Recently used Pathclear on passion flower and valerian coming up on edges

Anyone else had poor results from Pathclear?


Yeah, Pathclear is useless. They changed the formulation as it used to
contain paraquat (which was really effective) but that is considered too
toxic now.

So I use sodium chlorate on paths/driveways now. That kills everything.
Except moss !! But for that you don't need an oxidising agent like
sodium chlorate, you need a reducing agent like ferrous sulphate.
