How to breed hydrangeas, how to breed hydrangeas

Hello! <>

Hydrangea cultivation method:

1. Soil blending method.

Hydrangeas like to grow in loose and breathable, humus-rich slightly acidic soil, and it is recommended to use a mixture of humus, river sand, and garden soil to maintain hydrangeas. When mixing soil, it is necessary to disinfect the soil and add an appropriate amount of organic fertilizer, so as to ensure the growth of hydrangeas.

2. The temperature is suitable.

Hydrangea likes a warm environment, its most suitable temperature for growth is between 20 and 25, daily maintenance, summer needs to be shaded in time and strengthen ventilation, control the temperature does not exceed 30, winter is recommended to move it indoors to keep warm, control the temperature is not less than 5, so that the plant can successfully overwinter.

3. Sufficient light.

Hydrangea loves light, it is recommended to put it on the balcony and windowsill at home to maintain, to ensure that sufficient light is more conducive to the growth of plants and the differentiation of flower buds. However, the light is strong in summer, so it is necessary to take corresponding shading measures to avoid damage caused by strong light burning the leaves.

4. Reasonable fertilizer and water.

Hydrangea growth is inseparable from reasonable watering and fertilization, in the growing season of the plant need to be watered 2 3 times a week, and every 20 days need to apply a thin liquid fertilizer to ensure the growth of the plant. Before flowering, it is also necessary to apply phosphorus and potassium fertilizer once, which can achieve the purpose of promoting and preserving flowers.

Cuttings propagation: from February before germination, you can start cuttings (flower friends in other seasons can also try, surprises are always after trying), select semi-lignified branches, about 20 cm long, remove the lower leaves, cut off the flower buds with flower buds, cuttings at a temperature of 13-18, 15 days after cuttings to take root. Of course, there are also flower friends who have taken root.

Dividing propagation: It should be carried out before budding in early spring. Separate the rooted branches from the mother plant, directly potted, watering should not be too much, maintain in semi-shade, and then transfer to normal maintenance after germinating new shoots.

High-pressure propagation: carried out when the buds germinate, can grow after 30 days, cut off from the mother plant in the spring of the following year, transplanted with soil, and can bloom in the same year. The specific operation method is very simple, peel off a circle of skin from the branches in a ring, and then wrap them with peat or other soil.

During the flowering period from June to July, fertilizer and water should be sufficient, and fertilizer should be applied once every half month"Huiyou"21-7-7 acid fertilizer. When the sun is too strong in midsummer, proper shade can prolong the flowering period. After flowering, the flower stems are removed to promote the production of new branches.

The flower color is affected by the pH of the soil, and the acidic soil flowers are blue, and the alkaline soil flowers are red. Repotting is done once a year in the spring. Prune properly to keep the plant in shape.

Hydrangea does not have strict soil requirements, and generally uses loose and fertile sandy loam soil to ensure good ventilation and drainage, and basically there will be no problems. It can be mixed with 4 parts of humus soil + 3 parts of garden soil + 2 parts of river sand + 1 part of cake fertilizer, or mixed with 6 parts of humus + 3 parts of furnace ash + 1 part of cake fertilizer. The flower color of hydrangea will be affected by the pH of the soil, so the flower color of hydrangea can be adjusted, and the pH of the soil can be adjusted to control the flower color.

Hydrangea is a short-day flowering plant, which can be exposed to bright direct light every day, and cannot grow in a shady place for a long time, avoiding the scorching sun in summer, and it is probably best to shade 60 70.

In spring and autumn, the growth is fast and the water requirement increases, and it is necessary to water about once every 2 3 days. In summer, the water evaporates quickly, so it needs to be watered once a day, when it is cool in the morning and evening. In winter, the water demand is reduced due to low temperatures, so watering according to the dryness of the potting soil, and then watering when it is completely dry, about 3 or 4 times throughout the winter.

In planting or repotting, slow-release fertilizer, organic fertilizer or bone meal can be applied as a base fertilizer, which can provide nutrients for the growth of plants. Fertilize hydrangeas with thin fertilizer and apply frequently, and each fertilizer should not be excessive or too thick. In the growth period of hydrangeas, nitrogen fertilizer is applied once every 2 to 3 weeks, supplemented by phosphorus and potassium fertilizer.

During the growth and development of flower buds, potassium dihydrogen phosphate solution can be applied 2 or 3 times in a row to make the flowers larger and brighter, and fertilization will be stopped after the flower buds are color-clearing.

1. In the process of hydrangea maintenance, the soil is dry and dry, but the soil can not be allowed to accumulate water, which will lead to poor breathing of the roots, fertilizer and rot, and in serious cases, it will lead to the death of the plant. Pay attention to the rainy season, and keep the plants out of the rain.

2. Try not to pour water on the leaves or flowers for watering, the water will remain on the leaves or flowers for a long time, and the leaves and flowers may rot.

3. The whole plant of hydrangea is toxic, and attention needs to be paid in the maintenance process. The above is the hydrangea breeding methods and precautions, and the management of all aspects of maintenance must be in place to ensure that the hydrangea flowers are large and bright, and bloom a large area.

1. Soil preparation: When cultivating hydrangeas, the soil can be mixed with humus, sandy soil and cake fertilizer. 2. Sunlight is suitable

In the spring, the plants are kept outdoors in semi-shade. 3. Scientific watering: watering more in spring and summer to keep the soil moist, and do not accumulate water in the soil.

4. Precautions: Regularly add salt-free vinegar during maintenance.

1. Soil preparation

Hydrangea grows well in loose and fertile slightly acidic or slightly alkaline soil, when cultivating plants, the soil can be mixed with humus, garden soil, sandy soil, cake fertilizer, or mixed with humus soil, sandy soil, cake fertilizer in accordance with the ratio of six to three to one.

2. Sunlight is suitable

Hydrangea likes shade but does not like the sun, in the process of maintenance, move to the outdoor semi-shade in the spring to maintain, the summer light intensity is high and need to take shading measures, you can use the shade net for shading or put it in the back of the sun, autumn and winter need to put the plant in the indoor sunny place.

3. Scientific watering

Hydrangeas like a moist environment, but afraid of waterlogging, so in the maintenance of the need to control the amount of watering, spring and summer can be watered, keep the soil moist, do not appear soil waterlogging, autumn and winter to reduce the amount of watering, keep the soil slightly moist, in order to prevent frost damage.

4. Precautions

In the process of maintaining hydrangeas, it is necessary to regularly add vinegar without salt to maintain the slight acidity of the soil, and in time to pluck the hydrangea during the growth period to promote the growth of side branches, and shorten the plant before winter, which helps the hydrangea to survive the winter.

When cultivating hydrangeas, humus, garden soil, river sand, and cake fertilizer can be mixed into a substrate for cultivation. Hydrangeas can be placed in a bright place for maintenance every day, and shade should be done when the light is too strong. During the growth period of hydrangeas, water can be applied every 2 to 3 days, and thin manure cake water can be applied every 15 days or so to replenish nutrients.

To cultivate hydrangeas, it is necessary to choose soil with rich nutrients and strong air permeability as the substrate for cultivation. Leaf humus, garden soil, river sand, and cake fertilizer can be compared to 4:3:

The 2:1 ratio is mixed to make a substrate for cultivation. After the soil preparation is completed, an appropriate amount of well-decomposed organic fertilizer can be added to the soil to improve the fertility of the soil.

Hydrangea has a certain resistance to negative, daily hydrangea can be placed in the semi-shade of the room for maintenance, summer when the light is too strong, can be properly shaded. The light of spring, autumn and winter is relatively soft, and the hydrangea can be placed in a bright place for maintenance, and about 5 hours of light can be given to promote the flower bud differentiation of the hydrangea.

Hydrangeas are suitable for growing in a humid environment, but they are not resistant to waterlogging, so the amount of watering should be strictly controlled when watering hydrangeas daily to ensure that the soil is in a slightly moist state. In the spring, it can be watered every 2 3 days, and the watering amount needs to be appropriately reduced in autumn and winter, and watering every 3 5 days can meet the regrowth needs of hydrangeas.

Hydrangeas are suitable for growing in a fertile environment, and during the growth period of hydrangeas, thin fertilizer cake water can be applied every 15 days or so to supplement nutrients. In the process of fertilization, the ferrous sulfate solution mixed into the fertilizer can be turned into fertilizer water for watering, so that the hydrangea can bloom more colorful flowers.

1. Choose the right soil.

2. Ensure the appropriate temperature.

3. Ensure sufficient moisture.

4. Choose the right amount of fertilizer.

5. Sufficient light is required.

1.Choosing the right soil Hydrangeas prefer fertilizer and moisture, especially those with good drainage and humus-rich slightly acidic soils, which are most suitable for hydrangeas, and there are many organic fertilizers in this soil that can make hydrangeas grow healthier.

2.Ensure the right temperature Hydrangea also has requirements for the temperature of the growing environment, generally between 18 and 28, in winter it is best not to be lower than 5, and if you want to promote its flowering, 20 temperature is the best choice.

3.Ensure sufficient moisture Hydrangeas prefer moist environments and need plenty of water to grow quickly, and while watering in summer, they also need to ensure the humidity of the surrounding environment. Of course, you also need to be careful not to water too much, and it is not okay if there is water.

4.Choose the right amount of fertilizer In the most vigorous stage of hydrangea growth, it is necessary to fertilize to give enough nutrients, it is best to apply plum half a month to apply rotten thin cake fertilizer water, which will be bigger and more brilliant in the future.

5.Sufficient light is needed In winter, the growth rate will be very high due to the low temperature, so it is best to keep the hydrangea on the balcony to get enough light while keeping warm. In summer, when the yang light is too hot, it is placed in a cool place.

Hydrangea likes warm, moist and semi-shady environments, is afraid of drought and waterlogging, is not cold-tolerant, likes fertilizer and moist, well-drained light loam soil, but has strong adaptability. Therefore, the soil is loose, fertile and well-drained sandy loam.

The acidity and alkalinity of the soil have a great influence on the flower color of hydrangea, which is mostly blue in acidic soil and red in alkaline soil. The potting soil should be kept moist, but the watering should not be too much, especially in the rainy season, attention should be paid to drainage to prevent root rot caused by waterlogging. In winter, indoor potted plants are preferably slightly drier.

Repot once a year in spring, prune properly, and keep the plant beautiful.

If you want hydrangeas to be raised well, you must pay attention to the temperature and light of the surrounding environment. Hydrangeas can only grow normally between 15 and 27 degrees Celsius, so try to move it indoors to a sunny place in winter, and the minimum room temperature should not be lower than 5 degrees.

Otherwise, the hydrangea will freeze to death or stop growing. In the summer, it is necessary to focus on cooling and shading the leaves, so as not to burn the leaves, too strong sunlight will only cause the leaves to change color or even wither.

Precautions for hydrangea farming.

Hydrangeas prefer acidic soils, are not tolerant to barrenness, and will grow poorly in alkaline soils, with yellowish branches and leaves. Flower color is also affected by the pH of the soil.

In early October, the plants should be moved indoors for maintenance, properly controlled water, and kept at a temperature of 5 to promote their dormancy. Remove some of the leaves before moving indoors to avoid leaf rot and infection with germs.

It is usually topped twice during the growth phase to promote branching. After flowering, the old branches are cut short to control the height of the plant. Before winter, the plants are cut short again to facilitate overwintering.

Cultivation method of embroidered cave covered bulbs.

1. Soil. How to breed hydrangeas? The first thing to pay attention to in the hydrangea cultivation method is the soil in which the hydrangea is grown. Soils are preferably loose, fertile and well-drained sandy loam.

2. Watering. The potting soil for hydrangea planting should be kept moist, but the watering should not be too much, especially in the rainy season, attention should be paid to drainage to prevent root rot caused by waterlogging. In winter, indoor potted plants are preferably slightly drier. If it is too wet, the leaves are perishable.

3. Illumination. Hydrangea is a short-day plant, and it can form flower buds in about 6 weeks when it is left in the dark for more than 10 hours a day. Usually cultivate to avoid the scorching sun, 60 70 shade is ideal, and the appropriate shade can prolong the flowering period when the sun is too strong in midsummer.

4. Temperature. When cultivating hydrangeas, one of the more important points to pay attention to in the cultivation method of hydrangea is the growth temperature of hydrangeas. Usually the suitable temperature is 18 28, and the winter temperature is not lower than 5.

Flower bud differentiation takes 5 7 conditions for 6 8 weeks, 20 temperature can promote flowering, maintain 16 after flowering, can prolong the flowering period, pay attention to high temperature to make the flowers fade quickly.

5. Fertilization. The flowering period of hydrangea is 6 to 7 months, and the fertilizer and water should be sufficient during the flowering period, and the fertilizer should be applied once every half month.

6. Pruning. After the hydrangea blooms, it is necessary to pay attention to removing the flower stems to promote the production of new branches, and proper pruning can maintain the beautiful shape of the plant.

The above is the method of hydrangea breeding, in addition to these, hydrangea breeding should also pay attention to the management of pests and diseases, as well as the breeding method of hydrangea and so on.

Cultivating hydrangea should be prepared with 5:4:1 humus soil, river sand and cake fertilizer mixed humus soil, apply thin cake fertilizer once every half month, and water it once every 2 3 days, maintain a suitable temperature of 18 28, so that it can accept an appropriate amount of astigmatism and grow vigorously.

Do a good job of pruning and topping, spray pesticides in time for pest control, and also carry out cuttings to make them vigorous.

Hydrangeas grow best on humus soils, so you need to choose 3:3:2:

2. The mixed soil of humus, river sand, garden soil and cake fertilizer can also be used according to the 5:4:1 prepared humus, sand soil and cake fertilizer mixed soil.

When breeding, pay attention to changing pots once a year to make it grow better.

Hydrangeas in the growth period have high nutrient requirements, so they should apply thin cake fertilizer once in about half a month, and apply superphosphate about twice in the flowering period to make them bloom better. Usually it can be watered once in about 2 or 3 days, and its frequency can be increased in summer, once in the morning and once in the evening.

In the cultivation method of hydrangeas, it is necessary to provide it with a suitable temperature of 18 28, and it is best to maintain a temperature of more than 5 in winter, and it should be placed under scattered light, receive sufficient light to grow vigorously, but do a good job of strong light shading in summer to avoid sunburn.

When breeding, it is also necessary to pluck the topping when it grows to a certain height, respectively, when the new branches are 12cm long and the branches are 10cm long, and the residual branches should be pruned in time to make them grow healthily. And to do a good job of insect control, spray zebsen zinc wettable powder and dimethoate emulsifiable concentrate for effective control.

In the process of cultivating hydrangeas, it can also be propagated by cuttings, generally in spring and autumn, the suitable branches are cut down, keep its length between 10 15cm, and only 2 3 leaves at the upper end, and then insert it into the soil for maintenance, 10 15 days or so the branches will grow new roots.
