Gardenia with brown edged leaves
My gardenia was looking absolutely gorgeous this entire winter and then recently it began to develop yellow leaves. I added some iron, but they kept getting yellow and falling off. I have been fertilizing with Miracid on a regular basis, have added epsom salts and added more iron. Finally, the weather warmed up so I put it outside. The yellowing has stopped, but now the leaves are getting brown along the edges, just a few at first, and now at least half. I am letting it get dry before watering, because I thought maybe it was too wet. Now I just don't know what to do. It looks horrible. Any ideas?
