My next door neighbour has planted a tree (ash) right next to our party fence and about 12 feet from the house wall.
I have asked him to remove it before it gets any larger it's small about four feet at the moment but he refuses to remove so how can I kill it as I haven't access to his garden? It's within easy reach right against the party fence.
Would a strong weed killer sprayed on the leaves do it?
Any advice gratefull accepted.
