London, United Kingdom

Our Ceanothus Tree which is about 8-10 feet high and probably 15 years old flowered in the spring and we noticed about 3 weeks ago all the leaves & brances went BROWN. Do you have any idea what has caused this and whether the tree has now died. We would love to keep it as it is a very special tree to us. Thank you, Pauline Lewis of North London
