We have quite a large area of block paving, every year a sort of mossy grass grows between the bricks and every year my husband has spent a long time on his hands and knees systematically scraping it out. He is not able to do it any more anyone got any solutions!?
Take it a bit at a time.
Pour boiling water into the spaces between the bricks and then add the cheapest salt you can find.
Cheaper, less work, and no dangerous chemicals.
My entire front garden is laid to block paving. All I use is 'Pathclear', kills all the weeds and keeps it clear for about 6 months. The weedkiller doesn't appear to 'creep' into the border areas either.
Have a look in today's Mail on Sunday newspaper, they have an advert for an excellent electric tool for cleaning between the bricks, its on my list to buy this week.no more hard work. Or bending down. Looks good.
