Hi Andy, pictures would help us a lot to help you with this problem. A full shot of the plant, then close-ups of the problem areas as well, please?

Also if you could give us your location, that might also help since a lot of tree problems can be weather/climate related. Just fill in your profile with your city/state/country and it will appear in the upper right of all your posts.
