If you are getting ready to build raised garden beds to have them ready for spring planting or planning to wait till spring and then build them, this article may help you decide which material to use when building them. A lot of people use wood and there are a couple of woods that are more rot resistant than others like cedar and redwood.
Some folks use pressure treated wood and I know a lot of people refuse to have it in their gardens but according to this article “Pressure-treated wood is treated with alkaline copper quaternary, which the EPA considers safe for food crops, but you may still want to line your beds with weed barrier fabric to avoid the soil’s coming into contact with the wood.”
