Begonia rex is toxic for cats, dogs, and humans if ingested.
Overwatering is often caused by soil that is too dense. An overrated Begonia will get yellow leaves.
Underwatering leads to brown leave as well as dry leaf tips.
Dense soil and overwatering often lead to root rot. Remove soft roots and rinse the healthy roots. Exchange the potting soil and disinfect the pot.
