Rieger Begonia is a unique winter-blooming variety, developed from a cross between Soco Begonia and various bulbous Begonias. Known for its compact growth, large and vibrant flowers, abundant blooms, and strong resistance to diseases, it’s an ideal choice for indoor cultivation. This plant can flower multiple times throughout the year, making it a favorite among gardeners looking for continuous color.
Lige Haitang thrives in warm, humid, semi-shady conditions and is not tolerant of extreme cold or high temperatures. It prefers high humidity and grows best in slightly acidic, loose, and well-draining soil rich in organic matter. Proper care ensures healthy growth and beautiful blooms.
During the hot summer months, when growth slows down or stops, it's important to prune the remaining leaves by 50% to 70%, and reduce watering to keep the soil just moist. Overwatering can lead to root rot, which may cause the entire plant to die. Once the weather cools in autumn, new shoots will begin to emerge from the base. When these reach a suitable height, cut back the old stems at the base with a clean knife and increase watering to encourage vigorous growth. Once the new branches are established, keep only three per pot, removing the rest to concentrate nutrients and promote faster shaping of the plant.
After October, as growth accelerates, maintain consistently moist soil and apply a diluted liquid fertilizer (0.2%) every two weeks to support healthy development. This helps the plant prepare for blooming during the cooler months.
In winter, ensure the plant receives sufficient light and maintain temperatures above 10°C. During the seedling stage, once the plant has four leaves, pinch out the growing tip to encourage lateral branching, resulting in a fuller appearance. Remove any excess flower buds promptly to prevent nutrient depletion and ensure better bloom quality. Also, regularly remove yellow or diseased leaves to maintain plant health.
Rieger Begonia is a short-day plant, meaning its flowering cycle is influenced by day length. When daylight exceeds 14 hours, it focuses on vegetative growth, while less than 10 hours triggers reproductive growth, promoting flower bud formation. This characteristic allows growers to control the timing of flowering, making it easier to plan for seasonal displays.
