Can You Use Treated Wood for Gardening?

Posted 15 September 2022 6:22 PM by ProWood

Whether or not to use treated lumber to build your garden bed/planter is a controversial topic. Overall, it depends on the type of chemical used to treat the lumber. Many manufacturers use a ACQ or CCA solution, which contains arsenic (ACQ did until 2003, but now contains a high level of copper instead). This can be toxic if ingested and is not recommended to use to grow food. However, ProWood lumber is SCS-certified and uses an environmentally-friendly treatment of MCA (micronized copper azole). Our unique solution is a safer option for plants and animals when leaching occurs.

 

Our Treating Process

Our process used to treat ProWood lumber is the first to gain Environmentally Preferable Product (EPP) status as certified by Scientific Certification Systems (SCS). Meaning, our product has a smaller impact on human health and the environment when compared to other products that serve the same purpose. Additionally, ProWood has earned a NGBS Green Certification and GREENGUARD Gold Certification for using clean, green products for internal use, such as residential and commercial buildings.

What does that mean for you? 

ProWood is safe for the environment, people, and pets when it comes in contact with them (when used as directed). ProWood is clean, odorless, non-staining, and safe to work with and handle. The preservative injected reacts with the wood to form an insoluble complex that won't evaporate or vaporize. Also, its built-in protection is non-irritating for dermal contact with children, adults, animals and plants. We have carefully and exhaustively studied the minute amounts of preservative released during a ProWood structure's serviceable lifetime.

 

Benefits of Our Treated Lumber

Using MCA-treated lumber can be responsible for boosting the longevity of your garden projects. Benefits of using ProWood treated lumber include:


  • Reduce rate of rot and corrosion

  • Less toxic to plants and animals

  • Holds its color longer than untreated lumber


Our MCA- preservative is less toxic to the environment, animals, and humans than other preservative solutions. It penetrates deep into the wood fibers for long-lasting color and performance so you can focus more on your flowers, fruits, and vegetables. If you’re planning to garden every year, then using a treated bed is recommended for less maintenance. If not, you may need to replace your untreated structure once a year due to rot and decay from use.
