Nephrolepis, as a common indoor ornamental leaf plant, is loved by people for its unique wire-like leaves and elegant posture. Many flower enthusiasts have found that the middle of Nephrolepis leaves sometimes turn red during the maintenance process. This not only affects the appearance of the plant but also confuses the maintainers. This article will analyze the reasons for the redness in the middle of Nephrolepis leaves and provide corresponding maintenance skills.
Reasons for the redness in the middle of Nephrolepis fern leaves1. Insufficient light
Nephrolepis is a shade-loving plant. If it is exposed to strong sunlight for a long time, red-brown spots may appear in the middle of the leaves. This is because strong light can destroy chlorophyll, reducing the chlorophyll content in the leaves and causing redness.
2. Excessive watering
Nephrolepis is not tolerant of waterlogging. If watered too much, the roots can rot, leading to red-brown spots in the middle of the leaves. This is because root rot can cause insufficient water and nutrient supply, affecting the normal growth of the leaves.
3. Low air humidity
Nephrolepis prefers a humid environment. If the air humidity is low, red-brown spots may appear in the middle of the leaves. This is because low humidity can cause excessive transpiration in the leaves, leading to insufficient water and nutrient supply.
4. Improper fertilization
Overuse of fertilizer or using fertilizer unsuitable for Nephrolepis can cause red-brown spots in the middle of the leaves. This is because harmful substances in the fertilizer can damage the normal growth of the leaves.
