My varigated ivy is turning brown and dying. It is about 15 years old and growing on a big tree.i have not fertilized it so far, and the plant was doing great. The tree it is attached to , is doing well, however, the ivy is dying. (It all happened in the last two weeks or so.) It is in Dallas, tx. Plant has grown as high as 40/50 feet.
please help...any way to save this plant ?
