Certainly 1 has to apply for Planning Permission/Building Regs. to alter a driveway, which means that proper advice is given regarding run-off to avoid flooding. Especially when people have paved over front gardens for parking. I got rid of lawn 30 years ago, we put that black liner down B4 adding gravel, however I wouldn't bother with the liner if we had other areas to do
because it still requires weeding
I did try camomile - the pricest mistake I've made thus far
and I didn't like the smell
DH does touch that weed that climbs everywhere with a killer ......... it has lovely white flowers if it gets away
. Most other 'weeds' are either tolerated or pulled for the compost. There is 1 here that is prolific and has white flowers which the hover flies love. Off to do a search .......
