Philodendron - black on stems and leaves
Hello, I have a philodendron vine I picked up from a garden shop and put outdoors in mostly shade. The pot wasn't draining well and I'm sure it was too wet. I re-potted it to let it dry out some but it has black on many of the stems and doesn't produce new leaves in those areas. Many of the leaves fell off and some show signs of looking pale and some brown spots here and there. The main concern is these black portions on the stems. Is there a fungicide or anything that can be applied to save it? Could it be cut back and maybe it will re-grow? Thank you.
