How to deal with white mold on the leaves of Kalanchoe?

Kalanchoe is a popular houseplant known for its long blooming period and easy care. However, when white mildew that resembles chalk dust appears on the leaves of kalanchoe, this is often a sign of powdery mildew, a plant disease caused by fungi. If steps are not taken quickly to treat it, this fungal infection can spread quickly and cause extensive damage to the plant. Let’s learn in detail how to deal with white mold on the leaves of Kalanchoe?

1. Causes of white mold on Kalanchoe

1. Environmental factors

High temperature and high humidity: These environmental conditions tend to promote the growth of bacteria and fungi, making the Kalanchoe more vulnerable.

Hot and stuffy: An environment lacking fresh air is conducive to the growth of bacteria and increases the risk of powdery mildew.

2. Improper fertilization

Applying excessive nitrogen fertilizer: Nitrogen fertilizer promotes the growth of branches and leaves, but if it is excessive, it will cause the branches and leaves to be too dense, affecting light and ventilation, thus creating conditions for the occurrence of powdery mildew.

2. Solutions to powdery mildew

1. Prune diseased leaves

Prune off severely infected leaves promptly to reduce the spread of the disease.

2. Rational use of drugs

Use an appropriate fungicide for treatment, such as 600 times diluted 65% mancozeb wettable powder , and spray once every 4 to 5 days.

In short, the appearance of white mold on Kalanchoe is usually a symptom of powdery mildew, which is closely related to the maintenance methods and environment. In order to reduce the occurrence of diseases, the above measures should be taken. And regularly check the health of the plants to detect and deal with powdery mildew problems in a timely manner.
