Red掌, scientifically known as Anthurium, has become a popular indoor foliage plant in recent years. Its leaves are green and its flowers are unique, making it highly ornamental. However, during daily maintenance, many plant enthusiasts encounter the issue of the center of the red掌 leaves drying up and forming holes, severely affecting the plant's appearance. So, what is the reason for the dried and holed center of the red掌 leaves? How should we address this issue?
I. Cause Analysis1. Overwatering or underwatering: Watering is a key factor in the maintenance of red掌. Excessive watering can lead to waterlogging in the roots, preventing normal respiration and affecting plant growth. Insufficient watering can cause leaf dehydration and drying. Particularly the central part of the leaves, due to its central position, is more prone to drying and holes when moisture is insufficient.2. Insufficient lighting: Red掌 prefers a semi-shaded environment, but prolonged insufficient lighting can weaken photosynthesis, failing to provide adequate nutrition for the leaves, leading to dried and holed leaves.3. Pest and disease attacks: Red掌 is prone to pest and disease attacks in hot and humid conditions, such as aphids and red spiders. These pests consume the leaf sap, causing dried and holed leaves.4. Improper fertilization: Excessive or improper fertilization can damage the roots of red掌, affecting normal plant growth. Especially excessive nitrogenous fertilization can make leaves too thick and prone to breaking.II. Remedial Measures1. Adjust watering: According to the growth needs of red掌, adjust the amount of water appropriately. When watering, pay attention to the soil moisture, keeping it slightly moist. Avoid waterlogging and prevent the soil from becoming too dry.2. Increase lighting: While ensuring that red掌 is not exposed to direct strong sunlight, increase lighting appropriately. Place the plant in a semi-shaded environment, allowing it to receive ample scattered light.3. Control pests and diseases: When pests and diseases are detected, take measures to control them promptly. You can spray an appropriate amount of insecticide or use an alcohol cotton ball to wipe the leaves to kill the pests.4. Reasonable fertilization: According to the growth needs of red掌, fertilize appropriately. Avoid excessive application of nitrogenous fertilizers and increase the application of phosphorus and potassium fertilizers to promote plant growth.5. Prune diseased leaves: For leaves that have already developed dried and holed areas, prune them promptly. This reduces the plant's nutrient consumption and helps the plant recover growth.In summary, the main reasons for the dried and holed center of red掌 leaves are improper watering, insufficient lighting, pest and disease attacks, and improper fertilization. By adjusting watering, increasing lighting, controlling pests and diseases, reasonable fertilization, and pruning diseased leaves, we can effectively prevent and address the issue of dried and holed leaves in red掌. During maintenance, we should carefully observe the plant's growth conditions, address issues promptly, and take appropriate measures to ensure the healthy growth of red掌.
The comprehensive knowledge shared above on the causes and remedies for the dried and holed center of red掌 leaves, hoping it helps you.
