Cultivation and Culture methods of Hydrangea

Hydrangea, because of its corymbose inflorescence with most sterile flowers, as few as eight, many are innumerable names; and because of its tight inflorescence, shaped like hydrangea, it is named hydrangea, it has two types of flowers, small flowers in the middle, bisexual, fruiting after flowers; large flowers outside, scattered around, and no stamens, only play the role of attracting insects and setting off the flower core. Sterile flowers developed from 4 sepals, initially green-white, and then gradually changed to pink to blue-purple. Each flower is small, but the whole inflorescence can be up to 15 cm in diameter. You can watch it from June to August. Varieties cultivated in the garden also have Douqiu, also known as Hydrangea, inflorescences are all sterile flowers, ornamental effect is better; Ziyang flower, corymbose inflorescences are the largest, up to 20 cm, inflorescences are almost all sterile flowers, flowers and colors are all blue-purple, is the best variety of hydrangea; silver-edged hydrangea, flowers with hydrangea, but the leaf edge is white, flowering mainly, leaves can also be seen when there is no flower.

Hydrangea originated from the Yangtze River Basin in China to Guangdong and Fujian. Sex likes warmth, shade and wetness; requires fertile, humus-rich and well-drained moist soil, micro-acid, micro-alkali and neutral soil can grow well, but the alkaline is heavy, so the ph value is 7. More than 5% of the land will grow poorly. It can be cultivated in the open field in the south of the Huaihe River basin. In the north, the outdoor pot plant overwinters indoors, and the lowest temperature should be above 10 degrees. If you can maintain the room temperature, you can watch the flowers all the year round. Cuttings, strips and ramets can be used for propagation, and transplanting is the easiest, hardwood and tender wood can be used; it can take root in about one and a half months at a temperature of about 20 degrees and 80% relative humidity, and can be put on the basin after 2 months. Pay attention when cutting, hydrangea is a negative plant, must not be too exposed to the sun. Matters needing attention in cultivation, management and culture of hydrangea

Hydrangea is known as ball orchid, also known as eight Immortals, Ziyang Flower, Seven changes, Hydrangea, Noodle Flower, originated in Sichuan, China and Japan. It is a deciduous shrub of Hydrangea of the family Hydrangea of Cornus. The flowers are almost asexual, and the so-called "flowers" are just sepals. The eight Immortals were cultivated earlier in China, and hydrangea was planted in the gardens in the south of the Yangtze River built in the Ming and Qing dynasties. The park built at the beginning of the 20th century is also inseparable from the planting of hydrangea. Modern parks and scenic spots are planted in pieces to form a landscape. Artificially cultivated hydrangea flowers are colorful, with blue, white, purple, pink, pink and other colors, is a common ornamental flowers and trees.

Growth habits of Hydrangea

We must first understand the growth habits of hydrangea before we can pertinently master the breeding methods of hydrangea. Hydrangea is native to the Yangtze River Basin in China and is fond of warm, moist and semi-shady environment. Afraid of drought and waterlogging, it is not cold-resistant. In cold areas, the aboveground parts wither and die in winter, and new shoots will not sprout again until the next spring. Hydrangea likes the light loam which is fat, moist and well drained, and has strong adaptability. The acidity and basicity of the soil had a great influence on the flower color of hydrangea, which was blue in acidic soil and red in alkaline soil.

Propagation method of Hydrangea

Cuttings, ramets, striping and grafting are commonly used for propagation, mainly cuttings. During the Meiyu period, strong twigs on young mother trees can be selected as cuttings, with nodes at the base of cuttings, stained with mud, about 20 cm long, and the lower leaves can be removed. The suitable temperature of cuttings is 1 3-18 ℃, shade is needed after cutting, it is often kept moist, rooting takes place in about 15 days to 1 month, and can be transplanted in the second year after survival. Ramet propagation 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 can be carried out during bud germination, grow after 30 days, cut off from the mother plant in the following spring, transplant with soil, and blossom in the same year. In general, high pressure is carried out from March to April in spring, and it can take root from June to July, and it can be cut and planted in the same year. Grafting propagation uses Qionghua seedlings as rootstocks, cutting in spring, easy to survive. Transplanting should be carried out after defoliation or before budding. The main branch is easy to sprout and grow, and it needs to be pruned properly after flowering to shape the tree.

Cultivation and Management of Hydrangea

The optimum temperature for the growth of Hydrangea 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. Hydrangea is a short-day plant, which is treated in the dark for more than 10 hours every day and forms flower buds in about 45-50 days. Potted hydrangea is commonly used in 15cm pots. Potted plants should be fully watered after sprouting in spring to ensure that the leaves do not wither. During the florescence from June to July, there should be sufficient fertilizer and water, and fertilization should be applied once a month. Usually cultivation should avoid the hot sun, and 60%-70% shading is the best. 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 sandy loam with loose, fertile and well-drained soil is better. However, the flower color is affected by soil acidity and alkalinity, acidic soil flowers are blue and alkaline soil flowers are red. The basin soil 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 indoor potted plants in winter. If it is too wet, the leaves will rot easily. Change the basin every spring. Trim properly to keep the plant shape beautiful.

Upper pot pruning of hydrangea

The propagation of hydrangea is carried out in spring and autumn, but it is the best in late spring and early summer (from the end of April to July). At this time, the hydrangea flowering period has basically ended in May, and new branches and leaf buds have grown after picking and pruning the leaves of the remnant flowers. at this time, the top branch and bud can be cut as cuttings. Cutting can also be carried out from late September to October, and many new branches and leaf buds will sprout after pruning the terminal buds of Hydrangea in early spring, and it is suitable for cutting propagation because of the cool weather.

1. In addition to the nursery bed made of brick, in order to facilitate moving and management, the foam box can be used as the seedbed. Cut a few holes at the bottom of the box and cover it with tiles, fill it with a layer of coarse sand and then put it into the culture soil (3 parts of sand and 2 parts of aseptic mountain soil), flatten it and cut it. Cut the cuttings into 10-15 cm segments, cut off the lower leaves of the terminal branches, leaving only the top 2-3 leaves. After cutting, tie up the cuttings. In order to make the cuttings heal and take root as soon as possible, soak the cuttings with a strong rooting agent (about 0.2 kg per packet of water) for 5 minutes and 10 minutes. After cutting, the soil around the branches should be pressed tightly with your fingers to make the cuttings closely combine with the soil. Then use a sprinkler to water once, as long as the bed soil is wet, there is no need to water, but to often spray on the cuttings leaves and keep the environment around the seedbed moist. If the weather is hot and sunny, shade should be built. In this way, under careful management, the wound began to heal for about 25 days, and new roots grew on the branches.

2. Pot cultivation and maintenance: Hydrangea has survived after about 25 days of careful management, and new leaf buds grow upward from the terminal bud, which must be separately planted and managed in pots. For the cultivation of hydrangea, the coniferous soil (with high acid content) is added with bran, and the compound fertilizer of nitrogen, phosphorus and potassium (according to the content of coniferous soil) is mixed and accumulated with the soil for more than half a year, and it can be used after opening and drying for several days before use. After the seedling survives, the top branch can be topped for the first time to promote the lower part to sprout new leaf buds: when several branches and buds grow to a certain length, top for the second time, and let their growth balanced and luxuriant, when the trunk is strong, only 3 or 4 branches are left to grow. During the period from pot survival to branch setting, it is necessary to apply fertilizer for 3 to 4 times, and the fertilizer is mainly potassium dihydrogen phosphate.

Disease and pest control of Hydrangea

1. The main diseases and insect pests of hydrangea are wilt, powdery mildew and leaf spot, which can be controlled by spraying 65% zinc wettable powder 600 times.

2. Insect pests are harmful to aphids and bug bugs, which can be sprayed with 1500 times omethoate EC.

Matters needing attention in the Culture of Hydrangea

1. Hydrangea is toxic, and accidentally eating the stems and leaves of hydrangea will cause colic, abdominal pain, diarrhea, vomiting, urgent inhalation, hematochezia and so on. In everyone's imagination, hydrangea is as edible as marshmallows and buns, but in fact, once you eat hydrangea, abdominal pain occurs a few hours later. other typical symptoms of poisoning include skin pain, vomiting, weakness and sweating, as well as reports of coma, convulsions and a breakdown of blood circulation in the body. Fortunately, an antidote for hydrangea poisoning has been developed. In addition, it should be noted that hydrangea is easy to cause allergies, generally not recommended in the bedroom. It is suggested that flower friends had better vary from person to person when planting flowers, choose flowers that they like and are harmless, do not grow too many flowers indoors, and pay attention to maintaining good ventilation.

2, hydrangea culture should pay attention to watering properly, the Beginning of Spring must let hydrangea have rain and dew, sunshine, water sooner or later.

How to raise Hydrangea the method of Family Culture of Hydrangea

Hydrangea flower shape is very similar to the ancient hydrangea hence the name, hydrangea flower shape plump, large and beautiful, its color can be red and blue, pleasing to the eye and spirit, is a common ornamental potted plant. How to raise the potted hydrangea in the family? Let's take a look at the family farming methods of hydrangea.

First, how to grow hydrangea

Hydrangea like warm, moist and semi-shady environment, afraid of drought and waterlogging, not cold-resistant, like fat, moist, well-drained light loam, but strong adaptability. Therefore, it is better to use loose, fertile and well-drained sandy loam. The acidity and basicity of the soil had a great influence on the flower color of hydrangea, which was blue in acidic soil and red in alkaline soil. The basin soil 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 indoor potted plants in winter. Change the basin every spring and trim it properly to keep the plant shape beautiful.

If you want to raise hydrangea well, you must pay attention to the temperature and light of the surrounding environment. Hydrangea can only grow normally between 15 and 27 degrees, so try to transfer it to a sunny place indoors in winter, and the lowest temperature at room temperature should not be lower than five degrees, otherwise the hydrangea will freeze to death or stop growing. In summer, we should focus on cooling and shading, so that the leaves will not be scalded. Too strong sunlight will only cause the leaves to change color or even wither.

II. Culture methods of Hydrangea

1. Soil: loose, fertile and well-drained sandy loam is the best soil for hydrangea planting. However, the flower color is affected by soil acidity and alkalinity, acidic soil flowers are blue and alkaline soil flowers are red.

2. Watering: the potted soil planted with hydrangea 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 indoor potted plants in winter. If it is too wet, the leaves will rot easily.
