How to spend the winter with trees full of gold and jade
As a popular leaf-viewing and fruit-viewing plant, Jinyu Mantang is deeply loved by family growers for its auspicious meaning of red fruits and green leaves. However, its winter maintenance often makes it difficult for novices. This article will systematically analyze the key skills of wintering from environmental regulation to daily management. Environmental regulation Two core sciences for indoor insulation When the temperature falls below 10℃, it is necessary to move the golden jade trees indoors in time. The maintenance position should be more than 2 meters away from the air conditioning outlet to avoid dehydration and scorching of the leaves. It is recommended to use a combination of double glazing windows + gauze curtains to maintain the ideal temperature of 15-20℃ and buffer the temperature difference between day and night. Precise lighting management requires more than 4 hours of direct light every day, and preference is given to southbound bay windows or closed balconies. In case of continuous rainy weather, LED plant lights (power 30W/㎡) can be filled at intervals of 2 meters, and the light can be filled for 3 hours a day to prevent fallen leaves. Pay attention to rotating the flowerpot 180° regularly to ensure uniform light reception. Three principles of water and fertilizer management The stepped water control plan adopts the strategy of "watering according to the weather" in winter: watering thoroughly once every 15 days at 5-10℃; once every 10 days at 10-15℃; and once every 7 days above 15℃. It is recommended to use the bamboo stick test method: Insert a 30-cm bamboo stick into the pot soil, and after pulling it out, only the tip is slightly moist to replenish water. It is forbidden to completely stop fertilization when the room temperature continues to be less than 15℃. When the temperature reaches the standard, potassium dihydrogen phosphate (concentration of 0.1%) can be applied once a month for foliar topdressing to enhance the cold resistance of the plant. Be careful to avoid moving the potted plant within 3 days after fertilization. Key measures for plant maintenance Golden pruning opportunity Carry out styling pruning from December to February of the following year: Remove invalid branches such as crossing branches and sick and weak branches, and keep the main branches at a 45° angle. Implement the "three-cutting method" for the flowering branches of the year: leave 3 buds for the thick branches, 2 buds for the middle branches, and 1 bud for the thin branches to ensure the quality of flower bud differentiation in the coming year. Pest and insect pest prevention check the hidden dangers of red spiders on the back of the leaf every week, and find a small amount that can be wiped with a 75% alcohol cotton sheet. Keep the environment ventilated and regularly spray azedra oil (1:200) to prevent scale insects. Spraying diatomite on the surface of the basin soil can effectively control the root mealybug.
Through precise temperature control, scientific water and fertilizer management and timely plant pruning, the golden jade full tree can not only survive the winter safely, but also lay a solid foundation for the prosperity of flowers and fruits in the coming year. It is recommended to make a maintenance log every month to record changes in temperature, humidity and plant status, and gradually master the personalized maintenance rhythm.
