hi, my friend has a neighbour who has a large sycamore treeing growing
within a couple of feet of his house and he has worries about it damaging
his foundations. also the neighbour has piled rubbish against his fence
which is damaging it. (scaffolding poles distorting the wooden panes).

he has written to the neighbour (who lets the house and is never there) with
no response. could he; 1. poison the tree and 2. push all the rubbish away?
or what should he do? thanking you for any advice. john west
