PS - something else I thought of - *against* the idea of using a

all over the flowerbeds too, and probably took about a year or two until
all traces had finally disappeared. *She* was not a happy bunny.

That thought had already occured to me, which was on of the plus
points for the needle gun. Going to get scaffolding for access so a
tarp can be put on the outside/around the work area to contain the
worst of a PW kick back, well in theory.
