What Causes the Tips of Calla Lily Leaves to Turn Yellow
The editor will share with you the reasons why the tips of calla lily leaves turn yellow and some small experiences in green plant maintenance regarding the solutions for yellowing leaves, let's take a look together!
During the cultivation of calla lilies, it is common to encounter the problem of yellowing leaves. We must identify the cause and address it accordingly, or it may harm the entire plant. Next, I will specifically introduce the reasons for yellowing calla lily leaves and the treatment methods.
1. Improper Watering
Too much or too little watering will affect the plant's root system's ability to absorb nutrients, leading to yellowing leaves. You can pinch the soil; if there is slight seepage, it is too damp. Remove the plant, trim the rotten roots, and then replant it in new soil. If it doesn't clump, it indicates a lack of water, and immediate watering is needed.
2. Inappropriate Temperature
The optimal temperature for plant growth is between 15-25°C. When the temperature is above 25°C or below 5°C, the plant enters dormancy, and yellowing leaves often occur. During hot summers, provide appropriate shading and spray water to cool down. Before winter temperatures drop, move the plant indoors and control the room temperature appropriately to effectively avoid yellowing.
3. Improper Light Exposure
Calla lilies need to receive more than 3 hours of sunlight per day. If there is insufficient light, yellowing leaves may appear. You can place the plant in a bright location and provide appropriate shading when the light is intense.
4. Fertilization Issues
Too little fertilization results in a lack of nutrients for the plant, while too much fertilization can cause root burn from accumulated fertilizer, leading to yellowing leaves. If there has been no fertilization for a long time, it is necessary to apply additional fertilizer promptly to supplement nutrients. Dilute phosphorus fertilizer to 1500 times the liquid and water it into the soil in small amounts, taking care not to spray it on the leaves, as this may cause more yellowing. If too much fertilizer is used, stop fertilizing and consider changing the soil if the situation is severe.
5. Environmental Pollution
Plants prefer clean air. Long-term exposure to abnormal air such as smoke and cooking oil fumes can lead to yellowing leaves. It is recommended to keep the plant away from the kitchen and in a well-ventilated area.
The above sharing on the reasons why the tips of calla lily leaves turn yellow and the specific introduction to the solutions for yellowing leaves hope to bring some knowledge about flowers to green plant enthusiasts.
