What Causes the Yellowing of Peony Leaves
Do you know these? Let's find out together about the content related to green plants and flowers, such as why peony leaves turn yellow.
What Causes the Yellowing of Peony Leaves
Peony leaves turn yellow due to insufficient fertilization, excessive sunlight, and unsuitable soil. First, water the plant with a dilute liquid fertilizer and spray a small amount of foliar fertilizer. In summer, use a shading net to adjust the light intensity of the care environment, ensuring that the light is sufficient but not too strong to burn the plant. For unsuitable soil, prepare fertile and loose acidic potting soil and replant the plant.
Reasons for the Yellowing of Peony Leaves
1. Forgetting to Fertilize: Peonies are plants that like fertilizer. During their growing season and bud formation period, they need to be fertilized. If fertilizer is not applied for a long time, the plant may grow poorly, which can cause yellowing of the leaves.
2. Sunburn: Peonies need sunlight for growth and flowering, but if they are exposed to strong sunlight, their leaves may become sunburned and turn yellow, which is harmful to their growth.
3. Unsuitable Soil: Peonies prefer acidic potting soil and do not like to grow in alkaline soil. If the soil pH is too high, the plant may turn yellow due to its inability to adapt to the soil conditions.
Methods to Treat Yellowing Peony Leaves
1. Fertilization: If peonies are not getting enough fertilizer, first water the plant with a dilute liquid fertilizer and spray a small amount of foliar fertilizer. Then, increase the frequency of fertilization to provide nutrients and help it recover.
2. Sunlight: Peonies easily develop yellow leaves under strong sunlight. Cut off the already yellowed leaves and use a shading net to adjust the light intensity of the care environment, ensuring that the light is sufficient but not too strong to burn the plant.
3. Repotting: If the soil is unsuitable for peonies, remove the plant from the pot, wash the roots, and then place them in a well-ventilated area to dry. After that, prepare some fertile and loose acidic potting soil and plant it in it for maintenance.
Prevention and Control of Yellowing Peony Leaves
Peonies prefer a sunny environment where they can accumulate nutrients. However, strong sunlight and direct sunlight during the noon can burn peonies. To avoid direct strong sunlight and excessive water loss, it is best to keep them indoors with a temperature controlled around 25 degrees Celsius and ensure proper ventilation.
