Cheers Moonraker - as for the tree, well it seems to have already died this year. It was doing well after being pollarded the year before, but suddenly lost all its leaves and never recovered. The ground dried out very badly this summer, and we had also kept some chickens under the tree for a while - I'm not sure if the chicken poop had anything to do with it, but certainly the lack of water seems to have done for it... Shame, as it was a lovely tree. You can get your whole hand in some of the cracks in the bark now.
Andy had planned to cut it down and stack the wood in the shed for next winter...
