I took some clippings from the Gardenias to Brown Bros & Byrd this morning
(I love that place). They were pretty sure most of the problems were winter
damage. The black on top of the leaves and the white spots underneath some
of the leaves they felt were cause by an aphid problem at the end of last
fall.

They recommended a good feeding with Holly-tone and to keep an eye on them
to see if the new growth shows similar problems. Other than that they should
be fine.
