My next door neighbour is elderly and her mental health has rapidly declined in the last few years, she doesn't let anything grow in her garden except for grass. This is fine except she has for the last year been throwing salt on the other 2 neighbours gardens on their shrubs. She also leans over the fences to cut anything she can reach.
My problem is that I now want to plant some hedging along the border with her and although I will put up some fencing I now she will throw salt over. Any recommendations for some really hardy plants that can withstand salt?! We are also in a really windy coastal area.
