Begonia is a huge diverse genus with over a thousand
different species. The genus is represented by various groups including: Semperflorens, Rex-cultorum, Rhizomatous, Tuberous (Multiflora and Pendula), Cane-stemmed, Winter-flowering, and Shrub-like.
Caring for your begonia is simple. Keep the soil moist not wet, bright light not direct sun, pinch the flowers and as far as fertilizing begonias is concerned, the general rule is to go lightly.
In terms of caring for the plant when winter arrives, it boils down to whether one has a fibrous root, a tuber, or a rhizome. If you live in a cold area, you may want to grow semperflorens (wax begonias) in pots so you can bring them in when it gets cold.
Begonia tubers cannot remain in the soil over the winter in very cold climates. Wait until after a killing frost, and then dig up the tubers. Shake off any excess soil and let them dry in a warm spot for several days. Cut off any bad spots and then carefully pull the roots, stems and leaves off the tuber. Wrap each tuber in a brown paper bag or wrapper and put them in a cool, dry place for the winter.
