Some background for my comment on a post about garden theft at GardenRant.
Here's a shot from my roof. That's my yard on the left and his on the right. Note that I am taking this picture from three stories up.
This is wisteria that threatens my house. It is quite literally destroying his house. Again, we're three stories up.
Those are his house vents it's growing on.
Here it is coming for me. I just pruned it two weeks ago, and already this. Imagine what would happen if I slacked off.
This is the view from my second story living room window, and a slight rightward pan. You can't really see how his plants are bowing the fence, but trust me, they are. You see those rocks at the bottom of the fence? They're there to block tunnels dug by the mouse/rat that keeps coming over.
(That bamboo (three stories tall) is actually growing in the big water-filled planters I put mosquito dunks in.)
These are my neighbor's back stairs.
Underneath is where I think the mice and raccoons live. The mice might actually be rats, I can't tell.
And I forgot to mention this: a windy storm last year helped the wisteria rip the vine-choked trellis from his house. It's about to fall into my yard and crush a 2 year old Dicksonia. (Sorry the shot is blurry; but trust me, the trellis leans menacingly.)
This is my southern exposure, after two hours of me pruning his "shrubs" back to the property line.
ADDED: At least I don't have to worry about...pigs!
Also: by next spring, I won't even be able to trespass into my neighbor's yard. It will be too overgrown to admit human-sized creatures.
