The reason why Yushu only grows leaves and does not bloom
As the "iron tree" in the succulent plant world, Yushu flowering has always been a topic that horticultural enthusiasts talk about. Many yushu trees that have been maintained by flower friends for many years have always seen only green leaves and no buds. What maintenance misunderstandings are hidden behind this phenomenon? This article will deeply analyze the key factors affecting the flowering of Yushu and provide scientific and effective solutions. Analysis of the core factors of Yushu's failure to blossom. Imbalanced fertilization ratio Excessive nitrogen is the primary culprit hindering flower bud differentiation. Excessive application of high nitrogen fertilizer during the growing period will stimulate the growth of branches and leaves. It is recommended to alternately use ternary compound fertilizers (nitrogen, phosphorus and potassium 20-20-20) and bone meal every month, and add potassium dihydrogen phosphate (diluted 1000 times) for foliar topdressing during the bud stage. Yushu with insufficient plant maturity needs to reach a physiological maturity period of 5-7 years before it has the ability to blossom, and the probability of flowering for young plants is extremely low. It can be judged by observing the lignification degree of the main stem that when the diameter of the main stem exceeds 3 cm and presents a gray-brown bark texture, the plant enters the reproductive growth stage. Improper water management Implement the "dry and wet cycle" maintenance method in spring and autumn: delay watering for 3 days after the basin soil is completely dry, maintain micro-tide in the substrate during the high temperature period in summer, and strictly control water in winter (≤2 times a month). Especially during the flower bud differentiation period (September to November), appropriate drought stress can effectively stimulate flower bud formation. Advanced maintenance technical points: Light cycle control 6 hours of direct light per day combined with 8 hours of scattered light is an ideal lighting solution. The light can be extended to 14 hours per day by artificial filling light, and a full-spectrum plant lamp can be used to illuminate 30cm away from the leaf surface. The flower formation rate can be significantly improved for 45 days. Temperature difference stimulation techniques Maintain a temperature difference between day and night of 10-15℃ in autumn, and control the temperature at night between 12-15℃. This environment can activate flowering genes if it lasts for more than 20 days. Closed balconies can be used to create temperature differences in the north, and windows can be used to ventilate at night in the south.
By systematically adjusting maintenance strategies, 80% of healthy adult plants can blossom within 3 growth cycles. It is recommended to establish a maintenance log to record data such as temperature, humidity, fertilization cycle, etc., and gradually find out the most suitable flowering plan for the plant. Remember that patience and scientific management are the key to unlocking the Yushu Blossom password.
