Hi Everyone...I am new to this forum and could use some help.I have 2 Schefflera plants that are from my parents funerals. One is 21 years old and the other is 6 years old. The old one I almost lost years ago but I put a leaf stem in dirt and it survived. Since that point it has been huge. One large stalk and the leaves could get a foot or more wide. Just recently all the leaves have fallen off and I only have a stalk. What can I do to help save it? My 6 year old is a single stalk and thriving but it is almost to my ceiling. How do I prune it and will both the top and bottom survive? I love plants but really don't know much about them.These two mean a lot to me. Can anyone help?PLEASE
