Badly Burn't Salix

Nor do I, but compensation or recognition would be good.

It was mean't to be a little Salix to go in a pot bought from Asda but it just kept on growing.

 

The damage looks fairly superficial, relative to the size of the bush so I am sure it will recover, eventually. There is plenty of foliage on it, on your garden side.
I wouldn't waste time or energy being upset with your non gardening neighbours, they will just laugh it off because in their minds they have repaired the damage, they probably think the whole incident one big laugh. The more you show how upset you feel, the funnier they will think it is.

 

Today I have bought a photinia and put it in a pot to try and screen the salix while I wait for a year to see if it will recover.
