What to do if the leaves of white wax turn yellow
As a high-quality bonsai material, the problem of yellowing leaves of white wax plagues many plant lovers. This article systematically analyzes the causes of yellow leaves and provides professional treatment plans from the three dimensions of metabolism rules, environmental regulation, and nutrient supply to help you quickly restore plant health. Scientific maintenance, management and natural metabolic treatment techniques apply to white wax that goes through 2-3 natural leaf changing periods every year. At this time, it is normal for the old leaves at the bottom to turn yellow. It is recommended to use disinfectant scissors to cut obliquely at 45° along the base of the petiole to avoid damaging the new bud points. After pruning, spray 800 times carbendazim solution to prevent infection. Golden rule of water control Potting white wax must follow the principle of "seeing dry, seeing wet": judgment on water shortage: water shortage: pour through stagnant water treatment when 2 cm under the surface soil is dry: tilt the flowerpot to pour out the stagnant water, loosen the loose soil and raise the bottom of the basin. Watering period: Spring and autumn 9-10 a.m., summer 18-19 o'clock nutrient supply regulation fertilizer application standard growth period (March to October) Apply nitrogen-phosphorus-potassium compound fertilizer diluted 1000 times every month, and stop fertilizer during the dormant period. When fertilizer damage is discovered, immediately soak the basin with clear water for 3 times continuously, each time lasting 20 minutes. Environmental factors Optimize light intensity management Maintain direct light for 6 hours in spring and autumn, and use 50% sunshade net for protection in summer. In winter, indoor maintenance requires 1.5 meters away from the window, and rotating the flowerpot 180° every half of the month to ensure uniform light reception. Temperature gradient control establishes a three-level protection mechanism: move into an indoor basin below 5 ° C and wrap it with insulation cotton and spray antifreeze on the leaves. Through systematic investigation of the causes of yellow leaves and implementation of corresponding measures, more than 90% of the problems with yellow leaves of white wax can be improved within 2-3 weeks. It is recommended to establish a maintenance log to record key data such as water and fertilizer management and environmental parameters to form a personalized maintenance plan.
