How to maintain hydrangeas in summer, how to raise hydrangeas in summer

The summer hydrangea maintenance method is as follows:

When the sun is strong in summer, hydrangeas do not accept strong light, so if you do not do a good job of shading in summer, you will be burned by it, and the shade range is best around 65%. It should also be watered with more water, and the leaves should also be sprayed with water to ensure that the plant absorbs enough water. It does not like high temperatures, so it should be cooled down properly in the summer.

Hydrangeas can generally be pruned after mid-August, and should not be pruned after September. Pay attention to the time, do not prune too early or too late, otherwise it will affect the next year's flowering.

Watering hydrangeas in summer requires timely watering and sufficient amounts to meet the hydrangea's water needs. Choose early in the morning or after 6 p.m., and do not water directly on the branches and leaves. The water quality is clean and clean, and if it is irrigated with tap water, it will be allowed to stand for 1 or 2 days to volatilize chlorine before use.

1. Watering method

In summer, the temperature is relatively high, and the amount of water evaporation is relatively large. Therefore, when watering hydrangeas in summer, it is necessary to water them in a timely and sufficient amount. However, the watering time should be selected early in the morning or after 6 o'clock in the evening, so that the temperature has less impact on the moisture, the soil can maintain a moist state, and the absorption capacity of hydrangeas is better.

2. Pay attention to watering

Hydrangea absorbs water through the root system, conserves water, and then transports water to the leaves and branches through the transmission of its own branches and stems, so watering should be watered in the soil, and can not be directly irrigated on the leaves or buds, which can easily cause hydrangea to have leaves wilting.

3. Water quality selection

The water quality used to water hydrangea is mainly clean natural rainwater or snow water, and mineral water, purified water, etc. If you want to use tap water for irrigation at home, let the tap water stand for 1 or 2 days to volatilize the chlorine gas before use. The slightly acidic water quality is helpful for the growth of hydrangeas.

Hydrangeas should be paid attention to when maintaining in summer:Attention to shade in summer, careful fertilization in summer, pruning in mid-summer, attention to spraying fungicides, pruning after flowering.

1. Pay attention to shade in summer

Hydrangeas are more like the sun, but in the hot summer, they need proper shade, give more light in the morning or evening, and when the temperature is high at noon and in the afternoon when the light is too strong, pay attention to blocking the sun, if the sun is too hard, there will be some sunburn on the leaves. If sunburn appears on the leaves, it is basically impossible to recover.

Hydrangea potted plants should be properly shaded in the summer, and the best way is to move to the shade of a tree at noon and in the afternoon. If you are tending hydrangeas on a balcony or patio, you can put a shade net on it, and at the same time avoid sun exposure, but also give it more soft light.

2. Fertilize carefully in summer

In summer, if you can plant hydrangea potted in the shade of a tree, or pull a shade net for it, the environment is well ventilated, there is more light, it can continue to grow, at this time you should continue to supplement it with fertilizer, but the concentration should be lower, you can use Hua Duoduo No. 1 and Hua Duoduo No. 2, every 1 to 2 weeks to supplement 1 time, you can meet its growth needs, the concentration is also about 1500 times to 2000 times, summer fertilization do not give too high concentration, you can use 1500 times to 2000 times.

Because although the hydrangea is still growing in summer, but after all, the growth has slowed down, and the maintenance of hydrangea is very good for fertilization, generally in spring and autumn in the potting soil sprinkled with some slow-release fertilizer, the potted plant can be sprinkled on a handful, which can basically meet its growth needs for most of the year, and then supplement the water-soluble fertilizer in the later growth season, which is the easiest fertilization method.

3. Pruning in the middle of summer

When maintaining potted hydrangea, especially the large-flowered hydrangea, after August in the middle of summer, its flower condition is not good, and there is not much ornamental value to keep these flowers at this time, and these flowers can be cut off in time, so as to ensure that its new shoots can germinate quickly, which also determines that it can bloom better in the next year. If you prune too late and don't prune until autumn, you may not have flowers the next year.

4. Pay attention to spraying fungicides

The most feared thing about raising potted hydrangeas is actually anthracnose, powdery mildew and white silk disease. White silk disease is very deadly, and the whole pot of plants can only be lost after the basic infection; After infection, in addition to spraying fungicides in time, tebuconazole, bromonitrile, prochloraz or azoxystrobin, there is no good way, but also pay attention to cutting off the serious diseased leaves, which will definitely affect the growth of the plant in the later stage, and the growth of the whole plant will become very weak.

5. Prune after flowering

If you want hydrangeas to bloom more, pruning after flowering is essential. After the hydrangea is defeated, let's look down along the residual flowers of the hydrangea to find the location of the bud point, and then find a pair of sharp scissors and cut it directly! Remember to keep the remaining branches at the same height as the bud point.

This plant is not particularly light-loving and does not adapt to strong light, so be careful in the summer.

Because strong sunlight can cause the flower bulbs of this plant to fade in color and shorten their flowering period, and the plant cannot be in the dark for less than 10 hours a day, special attention should be paid to shading in the summer.

It is best to shade about 65% of the sun, so that the flowering time of this plant can be well extended.

This plant is a plant that has a very large demand for water, and the temperature in summer is relatively high, the water is absorbed relatively quickly, and the land is relatively dry in summer, so it is necessary to keep watering frequently in summer, and when watering, it is not only necessary to water the land, but also its branches and leaves should be properly watered.

In summer, hydrangeas are still in bloom, so it is also important to ensure the amount of fertilizer applied at this time to ensure that there is enough nutrients to ensure that it blooms.

1.Overall: This plant has a relatively fast growth rate in the range of 17 degrees to 27 degrees, so it is not suitable for an environment that is too cold or too hot.

2.Initial cultivation: The temperature at the beginning of cultivation is about 6 degrees. At this stage, it is mainly engaged in shoot differentiation.

3.Pre-flowering: The required temperature at this time is about 21 degrees. It is well known that increasing the temperature can speed up the flowering. Therefore, at this stage, it is necessary to increase the temperature to speed up the flowering period.

4.Flowering: Maintain a warm spring-like temperature during flowering, roughly around 15 degrees. Because flowering can only be extended if the right temperature is maintained. If the temperature is too high, the flowering period will be shortened, and if the temperature is too low, the plant may not survive.

Abstract Soil: Must be loose, water-retaining, permeable, fertile and moderately slightly acidic. Moisture:

It has a high demand for moisture and high air humidity. Light: 3 to 6 hours of light per day.

Temperature: The optimum temperature is 18 degrees to 28 degrees. Trim:

Pay special attention to the pruning time, especially for hydrangeas.

1. Soil. The cultivation of hydrangeas requires that the soil must be loose, water-retaining, permeable, fertile and moderately slightly acidic, so as to be conducive to growth.

Hydrangea. 2. Moisture.

Hydrangea has high requirements for moisture, and the surrounding air humidity is relatively high, because its leaves evaporate a lot, if the humidity is low, there is no way to ensure normal growth.

3. Light. The maintenance of hydrangeas requires bright scattered light, and it is best not to maintain them in a fully lit environment, and at the same time, it should not be a completely shaded environment. 3 to 6 hours of light per day will allow it to grow normally.

Fourth, temperature. Hydrangea hydrangea does not have high temperature requirements, and can overwinter on land normally in many parts of the country. The temperature is best kept between 18 and 28 degrees Celsius, and in winter it should not fall below 5 degrees Celsius, and around 20 degrees Celsius will promote flowering.

5. Pruning. In the maintenance of hydrangeas, special attention should be paid to the pruning time. In general, the two varieties commonly found in the market are Hydrangea grandiflora and Endless Summer. The flower buds of Endless Summer can be differentiated multiple times, so the pruning time is not very sensitive.

However, the large-flowered hydrangea must be pruned in the first half of August, followed by the time of flower bud differentiation, if the pruning lags behind to the fall of the leaves, the flower buds are actually cut off, which will reduce the number of flowers in the later stage.

When the hydrangea blooms, be careful not to expose to the sun and water more, and fertilization should also keep up, so that the flowering period can be longer.

The daily maintenance of hydrangeas should be noted: hydrangeas need to be watered, hydrangeas need to be fertilized, and hydrangeas need to be repotted.

1. Hydrangeas need to be watered

Friends who have raised hydrangeas know that it is a big bucket in the stupid hole, especially love to drink water, in spring and summer, when the temperature is high, the potting soil needs to be watered immediately as soon as it dries, if it is raised on the terrace, it is watered at least once a day in the summer, the potting soil will dry quickly, do not let it lack water for a long time, otherwise the leaves will wilt and wither.

Second, hydrangeas need to be fertilized

Hydrangea branches and leaves are luxuriant, flowering, flowering, flowering, flowering period is relatively long, so it needs more nutrients, it needs to be fertilized frequently, give more phosphorus and potassium fertilizer before flowering, and when it sprouts in spring, it also needs to give some fertilizer to promote its vigorous plants, accelerated growth, and larger and more flower buds. At the same time, it is also necessary to ensure that there is sufficient light to promote the smooth differentiation of its flower buds.

3. Hydrangeas need to be repotted

If it is a potted hydrangea, it is best to change the pot once a year, you can change the pot in spring and autumn, change the pot in spring a little earlier, to avoid affecting the flowering period, it is most suitable to change the pot and soil in autumn, and the small pot should be a larger pot, and the pot should be large enough.

The soil is fertile and loose enough to breathe and drain, and the nutrients are sufficient, so that it can grow fast enough, grow better, and have a lot of flowers, which is very beautiful. Part of the **** network, if there is something wrong, please contact to replace.

Cultivation techniques

Propagation is mainly based on cuttings, and can also be propagated by strip pressing and grafting. Cuttings in the spring or rainy season to select young mother tree on the strong shoots as cuttings, cuttings 12 20 cm long, the base of the cuttings need to be knotted, and dipped in mud, after cuttings need to be shaded, often keep moist, about 1 month to root, transplanted in the second year after survival.

In the south, it can be cultivated in the open field, while in the north, it needs to be overwintered in potted greenhouses. Transplanting should be carried out after defoliation or before germination, and the plants should be soiled. Extensive management, the main branches are easy to germinate long branches, and proper pruning is needed after flowering to shape the tree. Proper watering, top dressing, flowering and flourishing every year.
