Our house faces north, and as such the tarmac drive

I've tried over the years removing the moss that grows

by scraping it off with a spade and blasting it off

with a power hose. Neither of which work really

successfully and are starting to damage the tarmac.



So it looks as if it must be a chemical attack, but

what with? I,m hoping to get to a garden centre next

week, so I'd like some idea of what has worked and

what to avoid if possible.



Many thanks
