How to care for Bai Xue Guang, cultivation techniques for Bai Xue Guang.

How to care for Xue Bai GuangMany succulent plant enthusiasts are fond of the silver-white绒毛 and spherical appearance of Xue Bai Guang, but many encounter problems such as plant leggy growth and root rot during maintenance. This article will systematically analyze the six key elements of planting Xue Bai Guang, using scientific maintenance methods to bring out the best condition of your Xue Bai Guang.I. Light ManagementA. Seasonal Light ControlXue Bai Guang is native to the arid regions of South Africa, requiring 6-8 hours of direct sunlight per day in spring and autumn, and can be extended to 8-10 hours in winter. In summer, 50% of the sunlight should be blocked with a shading net at noon to prevent strong light from burning the绒毛 tissue.B. Supplemental Lighting TipsIn northern regions, full-spectrum plant lights can be used for supplemental lighting in winter, maintaining a distance of 30cm, with 4 hours of supplemental lighting per day. Insufficient light can lead to leggy growth and elongated spheres, affecting the ornamental value.II. Water ControlA. Watering Cycle DeterminationUse the bamboo stake test method: insert a bamboo stake 2/3 into the potting soil, and if it comes out dry after 15 minutes, it's time to water. Water thoroughly every 15-20 days in spring and autumn, and give minimal water once a month during the summer dormancy period.B. Special Condition HandlingDuring continuous rainy days, watering should be postponed, and humidity can be increased by spraying the surrounding air. New plants should be allowed to rest for 7 days after repotting before watering to avoid root wound infection.III. Matrix FormulationA. Soil Golden RatioRecommended formula: 40% red jade soil + 20% deer swamp soil + 15% volcanic rock + 15% vermiculite + 10% rice husk charcoal. Particle diameter should be controlled between 3-5mm, ensuring that the drainage speed is completed within 5 seconds.B. Repotting PrecautionsRepot every 2 years in spring, retaining 1/3 of the protective soil. After repotting, place it in a well-ventilated and shaded area for 10 days, then normal maintenance can resume once new roots have emerged.IV. Nutrient SupplyA. Fertilizer Selection CriteriaUse organic liquid fertilizers with an EC value ≤1.0, diluted to half the concentration stated in the instructions. A cactus-specific fertilizer with an NPK ratio of 3:6:9 is recommended, supplemented with calcium and magnesium trace elements.B. Fertilizing TaboosAvoid using uncomposted farm manure, and do not apply nitrogen fertilizer to the foliage. Do not water within 3 days after fertilizing to prevent sudden changes in fertilizer concentration from damaging the roots.V. Environmental ControlA. Temperature and Humidity ManagementMaintaining a day-night temperature difference of 8-10°C is most beneficial for growth, with winter temperatures not below 5°C and summer not above 35°C. Air humidity should be controlled between 40-60%, with enhanced ventilation during the plum rain season.B. Pest and Disease ControlWater with a carbendazim solution (800 times) once a month, and immediately remove scale insects with a 75% alcohol cotton swab. During the peak period of red spider mites, hang yellow sticky traps to prevent them.By systematically mastering the four core elements of light, water, matrix, and nutrition, combined with environmental control, you can cultivate Xue Bai Guang with full, silver-white绒毛. It is recommended to establish a maintenance log, recording each watering and fertilizing time, and gradually exploring the maintenance rhythm most suitable for the local climate.
