How to grow the eight Immortals? Propagation methods and Management points of eight Immortals

Recently, a florist friend asked: can the eight Immortals be planted in autumn? How do the eight Immortals reproduce? In fact, the eight Immortals is what we usually call hydrangea, which can also be called Ziyang flower. There are many colors, which are of great ornamental value. Let's briefly learn the culture method of eight Immortals.

I. Propagation methods

There are many ways to propagate the eight Immortals, such as striping, ramet and cutting.

Striping can be done all the year round. Choose the sturdy branches of the eight Immortals to be stuck in the right place with the crimping card, and they will soon grow new roots.

Ramets are generally chosen to be carried out in the vigorous spring and summer, and the 2-3 plants with strong growth are divided directly into another flowerpot, which can take shape after 2 months.

Cutting is generally carried out in May-June, select fast Lignification of robust branches, select a branch of 15 cm, retain 2-3 leaves in the lower part of the branches dipped in rooting powder, cuttings in the soil with river sand as the substrate, 1-2 months can grow new roots.

II. Fertilizer and water management

The eight Immortals are easy to grow and easy to manage. The eight Immortals like fertilizer and water, apply nitrogen fertilizer every other month in the growing season, apply phosphorus and potassium fertilizer before and after flowering, and spray foliar fertilizer during flowering. The eight Immortals like water, and they should be watered once a day in the peak growing season, 1-2 times a day after growing buds, and gradually reduce the number of watering times in the late growth period. Eight immortal flowers like shade, when the sun is strong, it should be placed in a semi-shady place, long-term direct sunlight is easy to cause leaves withered and yellow.

3. Pruning

After the eight fairy flowers bloom, they should be pruned in time in order to maintain a good plant type. generally, the redundant branches at the base are removed, and these branches can be reserved for cutting. Generally, there are 2-3 buds at the base, and when the new branch grows to 10 cm, it can pick the heart once, which is beneficial to the luxuriant branches and leaves of the eight Immortals.

The above is the breeding and cultivation methods of eight Immortals, interested florists can have a look, if you have a better experience to share, you can leave a message at the bottom of Huinong!

Main points of propagation of eight immortal flowers

The difficulty of artificial cultivation of eight Immortals is not high, but many flower friends often want to breed by themselves after planting their own eight Immortals. The propagation method of eight Immortals is very conventional, and cutting is the favorite and most commonly used breeding method for flower friends.

Eight immortal flowers

The eight Immortals are easy to survive when they reproduce. The methods of split propagation, striping propagation, cuttings propagation and tissue culture propagation can be used for propagation.

Ramet propagation is carried out before plant germination in spring, the rooted branches and mother plants are separated into several plants according to root potential, old roots and overgrown roots are cut off, potted directly, watered and maintained in semi-shade, and daily management is carried out after new buds germinate. In order to improve the survival rate, rooting powder can be used to soak the roots of the seedlings.

Striping propagation is suitable to be carried out before the plant germinates in spring, select 1-2-year-old strong branches, lightly cut under the node, cause local trauma, cut off the leaves buried in the ground, bury them in the soil, fix the branches, moisturize, and begin to take root in about 30 days. In the following spring, it was cut off from the mother plant and transplanted with soil.

Cutting propagation should be carried out in spring and summer, and greenhouse conditions can be carried out in four seasons. Select twigs, lignified or semi-lignified sturdy branches, cut into cuttings, the length of the cuttings is 10mur15cm, cut off the lower leaves, cut off the upper leaves, keep the substrate humidity and proper shade after cutting, and take root in about 30 days under 15murl 251 environment. 1 is available before insertion. Soak the cuttings base in 1% naphthalene acetic acid aqueous solution for 10 seconds, or soak the cuttings base with rooting powder to increase the survival rate.

The technique of tissue culture and propagation of Baxian flower is widely used in modern flower production. The induction medium is MS+6-BA 1.0 mg / L + NAAO.l mg / L, and the rooting medium is l/2MS+NAA0. 5mg can quickly produce a large number of high-quality seedlings.

Introduction of Hydrangea macrophylla Immortals (scientific name: Hydrangea macrophylla), also known as Hydrangea, Ziyang Flower, is a plant of the genus Saxifragaceae. The eight Immortals flowers are white and plump, large and beautiful, and their colors can be red and blue, pleasing to the eye and spirit. They are common potted ornamental flowers and trees. The eight Immortals were cultivated earlier in China, and they were planted in the gardens in the south of the Yangtze River built in the Ming and Qing dynasties. The parks built at the beginning of the 20th century are also inseparable from the planting of eight Immortals. Modern parks and scenic spots are planted in pieces to form a landscape. The morphological characteristics of eight Immortals are deciduous shrubs with stout branchlets and obvious lenticels. Leaves are large and thicker, opposite, Obovate, margin coarsely serrated, leaf surface bright green, leaf back yellowish green, petiole stout. The flowers are large and consist of many sterile flowers in the terminal corymb. The color of the flower is changeable, white at first, turning blue or pink gradually. 1-4 m tall; stems often emit many radiating branches at base to form a round shrub; branches Terete, stout, glabrous, with a few oblong lenticels. Leaves papery or subleathery, suborbicular or broadly ovate, 1.4-2.4 cm long and 1-2.4 cm wide, pink, light blue or white; pregnant flowers few, with pedicels 2-4 mm long; calyx tube obconical, 1.5-2 mm long, sparsely crimped pubescent with pedicels, calyx teeth ovate-triangular, ca. 1 mm; petals oblong, 3-3.5 mm long. Stamens 10, subequal, not prominent or slightly prominent, anthers oblong, ca. 1 mm; ovary mostly inferior, style 3, fruiting ca. 1.5 mm, stigma slightly enlarged, semicircular. Capsule immature, long gyro-shaped, style ca. 4.5 mm, apical protuberance ca. 1 mm, approximately equal to 1 × 3 of capsule length; seeds immature. The florescence is from June to August. [1] 4-11.5 cm wide, apex cuspidate, mucronate, base obtusely rounded or broadly cuneate, margin coarsely dentate above base, both surfaces glabrous or only sparsely curly pubescent on both sides of lower midvein, often with a little bearded between axils of veins; lateral veins 6-8 pairs, straight, oblique upward or slightly arched near upper margin, flat above, slightly convex below, reticulate, obvious on both surfaces. Petiole stout, 1-3.5 cm long, glabrous. Corymbose Cymes subglobose, 8-20 cm in diam., with short involucral pedicels, branches stout, subequal, densely pubescent, flowers dense, mostly sterile; sterile sepals 4, broadly ovate. Ecological habits of eight Immortals the eight Immortals are native to China and Japan. Like warm, moist and semi-overcast environment. The optimum temperature for the growth of eight Immortals is 18-28 ℃, and the winter temperature is not lower than 5 ℃. Flower bud differentiation takes 6-8 weeks under the condition of 5-7 ℃. The temperature of 20 ℃ can promote flowering, maintain 16 ℃ after anthesis, and prolong the flowering period. But the heat makes the flowers fade quickly. The soil of the eight immortal pots should be kept moist, but it should not be watered too much, especially in the rainy season to prevent rotting roots caused by waterlogging. It is better to dry the eight Immortals indoors in winter. If it is too wet, the leaves will rot easily. The eight Immortals are short-day plants, which are treated in the dark for more than 10 hours a day and form flower buds in about 45-50 days. Usually cultivation should avoid the hot sun, and 60%-70% shading is the best. The sandy loam with loose, fertile and well-drained soil is better. However, the flower color of Baxian flower changed greatly due to the change of soil pH. In order to deepen the blue, aluminum sulfate can be applied during bud formation. To keep pink, lime can be applied to the soil. The distribution area of eight Immortals is native to Japan and Sichuan, China. It was introduced to England in 1736. Cultivation is more common in Europe, Holland, Germany and France. Red, blue and purple flowers can be seen in florists. There are also a lot of Immortals planted in front of small gardens and buildings. RamppJungpflanzen is a world-famous manufacturer of eight Immortals, and it is also the most important cultivation and production unit of new varieties of eight Immortals. Secondly, the door model text company of the Netherlands and the Yag nursery in Israel are also the main producers of eight immortal flowers. In Asia, mainly Japan is rich in eight fairy flowers, in horticultural shops in a wide variety of eight fairy flowers, you can see many strange new varieties, expensive, all as a family potted ornamental. The propagation methods of eight Immortals are commonly used in ramet, striping, cutting and tissue culture. Ramet propagation: it should be carried out before sprouting in early spring. Separate the rooted branches from the mother plant, pot directly, watering should not be too much, maintain in the semi-shady place, wait for new buds to sprout and then transfer to normal maintenance. Striping propagation: when the bud germinates, it can grow after 30 days, cut off with the mother plant in the following spring, transplant with soil, and blossom in the same year. Cutting propagation: carried out in the rainy season. Cutting the top twigs, about 20 cm long, picking off the lower leaves, cutting at the appropriate temperature of 13-18 ℃, rooting 15 days after cutting. Tissue culture propagation: using dormant buds as explants, adventitious buds were cultured on MS medium supplemented with 6-benzylaminoadenine 0.8mg / L and indole acetic acid 2mg / L after regular disinfection. When the seedling height was 2cm to 3cm, it was transferred to 1/2MS medium supplemented with indole acetic acid 2.0mg / L, and grew into complete plantlets. Potted eight Immortals are often used in pots of 15cm and 20cm. Potted plants should be fully watered after sprouting in spring to ensure that the leaves do not wither. During the flowering period from June to July, there should be sufficient fertilizer and water, fertilizing once a month or using "Huiyou" 21 Mel 7 Mel 7 acid fertilizer. When the light is too strong in midsummer, proper shading can prolong the flowering period. The stem of the flower is removed after flowering to promote the formation of new branches. The flower color is affected by soil acidity and alkalinity, acid soil flower is blue, alkaline soil flower is red. Change the basin every spring. Trim properly to keep the plant shape beautiful. Cultivation techniques and management of Baxian flowers like warm and humid, not resistant to drought, but also avoid waterlogging; like semi-shady environment, not cold-resistant, suitable for growing in fertile, well-drained acidic soil. The acidity and alkalinity of the soil had a very obvious effect on the flower color of the eight fairy flowers. when the soil was acidic, the flower was blue; when the soil was alkaline, the flower was red. It is better to cultivate Baxian flower in acidic soil (PH4-4.5). Eight immortal flowers like fertilizer, during the growth period, generally apply rotten thin pancake fertilizer and water every 15 days. In order to maintain the acidity of the soil, ferrous sulfate of 1% muri 3% can be added to the fertilizer solution. Regular watering of alum fertilizer and water can make the plant branches and leaves green; the application of 1-2 potassium dihydrogen phosphate during the bud period can make the flowers bright and colorful; the application of cake fertilizer should avoid summer days, so as not to cause diseases and insect pests and damage the root system. Baxian flower has hypertrophic leaves, luxuriant branches and leaves, and needs more water. In the spring, summer and autumn of the growing season, it is necessary to irrigate enough water to keep the basin soil moist. The summer weather is hot, evaporation is large, in addition to watering enough water, but also spray water to the leaves every day. The root of the eight Immortals is fleshy root, watering should not be excessive, avoid stagnant water in the basin, otherwise the root will rot. After September, the weather is getting colder and cooler, so the amount of water should be reduced gradually. Frosts Descent moved into the room, the room temperature should be kept at about 4 degrees. Remove the leaves before entering the room to avoid rotten leaves. It is appropriate to put the plant in the sunny place indoors in winter, and it is appropriate to leave the room after Grain Rain in the second year. Baxian flower is an ideal potted flower which is easy to manage and cultivate because of its extensive management and few diseases and insect pests. [3] the flowers of the eight Immortals, also known as Hydrangea, bloom from June to July. Flowers blooming white, gradually turning pink or blue, large globular, composed of sterile flowers. The flowers are in full bloom, like snowflakes pressing trees, charming and moving. It has dense branches and leaves, fleshy roots and strong adaptability. it can not only be planted in a corner of the family courtyard and patio, but also be potted to beautify the balcony and windows to add color. The eight Immortals prefer semi-shade and humid environment and are not very hardy. Summer heat avoid the scorching sun, otherwise the leaves are easy to scorch and yellow, not suitable for excessive dryness, good born in humus-rich, moist, well-drained light loam. Branches and leaves are easy to wilt and wither after frost, and the aboveground parts of open-field cultivation die in winter, and new shoots germinate from the roots and then blossom the following year. If they are potted in the greenhouse, they can remain evergreen. The key points of maintenance and management of the four seasons are as follows. Spring: the dead branches of potted plants should be pruned and the soil should be turned over to change the soil. After taking the pot, the thin liquid fertilizer based on nitrogen fertilizer can be applied once or twice, which can promote the germination of branches and leaves. Summer and autumn: should be placed in the semi-shade or under the curtain to prevent the scorching sun and prevent the leaves from yellowing and anxiety. Topdressing is applied once or twice before and after flowering to promote the reproduction of chlorophyll flowers. After the flower fade, the pedicel should be repaired in time to keep the posture beautiful. The potted soil is often moisturized, but it is necessary to prevent stagnant water after rain to prevent the fleshy roots of Immortals from rotting because of too much water. Winter: after the beginning of winter, the plants cultivated in the open field should keep the soil warm so that they can survive the winter safely; the potted plants can be placed in a warm place facing south and without cold wind. Although the withered leaves fall off in winter, the roots and branches still survive, and new leaves germinate in the next spring. [5] to change the soil and trim the potted Immortals, it is generally necessary to turn the pot and change the soil once a year. It is appropriate to turn the basin and change the soil in the first ten days of March. The new soil was prepared with 4 parts of foliage soil, 4 parts of garden soil and 2 parts of sand, and then an appropriate amount of rotten cake fertilizer was added as base fertilizer. When changing, it is necessary to prune the roots of the plant, cutting off rotten roots, rotten roots and overlong roots. After the plant is moved into the new pot, the soil should be compacted, watered and placed in a shaded place for about 10 days, and then moved outside for normal management. In order to make the potted eight Immortals have a beautiful crown and blossom more, it is necessary to prune the plants. The eight Immortals are thriving and resistant to pruning. Generally can be from the survival of the seedlings, grow to 10-15 cm high, that is for heart-picking treatment, so that the lower axillary buds can germinate. Then the four new shoots in the middle and upper part were selected and all the axillary buds in the lower part were removed. When the new branch grows to 8-10 cm, the second coring is carried out. The eight Immortals usually bloom on biennial strong branches. after flowering, the old branches should be cut short and 2-3 buds should be retained to limit the plant growth and promote the growth of new shoots. Cut off the top of the new shoots after autumn to stop the branches from growing so as to survive the winter. After such pruning, the plant type is more beautiful, which greatly enhances the ornamental value. The main diseases of Baxian flower were wilt, powdery mildew and leaf spot, which were sprayed with 65% Dysen zinc wettable powder 600 times. Insect pests are harmful to aphids and bug bugs and can be sprayed with 1500 times of omethoate EC. Classification of varieties of eight Immortals 1.

The garden can be placed in the shade of sparse trees and beside the avenue, and planted on the shady hillside. Because of the low demand for sunlight, it is most suitable to be planted in a small courtyard with poor sunlight. It is ideal to plant two plants at the entrance of the building, a row along the building, and clusters in a corner of the courtyard. It is more suitable for planting flower hedges and flower borders. If the whole bouquet is cut off and inserted into the room, it is also a first-class embellishment. It is more elegant and interesting to hang the bouquet in the bed tent. According to legend, the cultural background of the eight Immortals once went to Yaochi to attend the Queen Mother's peach party and came back to pass through the East China Sea, alarming the Dragon King of the East China Sea. The Dragon King's nine sons were ordered to spy on the sea. Among them, the seventh prince of the Dragon King saw that he Xiangu was beautiful in the eight Immortals, so he stirred up trouble on the sea and took the opportunity to snatch he Xiangu into the Dragon Palace. The other seven immortals were furious and each raised their magic weapons and turned them into seven red scale fire dragons, spurting a scorching sun on the surface of the sea, and suddenly the sea was boiling. The Dragon King of the East Sea felt very hot in the Dragon Palace. When he heard a deafening noise outside, the Dragon Palace shook even more. After asking the reason, he angrily reprimanded the seventh prince, tied him up with his own hands, and invited he Xiangu to sit in the dragon sedan chair and be carried by the other eight dragons. Rise to the sea to apologize to the immortals. When the seven immortals saw that he Xianguu returned safely, the Dragon King personally brought the seven princes to apologize, and their anger was extinguished, indicating that they were willing to turn swords into friendship. The Dragon King apologized for offering flowers to the eight Immortals. The eight Immortals brought the flowers to China, and the flowers were clustered like a big hydrangea. Sure enough, the flowers were beautiful, colorful and extraordinary, and beautiful scenery was added to the garden. People know that this kind of flower is brought by the eight Immortals, so they affectionately call it the "eight Immortals". The language of the eight Immortals is named after the eight Immortals, so it means "the eight Immortals cross the sea, each showing their magical powers." in Britain, this flower is described as "ruthless" and "cruel". In China, this flower is compared to hope, health, endurance love, pride, cold love, happiness and reunion.
