Characteristics of peony leaves, photosynthesis of peony leaves, drought tolerance of peony, growth environment of peony, pruning management of peony, nutritional needs of peony, Peony, known as the "king of flowers", has been deeply loved by people since ancient times, whenever spring comes, when peony is in full bloom, the gorgeous flowers can always attract the attention of countless tourists. Have you ever wondered why the peony leaves are still green in spring and summer without turning yellow? Let us reveal the secret that peony leaves do not change yellow. Characteristics of peony leaves Peony belongs to the peony family. It is a perennial deciduous shrub. Its leaves are pinnately compound leaves, usually green, with obvious veins. The reason why peony leaves are not easy to turn yellow is related to their own physiological characteristics. Photosynthesis of peony leaves Peony leaves contain a large amount of chlorophyll, which is a key substance for photosynthesis. Photosynthesis is the basis of plant growth. Through photosynthesis, plants can absorb energy from sunlight and convert carbon dioxide and water into organic matter. At the same time, oxygen is released. The chlorophyll content in peony leaves is high, so the leaves can remain green even in the case of insufficient light. Drought tolerance of peony Peony has strong drought tolerance. Even in arid environments, its leaves can remain green. This is because the surface of peony leaves has a layer of wax, which can reduce the evaporation of water and thereby maintain the moisture balance of the leaves. The growth environment of peony Peony is suitable for growing in an environment with sufficient sunshine and good drainage. In such an environment, the leaves of peony can receive sufficient sunlight, thereby promoting the synthesis of chlorophyll and keeping the leaves green. Pruning management of peonies The pruning management of peonies is also an important factor in keeping the leaves green. During the growth period, timely pruning of weak and dense branches and leaves can promote the growth of peonies, reduce the occurrence of pests and diseases, and also benefit the sun and air circulation keeps the leaves green. Nutritional needs of peonies Peonies have high nutritional needs, especially during the period of vigorous growth. Reasonable fertilization can provide the nutrients needed for peonies to grow and make the leaves greener. Regular spraying of foliar fertilizer can also replenish the leaves needed. Various trace elements enhance their disease resistance.
The reason why peony leaves are not easy to turn yellow is related to many factors such as their own physiological characteristics, growth environment, pruning management and nutritional needs. Understanding these factors will help us better maintain peonies and keep them in spring and summer. Keep the green leaves and add a beauty to our lives.
