Does anyone know of a spray that will kill lichen?
I have a half acre block, and apart from the house & a couple of small sheds and an area of old farm implements, it is all rock garden. Fascinating place. Been a labour of love for the man that created it but unfortunately he passed away 7 years ago. Now his widow wants the lichen removed from the rocks.
I think it would take too long to do with a pressure cleaner. I sprayed a small area today with glypho for a trial, but I don't think that will work.
The widow says she has some spray that hubby used to use, but if it's been sitting in the shed for 7 years I don't think I want to use it. Also, she's invalid, a bit paranoid and everything is locked up,so I haven't been able to see what it is.
Any ideas?
Here is a pic of the place I found on the net, but that's only a fraction of it.
