When is the best season to plant peony?

Peony is also known as Mu Peony, Luoyang Flower, Fortune Flower, Ancient Jade Flower, Kaohua, Gome, Tianxiang and so on. Paeonia lactiflora is a deciduous shrub of Ranunculaceae. Generally, the stem height is 1-2 meters, and the height can reach more than 3 meters. Roots are strong and fleshy. Many branches are overgrown. The leaves are broad, with two ternary pinnate compound leaves, long petioles and 3-5 lobes at the top. Flowers are solitary at the top of annual branches, with a diameter of 15-30 cm. Rich in design and color, there are many colors such as crimson, pink, yellow, white, green, purple, deep purple and blue. Flowers are single or double. The flowering period is April-May. Peony is one of the top ten famous flowers in China. Its flowers are big and bright, with different shapes and colors, good color and fragrance. Therefore, it has the reputation of "national beauty and fragrance" and "king of flowers". In the garden, it is suitable for single plant, cluster planting or patch planting.

Peony can be propagated by sowing, branching, grafting and layering, but the branching method is relatively simple. Peony is a bush, which is very suitable for branching. It is more suitable for autumn to divide plants from late September to1mid-October. During this period, the root wounds of planted peony are easy to heal, and some new roots can grow rapidly. It is too late to divide plants, and the root injury is difficult to heal, so the new roots can not germinate in that year. After germination in early spring of the following year, it needs a lot of water and nutrients to grow and blossom. Insufficient supply of water and fertilizer caused plants to wither and die.

However, it is not advisable to divide plants too early, because the temperature is still very high at this time, which is easy to cause terminal bud germination (commonly known as autumn hair), consume nutrients, and also affect the growth and flowering of the next year. If plants branch in spring and the weather gets warmer, peony will germinate quickly and need a lot of water and nutrients. But at this time, the root system has not healed, which will also cause nutritional imbalance. Not only can it not bloom in the same year, but its growth potential is weak, which affects the next year's flowering. , so it is generally not needed.

When dividing plants, healthy four-or five-year-old plants should be selected as mother plants, the whole plant should be dug out of the soil, the soil attached to the roots should be gently shaken off, and dried in the shade for 2-3 days until the roots are slightly softened. According to their connection mode, they are separated by hand or with a sharp knife to form several hard blocks. Each cluster has 3-4 branches and 2-3 roots. Apply charcoal powder to the wound as a preservative, and then continue. Planting. The planting depth is the same as the original planting depth of the seedlings. Not too deep and not too shallow. The depth is too deep, the plants grow badly, the leaves turn yellow, and the roots are easy to rot; Water and shade after planting. In the cold winter area in the north, peony should take some cold-proof measures after planting in the open field, such as burying soil or wrapping grass at the root neck.

Through our introduction, I believe everyone has a deeper understanding of when to plant peony in the best season and when to plant peony in autumn.
