Hi there. I have lived in my house for more than a decade. It is an 'elevated semi' which means that I have a massive bed at eye level height from the pavement, at the front of my house. It was taken over by Montbretia when I bought the house and it still is. It is a massive flower bed basically, at least 40 feet x 18 feet. What can I do with it? It is a SORT OF rockery, but I live close to a park. I have thuggish trees in that bed too! Any ideas?
