Is it still dangerous to use pressure treated lumber for my garden beds even though arsenic has been banned since 2004?

It appears from my quick google search that the verdict is still out. Some say minimum gets into the soil, others say none. I try to be as organic as I can be, so I'd vote no. Mine are pine. Coming into their fourth year and show no rotting. If they last 10-15 years that will be sufficient for me, as I'll be too old to care.

Cedar might be a good substitute.

I've read and been told NO.
Or, Ponder this : Wood is treated with bad butt chemicals. Wood is porus. Vege roots grow against and into wood. Roots pick up chemicals, that travel to all parts of plant.

Cedar lasts a long time !👍

I think I would be cautious using it for a vegetable bed. Especially if it is new lumber. Older lumber might have had most of the chemicals washed away. But I think it would be OK for a flower bed. For a veggie garden, I would buy something from a garden center and ask them if it is OK or not - they should be able to tell you that.

In Canada, it is no longer legal to treat lumber with any arsenic derivative. As such, for some time now, our lumber products have been treated with a copper solution only. In the US? No idea. "Everything" is chemical, even what I am thinking and writing now, could not be accomplished without "chemicals" driving my neurons and dendrites in my feeble brain, and "chemicals" making my eyes, and typing finger all work. On the list of harmful "chemicals", copper is way down the list. In fact, a natural element found in soil, most fertilizers, and most foods, and a body requirement. If one can afford Cedar, go for it! If you can't afford that option, I see nothing wrong with a copper infused solution for treated spruce or fir lumber, in vegetable raised beds as well, and I use it for same. If there was a danger to gardeners, the plants would die off and give a major alarm! They don't die off. Note: Here, there is a small tag stapled to every piece of treated lumber. Easy to identify the manufacturer. Google and ask them. Cheers!

If all you are growing is flowers, it's okay to use the new pressure treated lumber. If you are growing an organic garden then, no, it is not allowed or you could not be considered organic.

I have used the pressure treated lumber but am making my newer beds using cedar. If redwood is available and affordable, that would be my best choice.
