Someone (Krumlink I think) mentioned that he spilt some Used Ferric Chloride on the lawn and the grass wouldn't grow for years after.
I've decided to put the herbicidal properties of copper to good use. I use Sodium persulphate / sodium bisuphate PCB etchant solution. The used solution is a mixture of sodium sulphate (I think) and copper sulphate, the latter I know is harmful to plants.
There was a 25 year old laburnum tree in the back garden that needed removing, these trees are nice but we've already got one but it spreads like a weed.
I chopped it down, drilled loads of holes in the stump and filled the holes with the used solution. It's been a few days and I can't see any signs of regrowth but I think I'll have to wait until spring next if that happens, hopefully it's gone for good.
I've covered it with a bucket, in the hope that it'll stop the rain from washing the etchant away.
One disadvantage might be that copper is anti-fungal so the stump probably won't rot very well.
I've noticed another funny thing: it reacts with the soil, I don't know why. I've test it with chalk and it didn't react (the soil is clay chalk where I live), I tested it with potting compost and it didn't react. Any one know why it fizzes and gives of a horrible gas when mixed with clay?
