Can tanalise preservatives in wood contaminate soil?
Devon,
United Kingdom 
I have a Rhodo.yakushimanum in a wooden container. Could the tanalise preservative in the wood contaminate the soil and poison the shrub?

Hopefully not, i have used plenty of treated tubs in the past. But if you want to treat a wooden container use one of the water-based/boron treatments, they are much less toxic! (tho will probably not last as long) or line the tub with plastic (with holes for drainage) to avoid contact with the preservative.
