Why Are My Rhaphidophora Tetrasperma Have Yellow Leaves?

The yellow leaves of indoor potted Rhaphidophora Tetrasperma can be caused by improper watering, dry air, inappropriate light, temperature change, failure to recover after repotting, infection with diseases and pests, improper fertilization or natural aging of Rhaphidophora Tetrasperma leaves.

Humidity Level

High humidity will cause rotten roots of rhaphidophora Tetrasperma, and low humidity will cause water shortage and poor growth of plants. Both of these conditions will cause yellow leaves of Rhaphidophora Tetrasperma.

Soil Discomfort

Rhaphidophora tetrasperma has developed fleshy roots and requires high soil permeability. Cohesive or slightly cohesive soil is unfavorable to its growth. If the soil is not changed for a long time or the soil itself has poor air permeability, it will cause soil hardening, affect the respiration of rhaphidophora tetrasperma root, make Rhaphidophora Tetrasperma grow poorly, and lead to yellow leaves.

• How To Solve

For family potted Rhaphidophora Tetrasperma, the cultivated soil can be mixed with 2 parts of cooked loess and 1 part of honeycomb briquette ash. This can not only ensure the air permeability of the potting soil of Rhaphidophora Tetrasperma, but also meet the fertilizer requirements for growth.

Improper Light

Rhaphidophora Tetrasperma is shade tolerant, but long-term placement of Rhaphidophora Tetrasperma in a shaded environment will affect photosynthesis and turn yellow leaves; At the same time, Rhaphidophora Tetrasperma cannot be placed under strong light, which will cause the leaves of Rhaphidophora Tetrasperma to burn and turn yellow.

Low Temperature

The suitable temperature for the growth of Rhaphidophora Tetrasperma is 20 ~ 25 ℃, and the temperature at night in winter shall not be lower than 10 ℃. The mature plants can withstand the low temperature of 5 ℃ in a short time, and below 5 ℃ is prone to freezing injury, causing the yellow leaves of Rhaphidophora Tetrasperma.

• How To Solve

Before winter, properly control the water of Rhaphidophora Tetrasperma to enhance the cold resistance of Rhaphidophora Tetrasperma. In winter, the roots of Rhaphidophora Tetrasperma should be properly kept warm to enhance the cold resistance of the plant, but we should not put Rhaphidophora Tetrasperma directly on the radiator or next to the air conditioner.

Too Little Fertilization

Iron is a necessary raw material for plants to synthesize chlorophyll. If there is no fertilization for a long time, or the iron element in soil or fertilizer is insufficient, it will affect Rhaphidophora Tetrasperma to synthesize chlorophyll, resulting in Leaf Chlorosis and yellowing.

• How To Solve

If the leaves of Rhaphidophora Tetrasperma turn yellow due to iron deficiency, we should apply alum fertilizer water or spray 0.1-0.3% ferrous sulfate solution.

Poor Ventilation

Rhaphidophora Tetrasperma likes humid environment, but if the ventilation is not smooth and the environment is muggy, the plant grows in turbid air for a long time and has difficulty breathing, resulting in stuffy yellow leaves of Rhaphidophora Tetrasperma.

• How To Solve

We can put the plants on the balcony and windowsill for maintenance, and often open windows for ventilation. Or we can put Rhaphidophora Tetrasperma indoors during the day and move outdoors at night for fresh air.
