Inherited a patch of brambles when we bought Exile Villas in 2012. Now the wedding's out of the way I'm turning my mind to other matters. So; the brambles have to go. They're strangling everything else. Winter's a good time to get rid of them. The ground's hard and the plants are dormant. A struggle to get the roots out in places, because they like to come through from next door. Strong weedkiller is a last resort, but likely to be necessary in spring once they start growing again.
