What to Do When the Leaves of the Chives Peony Turn Yellow
The yellowing of leaves in chives peony is a common challenge in maintenance, but it can be fully restored through scientific diagnosis and targeted treatment. This article will systematically analyze the six major causes and provide practical treatment solutions to help you cultivate chives peony with lustrous leaves and abundant flowers.
Analysis of the Six Major Causes of Yellowing Leaves in Chives Peony
1. Natural Metabolic Yellowing
Periodic yellowing of the bottom old leaves is part of normal metabolism. It is recommended to clear the withered yellow leaves once a month to maintain ventilation and light for the plant. If the new leaves continue to turn yellow, be vigilant for pathological factors.
2. Root Damage Inducing Yellowing
Repotting damage, pest infestation, etc., can lead to absorption dysfunction. You can determine root issues by observing whether the new leaves turn yellow. Damaged roots need to be disinfected with a solution of 800 times the concentration of carbendazim.
3. Nutritional Imbalance Yellow Leaf Symptoms
Lack of nitrogen causes uniform yellowing of old leaves, while lack of iron results in loss of green between the veins of new leaves. It is recommended to apply a special flower fertilizer every half month during the growing season and add phosphorus and potassium fertilizers during the bud formation period.
4. Temperature Stress Causing Yellowing
When temperatures drop below 5°C in winter, cell membranes are damaged, appearing as purple-red patches that turn yellow. Continuous high temperatures above 35°C in summer will accelerate transpiration, requiring the use of shading nets.
5. Sunburn Yellow Spots
Direct sunlight at noon can cause scorching spots on the leaves. It is recommended to use a 50% shading rate sunscreen net or move it to an east-facing balcony for soft lighting.
6. Poor Ventilation Complications
Compact environments can trigger pests like spider mites, appearing as spotted yellow patches. Maintain a plant spacing of over 30 cm and open windows for ventilation three times a week.
Systemic Treatment Plan for Yellow Leaves in Chives Peony
Emergency Treatment for Physical Damage
Pruning tools need to be disinfected with alcohol, and wounds should be treated with wood ash. After major trauma, water management should be controlled, and normal management can resume after the callus tissue forms.
Precise Fertilization Guidelines
Use a balanced 20-20-20 fertilizer in spring and autumn, and switch to a high-phosphorus 10-30-20 fertilizer during the flowering period. Soil application combined with foliar spraying of chelated iron fertilizer can improve yellowing.
Environmental Control Tips
In winter, use double-layer insulation: inner layer of plastic film (with ventilation holes), and outer layer wrapped in non-woven fabric. In summer, sprinkle water on the ground to cool down and use ceiling fans to enhance air circulation.
By implementing the above systematic maintenance measures and regularly observing the leaf condition, the yellowing issue in chives peony can be fundamentally improved. It is recommended to conduct a comprehensive health check every quarter: inspect the roots, measure the soil, and observe the leaf color, adjusting the maintenance plan in a timely manner to keep your chives peony shining like jade all year round.
