What are the breeding methods and matters needing attention of Yushu (Sedum crassulata)? What's the difference between a swallow's palm and a swallow's palm?

Yushu, also known as crassulaceae, is a succulent subshrub of the genus Sedum. The leaves are peculiar in shape, such as Jasper, summer and autumn, flowers are in full bloom, green and white, they are excellent plants for potted plants. The following editor introduces you to the breeding methods and matters needing attention of Yushu:

1. Selection of flowerpots for Yushu culture

(1) flowerpot requirements: muddy flowerpots, plastic pots, porcelain pots and pottery pots can be used. In order to coordinate with home decoration, it can be cultivated in porcelain pots.

(2) flowerpot size: Yushu is generally planted in pots with a diameter of 16cm to 28cm.

two。 Soil selection of Yushu Culture

Yushu is not cold-resistant and requires a dry and well-ventilated environment. The requirement of soil is not strict, and the sandy soil with loose and good drainage is suitable. The basin soil was prepared with 5 parts of rotten leaf soil, 2 parts of garden soil and 3 parts of river sand. Extremely resistant to drought and avoid excessive moisture in the soil. Yushu likes dry air and dry soil, avoid moist soil, basin soil moist easy to cause root rot.

3. Watering method of Yushu Culture

Keep the basin soil moderately moist during the growth period. If the drainage of the basin soil is not smooth, and the watering is too much, the roots will rot because of stagnant water. On the other hand, the basin soil is too dry, the weather is muggy, and the air is not circulating, which can easily cause fallen leaves. The amount of water should be controlled according to temperature, watering in summer can be more appropriate, at the same time, attention should be paid to indoor ventilation and cooling to promote growth; watering should be controlled in winter, usually once every 7 to 10 days.

When the temperature is low in late autumn, winter and early spring, it is in a semi-dormant state. Watering should be strictly controlled to make the basin soil dry and not dry. When the temperature rises in spring, it begins to grow, and the amount of water can be gradually increased to keep the soil dry. Watering should be done after the basin soil is dry. After the temperature gets cooler in autumn, the watering is gradually reduced, and finally the basin soil dries to the dry state.

4. Fertilization methods for Yushu Culture

Yushu grows faster, in order to keep the plant shape plump, fertilization can not be too much, indoor fertilization can not be applied. Nitrogen-based fertilizer should be applied for 2 to 3 times in the whole year, and the fertilization concentration should not be high, so it should be carried out in the vigorous growth season.

The young plants change their pots every spring, after the end of the dormant period.

Yushu likes fertilizer, but it doesn't require much fertilizer. Topdressing began after the new stem grew in spring, and 15 times of rotten liquid fertilizer mixed with 1000 times of potassium dihydrogen phosphate or 1000 times of "Huaduoduo" general fertilizer could be applied once a month in the growing season. No fertilization is applied when the summer temperature is high and the winter temperature is low.

When the plant shape of Yushu is larger, only base fertilizer is applied, and no topdressing is needed to control the height. Base fertilizer can be used mature soybean cake fertilizer, soybean milk dregs and other organic fertilizer. The application rate of base fertilizer is 10% of that of basin soil. Mix the base fertilizer with the soil and transplant it in a pot.

5. Temperature and light requirements of Yushu culture

Yushu is more shady, family care can be placed all the year round in a place where there is no direct light, or where there is bright scattered light. The room temperature is kept at 6: 10 ℃. Too high temperature is easy to cause overgrowth, leaf shedding or diseases and insect pests. Low temperature in winter can promote flower bud differentiation, and plants go into dormancy when the temperature is below 5 ℃.

6. Four Seasons Management method of Yushu Culture

(1) Spring management

The seedlings grow fast, the pots are changed once a year, and the formed plants are changed once every 2 to 3 years. The time of basin change takes place when the temperature is stable above 10 ℃ in spring. Stop watering for several days before changing the basin to dry the soil and remove the basin. As its branches and leaves are rich in water and easy to break, they should be handled gently to avoid breaking plants. After taking off the basin, cut off the dead roots and cut the roots, dry them for 1 or 2 days and plant them. After planting, put it in a semi-shady place, do not water temporarily, water slightly after 2-3 days, and keep the basin soil partial.

The cultivation and management of Yushu is simple, and it is the key to control soil moisture and ensure sufficient light. Yushu has a good sunny and ventilated environment, so it is not suitable to be cultivated together with other plants that like moist air.

(2) Summer management

Yushu likes strong light, does not need shade when the summer temperature is not high, and maintains a proper water supply. When arranged indoors, you should maintain a certain amount of light and pay attention to indoor ventilation. The growth is stagnant when the summer temperature is higher (more than 35 ℃). Attention should be paid to water control to prevent too much high temperature water from rotting roots, cover up the light around noon and stop fertilization. Fertilization can be continued after the temperature is cool at the end of summer.

(3) Autumn management

It should be cultivated in a place with plenty of light in autumn. After the basin soil is dry and watered, the amount of water can be gradually reduced when the weather is getting cooler, stop fertilization, and make the basin soil dry and not dry. When the temperature drops to about 5 ℃, people should be moved to the closed balcony with light or cultivated in the room.

(4) Winter management

Yushu is not cold-resistant, and the indoor temperature should be kept above 5 ℃ in winter. At this time, the growth is in a state of stagnation. Potted plants should be placed in the windowsill with sufficient light or closed balcony for cultivation, pay attention to water control, so that the basin soil is dry and not dry. No fertilizer.

7. Matters needing attention in Yushu Culture

The main results are as follows: (1) Yushu likes to be warm and sunny, and it can grow well under the condition of indoor scattered light, avoid strong light, and is prone to sunburn in hot summer, causing leaves to shrink and turn yellow.

(2) when the temperature rises in spring, the growth begins to resume, sufficient light should be maintained and the amount of water should be gradually increased. When the outdoor temperature is stable above 15 ℃, it can be cultured on a balcony with light but no rain. During the growth period, watering should be controlled to prevent the basin soil from being too wet to cause rot, and it is appropriate to water the soil after it is dry. Rain Water should reduce the frequency of watering in more weather.

(3) during the growth period, the over-long and over-dense branches should be pruned appropriately, the posture of the plant should be balanced and the tree should be strong. Move indoors in the middle of October, place in a warm place with sufficient light, and the minimum overwintering temperature should not be lower than 5 ℃. Watering should be strictly controlled to keep the basin soil from drying out. Turn the basin every half month to avoid the deviation of branches and leaves, affecting the appearance, such as lack of light, we should pay more attention to prevent damp and hot rotten roots and defoliation.

(4) keeping Yushu moderate water and fertilizer during its growing period, sufficient indoor light in winter, fresh air and stable temperature, and strong old plants can produce pink and white flowers with fragrance in winter and spring.

[tip] Yushu is very similar to the swallow palm, but they are two completely different plants. The difference is that the leaf edge of the swallow palm has a thin red edge, while the leaf edge of Yushu has no red edge.
