I have a rubber plant I bought at Sam's 2 years ago. It has three
plants in that pot. I didn't move it to another pot. I fertilized it
twice a year. Of late I'm seeing that the new leaves are getting
smaller and smaller. The big leaves all fell off. So the plants don't
have any leaves in the bottom half. They are just bare. So I airlayerd
them and want to move to a bigger pot in hopes of making them look
better. My question is after they develop roots and I re-pot them,
will they grow bigger leaves?

Thanks.
