers in your own backyard. The garden bed is built using 2×10 beams and 2×2 posts. Make sure you don’t buy treated lumber and don’t apply toxic treatments to the lumber, as it will contaminate the soil on the long run. Take a look over the rest of my woodworking plans, if you want to get more building inspiration.
When buying the lumber, you should select the planks with great care, making sure they are straight and without any visible flaws (cracks, knots, twists, decay). Investing in cedar or other weather resistant lumber is a good idea, as it will pay off on the long run. Use a spirit level to plumb and align the components, before inserting the galvanized screws, otherwise the project won’t have a symmetrical look. If you have all the materials and tools required for the project, you could get the job done in about a day. See all my Premium Plans HERE.
