I will show you how to build an inexpensive raised bed garden box

As I mention in the book, you need to think about building a raised bed garden box. Once you have made all your preliminary work on-site selection and determining how many beds you need. Your next goal is the size and height of the raised beds. You can view and download my drawings at the end of the text below. Note: The drawings are for demonstration purposes only and not an offer or raised bed construction method.

Why choose to use pre-built fencing.

  • (3) 6′ x 8′ pre-built redwood or cedar fence panels make (2) 30″ 4′ x 8′ beds.
  • Panels are lightweight and sturdy
  • (1) a person can move and assemble the bed(s)
  • Easily disassembled and reassembled in another site
  • Last for years
  • Inexpensive compared cinder block, planks,
  • Prevents plants from over water due to superior drainage
  • Build off-site, transported and assembled on-site
  • Easy to transport due to size and weight considerations

Build List

Use of non-toxic building materials for the process of building a raised garden box. I have built raised beds using cinder blocks, untreated wood fencing, straw, and earth mounds. Materials like plastic or chemically treated lumber or other such materials, I don’t use. I cannot rely on manufacturers of plastic or chemically treated lumber to have my best interests at heart. Let not those who would profit from you, dictate your choices.

Below is the least expensive raised bed. It is also the easiest to build.

The fencing is from a big box store. The bed is between 24″ – 30″ in high, 4 feet wide, and 8 feet long. Each fencing piece should have (3) 2″x 4″x 8′ attaching the vertical slats. If the fence has (2)  2″x 4″x 8′ already attached, you will need to add a 2″x 4″x 8′. In addition to purchasing the (3) pieces of 6′ x 8′ fence, which will produce (2) 30″ x 4′ x 8′ planter boxes.

You will need to complete this process three times. Download the pdf showing the steps at the end of the text below. Accuracy helps, but it is not mandatory. The bed design is to allow the greatest flexibility when placing the bed on its site. You don’t need to have a completely flat spot to place your assembled bed frame.

The raised beds will remain flexible, easy to assemble, and the least expensive I have built.

Building Raised Bed Garden Box List of Materials

  • (3) 2″ x4″ x 8′ long redwood or cedar boards.

  • pry bar (to remove middle 2″x4″x8′ on the fence)
  • drill with Phillip style bit (for all-weather screws to attach the vertical slats to the 2″x4″x8′)
