With the increasing popularity of indoor green plants, kalanchoe is well-liked for its long blooming period and auspicious meaning. Many plant enthusiasts encounter a problem during maintenance: the sudden hollowing of kalanchoe leaves. What is going on? This article will unveil the reasons for the hollowing of kalanchoe leaves and the solutions, helping you grow healthy kalanchoe.
Reasons for the Hollowing of Kalanchoe Leaves1. Improper Water Management
Kalanchoe requires a higher amount of water, but both excessive and insufficient water can cause leaves to hollow. Too much watering can lead to root rot, while too little watering will make the leaves wither.
2. Insufficient Light
Kalanchoe thrives in a sunny environment. If it remains in a dark place for a long time, it can cause the leaves to turn yellow and fall off.
3. Improper Fertilization
Too much or too little fertilizer can affect the growth of kalanchoe. Over-fertilization can cause leaves to turn yellow and fall off, while under-fertilization will make the leaves weak.
4. Pest and Disease Attacks
Pests and diseases are also reasons for the hollowing of kalanchoe leaves, with common pests including aphids and red spiders.
How to Deal with Hollowed Kalanchoe Leaves1. Timely Watering
Kalanchoe prefers a moist environment but attention should be paid to controlling the watering frequency. Generally, water 1-2 times a week to keep the soil slightly moist. If leaves turn yellow and fall off, immediately reduce watering.
2. Moderate Fertilization
During the vigorous growth period, kalanchoe requires moderate fertilization, usually applying a compound fertilizer once a month. Be careful not to over-fertilize to avoid leaf yellowing and falling off.
3. Increasing Sunlight
Place kalanchoe in a sunny area, ensuring it receives at least 4 hours of direct sunlight daily. If sunlight is insufficient, adjust the placement accordingly.
4. Pest and Disease Control
Regularly inspect kalanchoe and take timely measures upon detecting pests and diseases. You can use insecticides and fungicides for prevention and control.
5. Pruning Leaves
Regularly prune kalanchoe leaves, removing sick, weak, and yellowed leaves to help the plant grow.
Hollowing of kalanchoe leaves is a common issue in the maintenance process. Understanding the reasons and taking appropriate measures are key to solving the problem. I hope this article can provide you with help, allowing you to cultivate healthy and beautiful kalanchoe.
