What causes the yellowing of lily of the valley leavesToday's editor introduces the causes of yellowing of lily of the valley leaves and the knowledge of caring for indoor lilies with yellow leaves. The following is a detailed introduction for you:Lilies are perennial herbaceous plants of the Liliaceae family, and lily of the valley is known as the queen of lilies, praised by people. It comes in a variety of colors, including red, pink, white, and many more, looking bright and beautiful, dazzling. Not only is it graceful in appearance, but it also has a faint fragrance, making it very suitable for home care. So, what are the cultivation methods and precautions for lilies of the valley?Firstly, it is important to provide a suitable growth environment, paying attention to climatic conditions and soil environment. The more suitable ecological environment is a cool temperature, humid air, soft light, and loose soil. Lilies of the valley prefer a slightly acidic, fertile soil environment and are not suitable for hard clay soil mixed with sandy soil and decomposed leaf soil. They thrive in rich humus, fertile sandy soil, and well-drained soil, with developed bulbs and bright flower colors.Watering lilies of the valley should not be excessive, just keeping the soil moist is fine. If watered too much, it can easily cause bulb rot. More watering is needed during dry weather, and appropriate foliar application should be done to adjust the humidity in the air. Sufficient watering is required during the flowering period, and there should be no standing water in the pot. In autumn and winter, as the temperature gradually decreases, the amount of watering should be reduced accordingly.Regarding temperature requirements, lilies of the valley have high demands, with the most suitable growth and flowering temperature generally ranging from 16 to 24 degrees Celsius. If the temperature is lower than 5 degrees Celsius or higher than 30 degrees Celsius, growth will stop. Generally, the normal growth temperature for lilies of the valley plants is above 10 degrees Celsius, and growth will gradually stop above 25 degrees Celsius. In winter, the temperature should not be lower than 5 degrees Celsius for an extended period, as it may affect bud development and can even affect flowering in severe cases.What causes the yellowing of lily of the valley leavesWhen lilies of the valley are about to bloom, it is best to provide shading to prevent the leaves from getting too hot. Lilies of the valley require different amounts of sunlight at different growth stages. It is best to shade during the budding stage, and the duration of sunlight should not be too long. When the temperature of the leaves is too high, shading is also necessary to prevent leaf damage. Other growth stages require stronger sunlight, especially during the growth period and flower development stage, where ample sunlight is needed.Lilies of the valley have a high demand for nitrogen and potassium fertilizers. Frequent fertilization is needed during the growing period, but phosphorus fertilizer should be applied less frequently, as excessive amounts can cause yellowing of the leaves. Fertilizers can be synthetic or decomposed liquid fertilizers, and the soil should be loosened before fertilizing to help the roots absorb the nutrients. Phosphorus and potassium fertilizers should be applied before and after flowering to extend the blooming period.The above is a comprehensive explanation of the causes of yellowing of lily of the valley leaves and the reasons for yellowing leaves of indoor lilies, hoping it can help you.
