Causes and treatments for yellowing water lily leaves

1. Insufficient light

1. Reason: Water lilies prefer an environment with plenty of sunlight. If they are in an environment without light for a long time, they will have yellow leaves because they cannot photosynthesize.

2. Treatment method: At this time, you should move it to an environment with better lighting conditions and let it receive more light to help it recover.

2. Lack of water

1. Reason: It has a relatively large demand for water and has certain requirements for water quality. Long-term water shortage or poor water quality during the growing period will cause its leaves to turn yellow.

2. Treatment method: Control the water content, ensure sufficient water volume and clean water quality. Do not use polluted or poor-quality water for breeding. Changing the soil and water in time can effectively avoid the problem of yellowing leaves.

3. Improper fertilization

1. Reason: It needs certain nutrients during the growth period and needs proper fertilization. If too little fertilizer is applied for a long time, it will have yellow leaves due to lack of nutrition.

2. Treatment method: Use thin fertilizer once every half a month during the growth period of water lilies, and reduce fertilization to once a month in autumn and winter. If the problem of yellowing leaves has already occurred, you can apply phosphorus and potassium fertilizers at intervals of 10 days. Do not use large amounts of fertilizer until the leaves improve.
