Heigu Xiang, as a common ornamental plant, is loved by flower enthusiasts for its unique shape and elegant temperament. During the maintenance process, the yellowing of the top leaves of Heigu Xiang often plagues many enthusiasts. This article will provide you with a detailed analysis of the reasons for the yellowing of the top leaves of Heigu Xiang and the solutions to the problem, helping you easily deal with this issue.
Reasons for the yellowing of the top leaves of Heigu Xiang1. Improper water management
Heigu Xiang is sensitive to water demand, and excessive or insufficient water can cause the leaves to turn yellow. Excessive watering can lead to oxygen deficiency in the roots, thus affecting the normal growth of the plant; insufficient watering will cause the soil to dry out, preventing the roots from absorbing enough water and resulting in yellowing leaves.
2. Insufficient lighting
Heigu Xiang prefers ample scattered light. If it is kept in a dark environment for a long time, the leaves are prone to yellowing. Uneven lighting can also cause the leaves to turn yellow.
3. Soil problems
Soil that is too compact or too acidic can affect the growth of Heigu Xiang. Soil compactness can hinder root respiration, leading to yellowing leaves; excessively acidic soil can affect the plant's nutrient absorption.
4. Improper application of fertilizers
Overuse of fertilizers or the use of inappropriate fertilizers can cause the leaves of Heigu Xiang to turn yellow. Excessive fertilization can lead to high soil salinity, affecting the plant's normal growth; the use of inappropriate fertilizers may prevent the plant from absorbing enough nutrients.
5. Pest and disease attacks
Heigu Xiang is susceptible to pest and disease attacks, such as aphids and red spiders. These pests extract nutrients from the plant, causing the leaves to turn yellow.
