  • Materials for garden retaining walls

    We have access to old railroad ties and I was wondering if they are safe to use as retaining walls for my garden. I know they smell terrible but will that affect my plants in any way?

    We've use 'em for years here in Tx.,there just the right height for filling in with dirt(raise beds),and the sticky glue is usually only on the top and not on the sides,so it should be okay,plus they don't rot as quickly as others do.

    Old railroad ties are often loaded with PCB’s. That’s why they smell bad. PCB’s were banned int the 80’s (?) because of links to cancer. I don’t know how readily they leach into the soil, but I wouldn’t be comfortable using them for a vegetable garden.
