Our backyard is adjacent to a wooded area. There are lots of groundhogs that eat any vegetables we plant. I figured a raised bed might possibly stop them. This is built out of pressure treated lumber, and stained with two coats of an exterior stain. The inside bottom of the whole box is covered with chicken wire, and I’m probably going to run a piece of chicken wire around the top of the unit too (wrapped around the posts, like a fence). The thing is just under 2’ high, and is a 4’ x 3’ footprint. Total cost for all the material, including the four solar light post caps, was about $105. I filled the bottom half of the box with some miscellaneous dirt and previously ripped up sod from around my yard. The top half was filled with about $40 in bagged soil and peat moss. So all in about $150. Not too bad. This particular back corner of our house isn’t used much and it isn’t the prettiest spot (you can see the A/C condenser), but it gets the best light, so presumably the best for vegetables.
The one concern I had was possible leaching of the pressure treated chemicals from the wood into the dirt, and therefore into the plants. But I couldn’t find any articles or info online that would lead me to believe this is a problem in this instance. I wouldn’t want to suck the juice out of a fresh piece of pressure treated lumber. But given the minimal amount of chemicals that might possibly makes its way into the dirt then into the roots and ultimately the vegetables, I’m not concerned.
