Rubber Tree 'Ruby'
Ficus in general can have a bit of a bad reputation for being fussy, but once you have an understanding of the conditions they expect they can be reliable members of your plant family for many many years to come!
Ficus are lovers of consistency, things that make them dramatically shed their leaves or produce unsightly almost always have to do with changes in their environment. If your ficus is throwing a fit consider what might have changed. Is there a cold draft hitting it? Are the roots more wet or dry than usual? Did you move it?
The good news is that even though ficus can respond dramatically they are also quite good at making a comeback!
