My friend and I want to build a box garden but are afraid that the wood will rot. Right? I thought maybe we could put plastic on the bottom and sides, staple gun it, and poke a few holes in it so it will drain. But I really have NO idea about making garden boxes. I also don't know if the bottom piece needs holes in it to drain or not. Any help would be great.

Keep in mind that you can make your planting boxes as big or small as your space or needs allow. In addition, when using wood, hardwoods tend to work best and last longer. Depending on its size, it may not require drainage holes. There is no need to place a bottom in it unless you’re planning to make a planter box that can be moved around or placed in a windowsill. Then, drainage will be important. Plastic liners can be purchased or you can do as you suggested, but make sure that there are adequate drainage holes.
