Using pressure treated wood for vegetable planters? Bad idea?

[CherryStoneTree]

So new to actual beds this year rather than pots. Managed to track down some wood and have been lovingly cutting and painting with cuprinol garden shades to make some raised planters which we’ve filled with soil.

I’ve just read that we shouldn’t use the pressure treated timber as the copper can leach out? The wood is C16 kiln dried pressure treated wood with Tanalith E, which is a copper based wood preservative.

Can I not use the beds? Or will the Cuprinol stop the leach, or is that in itself bad? We’ve filled with new top soil. I’ve read that copier will “just” kill the plants?

I read up about this recently as I’ve just bought a load of wood for beds. Seems to be no evidence of any problem,ms, and I’ve never had a problem in the past either. However if you are worried you could line the beds with plastic sheeting. Personally I’ve not bothered. The risk seems minimal compared to the added hiding places for slugs!!

There may be a higher risk if you’ve painted with Cuprinol on the inside as it is on the surface not pressured into the wood. But I’m just speculating.

Bear in mind that copper is used in organic farming as a fungicide so it isn’t all black and white.

Thanks both, I think we’ll still go ahead and yes the Cuprinol is probably worse! Read that the copper is much better than previous arsenic.
