Foxes are lovely creatures but can cause an awful lot of damage in the garden. They are becoming increasingly at home in urban gardens and will even make their den under a garden shed. They dig up or trample plants, either when they are foraging for food or just playing.
It is very difficult to stop foxes coming into the garden as they are agile animals and can climb fences and walls as easy as a cat, along with the additional ability of digging under obstacles. Also avoid using blood or bonemeal fertilisers as they think there is food under the plant so will dig it up
