How to cultivate the latest peonies?

Peony is one of the main varieties of cactus ball plants, also known as red lantern, red peony, etc., is a variety of cactus naked calyx bulb Ruiyun variety peony variety, origin in South America, the color of the sphere remains the same all the year round, placed on the balcony in winter with few flowers with a little red decoration effect, let's take a look at how to cultivate peony!

Growth habits of Paeonia suffruticosa

The peony likes the sunny and warm environment, the more the sphere is exposed, the brighter the color is, while the plant growing in the shade is dark and without luster, but in the hot summer, it still needs proper shade to avoid strong sunlight to burn the sphere, and strengthen ventilation, and spray water to the plant when the air is dry, in order to prevent the harm of red spiders caused by high temperature drying and poor ventilation. During the growing period, the mature thin liquid fertilizer was applied every 10 to 15 days, and the rootstock was dried and thoroughly watered to avoid rootstock rot caused by long-term stagnant water in the basin soil, and proper air humidity was given to make the sphere color fresh and moist. In winter, keep it in an indoor place with sufficient light, stop fertilization, control watering, and maintain a room temperature above 8 ℃.

Propagation methods of Paeonia suffruticosa

Due to the lack of chlorophyll in the sphere itself, peony can not carry out photosynthesis and produce nutrients. It must be grafted and rely on rootstocks to provide nutrition in order to grow normally. Cactus plants with strong habits, such as rootstock, thick flake cactus and leaf cactus, can be carried out in the greenhouse all year round, but the success rate is the highest in late spring and early summer. The grafting method is generally flat grafting, but when the leaf cactus is used as the rootstock, the embedding method is used. The propagation of peony crown can cut the flattened fan-shaped plant into small pieces and make each piece with some growth cones, and then grafted. The propagation of dragon and Phoenix peony can be grafted with twisted abnormal stems, but can not be grafted alone with the red balls above, and then can only grow into globular peonies, but can not grow into twisted variegated abnormal stems of swimming dragons.

How to raise peonies?

1. Soil: peat, peat and magnolia soil should be mixed with a small amount of perlite, the acidity and alkalinity should be slightly acidic to neutral, and the pH should be 6.0-6.5. When going up the basin, the bottom of the basin should not put the tile of the basin, but should put a small amount of ceramsite.

2. Temperature: the optimum temperature for the growth of Paeonia suffruticosa is 2: 15 ℃, and it can withstand high temperature of 40 ℃ and low temperature of 2 ℃ under the condition of basin soil drying.

3. Humidity: the requirement of peony is 60-75%. If the indoor temperature is low in winter, it should be kept relatively dry.

4. Light: there should be sufficient light in the process of peony culture except in the middle of summer.

5. Moisture: in the process of peony culture, the peony should be watered at the right time except in winter, usually mastering medium moisture or drier.

6. Diseases and insect pests: stem rot and gray mold often occur in tree peony, which can be sprayed with 2500 times of carbendazim wettable powder. The red spider is seriously harmful when it is hot, humid and poorly ventilated. It is sprayed with 1000 times of 40% dimethoate EC.

Four Seasons Management of Fengmu Peony

1. Spring: change the basin once a year when the temperature is stable at 10 ℃ in spring. Change the basin to survive and move to a place with sufficient light for culture. if the light is insufficient, the lower part of the sphere will turn green and become redder and redder under direct light. Spring is the peak growing season, so we should pay attention to the supply of water, but the soil should not be too wet, and it is appropriate to water the soil after it is dry. Rain Water should reduce the frequency of watering in more weather.

2. Summer: when the summer temperature is hot, it should be cultivated in a place with morning and evening light to maintain an adequate water supply, but watering should be dry and wet, and pay attention to spray around it several times a day and strengthen ventilation to cool down. After the temperature is cool at the end of summer, it should be moved to a place with plenty of light for cultivation.

3. Autumn: in autumn, peonies should be cultivated in a place with sufficient light but no rain, and it is better to see the soil dry for water. After the weather is getting cooler, the amount of water can be gradually reduced, making the basin soil dry until dormancy. When the outdoor temperature drops to the right of 10 ℃, it should be moved into a closed balcony or room with light.

4. In winter, tree peony is not resistant to cold. The indoor temperature should be kept above 8 ℃ in winter, and it is best to keep it at about 0 ℃. Potted plants should be placed on the windowsill or balcony with sufficient light to cultivate, pay attention to water control, so that the basin soil is dry, the lower the temperature, the drier the basin soil should be.
