    Fir tree is situated on the edge of our property on the right hand side as you look from the property.It has always been here. Problem is it has grown so much over the years, it seems quite top heavy and branches overhang the road. The tree is nearly as high as the telephone cables which serve the neighbouring property. It is situated just at the edge of our property by the fence adjoining our neighbours. You can see the roots coming through which is disturbing our driveway and neighbouring driveway. The roots are probably growing under the road too. We have bushes/shrubs right down to the tree.
