Easy to make concrete panels for raised bed gardening. Wet conditions in the spring make raised bed gardening a necessity at my location. Concrete panels cost less than wood and they will not warp or rot over time.
I got the idea for this from a video by "Man about Tools". Here is a link to that video. https://youtu.be/yuSBwFkCiAw
I used cheap latex caulk when making the first two panels, but found it difficult to remove from the mold. I did not use any caulk on later panels and found that it was not needed.
