Causes of yellow leaves of jade butterflies and countermeasures
As a classic variety among succulent plants, jade butterfly is deeply loved by flower friends for its jade-like layered rosette shape. However, many novices encounter yellowing of leaves during the maintenance process, which not only affects the ornamental value, but also serves as a distress signal from the plants. This article will systematically analyze the three major causes of yellow leaves of jade butterflies and provide operable solutions. The three core causes of yellow leaves of jade butterflies, temperature fluctuations trigger stress reactions. Jade butterflies are native to the Mexican desert, and their optimal growth temperature zone is 18-25℃. When the high temperature of 30℃ continues in summer, leaf transpiration is intensified, resulting in dehydrated yellow leaves; when it is below 10℃ in winter, cell fluid freezes to produce frostbite patches. It is particularly important to note that when the indoor and outdoor temperature difference exceeds 15 ° C during the heating period in northern China, frequent moving of plants will cause metabolic disorders. Imbalance between light intensity and duration. This Crassulaceae plant needs 4-6 hours of direct light every day. Long-term exposure to a low light environment of <2000lux will lead to the decomposition of chlorophyll. However, strong ultraviolet rays of>50000lux at noon in midsummer will cause sunburn spots on the leaves. It is recommended to adopt the lighting strategy of "full sunshine in winter and spring, and half shade in summer and autumn". It is best to use sunshade nets to filter 30%-50% of the light. Improper water management damages the root system. Jade butterflies have typical characteristics of succulent plants-developed water-storing tissues but weak roots. Root rot will be caused when pot soil humidity>60% lasts for 3 days, and the initial stage will be yellowing of base leaves. It is recommended to use the "dipping basin method" for watering: immerse the flower pot in a basin with a water depth of 2 cm once a month, take it out and drain it after 10 minutes. It is better when combined with granular soil with perlite accounting for 30%.
Through systematic maintenance in three dimensions: temperature control, light optimization, and scientific watering, jade butterfly can return to health in 2-3 months. Regularly observe the hardness of the base leaves of the plant (the healthy state should be like an eraser), combined with the application of calcium and magnesium fertilizer once a quarter, can effectively enhance the strength of the cell wall and allow the layers of leaves to regain their jade-like luster.
