Luckylegs9 It depends what sort of leaves they are. Some break down better than others.
I have the same problem. When I first moved here (at the right-angle of an L-shaped cul-de-sac) I suggested to the neighbours that we shared in buying a top-of-the-range leaf vac but they weren't interested. I realised why when it seemed that I was the only one who got everybody's leaves due to being on the right-angle. The worst leaves are from Plane trees, of which there are 3 at one side of my house on a council-owned swathe of grass, and some of the leaves are the size of dinner plates.
One year when I was ill I just left the leaves where they fell but they wrecked grass and plants.
The trees are on council owned land but the council don't care. I battle with them via email every year. Sometimes they send a truck down with a whooshy-brush thing that sweeps and sucks up, but they never give advance notice and sometimes it comes at 7 am and people's cars are parked outside and it can't get round. I have seen the driver check out the situation and just reverse out and park up and have a fag!
The leaves are getting slimy now and mushed down and as the road slopes, our cars skid and can't grip the tarmac.
I worry about falling over. Last year the leaves were ankle-deep - dry on the top and slimy underneath, so treacherous. I also have 3 trees opposite my house which are ash and the leaves that fall on the grass beneath just break down, but those that completely cover my car like an Army camouflage net, and those that fall on the ground, just go soggy.
It costs me money every year as I am now 22 years older since I moved here, with health problems and a back and neck injury, and couldn't possibly deal with them all myself.
