How to save peony flowers from yellowing leaves

Reduce watering

If you water too frequently or too much, the young leaves will turn yellow, but there will be no obvious changes on the old leaves. If you water too little, the plant will lack water and the old leaves will start to turn yellow from the bottom to the top. If the water shortage lasts for a long time, the leaves of the whole plant will turn dark yellow or even die.

Solution: Water at the right time and in the right amount according to the condition of the potting soil. For smaller flowerpots, water them frequently, and for larger flowerpots, water them after the soil surface becomes dry. It is best to water thoroughly, and do not allow water to accumulate in the soil.

Reasonable fertilization

If too much fertilizer is applied or fertilization is applied too frequently, the leaf surface will grow well, the leaves will be thick and shiny, but the leaves will become uneven over time, and root rot may occur in severe cases. When the peony lacks nutrients or no fertilizer is applied for a long time, the young leaves and tender stems will turn yellow, gradually causing the whole plant to turn yellow or even die.

Solution: Apply too much fertilizer and water in time. In serious cases, remove the plant from the pot and replace the soil. When there is a lack of fertilizer, do not apply concentrated fertilizer all at once, but supplement nutrients gradually.

Prune rotten roots

Peonies have fleshy roots. If the potting soil is not suitable or the pot is not changed in time, bacterial infection will cause root rot. In the early stage, it is difficult to find any abnormalities in the above-ground part, but the absorption capacity of the roots gradually weakens, the lower leaves will slowly turn yellow, and gradually spread to the whole plant.

Solution: Repot every year, check the root growth, and prune the roots in time. Be careful when watering to avoid waterlogging and root rot.

Preventing pests and diseases

Peonies are often harmed by underground pests and nematodes such as white grubs and mole crickets, causing the leaves to lose their green color and turn earthy yellow, or even become dry and scorched. The main symptom of this condition is that the leaves of a single or several plants in a certain place turn yellow and burnt.

Solution: When symptoms appear, use pesticides to irrigate the roots promptly, or remove the plant from the pot, disinfect it, and replace it with new soil.
