Kalanchoe is loved by many gardening enthusiasts for its long blooming period and strong vitality. However, during the maintenance process, it is not uncommon for Kalanchoe leaves to turn yellow, which can be confusing for many gardeners. This article will provide a detailed analysis of the reasons for the yellowing of Kalanchoe leaves and offer effective solutions to help your Kalanchoe revitalization.
Reasons for the yellowing of Kalanchoe leaves1. Improper watering
Kalanchoe is sensitive to water demand, and both excessive and insufficient watering can lead to yellowing leaves. Too much watering can cause root hypoxia, affecting plant growth; too little watering can lead to soil dryness and leaf water loss.
2. Insufficient sunlight
Kalanchoe enjoys plenty of sunlight, and if it is kept in a dark environment for a long time, the leaves will turn yellow due to lack of photosynthesis.
3. Improper fertilization
Excessive or insufficient fertilization will affect the growth of Kalanchoe. Over-fertilization can lead to high soil salinity and root damage, while under-fertilization can cause malnutrition and leaf yellowing.
4. Pest and disease attacks
Common pests and diseases include scale insects and red spiders, which absorb the nutrients of Kalanchoe, leading to leaf yellowing.
5. Unsuitable temperature
The suitable temperature for Kalanchoe growth is between 15°C and 25°C. Too high or too low temperatures will affect its growth and cause leaf yellowing.
Solutions to the yellowing of Kalanchoe leaves1. Adjust watering frequency
Water appropriately depending on the dryness or moisture of the soil, and avoid pouring water on the leaves when watering to prevent leaf rot.
2. Increase sunlight appropriately
Place Kalanchoe in a sunny location, ensuring at least 4 hours of direct sunlight every day.
3. Reasonable fertilization
Choose the right fertilizer based on the growth stage of Kalanchoe. During the vigorous growth period, apply nitrogen fertilizer to promote leaf growth; before and after the blooming period, apply phosphorus and potassium fertilizers to promote flowering.
4. Control pests and diseases
Regularly inspect Kalanchoe and deal with pests and diseases in a timely manner, using chemical or physical methods for prevention and control.
5. Control temperature
Place Kalanchoe in a suitable temperature environment to avoid high or low temperatures.
