How to Care for a Rex Begonia


If you’re looking for a houseplant that will add color to the indoor environment even on dark, winter days, Rex begonia is just the ticket. Although the pink blooms are lovely, it’s the big, bright foliage that makes Rex begonia a showstopper. Rex begonias can be a bit fussy, but the beauty of the leaves, in variegated shades of red, green, pink, purple or white, are well worth the extra effort.



things you’ll need:
  • Tray
  • Pebbles
  • African violet potting mixture
  • Container with drainage hole
  • Liquid houseplant fertilizer
    1. Provide a humid environment for the Rex begonia. To increase the humidity around the Rex begonia, fill a tray with pebbles and set the planting container on top of the pebbles. Add water to the tray of pebbles, but don’t allow it to touch the bottom of the planting container.
    2. Place the Rex begonia in an area with plenty of air circulation. Use a good-quality African violet potting mixture, and a container with good drainage holes in the bottom. Keep the plant clean. Pinch off any dead or yellowing leaves, and don’t let debris gather on the surface of the container.
    3. Water the Rex begonia whenever the top of the soil feels slightly dry to the touch. Water until the soil is moist, but don’t water excessively, as Rex begonia is susceptible to rot if the soil is too wet. Water on the leaves will cause spots, so don’t mist Rex begonia, and don’t allow water to splash on the leaves.
    4. Maintain the room temperature at around 70 degrees Fahrenheit. Rex begonias don’t do well in cool temperatures, so don’t allow nighttime temperatures to fall below 60 degrees Fahrenheit.
    5. Feed the Rex begonia every other week, using a balanced liquid houseplant fertilizer that has been diluted to half strength. Withhold fertilizer during the winter.
