How do I bring my 16 year old arrowhead plant back to health? I received my arrowhead vine 16 years ago when my son was born. We recently moved into a new home with low light. No matter where I move it, I can't get it to bounce back. It always seems dry, yet when I water it (I don't over water), it doesn't help either. I don't want to lose this plant... What do I do?
