I have an English oak tree in my garden which is loosing its leaves later each year. 20 years ago, the leaves would be off the tree by late October. As the years have passed, the leaves stay on longer and in Dec 09 were still on well into the month. In Dec '10 , the leaves were still on the tree and mostly green despite the severe weather and are still on the tree now , Jan 8th 2011. Any ideas?
