Hi Jo,in response to your question 1, as far as i am aware that there is the "RIGHT TO LIGHT" law regarding other peoples properties that may affect you,i.e.trees. However i have trees in my back garden and several of them,may i add and this lady is talking codswollop. If there are signs that this tree is causing damage,then you may have no choice but to take it down,otherwise in the long run it may cause serious damage and cost you lots of money. Otherwise,contact your local council and find out the height laws and keep it constantly maintained. Do not let this woman dictate to you what you must and musnt do,its your property and your job to maintain it,stick to the law and then let her moan all she likes. Nature was here b4 she was!!!
