It's old, I suspect dumped by a neighbor. He told me a pole was hit in front of his house some years ago, and then we uncovered this thing. so there is no way to know what it was treated with.
What do you
think of the plan below? I don't want to poison my family, but it also sounds like the stuff may not enter the things we eat as easily as I initially thought.
-remove the pole chunk by chainsawing it in half and getting it to the dump
- remove the soil immediately below/around it (a few cubic feet worth)
-Mulch the area with good
compost
-plant something that's not food that can grow there and then be disposed of (sunflowers?), perhaps repeating this for a few years, perhaps trying mushrooms when I'm brave
enough
-continue with plan to plant 2 pawpaws and their guild about 10 feet away
