【Reasons and Solutions for Yellowing of Peony Leaves】
<1. Soil Imbalance Causes Yellowing>
When peonies grow in alkaline soil for a long time, leaves turn from green to yellow. As the degree of yellowing intensifies, it leads to white leaves, crispy edges, leaf drop, and in severe cases, the top of the branches withers, eventually killing the plant.
The best solution to this phenomenon is to spray the leaves with a 0.2% to 0.3% ferrous sulfate solution 3-5 times. Note that the concentration should not be too high and should be mixed and used immediately.
<2. Incorrect Watering Causes Yellowing>
Too much watering can cause waterlogging in the potting soil, leading to leaf yellowing due to prolonged moisture. Insufficient watering, resulting in a lack of water supply, can also cause leaf yellowing.
Watering peonies should be moderate and based on actual conditions. If the pot is small, it should be watered frequently. If the pot is large, water when the topsoil becomes dry. If watering is insufficient, water promptly. Water thoroughly but avoid waterlogging.
<3. Improper Fertilization Causes Yellowing>
Insufficient fertilization or low fertilizer concentration can cause young leaves and tender stems to turn yellow slowly. Excessive fertilization or high concentration can cause fertilizer damage and leaf yellowing.
If fertilization is insufficient, add fertilizer promptly and moderately. Avoid excessive fertilization. If fertilization is excessive, water promptly, and in severe cases, repot the peony and change the soil.
<4. Root Rot Causes Yellowing>

Peony has a fleshy root. Improper potting soil, failure to repot in time, and bacterial infection can cause root rot. Initially, it's hard to notice any abnormality in the above-ground part, but the absorption capacity of the roots gradually weakens, and the lower leaves turn yellow, eventually spreading to the entire plant.
Every year when repotting, check the root growth condition and prune the roots promptly. Maintain soil permeability and ensure proper drainage. Be careful with the amount of watering to avoid waterlogging that causes root rot.
<5. Diseases and Pests Cause Yellowing>
Peonies are often affected by underground pests such as grubs, mole crickets, and nematodes, causing the leaves to lose green and turn a soil-like yellow, or even become crispy. The main characteristic of this symptom is that individual or several plants in a certain area have yellowing and crispy leaves.
For diseases, spray with Bordeaux mixture 1-2 times a month, or 3 times if the condition is severe. For pests, spray with a 40% omethoate emulsion diluted in 1500 times water for good results.
