Question by D L: using railroad ties for a raised garden bed?
looking for feedback on using railroad ties for a raised garden bed. I love the rustic look and plus you can get them very cheap, and they will last for a long time. What are your thoughts on using them for garden? I do have a concern about the cresole used, will it harm the vegtables that I grow in it?
