Vole guards protect young trees from damage by voles and mice. Vole guards are a tightly rolled plastic cylinder and designed to hold its shape and retain sufficient overlap to enable the tree guards to expand as the tree grows. Vole guards can be pulled open to fit around the young tree and will then spring back into shape , enabling them to be simply pushed into the soil to create an effective barrier against vole and mice attack. Supporting bamboo canes are not necessary if the guards are installed correctly into the ground, but they can be used as and additional support if required. Vole guard is manufactured from polypropylene which does not harm the environment.
