What to Do When the Leaves of the滴水观音 Turn Yellow
Below is an introduction to the methods and reasons for the yellowing leaves of滴水观音, along with some plant cultivation tips. Let's delve into the details.
The yellowing of滴水观音 leaves may be due to problems during maintenance, such as insufficient light, improper watering and fertilizing, unsuitable temperature, and soil deterioration. These issues can lead to the leaves becoming枯黄 and even falling off. Let's discuss these in detail.
1. Insufficient Light
滴水观音 loves sunlight and is shade-tolerant. If kept in a dark environment for a long time without sunlight exposure, the leaves will become枯黄 and wilt. Move it to a shady area with weak light, gradually increase light exposure after recovery, and provide shade during the summer when strong UV radiation can burn the leaves.
2. Improper Watering
Insufficient water can cause the leaves to become dry and枯黄. Water should be added based on the dryness of the potting soil, with 2-3 waterings per week, and once a day in summer to prevent rapid evaporation and dehydration of the plant leaves. Excessive watering can lead to damp soil that is not conducive to root growth, causing the leaves to turn yellow. Accumulated water should be drained and the plant placed in a cool, well-ventilated area to promote rapid evaporation. Avoid heavy watering during continuous rainy weather and the plum rain season when the air humidity is high.
3. Improper Fertilizing
Lack of nutrients during the growing period or excessive fertilizer concentration can cause the leaves to become枯黄. Fertilize every 15-30 days with a dilute solution of fertilizer. After over-fertilizing, water should be added to dilute the fertilizer. If the leaves are extensively枯黄 and falling off, change the potting soil.
4. Unsuitable Temperature
滴水观音 prefers a warm environment. When the temperature exceeds 35°C, water should be sprayed around the plant to cool it down. When the temperature is below 10°C, the plant grows slowly and should be moved to a warm indoor area to help it survive the winter. Otherwise, frost damage can easily cause the leaves to become枯黄 and the plant to wilt.
5. Soil Deterioration
Over time, the soil can lose its fertility and become compacted, which is not conducive to root growth. Replace the potting soil every 1-2 years, choosing an appropriate pot size based on the plant's size. Use a mixture of decomposed leaf soil, peat soil, and fine sand as the growing medium, and add a moderate amount of cake fertilizer.
6. Dust on Leaves
Accumulation of dust on the leaves can hinder photosynthesis and fail to provide adequate nutrients to the plant, causing the leaves to become yellow and dry. Clean the leaf surface with a damp cloth and spray water on the leaves regularly.
7. Pests and Diseases
Infestation by red spiders can cause the leaves to turn yellow and fall off. Remove the affected leaves promptly to promote the growth of new ones. Spray pesticides to prevent and control pests and diseases, once a week until the problem is resolved.
The above is a comprehensive explanation of what to do when the leaves of滴水观音 turn yellow, and the reasons and solutions for yellowing leaves. I hope it can help solve your problems with green plants.
