Raised Bed Gardening

Question

I have a lot of old weathered, grey non-sticky railroad ties. Is there a way I can use them to build raised beds? Maybe by lining them with cedar?

Answer 1

Yes, you can use them. Most people line them with plastic to keep any chemicals out of the bed that could be harmful, but it sounds like, if they are grey, the creosote has washed away and most of the chemicals have already been leached away.
