The cultivation methods of Bai Ri Hong (Purple Wisteria) mainly include the following aspects: 1. Soil selection
Bai Ri Hong does not have strict requirements for soil, but it is best to choose fertile and well drained soil, with deep and fertile sandy loam being the best. This soil is conducive to the growth of the roots of Bai Ri Hong and provides it with sufficient nutrients. 2、 Watering management
Bai Ri Hong is drought tolerant and afraid of waterlogging. During the growing season, the soil should be kept moist, but excessive watering should be avoided to prevent root rot. Before sprouting in spring and after falling leaves in autumn, you can water once with green water and once with frozen water. If it is not too dry during normal times, there is no need to water it. During the rainy season, drainage work should be done well. When the temperature is high and the evaporation rate is high in summer and autumn, water once a day in the morning and evening, and increase the watering frequency appropriately during drought and high temperature. Watering should be reduced in winter to prevent root freezing damage. 3、 Lighting requirements
Bai Ri Hong requires sufficient sunlight and is best placed in a sunny location. But during high temperatures in summer, it is necessary to provide appropriate shade to prevent the leaves from being damaged by sunlight. Adequate sunlight is also needed in winter to maintain its healthy growth. 4、 Fertilization management
During the growing season, Bai Ri Hong requires regular fertilization. It is recommended to use organic fertilizers such as fermented bean cakes, bone meal, human manure or sesame paste residue. Before the flowering period, the use of phosphorus and potassium fertilizers can be increased to promote flower bud differentiation and improve flowering quality. Fertilization should follow the principle of "thin fertilizer and frequent application" to avoid burning plants with concentrated fertilizer. Apply every 10 days from the beginning of spring to the beginning of autumn, and reapply every half month after the beginning of autumn. Reduce the amount of fertilizer after autumn, and do not apply fertilizer during the dormant period in winter. Do not fertilize during rainy days and hot summers at noon. 5、 Pruning management
The growth rate of Bai Ri Hong is relatively fast, so it needs to be pruned regularly. Pruning is mainly carried out during the growth period and after autumn leaf shedding, mainly removing dead branches, diseased branches, overly dense branches, overgrown branches, downward branches, slender branches, and endophytic branches to maintain the beauty of the tree shape and ensure ventilation and light transmission. At the same time, excessive branches, overlapping branches, intersecting branches, and radiating branches should be promptly removed to avoid nutrient consumption. During the pruning process, appropriate pruning should be carried out according to the plant's morphology and growth conditions to maintain a beautiful shape and good growth status. 6、 Disease and pest control
The common pests and diseases of Bai Ri Hong include aphids, scale insects, prickly moths, leaf rollers, inchworms, powdery mildew, etc. When discovering pests and diseases, timely prevention and control measures should be taken. A combination of biological and chemical control methods can be used, such as spraying pesticides, removing diseased leaves and pests, etc. At the same time, it is necessary to strengthen daily maintenance management and enhance the disease resistance of plants. Regularly inspect plants, promptly identify and address issues. 7、 Winter management
Bai Ri Hong needs special attention in the cold winter. In northern regions, the 100 day red shift should be moved indoors or in a greenhouse to keep warm. In the southern region, it is possible to overwinter in place, but cold prevention measures should be taken. Maintain a suitable temperature range, between 18 and 29 degrees Celsius during the day and between 10 and 16 degrees Celsius at night. This temperature range is beneficial for the growth and flowering of Bai Ri Hong. 8、 Breeding methods
Bai Ri Hong can be propagated through methods such as sowing, cutting, and division. Sowing and reproduction occur in spring, where seeds are sown into loose soil to maintain appropriate humidity and temperature; Cutting propagation is carried out during the growing season, selecting healthy branches for cutting; Split propagation is carried out in spring, where plants are split and replanted.
The cultivation method of Bai Ri Hong is not complicated. As long as attention is paid to soil selection, watering management, light requirements, fertilization management, pruning management, pest control, overwintering management, and breeding methods, healthy and beautiful Bai Ri Hong can be cultivated.
