think your neighbour has poisoned it, plant another, and set
up a webcam/cctv and get him on film next time. Costly, but if you catch
him, well worth it! If he did poison the tree, is that criminal damage? I
suspect it is...
Alternatively liberally spray a systemic weedkiller over the fence near
where your plants are dying and tell the neighbour you thing there is some
terrible disease around there cos *your* plants started dying and obviously
whatever caused it, has sparted to spread to *his* garden too.
