I have recently purchased a couple of begonias a few weeks ago. Was told not to repot them as this is the blooming season. I knew this when I bought it. Sorry babbling. I was wondering is there any way to fix a begonia that has split at the base and one branch has died and the other is hanging on by a thread. Can I repot the the root stock and start over or do I have to just cut my losses and buy a new one?
