I had something similar a few years back....after my missus got a dog and we unfortunately had to give her away it doesn't look anything like it did....which I'm a bit gutted about and pretty much means i have to get it re-turfed, new plants, fountain etc (yes she even managed to destroy that)
The tree has grown quite a bit but I have to keep on top with some loppers and the Japanese ferns have also c'mon really well (although one died)
Also doesn't help that the neighbour’s had that big white eyesore attached to the side of the house, then decided they wanted an extension in which their lovely builders just made matters worse.
I had to drill a hole through that Indian stone ball.....feck me...
