Question re: Tanalised timber

Mark Hegarty asked 13 years ago

I hear a lot about not using tanalised timber in raised beds where vegetables will be growing. My question is, is it safe to use tanalised timber for raised vegetable beds and if not can I make it safe by seperating it from the soil with polythene or another non permeable membrane? Thanks

Treated timber has some quite toxic chemicals, otherwise it would not prevent rot. But you might consider not using any timber and saving the trouble. Polythene is not aqequate.

By all means raise the bed with extra soil from paths along the sides, as was the traditional way in Ireland… no need for timber!
