The richness and beauty of peony are admired by the world. Many people like to cultivate peonies at home during the Spring Festival, which can make the indoor life vigorous. How to cultivate the indoor potted peonies? How long does the peony water better?
How to raise Peony
The richness and beauty of peony are admired by the world. I still remember that when I was a child, my neighbor planted several pots of Peony Seedlings. Because I didn't know the growth habits of peony, I put all the peonies outside the yard in the winter, and all the peonies died. As a spectator, it was full of sadness. As a child, peony is a very precious species, which is more difficult to raise than rose and Narcissus. After growing up, the network is more convenient in all aspects, so we have a deeper understanding of the cultivation methods of peony flowers, and then we can understand why the peony flowers of the neighbors died: caused by low temperature. Here, a brief introduction of qijiawang tells you the main points of cultivating peony: the characteristics of peony are "four should be four afraid", that is to say, it is better to be cold and cold, warm and hot, light and shade, and dry and wet.
The most suitable season for planting peony: potted cultivation of peony is recommended in September October. Family culture should pay special attention to the selection of varieties. Compared with other varieties, Luoyang red, Hu Hong and other varieties of peony are more suitable for pot culture, and they have stronger adaptability to the environment. Peony should be used as the rootstock of 3-4-year-old tree peony or the branch seedlings with 3-5 branches. Peony can also be propagated by sowing, but it will take 4-5 years to bloom by sowing and breeding.
Flowering period of peony: April to May is the flowering period of peony. If properly managed, the normal flowering period is generally about 10 to 15 days. Of course, there are also relatively long flowering periods, about 20 days. The flowering period of peony will be affected by the climate and temperature. When the peony blooms, it can be covered by shed or temporarily placed indoors to avoid direct sunlight, which can prolong the flowering period. If the top bud of the main branch is a leaf bud, it should be removed to avoid excessive growth and affect the flowering. In order to make the peony bloom brightly, 0.5% - 1% dihydrogen phosphate solution can be sprayed on the leaves for 2-3 times.
How to manage the peony flower after flowering: pick flowers and cut branches in time after flowering, cut according to the natural growth of the tree shape and the tree shape you want, and at the same time, apply the anti-corrosion film of callus on the trimming mouth to protect the wound and prevent the invasion and infection of pathogens. If you want to plant low and dense flowers, you should cut them short to prevent branch expansion and root tillering. Generally, it is better to keep 5-6 branches per plant.
The main reasons for the low survival rate of potted peony are: 1. Improper temperature control. 2. Improper fertilization. 3. Light conditions.
Growth habit of peony
1. Pay special attention to temperature, watering, light, fertilization and other factors when cultivating peony in South China. Peony is a deep-rooted deciduous shrub and flower, which likes sunshine and cold weather. It loves cool environment and avoids high temperature and sultry. It is suitable for the growth of loose, fertile and well drained sandy soil (it is better to choose the mixed soil of sand and cake fertilizer, or the culture soil mixed with fully decomposed manure, garden soil and coarse sand in the proportion of 1:1:1). Peony is suitable for ground planting because of its long root and large plant. If it is to be potted, it is necessary to select a large, well permeable tile basin with a depth of more than 30cm. It is better to use a tile cylinder with a depth of 60-70 cm. It's hot and dry in South China. When it's hot in summer, it's necessary to prevent Peony from being exposed to the sun and take cooling measures in time. Some of the peonies planted in Huayou reaction do not bloom here is a reminder that if the temperature is not well controlled, it will be heated and fallen leaves, which will seriously affect later flowering.
2. The root rot of peony is often caused by improper watering. Generally, the potted soil for cultivating peony should be as moist as the cultivated soil, and its fleshy roots are easy to rot. In case of continuous rain, drainage shall be carried out in time, and the root shall not be allowed to accumulate water. The potted plants should be moved indoors in continuous rain. In summer, there is basically no watering. In spring and autumn, the temperature rises. Generally, watering takes about 10 days. If it can't be poured to the bottom of the basin at one time, it can be poured several times until the bottom exudes water. Later watering depends on the dryness and wetness of the basin. In summer, pay attention to watering, do not make pot soil too dry and affect plant growth, pot soil can keep moist is appropriate. Do not fertilize the peony in the new basin. After half a year, fertilize the peony gradually. Do not apply fertilizer too often, 2-3 times a year. In the first ten days of March, when the buds and leaves are extended, in order to increase and increase the flowers, fertilization can be applied once; in the last ten days of May, when the flowers just withered, fertilization can be applied once to supplement nutrients. The best fertilizer is fermented chicken manure water or bean cake water, and the proportion of fertilizer and water is 30%. Fertilization should be carried out in sunny days when the basin soil is dry. Stop watering before construction. At the same time, be careful not to splash the fertilizer solution on the branches and leaves. If it has been stained, rinse it with clear water.
3. Improper fertilization will cause the leaves of peony to turn yellow. More or less fertilizer will cause the leaves to turn yellow. Do not fertilize the peony in the new basin. After half a year, fertilize the peony gradually. During the growing period, the soil should be loosened frequently, and fertilization should not be too frequent, only 2-3 times a year. In the first ten days of March, when the buds and leaves are extended, in order to increase and increase the flowers, fertilization can be applied once; in the last ten days of May, when the flowers just withered, fertilization can be applied once to supplement nutrients. The best fertilizer is fermented chicken manure water or bean cake water, and the proportion of fertilizer and water is 30%. Fertilization should be carried out in sunny days when the basin soil is dry. Stop watering before construction. At the same time, be careful not to splash the fertilizer solution on the branches and leaves. If it has been stained, rinse it with clear water.
4. If you don't pay attention to the light, the peony will lose its leaves. After the potted peony plant is transferred to normal management, it can be placed in the sunny place to ensure that it has sufficient sunlight. Peony is a long sunshine plant that likes light and bears half shade. The natural light hours of flowering process are about 10-12 hours. Therefore, if the flowers are urged in the greenhouse, the light hours should be extended as much as possible to more than 10 hours. Especially in the early and middle stages, if the light duration is less than 8 hours, the flower bud will stop developing and gradually shrink, even the leaves will stop growing, among which Hu Hong is particularly sensitive. The lack of light hours is an important reason for the failure of peony flower induction.
5. The cultivation of peony in the North needs to be noted: Although the peony is relatively cold resistant, it should be moved into the room before and after the beginning of winter in cold areas such as North China, and placed in the sunny part of the room. The room temperature should be kept at about 0 ℃. It's not advisable to leave the room early the next year. You should wait for Qingming to leave again. In the area not too cold, the flowerpot can be buried in the soil at the place with hidden wind, so that the basin surface is flush with the ground, so as to maintain the humidity and temperature of the basin soil, and also ensure the peony to survive the winter safely. In the spring of the next year, the peony will be dug out from the ground and managed normally.
6. Prevention and control of peony flower diseases and insect pests: the common diseases of peony are brown spot, root rot and scale insect. In case of brown or black spots on the leaf surface, Bordeaux solution can be used for spraying 1-2 times a month, or 3 times if the disease is serious. Cut and burn off the leaves with serious diseases to prevent spreading. If root rot is found, cut off the root and burn it, and sprinkle some sulfur powder in the planting hole during planting. The scale insects were sprayed with 40% Omethoate emulsion and 1500 times aqueous solution.
