I help maintain the garden of a local Scout hut. Last Summer we had new turf laid down at the hut which has taken really well - too well as it now needs mowing! The area is surrounded by common land with 6 feet high nettles and brambles that keep on coming through the wire fence. We will never get rid of the nettles the other side of the fence but is there a way I can stop them encroaching into our land. The brambles I can almost manage by cutting them back but the nettles are beginning to pop up in the lawn around the edges. I'd rather not have to use weed killer. Could we grow some sort of creeper along the fence that may eventually block out the nettles? As our time is limited is there anything that would be low maintenance.
