hi all. I have posted before about the issues I have inherited with the paving in my rental garden Softening 'concrete' flagstones in a victorian coutryard garden and thankfully received some great advice. The garden is looking fab this year thanks to recommendations from GC members, but I've now run up against another issue. I have a very large tree at the end of the garden (I haven't measured it, but it's as tall as my three storey house and the trunk is around two feet in diameter - you can see it in the far right hand side of the picture) and the roots are now making the paving so uneven that some slabs stick up over 3" higher than those next to them. It's a real minefield and only a matter of time before someone falls over (again!). I've spoken with a friend who runs a gardening round and he suggested lifting the slabs at that end of the garden and laying a thick bed of slate chips instead, therefore countering any unevenness. This seems a good idea to me, but I have a (very much loved) cat and I'm told they don't like them. Pea shingle is out as apparently they use that as a toilet, so I wondered if anyone else had any ideas? The landlord is cool with whatever I do, so no probs about lifting and removing the slabs. Any recommendations greatly appreciated, Stu.
