Ginkgos are supposed to be disease resistant, but I am worried about ours. It is about 60 feet high and has always been fine. But now I can see bare branches near the top and bits of it are looking droopy. Should I be worried? It should have had enough water this year at least - I suspect that its roots are well into the sewers in the main road! Any ideas - or ideas where I could seek help? We are in West London
Thanks
