Flower colors include red, peach, white, bicolor, and more. Flower shapes are divided into double and single petals.Ecological habitsNative to Brazil in South America. Prefers a warm, humid, and sunny environment. The optimal growth temperature is between 18°C and 20°C, with winter temperatures not lower than 5°C, and summer temperatures not exceeding 32°C, as stem and leaf growth may be poor. Requires more water during the growing period, is not drought-tolerant but also fears waterlogging. Adaptable to sunlight, with uniform and bright flowers under sufficient sunlight. Avoids direct sunlight in summer. Requires well-drained sandy soil, is not drought-resistant, and fears waterlogging and salinity.Propagation methodsCommonly propagated by seeding, cutting, and division.Seeding method: Four-season Begonia seeds are easy to collect and have strong germination power. Seeds should be sown immediately after collection, usually in August or September in shallow trays. Potting mix consists of 1 part humus, 1 part rice husk ash, 1 part garden soil, and a small amount of superphosphate. Use coarse mud at the bottom of the pot and fine sieved soil on top. Generally, no soil is covered after sowing, the potting mix is moistened, covered with glass, placed in a semi-shaded area, and seedlings can emerge in one week. Flowers usually bloom 130 to 150 days after sowing.Cutting method: Can be done throughout the year. Select sturdy young branches as cuttings, make smooth cuts, and plant them in a greenhouse sand bed, maintaining humidity, and they will root in 2 to 3 weeks. Soaking the base of the cuttings in a 0.005% indolebutyric acid solution for 2 seconds can promote root growth.Division method: When repotting in spring, the mother plant can also be cut for division propagation. Divide the tubers when they are about to sprout in early spring, each piece with one bud eye, apply wood ash to the cut surface, let the cut surface dry slightly before potting. Do not plant too deep, half of the tuber should be exposed above the soil surface, as planting too deep may cause rot. Plant one divided tuber per pot.Cultivation managementUse a mixture of humus, rice husk ash, and garden soil, mixed with an appropriate amount of manure, bone meal, or superphosphate. During the growing period, apply a light fertilizer solution once a week, and add 1 to 2 times of phosphorus-potassium fertilizer during the flower bud formation period. Adequate watering is required for the potting mix to keep the soil moist, avoid drought, and reduce watering in winter. When the plant grows tall, i.e., 10 cm high, it should be pinched to promote new branch growth and increase the number of flowers. After pinching, spray 0.05% to 0.1% paclobutrazol solution 2 to 3 times within 10 to 15 days to control plant height. Maintain a warm, humid, and shady environment during the growing period. Avoid direct sunlight. Leaves often lose their luster in dry air. Four-season Begonia has a developed root system and grows quickly, so it should be repotted every spring after flowering, adding fertile soil.Purification functionFour-season Begonia can absorb toxic and harmful gases such as hydrogen fluoride from the air, purifying the indoor air.The above sharing on how to plant 四季 crabapple seeds and the complete content on the cultivation and management of 四季 crabapple, have green plant enthusiasts understood?
