I have 4 limelight hydrangeas. I want to remove the 2 ficus? (I think that's what they are called) and replace them with the 4 little limes I also want to remove the spirea and add a tree or an evergreen but nothing that gets very big that corner faces the west so I want the sunset light to get to our windows. I was also thinking of removing the evergreen hedge. Should I add more little lime hydrangeas? Maybe some boxwoods?
