How to cultivate West Sui Begonia
Let me tell you about the cultivation of West Sui Begonia and the maintenance points of green plants and flowers for everyone, let's take a look together!
West Sui Begonia is a small deciduous tree of the Rosaceae family, also known as海棠, Zimu Begonia, Xiaoguo Begonia, or Hongfeng. It is a common cultivated fruit tree and ornamental tree. The tree posture is upright, and the flowers are dense. The fruit has a sweet and sour taste. West Sui Begonia stands tall among Begonia flowers, resembling a graceful girl. With red flowers, green leaves, and beautiful fruit, it is very beautiful whether planted alone, in rows, or in clusters. The flowers are bright and colorful, usually planted in gardens for greening. West Sui Begonia has an upright posture among Begonia flowers, resembling a graceful girl. The flowers are pink and red, the leaves are tender and green, the fruit is delicious, and it is very beautiful whether planted alone, in rows, or in clusters. West Sui Begonia can be planted in the courtyard or dwarfed as a potted landscape, suitable for viewing flowers and fruit.
West Sui Begonia is native to the northern provinces of China, prefers sunlight, is cold-resistant, avoids waterlogging, and is drought-resistant. It blooms in April, with a flowering period of more than 10 days. The roots tend to produce suckers.
I. Propagation methods of West Sui Begonia: Begonia is usually propagated by grafting or dividing, and can also be propagated by播种, layering, and root cutting. Seedlings obtained by grafting can bloom earlier and maintain their original excellent characteristics.
1. Grafting propagation method: Use seedlings from seed propagation as the rootstock for branch or bud grafting. Spring grafting is done when the sap flows and the buds germinate, and autumn grafting (July to September) can be done with buds. Branch grafting can be done using methods such as cut grafting or split grafting. The scion should be selected from the middle part of a one-year-old branch that is fully developed (with more than two plump buds). After grafting, cover the scion with fine soil. Bud grafting often uses the "T" method, and if the bud is fresh and the petiole falls off after about 10 days, it indicates that the grafting was successful. A few days later, the binding material can be removed. When the seedlings are 80 to 100 centimeters tall, train the main branches, and then only prune dense branches, inward branches, overlapping branches, to maintain a rounded tree crown.
2. Division propagation method: The roots of West Sui Begonia tend to produce suckers. Division is done in early spring before germination or in autumn after defoliation. The method is to dig up the suckers from the rootstock, cut them into several single plants, or group 2-3 suckers with roots together for transplantation. After transplanting, water thoroughly, pay attention to soil moisture conservation, and provide shade if necessary, watering in dry periods.
3. Seed propagation method: Seed propagation is mainly to provide rootstock for grafting. The growth of seedlings is relatively slow and prone to variation, so seedlings are not usually cultivated directly. The common播种 methods are drill sowing, broadcast sowing in furrows, or broadcast sowing on the ridge. After sowing, cover the soil so that the seeds are not visible, and use straw or plastic film to keep the soil moist. The suitable temperature for seed germination is 18-24°C, and seedlings can emerge after 15 days. After germination, remove the covering material promptly and thin out weak, leggy, and杂 seedlings. Maintain good air circulation and sufficient sunlight, and strengthen fertilizer and water management during the seedling stage. The seedlings can be transplanted in late autumn of the same year. It takes 5-6 years for the seedlings to bloom.
II. Courtyard planting and management
Begonia is usually planted in the ground, with the best planting time being early spring before germination or early winter after defoliation. Keeping the complete root system of the seedlings when digging is key to their survival. Large seedlings should be wrapped in soil, and small seedlings should be left with some soil. After planting, strengthen management to keep the soil loose and fertile. Prune once from defoliation to early spring before germination, cutting off weak and diseased branches to keep the tree crown open and well-ventilated. To promote abundant flowering, cut back on the vigorous branches to reduce nutrient consumption for发芽. Resulting branches and蹭 branches do not need to be pruned. During the growing period, if you can pinch the tips early to limit nutritional growth, the effect is more significant. After planting, keep the soil loose and fertile, prune once in spring, cut off dead and weak branches, keep the tree shape open, and pay attention to the prevention and control of diseases and pests.
III. Potted plants
Usually potted before Qingming Festival. Place broken tiles at the bottom of the pot, then add some decomposed cake fertilizer, crushed bones, fish bones, chicken feathers, etc., as base fertilizer, then fill in the culture soil. When planting, trim the long lateral roots, injured roots, and excess fibrous roots of the海棠 plant. Make sure the roots are spread out, fill the soil to half the depth of the pot, then lift and shake the plant slightly to compact the soil. Do not plant too deep, keeping the rootstock level with the pot opening. If it is too shallow, it affects survival; if too deep, it affects the growth of海棠 after transplantation. After planting, water thoroughly.
Cultivate in a shaded environment for about a week first, then move to a sunny place after the roots recover. Initially, add more soil to the roots, and gradually raise the roots, adding拳石 to create a landscape with a mountainous wild charm. To make海棠 flowers and fruit abundant, water and fertilizer management should be strengthened. Apply 1-2 times of mixed phosphorus and nitrogen fertilizer before flowering, and every half month apply a thin phosphorus-potassium fertilizer. You can also use the method of heating to promote flowering in the middle of winter, moving the potted海棠 landscape to a sunny place in the greenhouse, watering, applying liquid fertilizer, and spraying water on the plant stems and branches every day, keeping the room temperature at 20-25°C. After 30-40 days, it can bloom for the New Year or Spring Festival decoration. After planting, cut back the long branches and pinch the tops, keep the soil loose and fertile, remove standing water from the pot after rain. Prune once in spring, cut off dead and weak branches, keep the tree shape open, and you can shape the branches of the begonia into curves, round, or spherical shapes. Maintain good ventilation and light, and pay attention to the prevention and control of diseases and pests.
