Ravaged by possums

At this time last year this arch was covered in flowers from two varieties of roses.  At the moment there is only a single rose to be seen as the possums or possum have been eating the shoots.  I don't know what I can do about this.  Perhaps I will cover the arch with a netting that would make it more difficult for the vermin to nibble on the shoots.

With the shoots eaten away there is not a hope for the rose plants to develop buds and flowers.

This single rose survived the vermin.  I hope the buds alongside will survive to give some beauty in this ravaged spot of the garden.
