What should I do if the lily leaves wilted?
As a common ornamental flower, lily leaves wilting and drooping are typical signs of maintenance problems. This article focuses on the four major causes of lily leaf wilting, systematically analyzes the corresponding scientific treatment plans, and helps your lilies regain their vitality through both environmental regulation and maintenance management. Light regulation: Plan to improve the photosynthetic efficiency of lily flowers 1.1 The harm of insufficient light is manifested in when the light is less than 6 hours a day, lily flowers will appear long and slender stems and large leaf spacing. Long-term lack of light will lead to the inhibition of chlorophyll synthesis, which is manifested by thin, soft and yellowing leaves, and ultimately a wilted state. 1.2 Scientific Filling Light Operation Guide Full sunshine maintenance can be accepted in spring and autumn, and a sunshade net needs to be built between 11 and 15 o'clock in summer. It is recommended to place a south-facing sill indoors and use a light meter to ensure that the light intensity is ≥30000 lux. In winter, you can use it with plant fill light to maintain daily light duration for 8-10 hours. Environmental optimization: Key points for air circulation control 2.1 Ventilation system construction standards It is most appropriate to maintain the air circulation speed of 0.3-0.5m/s, which can be achieved by opening windows for convection or circulating fans. Pay attention to avoid direct draft wind, and keep the spacing between potted plants more than 30cm. Regularly detect with anemometer, and the number of air changes per hour in high temperature seasons is ≥6. 2.2 Collaborative management of temperature and humidity combines thermohygrometer monitoring to maintain a daytime temperature of 18-25℃/12-18℃ at night. The air humidity is optimal when 60-70%, which can be regulated by an atomizing humidifier. When drying at high temperatures, it is recommended to spray once in the morning and evening to avoid flowers. Water and fertilizer management: Implementation plan for precise supply 3.1 The intelligent watering system uses a soil moisture detector to replenish water when the soil moisture content of the top 5 cm is less than 30%. The growth period follows the principle of "seeing dry, seeing wet". The soil moisture is maintained at 60% during the flower bud period, and the dormant period is reduced to 20%. It is recommended to use a long-spout watering pot to slowly penetrate along the edge of the basin. 3.2 Scientific fertilization practices apply slow-release fertilizer with a ratio of 1:2:2 per month, and the single amount shall not exceed 15g/pot. If fertilizer damage is found, immediately irrigate the roots with clean water for three times, and if severe, replace the disinfection substrate (soak in 800 times carbendazim solution for 30 minutes). After topdressing, EM bacterial solution needs to be combined to regulate soil microecology.
Through the above-mentioned systematic adjustments in the three dimensions of light regulation, environmental optimization, and water and fertilizer management, and regular observation of leaf hardness changes (normal leaf curvature should be ≤45°), wilted lilies can usually be restored to vitality in 2-3 weeks. It is recommended to establish a maintenance log to record daily environmental parameters and plant status to form a personalized maintenance plan.
