Ancient Pear Tree in Tarmac
I wonder if anyone can offer me some advice please - I have a very old pear tree against the side of my cottage and the roots and trunk are surrounded right up to the cottage wall by Tarmac, as it forms part of the driveway. In the last year or so I've noticed that either the trunk is eroding or the Tarmac is breaking down around the base exposing a gap between the trunk and tarmac, meaning I can put my hand inside the trunk (it's hollow) at the ground level. I'm really concerned that something might get in, it may be open to disease etc. Should I fill it with earth or similar? Does it need new Tarmac to seal the area up again? This seems drastic to me, but I need to do what's best for this very old pear tree which is an integral part of the cottage's infrastructure. Any advice would be very much appreciated please. I've attached 2 photos, one of when it had plants around the base a few years ago and one of how it is now, showing the exposed area.
