However, in the process of caring for asparagus fern, sometimes the problem of yellowing leaves occurs. Let’s learn together why the leaves of Chinese bamboo turn yellow. How to solve it?

1. Cause Analysis

1. Lighting issues

Asparagus fern is a semi-shade plant and should not be exposed to strong light for a long time, especially direct sunlight in summer, which will cause the chlorophyll in the leaves to decrease and the leaves to turn yellow. The solution is to move the asparagus fern to a cool place and replenish water regularly. When the sunlight is weak in winter, you can get some sun exposure, but make sure the temperature is no lower than 5 degrees Celsius.

2. Watering problem

Too much or too little watering may cause the leaves of asparagus fern to turn yellow. The correct principle of watering is to water when the soil is dry and keep the soil moist but not waterlogged. In dry weather, spray water on the leaves in the morning and evening to increase humidity.

3. Fertilization issues

Improper fertilization can also cause yellowing leaves. Excessive fertilization will cause the asparagus fern to grow too tall, while lack of fertilizer will cause the leaves to turn yellow. Nitrogen-containing fertilizers should be selected, and the amount of fertilizer applied should be controlled to avoid overdosage.

4. Smoke and dust pollution

Asparagus fern is sensitive to smoke and harmful gases, and long-term exposure to a polluted environment will cause its leaves to turn yellow. The solution is to keep asparagus fern away from pollution sources and spray water to clean the leaves regularly.

5. Pests and diseases

Pests and diseases are also one of the reasons why asparagus fern leaves turn yellow. Once pests are found, manual removal or drug control measures should be taken in time.

2. Solution

Light: Asparagus fern prefers a semi-shaded environment and should be placed in a place with sufficient diffuse light, avoiding direct sunlight, especially the scorching sun in summer. During the flowering period, attention should be paid to wind and rain protection and good ventilation should be maintained.

Humidity and watering: Asparagus fern likes a humid environment, but avoid excessive watering which may cause root rot. Water every 3-5 days in spring and autumn, every 2 days in summer, and reduce the amount of watering in winter. When watering, make sure the water temperature is close to the ambient temperature.

Temperature: The suitable growth temperature for asparagus fern is 15℃-25℃. The growth will slow down in high temperatures in summer. The temperature in winter should be kept above 10℃ to avoid frost damage.

Soil: Asparagus fern likes loose, fertile and well-drained soil. You can choose humus soil, peat soil, etc., and add appropriate amount of organic fertilizer .

Fertilization: Although asparagus fern is not a fertilizer-loving plant, appropriate fertilizer will help its growth. In spring and summer, nitrogen fertilizer is mainly used, and thin liquid fertilizer is applied once a month. After the plants are established, control fertilization appropriately to avoid excessive growth.

The above is an introduction to the reasons and solutions for the yellowing of asparagus fern leaves. You can refer to it to see if you have failed to take care of these factors when caring for asparagus fern in your daily life.
