What is Pressure Treated Lumber
Pressure treated lumber is a type of wood that has been specially processed to make it resistant to decay and insect damage. It is commonly used in outdoor construction projects, including decks, fences, and garden beds. The process of pressure treating involves placing the lumber in a treatment chamber and then injecting it with chemicals under high pressure. This ensures that the chemicals penetrate deep into the wood, providing long-lasting protection.
The main purpose of pressure treating lumber is to extend its lifespan by preventing rot and repelling insects. This can be particularly important in vegetable gardens, where the constant moisture and exposure to soil can cause untreated wood to deteriorate quickly. By using pressure treated lumber, gardeners can build structures that will have a longer lifespan and require less maintenance.
However, it is important to note that traditional pressure treated lumber contains chemicals such as copper, chromium, and arsenic. The use of these chemicals has raised concerns about their potential leaching into the soil and contaminating vegetables. Arsenic, in particular, has been linked to serious health risks when ingested in high amounts.
In recent years, Home Depot has taken steps to address these concerns and offer safer options for customers. They now offer a line of pressure treated lumber that contains alternative chemicals such as copper-based compounds instead of arsenic.
These alternative treatments are considered safer for use in vegetable gardens because they are less likely to leach harmful substances into the soil. Additionally, Home Depot provides information on their website about the safety precautions that should be followed when using any type of pressure treated lumber.
While Home Depot’s efforts are commendable, it is still important for gardeners to understand the specific risks associated with pressure treated lumber in vegetable gardens.

The Dangers of Traditional Pressure Treated Lumber
Traditional pressure treated lumber poses significant dangers due to chemical leaching and contamination risks. When pressure treated lumber first emerged in the 1970s, it was primarily made using a compound called chromated copper arsenate (CCA). Although CCA has been phased out in recent years due to its toxicity, other chemicals have replaced it that still present concerns for vegetable gardens.
One of the main dangers of traditional pressure treated lumber is chemical leaching. Chemicals used in the treatment process can gradually leach into the soil and water, thereby potentially contaminating nearby plants. This can be particularly problematic in vegetable gardens where fruits and vegetables are grown for consumption.
The most common chemical used to treat pressure treated lumber today is alkaline copper quat (ACQ), which contains copper and a fungicide. While ACQ is less toxic than CCA, it can still pose risks if consumed or directly exposed to skin. In addition, ACQ-treated wood should not be burned or used for food preparation surfaces.
To address the risks associated with traditional pressure treated lumber, some precautions can be taken. Firstly, it is recommended to use a heavy-duty plastic liner between the soil and any pressure treated lumber used in raised beds or structures. This can help prevent direct contact between the chemicals and the soil used for growing edibles.
Furthermore, when handling traditional pressure treated lumber, it is important to wear protective gloves, long sleeves, and safety glasses to minimize direct exposure to the chemicals. Regular handwashing is also vital after working with this type of wood.
