How to Care for the Plant

Water
Begonia Rex are very picky drinkers! While they are susceptible to root rot, they prefer constant moisture with only slight drying between waterings. Therefore, water thoroughly and allow any excess to drain away from the roots. Remember to place a plate beneath your pot to catch the excess water.
Pruning
Snip away withered leaves with a clean pair of scissors or knife.
Fertilizer
Apply a balanced (preferably liquid) fertilizer with a 10-10-10 formula every other week.
