I need to build another raised bed and a friend gave me some really old railroad ties to use. I bet these things are over a decade old. Is there really that much risk in the Creosote leaking into my soil and into the vegetables? I keep reading mixed opinions about it.

I've always been taught to avoid them, as well as treated lumber, when making raise bed gardens.

Dunno. The opinions are mixed of course. Question is, if you're going to use a garden to feed yourself and your family, are you willing to bet your life and their lives on the question?

Well I'd say betting your LIVES is a bit much, but the possibility of getting sick is there, for sure. I think if you don't see creosote on the beams themselves then they are probably alright. If it were me though, I'd line the inside of the beams with plastic anyways just to keep them from touching the soil I'm using to grow with.

I'd say avoid them. I've seen railroad ties that are over 100 years old and they look like they were made yesterday. Creosote is pretty evil stuff and those ties have lots of it in them. You could probably saw off the outer layer - I'm not sure how deep in the stuff goes. However, that would get rid of the preservative element that the creosote provides.

While I've never cut one... I'm pretty sure you'd have to cut the majority of the wood off to get anything resembling real clean wood.

Have you thought about ceder logs/posts/rough-cut lumber?

Opted for cinder blocks. Read a bunch tonight. Always thought it was a no-no and most opinions seem to agree. "Might be ok, but not worth the risk."

Going to use the ties for a raised area for the kiddos to play in.

I would avoid using the ties...the creosote does leach out. I had a pond tested and it was found to have traces of phenols and polycyclic aromatic hydrocarbons in it....the only identifiable source present were the railroad ties that I had 30 feet from the pond.

the advice that it isn't worth the risk is probably sound, but we've been doing it for years & haven't had any side effects

we always used them for flower beds and I never noticed any degradation of the flowers...
I to grew up playing in sand boxes made from creosote ties...no tumors here just remember some vicious splinters...my guess after 25 years in the food business, all the poison in our food supply...that would be a minimal concern...I might line it with plastic if I had enough left over...

DUde, don't line it with plastic, that ruins the advantages to drainage that raised beds provide.

It might be pricey, but consider using composite deck boards for your planks. THey're sturdy, impervious to weather, and they don't leach anything worth considering.

Just do the sides only, where the ties contact the soil. The bottom can stay open.

and asphalt doesn't leach into the water table either, so all the roads in the country have nothing to do with water pollution....

Creosote and asphalt are really quite different.
