There is method in this, as I wanted to save my French Sorrel. This likes a damp shady environment. It goes deliciously with fish. I also scattered some old Sweet Basil seeds in the rest of the bald patches. You never know..
I salvaged a small clump of Lemon Verbina that had also sprouted near to where I plan attacking with Chemical Weapons! A last resort I can tell you. I just can't see any other way of dealing with the Briars that keep overtaking my Greenhouse. I will take a picture of that tomorrow morning as it is totally in shade right now. I am scratched to bits, just clearing a path and broken glass from tree branches falling.
