Can someone please tell me if plants will grow on a frame which has been treated with Cuprinol or some other wood preservative.
Many thanks.

Provided that the treatment solution is dry then it will not harm any plants that you grow up it. The danger time is when the frame is being painted and the solution splashes the leaves of the plants.
