I tried adding on to another thread but realized I should really start a new one.
The area where we want to build a veggie garden is on what used to be a flower bed. It's very over grown and has some old railroad ties around the edges. How much dirt will I have to be removed to get rid of the contamination from the old ties. Is it an issue? How do I keep the old plants from growing back. There are some freakishly persistant small trees in that bed.
We plan to build raised beds and fill them from our compost heap. I know that part of the plan needs research but the initial clearing is what has been keeping me from this project for years.
Any suggestions? My neighbors and I have lots of trees so this area is one of the few spots that I think will get enough sun.
It's likely got creosote, there's warnings all over about not using those for edible plants. 6" of so of dirt around it will be contaminated. But you're putting in raised beds there, so maybe you can just cover over it with a barrier between if you can add enough soil to sustain your plants' roots
