Kalanchoe, as a popular indoor potted plant in recent years, has won the favor of many gardening enthusiasts with its long blooming period and easy maintenance. During use, some gardeners may find that the leaves of Kalanchoe become sticky and oily, which not only affects the appearance but may also have adverse effects on the growth of the plant. This article will uncover the reasons for the oily leaves of Kalanchoe and provide solutions to help you cultivate healthy and beautiful Kalanchoe.
Reasons for Oily Leaves on Kalanchoe1. Low air humidity
Kalanchoe is native to Africa and prefers a warm and humid environment. If the indoor air humidity is low, the leaves of Kalanchoe are prone to becoming sticky and oily.
2. Improper watering
Both excessive and insufficient watering can cause the leaves of Kalanchoe to become sticky and oily. Excessive watering leads to root hypoxia and the production of sticky fluid, while insufficient watering causes the leaves to lose water and secrete sticky fluid.
3. Improper fertilization
Excessive fertilization or improper fertilization can also lead to oily leaves on Kalanchoe. Excessive fertilization damages the plant's roots, producing too much sticky fluid, while improper fertilization may result in poor absorption and secretion of sticky fluid.
4. Leaf diseases and pests
Leaf diseases and pests are also among the reasons for the oily leaves of Kalanchoe. Pests such as red spiders and scale insects extract plant sap, leading to sticky and oily leaves.
Methods to Fix Oily Leaves on Kalanchoe1. Increase air humidity
Using a humidifier or placing hydroponic plants can increase indoor air humidity, which helps to alleviate the oily leaf phenomenon of Kalanchoe.
2. Adjust watering frequency

3. Fertilize moderately
According to the growth stage of Kalanchoe, fertilize appropriately and water promptly after fertilizing to avoid fertilizer residue.
4. Remove diseases and pests

Methods to Prevent Oily Leaves on Kalanchoe1. Maintain good ventilation
A good ventilation environment helps to reduce air humidity and prevent the oily leaf phenomenon of Kalanchoe.
2. Prune regularly
Regular pruning of Kalanchoe to remove diseased and weak branches and leaves helps to enhance the plant's disease resistance.
3. Choose the right soil
Choosing soil with good breathability and drainage helps the healthy growth of roots and reduces the oily phenomenon.
