To keep your plants safe and edible, avoid using older wood to construct raised beds, as it might contain harmful chemicals.

Is pressure treated OK for raised beds?

Yes, the “new” pressure treated wood is safe for use for raised garden frames… with a few precautions! Up until 2003, the most common preservative used for pressure treated wood was chromated copper arsenate (CCA), a compound using arsenic as its primary rot protectant.

Can you use pressure treated wood for compost?

Pressure-treated lumber’s resistance to rot and decay makes it a favorite for garden structures, such as raised beds and compost bins. New alternatives to CCA-treated wood that use formulations that fight decay, but without using arsenic, are now available for use in residential construction.

Can you make a compost bin out of pressure treated wood?

Can pressure treated wood be composted?

Pressure treated wood (often recognizible by its’ greenish colour) has been shown to leach arsenic into the soil when used for making kids playground equipment, compost bins and raised beds.

Can treated lumber be used in a vegetable garden?

Yes! Pressure-treated wood is safe for vegetable garden beds but with some precautions.

Neither result is desirable, so Cooper does not consider pressure-treated wood suitable for making compost bins, although he doesn’t object to using it in gardens. Finished compost has a near-neutral pH, so adding compost to CCA-framed beds isn’t a problem.

Should you use modern treated lumber in a raised bed garden?
