In the vast gardens and water landscapes of our country, Nymphaea, with its elegant posture and fresh atmosphere, has become a favorite of many families and parks. Many flower friends have found that the leaves of Nymphaea sometimes turn purple during the maintenance process, which not only affects its appearance but also causes concern about its growth condition. What is the reason for the purple leaves of Nymphaea? How should we maintain it?
Reasons for the purple leaves of Nymphaea1. Insufficient lighting
Nymphaea prefers an environment with plenty of light. If it is kept in a dark place for a long time, it will cause the leaves to turn purple. This is because insufficient light can lead to a decrease in the synthesis of chlorophyll in the leaves, making the leaves appear purple.
2. Water quality issues
Nymphaea has high requirements for water quality. If the water is too hard or contains more heavy metal ions, it will affect its normal growth and cause the leaves to turn purple. Long-term use of unfiltered water for irrigation may also cause the leaves to turn purple.
3. Improper application of fertilizer
Excessive application of fertilizer or improper application of fertilizer can damage the roots of Nymphaea, thus affecting its growth and causing the leaves to turn purple. If the leaves are not watered in time after fertilization, the fertilizer will remain on the leaves, causing them to turn purple.
4. Pest and disease attacks
Nymphaea is prone to attacks from pests and diseases, such as powdery mildew and leaf spot. These pests and diseases can cause the leaves to turn purple, and in severe cases, even lead to the death of the plant.
Maintenance skills for purple leaves of Nymphaea1. Increase lighting appropriately
Place Nymphaea in a place with plenty of light, ensuring at least 4 hours of direct sunlight every day. In winter, artificial light sources can be used to supplement lighting appropriately.
2. Improve water quality
Change the water regularly to ensure it is clean. If the water is too hard, water-quality improving agents for aquariums can be used for treatment.
3. Apply fertilizer rationally
When applying fertilizer, follow the principle of "apply thin fertilizer frequently" and avoid excessive fertilization. During the period of vigorous growth, the application amount of nitrogen fertilizer can be increased appropriately to promote leaf growth.
4. Prevent pests and diseases
Regularly check the growth condition of Nymphaea and deal with pests and diseases in a timely manner. Biopesticides or low-toxicity pesticides can be used for prevention and control.
5. Maintain a good growing environment
Keep the air flowing, avoid overcrowding the plants, and trim the withered leaves appropriately, which help the plants grow healthily.
There are many reasons for the purple leaves of Nymphaea, but as long as we understand its growth habits and take corresponding maintenance measures, we can make Nymphaea glow with charming luster. This also reminds us that when maintaining plants, we should pay attention to their growing environment and provide good growing conditions for them.
