Can ProWood ACQ treated wood be used in gardening?
Yes. Treated wood can be used to construct raised vegetable gardens and flowerbeds. Previously, CCA (Chromated Copper Arsenate) had been used as a reliable wood preservative. More recently, treated wood manufacturers, including UFP, have made a transition to newer preservatives, including ACQ (Alkaline Copper Quaternary.) Several studies have shown that plants grown in CCA raised beds do not contain higher than normal levels of the preservative chemicals. We believe the same is true for ACQ raised beds. In addition, the components of ACQ are known to be non-carcinogenic.
