Begonia X tuberhybrida or Non-Stop Pink are magnificent, large flowered hybrids that grow from a tuber. They have a compact, bushy habit that will reach 12-18 inches (30-45 cm) tall.
Blooming Time: Summer through the fall the 2½ to 3 inch (6.5-7.5 cm) blooms cover the plant. Very showy!
Culture: Begonia X tuberhybrida need a moist, fast draining soil mix with filtered shade or high interior lighting. In the greenhouse, we use a soil mix consisting of 2 parts peat moss to 1 part loam to 1 part sand or perlite. Tubers that have been stored for the winter are planted in shallow flats in February. When the tubers have sprouted and the plants are 3 inches (7.5 cm) tall, they are transplanted to 6-10 inch (15-25 cm) containers. Keep the soil moist but not soggy. If leaves turn yellow then you are over watering. Fertilize weekly with a high nitrogen fertilizer diluted to one-quarter strength until mid-May. At this time, we alternate 20-20-20 fertilizer and 15-30-15 fertilizer diluted to ½ the strength recommended on the label on a weekly basis throughout the growing season. In the fall, when leaves begin to turn yellow and wilt, you should reduce watering until the stems fall off of the tubers. Lift the tubers out of the soil and let them dry for 2-3 days before storing. Store in a cool dry environment until spring.
Propagation: Begonia X tuberhybrida are propagated by cutting, seeds and tubers. Tubers are sold in garden centers starting in February and cuttings can be made at any time during the growing season.
Begonia X tuberhybrida was featured as Plant of the Week January 9-15, 2004.
