I have an enormous eyesore of a concrete block wall surrounging my yard. I've been thinking of ways to cover it up. The wall is damp and damaged in places so it would be difficult and expensive to plaster. I was thinking about growing climbing plants up along it and was wondering how effective this would be at hiding the wall. Are there any plants which would be best suited for this task? How long would it take before the results would show? Are there any, more effective alternatives which won't cost an arm and a leg?
Thanks in advance for the advice.
