The 6 Major Reasons for the Withering and Yellowing of Peony Leaves
Today's lifestyle tip brings you the 6 major reasons for the withering and yellowing of peony leaves, as well as some green plant maintenance tips. Let's dive into the introduction by the editor.
During the cultivation process, peony flowers often show symptoms of withered and yellowing leaves. Why does this happen? And how should we deal with it? Let's introduce the reasons and countermeasures for the yellowing of peony leaves.
The 6 Major Reasons for the Withering and Yellowing of Peony Leaves
1. Overwatering
Peony flowers prefer dry conditions and dislike moisture, especially积水. If the potting soil remains too wet for an extended period, it can cause poor root respiration and result in yellow leaves.
The main manifestation of overwatering-induced yellowing is that old leaves show no significant changes, while new leaves turn yellow. If you notice that the new leaves of peonies are yellowing and the potting soil is relatively moist, consider it as a sign of overwatering.
Countermeasures: Loosen the soil promptly, enhance ventilation, control watering, and prevent积水 in the potting soil.
2. Yellowing Due to Drought
Although peonies prefer dry conditions, excessive drought can also cause yellowing. Drought-induced yellowing typically shows yellowing from the bottom up, with old leaves turning yellow first, while new leaves remain normal.
Countermeasures: Water the peony pots promptly when the soil is too dry to supplement moisture.
3. Soil Overly Alkaline
We've mentioned before that peonies cannot grow in overly alkaline soil, so rice chaff ash is used instead of wood ash when preparing the soil, as wood ash is too alkaline.
If the potting soil is too alkaline, peony flowers will not grow well and show yellowing leaves. This is mainly manifested by the loss of green between the veins, while the main veins remain green, showing a yellow-green pattern. In severe cases, the veins gradually lose their green, the entire leaf turns white, and the leaf edges become crispy and fall off.
Countermeasures: When the potting soil is too alkaline, apply acidic fertilizer promptly to neutralize the soil's alkalinity.

4. Improper Fertilization
Peonies require careful fertilization. Liquid fertilizers are generally not used, and raw or concentrated fertilizers should not be used either. Improper fertilization can cause yellowing leaves and dried leaf tips in peonies. Sometimes, it may also show symptoms of thick, shiny, and uneven new leaves.
Countermeasures: If yellowing leaves or dried leaf tips appear after fertilization, it indicates fertilizer damage. Use a large amount of water to flush the roots to dilute the concentration of inorganic salts in the soil.
If new leaves are thick and uneven, stop fertilizing for a period and allow them to recover naturally.
5. Malnutrition
Many people, upon hearing "clear peonies," are afraid to fertilize, leading to malnutrition due to insufficient fertilizer, which manifests as yellow leaves. Malnutrition first appears in new leaves.
Countermeasures: When yellowing is caused by insufficient fertilizer, apply additional fertilizer promptly. You can use fermented organic fertilizer for shallow application or apply a low-concentration water-soluble fertilizer on the leaf surface.
6. Root Rot
The above five types of yellowing are relatively easy to solve, but yellowing due to root rot can be more complicated.
Root rot in peonies may be caused by积水 in the potting soil or by root rot disease. In any case, root rot leads to yellowing and falling of leaves from the bottom up, gradually spreading upwards.
Countermeasures: For minor root rot, use fungicides like carbendazim or mancozeb to flush the roots and control water.
If the root rot is severe, dig up the peony, trim the rotten roots, soak in a mancozeb solution, and then replant with new soil.
