What Causes the Yellowing of Monstera Deliciosa Leaves
As a popular indoor ornamental plant, Monstera Deliciosa is loved for its unique split-leaf shape. However, many plant enthusiasts often encounter issues such as yellowing leaves and blackened stems during the maintenance process, which are often closely related to the details of daily care.
Three Main Causes of Yellowing Monstera Deliciosa Leaves
Root Suffocation Due to Soil Compaction
The fleshy roots have high soil requirements. When the substrate becomes compacted, the roots cannot breathe or absorb nutrients properly. It is recommended to change the specialized nutrient soil every two years, mixing leaf mold soil, coconut fiber, and perlite in a 4:3:3 ratio, with a 3cm layer of ceramsite at the bottom of the pot for drainage.
Imbalance in Water Management
In spring and autumn, use the "dry-wet" method, watering thoroughly when two sections of the finger inserted into the soil feel dry. In summer, coordinate with 85% air humidity, and in addition to misting the leaves in the morning and evening, place wet pebbles in the saucer. In winter, control watering to once or twice a month, with the water temperature matching the room temperature.
Disrupted Light Intensity
Bright scattered light is the best choice, and direct sunlight at noon should be blocked in the summer. If kept in a dark place for a long time, the leaves will fade and become thin; continuous exposure to strong sunlight will result in brown sunburn spots. It can be placed 1.5 meters away from an east-facing window to ensure 4-6 hours of soft light exposure daily.
Solutions for Blackened Stems
When black lesions are found on the stem, immediately remove the pot to check the roots: 1. Cut off the blackened and rotten roots, retaining the healthy white root sections. 2. Soak in a fungicide solution (Carbendazim 800 times) for 30 minutes. 3. Replace with disinfected coarse sand to regenerate roots. 4. Bag it to maintain humidity and place it in a ventilated environment at 25°C.
In daily maintenance, using EM bacteria solution monthly can effectively prevent root rot. Regularly rotating the pot ensures even exposure to light, and using slow-release fertilizer can enhance the plant's resistance. By mastering the correct maintenance methods, Monstera Deliciosa can continue to showcase its unique leaf art.
