This is my new garden bed that I got for Christmas. It is just like two other garden beds that I have. It is railroad ties filled with leaves, soil and compost. I love it....so, of course, some do-gooder had to come on my facebook post and tell me how they cause cancer. Well honey, guess what, everything thing does!
The facts are they contain creosote and studies have proven that plants do not take this up by the roots so it is unlikely to cause any harm. Not to mention that mine are really old railroad ties and any creosote has probably already leached out. I never see any black on them or get any on me when I touch them (which is pretty seldom).
So anyway, if you are a do-gooder, you're barking up the wrong tree...so to speak. I plan on putting in at least three more of these beds as the years go on. And you wait and see if we aren't told, later on. that all these metal beds with their plastic linings cause cancer too and then you can bother those people.
Just so you all know, I have never had vegetables grow so well as they do here in these beds. Can't wait to show you what I grow in this one.
