Begonia rex, commonly known as the Rex Begonia, is a rhizomatous geophyte native to subtropical regions. It is renowned for its striking foliage, which comes in a variety of colors and patterns. The plant belongs to the Begoniaceae family and is often grown for its ornamental leaves rather than its flowers.
Rex Begonias thrive in bright, indirect light and prefer moderate temperatures. They require high humidity and should be kept in a well-ventilated area. Water the plant regularly to keep the soil evenly moist but avoid waterlogging.
土壤
Rex Begonias prefer a well-draining, loamy soil mix. The soil should retain some moisture but not become waterlogged. Adding perlite or sand can improve drainage.
肥料
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant every 4-6 weeks during the growing season. Avoid over-fertilizing as it can damage the plant.
换盆
Repot Rex Begonias every 1-2 years or when the plant outgrows its current pot. Choose a pot that is slightly larger than the current one and ensure it has good drainage. Repot in the spring for best results.
传播
Rex Begonias can be propagated through leaf cuttings or division. The best time to propagate is during the growing season. Ensure the cuttings or divisions are kept in a humid environment until they establish roots.
修剪
Prune Rex Begonias to remove dead or damaged leaves and to maintain the plant's shape. Pruning can be done throughout the year as needed.
毒性
Rex Begonias are toxic to pets and humans if ingested. The plant contains calcium oxalate crystals, which can cause irritation and swelling in the mouth and throat.
