Reasons for and Solutions to Yellowing Leaves on Chinese Evergreen

Chinese evergreen (Aglaonema modestum) is also called Chinese evergreen grass, and because its stems are upright and jointed with obvious internodes, it is also called bamboo-joint Chinese evergreen. Its leaves are broad and glossy, emerald green in all four seasons, and it is especially shade-tolerant. It can be cut to make foliage bonsai or used as a foil for flower arrangements, decorate the environment, and can also be used for potted plants to embellish halls and rooms.

Dense branches and leaves is one of the reasons that cause yellowing leaves on Chinese evergreen. Chinese evergreen is a plant with relatively strong branch and leaf growth, especially the root system, which will sprout many branches and leaves. If the branches and leaves are too dense, it will cause poor air circulation and cause the lower leaves to turn yellow.

Soil that is not breathable is also one of the reasons. Chinese evergreen is a plant with fleshy roots and needs well-drained, breathable soil. Otherwise, it will affect the healthy growth of the plant and cause the leaves to turn yellow.

Light and temperature are important factors affecting the leaves of Chinese evergreen. If it is placed in a shaded indoor area for a long time, Chinese evergreen will not receive suitable light, and the lower leaves will turn yellow, wither, and dry up. Temperature refers to the low temperature in winter, because low temperatures easily cause freezing damage; when the plant is frozen, the leaves turn yellow.

Improper watering mainly means insufficient water. Because Chinese evergreen likes sufficient water during its growth period; otherwise the leaves will look listless and turn yellow. Unsuitable fertilization mainly refers to a lack of fertilizer. A lack of fertilizer will cause the leaves of Chinese evergreen to turn yellow, become fragile in texture, and quickly age and wilt.

If the leaves are contaminated, they will also turn yellow. If fertilizer is accidentally sprinkled on the leaves during fertilization, or if soil and dust stick to them, it may cause the leaves to turn yellow.

If the Chinese evergreen plant looks very dense, it is best to prune it, appropriately cutting off some branches and leaves and letting the leaves grow freely, which can make them emerald green and full of luster.

When Chinese evergreen is growing, slightly acidic sandy soil is best, so that the plant's root system will grow. For the flower pot, it is also best to choose one with strong breathability, and some tiles can be placed at the bottom of the pot.

As for light, indoor cultivation is still best, but it is best to have a place with diffused light, and it should often be placed outdoors for maintenance for a period of time, but be careful not to place it under strong light to avoid scorching. As for temperature, mainly in winter, keep the room temperature above 5°C. When moving it outdoors in spring, appropriately cut off dead leaves.

Water should be sufficient. In relatively dry weather, it is also necessary to spray water on the Chinese evergreen plant in time. When fertilizing, some nitrogen fertilizer can be applied during the budding period to make the leaves grow well; after that, phosphorus and potassium fertilizer should be the main type to prevent the plant from growing leggy.

To prevent the leaves of Chinese evergreen from turning yellow due to contamination, the leaf surface can be cleaned frequently.

Leaf spot disease. This disease occurs on the leaves of Chinese evergreen, and in weather with high humidity, this disease is prone to occur. At first, the disease spots are small brown spots, with a water-soaked, faded green border, and they expand in concentric rings, round to oval, with brown edges and grayish-white centers. Later, dark brown mold spots appear in the center of the disease spots, and under humid conditions they become a dark brown mold layer. The method to prevent and control this disease is to remove diseased and residual leaves in time;
