Why are my Rex Begonia leaves turning yellow?
Yellow leaves on a Rex Begonia are usually a watering problem, most often too much water. Make sure the pot has drainage holes, empty the saucer after watering, and let the top soil dry between waterings. Old lower leaves also yellow naturally as the plant grows.
