Q.Can I Use Bitumen Paint To Preserve Wood Where Vegetables Are To Be Grown?
I have new raised beds made from pressure treated sleepers and want to give the wood additional preservation treatment before I fill with soil/compost. Can I use a bitumen paint such as Blackjack where edible plants are to be grown. Thanks

As long as everything has time to cure, I don't see this being an issue. If it does become a doubt, then you could use alternative materials:
