I have a very full, thick rubber plant that I've had for 2 years. It was repotted last year but I didn't know it needed a pot with holes. There are at least 3-4 new healthy stems flourishing at the bottom. Do I have to repot if it is doing so well?
Drainage is key to success with any plant. The soil and container must drain away any excess moisture.
I would suggest repotting into a container that has a drainage hole.
