How to deal with yellowing leaves of asparagus fern

1. Excessive watering

1. Reasons

Everyone knows that asparagus fern likes a humid environment, but this does not mean that you have to water it all the time. The correct way to water asparagus fern is to keep the soil in the pot moist and not water it unless it is dry. When you water it, water it thoroughly.

2. Solution

If you overwater, you can stop watering temporarily and instead just spray water on the leaves to keep the asparagus fern moisturized.

2. Too much light

1. Reasons

Asparagus fern is a semi-shade plant. As you can imagine, if it is placed under strong light, it will definitely be burned and its branches and leaves will turn yellow.

2. Solution

Move the flowerpot to a cool place and spray water on the branches and leaves to increase humidity. The evaporation of water will take away a certain amount of heat, which can cool down the asparagus fern.

3. Improper temperature

1. Reasons

Asparagus fern has a temperature suitable for its growth, generally speaking, the most suitable temperature is between 12-18℃. If it stays in a low temperature environment for a long time, it will be frostbitten, which will lead to slow metabolism and cause the leaves to turn yellow.

2. Solution

The solution is to keep asparagus fern in an environment of about 15 degrees and provide appropriate diffused weak light.

4. Improper fertilization

1. Reasons

Applying too much or too little fertilizer will cause some discomfort to asparagus fern. If there is too much fertilizer, it will cause seedling burn. If there is too little fertilizer, it will lead to subsequent nutritional deficiencies in asparagus fern and cause the leaves to turn yellow.

2. Solution

If too much fertilizer is applied, it is recommended to change the pot immediately and transplant the asparagus fern to a new environment. Or water immediately and move the plant to a bright, well-ventilated area.

If there is not enough fertilizer, it is recommended to add an appropriate amount of chemical fertilizer to provide the nutrients needed by asparagus fern.

5. Pests and diseases

1. Reasons

Scale insects are the most common pests in asparagus fern cultivation. If left unattended after the scale insects appear, the nutrients in the asparagus fern will be absorbed by the scale insects, which will also cause the leaves to turn yellow.

2. Solution

When scale insects are found, they should be wiped off with a wet cloth in time.

When the situation is serious, you should go to the pharmacy to buy medicine for prevention and treatment, and change the potting soil in time.

When repotting the soil, you can cut off the old and damaged roots to reduce nutrient consumption.

6. Gas poisoning

1. Reasons

Asparagus fern is very afraid of smoke and dust. If it is often attacked by harmful gases such as smoke and dust, the asparagus fern will show poisoning symptoms such as yellowing of branches and leaves. In addition, factors such as television radiation and fire can also cause the leaves of asparagus fern to turn yellow.

2. Solution

If this happens, move the flower pot from its original location in time and increase the work of watering and dusting the leaves. Wipe off the dust on the leaves of asparagus fern, or keep it away from radioactive items such as televisions.
