Is Plywood Safe for Raised Beds?
7 Things to Consider
When you are building a raised garden bed, material is often the first consideration. The easiest thing to do, by far, is to use whatever you have on hand.
Almost every homeowner has a scrap wood pile laying around. So, would it be safe to use plywood for your raised beds? Well, that depends.
Plywood is comprised of thin layers of wood, called veneers, sandwiched together to form a rigid board. More layers give you a thicker piece of plywood.
