What should I do if the leaves droop?
Anthurium is a popular indoor ornamental plant, and its leaf droop problem often troubles growers. This paper uses on-site maintenance experience combined with botanical principles to systematically sort out the five key maintenance points to help you quickly diagnose and restore plant health. The abnormal temperature influence of environmental factors on the drooping of Anthurium leaves is 18-28℃, which is the ideal growth temperature range of Anthurium. When the temperature is>35℃, the transpiration of the plant is unbalanced; when the temperature is <10℃, a freezing injury reaction will be triggered, which will lead to wilting and sagging of the leaves. It is recommended to use sunshade net + spray to cool down in summer, and use heating pads to maintain ground temperature in winter. If the light intensity is inappropriate, Anthurium is suitable for a scattered light environment of 15,000 - 20,000 Lux. Burn on the leaf surface occurs after more than 3 hours of direct exposure to strong light, which is characterized by curling and drooping leaves. The plant can be moved 1.5 meters away from the east-facing window, or adjusted using a gauze curtain with a light transmittance of 40%. The main points of daily maintenance of Anthurium are scientific and water management adopts the watering principle of "seeing dry, seeing wet": keep the substrate humidity at 60% in summer and reduce it to 40% in winter. It is recommended to use a TDS test pen to ensure that the EC value of irrigation water is <0.5mS/cm. Rinse the substrate with purified water monthly to prevent salt accumulation. Accurate humidity control requires maintaining 70-80% air humidity. Double-layer humidity management can be used: place a moss moisturizing layer on the bottom of the basin, and operate with an ultrasonic humidifier for 3-4 hours a day (avoid night hours). Pay attention to the need to strengthen ventilation after spraying water on the leaves to prevent leaf spot disease. When changing pots every two years in the substrate improvement plan, the substrate is prepared according to the ratio of coconut bran: peat soil: perlite =4:3:3, and 10% pine phosphorus is added to improve air permeability. Using rooting agent (IBA 500ppm) to irrigate roots after changing pots can shorten the pot application period by about 40%.
By systematically adjusting the three elements of temperature, light and humidity, and cooperating with scientific water and fertilizer management, most Anthurium leaf droop problems can be improved within 2-3 weeks. It is recommended to establish a maintenance log to record daily environmental parameters and plant state changes, and gradually form a personalized maintenance plan.
