raised wooden veg beds
I've just bought two raised wooden beds, described in the garden centre as 'veg beds' (to prevent dogs getting to them, and to help my aching back!)
Should I line them with anything? I presume they're made out of tannelised timber (if thats the right word). Is there anything in the wood that could contaminate the veg?
Thinking of using black plastic sacks or compost bags? Is it worth it?
