What to Do When the Tips of Ficus Lyrata Leaves Turn Black and Dry
As a popular choice for indoor greenery, Ficus lyrata is loved for its elegant shape and air-purifying properties. However, discovering blackened and dried leaves can often leave plant enthusiasts at a loss. This article will systematically analyze the causes and solutions for abnormal leaf conditions in Ficus lyrata from three dimensions: light adjustment, water management, and temperature control.
Tips for Light Adjustment
Identifying and Dealing with Insufficient Light
When the lower leaves of the plant gradually turn yellow and fall off, and the new leaves become lighter in color, it indicates a lack of light. It is recommended to gradually move it to an east-facing windowsill to receive 3-4 hours of soft morning light daily, avoiding direct exposure to strong noon sunlight.
Emergency Measures for Sunburn
Brown burn spots on the leaf tips are typical symptoms of sunburn. You can immediately cover it with a white gauze curtain to filter the light, and use a spray bottle to mist the leaves for补水, twice a day for 3 days.
Scientific Water Management
Reasonable Watering Frequency
In spring and autumn, maintain a watering cycle of 5-7 days, reduce it to 3-4 days in summer but decrease the amount of water per watering. In winter, use the "dry-wet" method, watering only when the top 2cm of soil is dry.
Drainage and Ventilation Management
Place a 3cm thick layer of ceramsite at the bottom of the pot, and combine it with a substrate containing 30% perlite to effectively prevent waterlogging. After watering, turn on a fan to promote air circulation and accelerate moisture evaporation.
Key Points for Temperature Control
Winter Temperature Control
When the ambient temperature is below 8°C, it is recommended to use a double-layer insulation method: cover the outside with a transparent plastic bag (leave ventilation holes), and wrap the inside with non-woven fabric, combined with a foam box pad to insulate the pot.
Daily Temperature Maintenance
When caring for the plant in an air-conditioned room, avoid placing it directly in front of the air outlet. Use a thermometer and hygrometer to monitor in real-time, maintaining an ideal temperature range of 18-28°C, and keeping the day-night temperature difference within 5°C.
By adjusting light, precise water control, and temperature management, combined with applying chelated iron fertilizer once a month to prevent yellow leaves, and regularly checking the soil pH (maintaining a slightly acidic level of 5.5-6.5), you can revitalize the Ficus lyrata. It is recommended to establish a care log to record the plant's changes after each adjustment, gradually mastering a personalized care plan.
