They are gorgeous, if greedy!
If you are a man or have one to hand, you can try weeing on all the trees and generally all around the orchard. Sounds sort of funny, but foxes are well known to be detered by human male
urine. Apparently they mistake it for the scent mark of a rival (and more testosterone-y) male fox and clear off, thinking they are in someone else's patch - which in this case, they are! The first wee of the day is supposedly the most... ahem... 'powerful'.
Naturally you need to do this regularly over the long term in order to be and remain effective, but it does (apparently) work quite well and is free. I haven't tried it.
It does not work for female urine unfortunately.
If you cannot find a male human anywhere to hand, you can apparently also buy a urea-based product that mimics this effect.
