how do you keep foxs out of your vegetable plots

Human hair hung around the site at regular intervals.
Or human urine, preferably male! But neighbours may complain if you start ... around plot!

You can by lion poo pellets form garden centre, they are meant to scare cats, but may work for foxes.

Not sure of anything else

Sometimes it is better to have a fox than Rabbits. I once had a piece of ground left unwired because there was a Foxes den in the hedgerow, Nothing ever got nibbled , but when the babies arrived they sat on my seed bed of young trees and turned them into Bonsai.

Foxes digging holes... take their spades off them ;-)

ha ha good one?
i will lock the shed so he can't plant the seed as well?

My dog chases people on bicycles... so I took his bicycle off him, ba bum ;-)
