The Q&A Archives: Raised Vegetable Frames

Question: Is there a way to safely use treated lumber for raised vegetable frames?

Answer: If you're concerned about chemicals leaching from the treated lumber you might consider lining the sides of the raised beds with plastic sheeting. Or, you can simply plant root crops 6 or 8 inches way from the sides of the beds. Above ground vegetable plants such as tomatoes, peppers, corn, etc. should be safe near the timbers; plant lettuces, radishes, carrots, etc. towards the center of the bed. Enjoy your garden!
