How to grow miniature rex begonias: The care of mini rex begonias is the same as that of standard-size rex begonias. They can take sun or shade, though they need to be protected from harsh direct sun at midday. The level of light they receive can make their leaf colorings and markings more or less vivid. Repot with fresh soil once a year, using row a light-textured potting mix and allow it to dry slightly between waterings. Mini begonias may need watering every day, because small pots can dry out quickly, especially if they are made of clay, which seems the best choice for rex begonias as it lets air circulate to their fine roots. Feed regularly with an all-purpose houseplant fertilizer, following the directions on the package.
