My neighbours fence was only waist height so I put up 6ft trellis on my side for privacy, through this grew dense planting to screen out their garden. This morning they're having their fence replaced and they've torn down & thrown away my trellis too! All the greenery has also gone.
Separately, the previous owners (their side) planted a tree against their fence. The tree grew so much that it's roots have lifted the concrete base their shed stands on (immediately adjacent) and it's moved over into my garden a bit. Also the tree trunk is now so large that they can't put a new fence up behind it (on my land) so they're going to fence up to it either side. But this means I now have part of their tree encroaching on my garden & I'm not happy about it. Am I being unreasonable? They never consulted me about this & I'm a bit pissed.
