What to Do When the Leaves of a Norfolk Pine Turn Yellow
Today, I will explain in detail how to deal with the yellowing of Norfolk Pine leaves and related information about the reasons for the yellowing of Norfolk Pine leaves and the methods for handling green plants. Next, the editor will introduce this.
The reasons for the yellowing of Norfolk Pine leaves are many, such as insufficient light, excessive watering, unsuitable temperature, and infection by diseases and pests. If the leaves of the plant turn yellow, it can be handled according to different reasons. The following is a detailed introduction to the causes and treatment methods for the yellowing of Norfolk Pine leaves.
1. Insufficient Light
Norfolk Pines prefer sunlight. If they grow in a dark environment for a long time, the plant is unable to perform photosynthesis properly, cannot produce chlorophyll, and easily leads to yellowing leaves. In this case, the plant can be moved to a place with sufficient light for cultivation, and proper shading should be provided when direct sunlight is strong.
2. Excessive Watering
Norfolk Pines do not like overly humid environments. If excessive watering causes waterlogging in the potting soil, the roots of the plant can easily rot, unable to absorb water and nutrients, which affects the normal growth of the plant and leads to leaf yellowing. At this point, stop watering and let the potting soil dry out; if there is too much standing water and it cannot dry out in a short time, it is generally recommended to change the soil; normally, water when the soil is dry and water thoroughly.
3. Unsuitable Temperature
When the temperature is too high or too low, the plant will show yellow leaves. It is necessary to provide the plant with suitable growing temperature conditions, such as shading in the summer and keeping it indoors in the winter.
4. Excessive Ventilation
High air flow can cause acute dehydration in the plant, which manifests as yellow leaves. In this case, the plant can be moved to a sheltered area for maintenance, and water can be sprayed to increase the humidity.
5. Diseases and Pests
When the plant is infected with diseases and pests, it will show yellow leaves, and in severe cases, it can lead to the death of the entire plant. Usually, it can be prevented and treated with carbendazim or benzyladenine.
