Hi there. I have a very mature silver birch tree in my garden which has just started to leaf, however some of the leaves have come out brown while others are green.
In the winter I removed my patio to make space for a vegetable patch and in doing so I uncovered a few of the top straggly roots. I have also got chickens living under the tree now. Could either of these be causing the problem and if so can I do anything to help the tree?
