hi i think the previous tenant put a small 'ingrid melquist' rhody in the back garden. it's only about 18 inches high now. the soil here is towards alkaline which i believe is wrong for it, plus it has a position that would get quite a lot of bright sun in mid summer. i think he planted it as an experiment. i've recently noticed that some of the leaves are going brown and getting holes. it only seems to be on one side of the plant at the moment. i've linked some pics from photobucket:

any ideas what it could be? i think it had some browning of leaf tips before snow recently but seems worse now.

i'm a garden dunce i'm afraid, but would like to keep the rhody if possible. would it benefit from moving to a more sheltered, shady position? and would it be ok with being moved?
could it be grown in a large pot?

appreciate any help. thanks
