How to Prune a Rex?
I have a very pretty and otherwise healthy rex begonia. It started out as a tiny, half-dead Walmart offering in a 2.5" pot and now is in an 8" pot. It does well under fluorescent plant lights and our low California humidity.
Lately the leaves on the ends are getting smaller and more silver and the stems are getting long and bare inside. It is probably time to prune it somehow but I'm not to sure how to do so without really making the plant look bad for some time, since it is one of the stars of my living-room plants.
Any suggestions? (It doesn't like getting moved around so it is sulking in this image.)
