What to do if the leaves of the pteris fern turn yellow

Reasons why fern leaves turn yellow

Too dry

There are actually many reasons why the leaves of the phoenix fern turn yellow, and they need to be analyzed based on the specific situation.

First of all, the phoenix fern belongs to the fern family. It prefers shade and is afraid of drought and dry air in the growing environment. Therefore, when the growing environment of the pteris fern is too dry, the leaves of the pteris fern will turn yellow. This may happen because the light is too strong or the watering is not timely.

Temperature is too low

Pteris fern can withstand cold, but the temperature for wintering should not be too low. Generally, the temperature for wintering should be kept above 5℃, and it should be maintained indoors. If the temperature is too low during the winter, the leaves of the pteris fern will turn yellow, and there will be more yellow leaves.

What to do if the leaves of the pteris fern turn yellow

Reasonable lighting

When cultivating phoenix ferns, it is necessary to ensure appropriate lighting. The light in the maintenance environment should not be too strong, and bright scattered light should be the main source. In summer, appropriate shading is required to prevent the sunlight from being too strong and causing the leaves of the fern to curl and turn yellow.

Reasonable watering

Pteris fern likes a humid growing environment. If the air in the maintenance environment is too dry, it will cause yellow leaves. During the growing period of the phoenix fern, the soil needs to be kept moist, and more water should be sprayed around the flowerpot to ensure a high air humidity.

Ensuring winter temperature

When the temperature is low in winter, it is necessary to maintain a suitable wintering temperature to avoid yellowing leaves due to low temperatures. Generally, after the temperature rises in spring, new leaves will slowly grow on the fern. Be careful not to rush to cut off the yellow leaves of the fern, as the yellow leaves can provide nutrients for the new tender leaves.
