Cultivation method of Sedum sarmentosum
Many people don't know much about Sedum sarmentosum. In fact, Sedum sarmentosum is a kind of herb with delicate leaves and green color, which is very popular. But some people don't know how to cultivate Sedum sarmentosum. The following is the cultivation method of Sedum sarmentosum!
Sedum sarmentosum 1 culture method, culture soil
In the cultivation method of Sedum sarmentosum, ensuring suitable soil is the key. Sedum sarmentosum doesn't require much soil, but the soil must be breathable and nutritious. It is suggested that mixing humus soil, pastoral soil, river sand soil and a small amount of organic fertilizer can meet the needs of plant growth.
2, warm measures
Sedum sarmentosum likes warm environment, the most suitable temperature for growth is about 20℃, and its cold tolerance is poor. Therefore, the cultivation of Sedum sarmentosum in winter needs to take corresponding warm-keeping measures. It is suggested that when the temperature drops to 10℃, plants should be moved indoors to keep warm, and the ambient temperature should be controlled above 5℃, so that plants can safely overwinter.
3. Shading measures
Sedum sarmentosum likes semi-shady environment, and the demand for light for plant growth is not high. Under normal circumstances, normal light can be given in spring and autumn; In summer, corresponding shading measures must be taken to avoid the damage of strong light to plants; The cultivation of Sedum sarmentosum in winter needs to strengthen the light, which is beneficial to the overwintering of plants.
4. Suitable fertilizer and water
The maintenance of Sedum sarmentosum must be properly watered and fertilized. Sedum sarmentosum has a high demand for water, and the soil must be kept moist in spring, summer and autumn. In winter, plants can be watered less and the soil can be kept dry.
In addition, in the growing season of Sedum sarmentosum, dilute liquid fertilizer should be applied every half month to meet the needs of plant growth.
Cultivation method of Sedum sarmentosum 2 Sedum sarmentosum is extremely barren, and the general soil can adapt, and the sand with good drainage is the most suitable. You can sow and reproduce by yourself. See sunshine blossom, cloudy day in the morning and evening, so it has the name of Sedum sarmentosum and afternoon flower.
To propagate by sowing or cutting. Sowing can be done in spring, summer and autumn. When the temperature is above 20℃, the seeds germinate and germinate about 10 day after sowing. Cover the soil thinly, and you can grow without it.
Seedlings are planted separately, and the row spacing is 5×6 cm. Liquid fertilizer needs to be applied several times. The temperature is above 65438 05℃, and it blooms in about 20 days. Cutting propagation is usually used for double-petal varieties. In summer, cut branches are used as cuttings, wilting stems can also be used, and buds appear after living cuttings.
Transplanted plants don't need soil, and they don't need to be watered often during the growing period. When the fruit is ripe, it cracks and the seeds are easy to scatter, so it needs to be harvested in time.
Sedum sarmentosum is generally based on seed propagation and has strong self-sowing ability. However, with the emergence of a large number of new horticultural varieties, it is difficult to collect their seeds. Especially the new horticultural varieties with double petals do not bear seeds after flowering. Therefore, cutting can be used for family reproduction.
1. Overwintering of seedlings: After the first frost and solar term (Shanghai area) every year, move Sedum bicolor to indoor sunlight. Put it on the inside of the glass window after winter, so that the soil in the basin is a little dry, and it can be safely wintered. After Tomb-Sweeping Day in the following year, the flowerpot can be placed outside the window, and it needs to be maintained in the window in case of cold current.
2. Cutting time: from the beginning of May to the end of August, you can cut off the top of the tender stem of about 5cm for cutting.
3. Preparation of culture soil: It can be prepared by mixing 3 parts of garden cooked soil, 5 parts of yellow sand, 2 parts of chaff ash or fine sawdust evenly and adding a little calcium superphosphate powder.
4. Planting containers: pottery pots, porcelain pots, plastic flower pots or other containers with water seepage at the bottom. Put tiles on the bottom of the seepage to facilitate seepage, and then plant them in the culture soil.
5. Cutting method: planing the culture soil in the container, and inserting the cut Sedum sarmentosum twigs into the holes poked by bamboo chopsticks, with the depth of the culture soil not exceeding 2 cm at most.
In order to make the potted flowers shape and plump as soon as possible, one pot can see the size of one pot. As long as the spacing of 2 cm can be maintained, multiple plants can be cut (other pots can be planted when there are many seedlings).
Then pour in enough water. New cuttings can be shaded or not. As long as they keep a certain humidity, they can survive in 10 ~ 15 days and enter normal maintenance.
6, usual maintenance: Sedum sarmentosum has very few pests and diseases. Maintaining a certain humidity at ordinary times and applying one thousandth of potassium dihydrogen phosphate once every half month can achieve the purpose of large flowers, bright colors and continuous flowers. If multiple varieties are cut in a pot and all kinds of flowers are opened in a pot, the appreciation value is higher.
Matters needing attention in Sedum sarmentosum cultivation:
1, Sedum sarmentosum can resist drought and high temperature: Sedum sarmentosum can adjust its moisture when it is dry; Strong water absorption capacity, and it will not dry up without watering for a month (including natural precipitation); Sedum sarmentosum is extremely resistant to high temperature: it can still grow vigorously at a high temperature of about 45℃.
2. Sedum sarmentosum has strong cold resistance: when the lowest temperature in Shenyang reaches -32℃, it can safely overwinter without freezing injury.
3. Sedum sarmentosum is resistant to moisture, salt and barren: it can grow in the crevices of hillside rocks all year round.
4. Sedum sarmentosum has a long green period and high ornamental value: the ornamental period of Shenyang green leaves is as long as 8-9 months, which generally turns green at the end of March and withers in 65438+early February. Beautiful grass, green as jade, quite neat and spectacular; Golden and bright color, high ornamental value.
5. Sedum sarmentosum has strong resistance to pests and diseases: it has been used in Shenyang for many years and basically has no pests and diseases.
6, Sedum sarmentosum grows fast, easy to reproduce, and does not need pruning.
Will Sedum sarmentosum freeze to death in winter?
1, it will freeze to death.
Sedum sarmentosum will freeze to death in winter, because Sedum sarmentosum is suitable for growing in a warm environment, so it is necessary to take warm measures for Sedum sarmentosum in winter.
Sedum sarmentosum can be covered with straw mat or plastic film, or moved to a warm room for maintenance, and the ambient temperature should be controlled between 15-25 degrees.
Step 2 stop watering
Sedum sarmentosum will go into dormancy in winter and can't absorb water. At this time, if you water, it will lead to water accumulation in the soil.
Therefore, Sedum sarmentosum died, so we should stop watering to keep the soil dry, and stop fertilization to avoid the damage of fertilizer to Sedum sarmentosum, and then maintain Sedum sarmentosum after the temperature rises.
Step 3 trim regularly
Sedum sarmentosum needs pruning when it is maintained in winter. Branches of Sedum sarmentosum that grow too long can be cut off to avoid leaving too much nutrients. It is also necessary to move Sedum sarmentosum to a bright place indoors and receive sufficient natural light, so that Sedum sarmentosum can receive sufficient natural light and help Sedum sarmentosum survive the winter smoothly.
4. Maintenance management
Sedum sarmentosum needs normal maintenance and management after overwintering, and balanced nitrogen, phosphorus and potassium fertilizer can be applied every other month.
In order to promote the vigorous growth of Sedum, it is also possible to water Sedum once every other week to keep the soil moist, provide the water needed for Sedum growth and make its leaves greener.
