There is a plum/ damson tree in a private garden near my house. It is just the other side of their fence. However, the tree overhangs a public footpath with lots of juicy looking fruit which are crying out to be picked. Can i pick the fruit which overhang or can they report me for scrumping?
I used to love scrumping in my youth, don't think about it then, but in reality, its stealing, i'd do as suggested and ask, i'm sure they'd say yes, otherwise the overhanging fruit will go to waste, another point, once dropped, they could could pose a danger to passerbys, bit like stepping on a banana skin.
A piece of friendly advice. If you do ask the owner be careful about the terminology you use i.e. do not say "I'd love to get my hands on your plums!!" especially if the owner is male and bigger than you.
