Hydrangea cultivation method

1. Light: When cultivating hydrangeas, they should be placed in a shady environment to avoid strong light burning the buds and affecting the aesthetics. 2. Temperature:

The breeding temperature is kept between 18-28 degrees, and it should not be lower than 5 degrees in winter. 3. Water: Water hydrangeas every day in spring and morning and evening in summer.

4. Fertilization: spray potassium dihydrogen phosphate for hydrangea during flowering period.

1. Lighting conditions

Hydrangea is a shaded flower plant species, try to put it in a ventilated and cool place, and accept the moderate intensity of warmer scattered light, the light is too strong, which will affect the ornamental nature of the flower. However, in winter, the light is weak, so you can move to a slightly more sunny area.

2. Temperature range

18 28 is the suitable growth range for hydrangeas, and if the temperature is too high, the growth functions of hydrangeas will be hindered and stunted. If the growth temperature is low, then the whole plant is at risk of frostbite and needs to be stable at more than 5 in winter.

3. Water irrigation

Hydrangeas should be kept moist in the potting soil in spring and summer, and watered frequently, once a day or once in the morning and once in the evening. During the growing season, the potting soil should not be too dry, and in the winter, the water irrigation should be reduced. In the hot environment, the leaves can be sprayed with water mist to increase humidity.

4. Fertilizer topdressing

Hydrangea at the peak of growth is very fertilizer-loving, every 15 20 days to the plant to apply a diluted cake fertilizer water, in the flowering period can choose potassium dihydrogen phosphate or superphosphate solution irrigation, fertilizer applied in time, sufficient, the flowers are larger, the color is more vivid.

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.

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.

The volume of hydrangea is relatively large, so when choosing a flower pot, we should choose a slightly larger pot, for example, we can use a larger pot between 25 and 35 cm, so that the hydrangea root system has enough space to grow, its growth will be more lush, and the flowers will bloom luxuriantly.

When choosing soil, you can choose loose and fertile soil that is both draining and retaining water, so you can use peat and perlite mixed to prepare it as a substrate for cultivation at home, or you can use humus, garden soil, and river sand to mix it in a ratio of 3:2:1 for cultivation.

Hydrangeas are short-day flowers, so it is necessary to avoid full-day cultivation during the maintenance period, and the daily light time is 3 to 6 hours.

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 has a high requirement for moisture, and the surrounding air humidity is relatively high, because the evaporation of the leaves of other lines is large, and if the humidity is low, there is no way to ensure normal growth.

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. Ensuring 3 to 6 hours of light per day can maintain its normal growth.

Hydrangeas do not have high temperature requirements, and they 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.

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 the defoliation is actually cut off, it will reduce the number of flowering in the later stage.

Hydrangea cultivation method

1. Soil. Hydrangea needs to use soil with high nutrient content and strong air permeability, which can be prepared by mixing humus, garden soil, river sand and cake fertilizer in the ratio of 4:3:2:1, or mixing humus, sand and cake fertilizer in the ratio of 6:3:1.

2. Illumination. Hydrangeas like yin rather than yang. In spring, it is best to move to an outdoor semi-shaded place for maintenance, summer can need an appropriate amount of shade, autumn light is fading, it should be placed in a bright place, can promote flower bud differentiation, winter can be placed in the indoor sunny place.

3. Moisture. Hydrangeas like moisture but are afraid of waterlogging, so they should be watered often but not too much at once. Water more in spring and summer, reduce it in the fall, and reduce it again in winter.

Fourth, temperature. The most suitable growth temperature for hydrangeas is 18-28, and in winter, pay attention to keeping warm and raise the temperature to more than 5 to prevent it from being frostbitten.

5. Precautions.

Acidic soils. In addition to normal watering, you can also add one or two drops of unsalted vinegar to the water, which can reduce the pH value of the soil, so that hydrangeas grow better. Trim in time.

During its growth period, topping should be carried out to promote the growth of side branches, and it should be cut short before winter, which is more conducive to winter.

The hydrangea maintenance method is as follows:1. Light: Prefer warm, humid and semi-shady environments.

The growth temperature of hydrangea is 18-28. Flower bud differentiation takes 6-8 weeks under 5-7 conditions, 20 temperature can promote flowering, and maintain 16 after flowering, which can prolong the flowering period. But the high temperature makes the flowers fade quickly.

2. Watering: Hydrangea potting soil should be kept moist, but watering should not be too much, especially in the rainy season, to pay attention to drainage to prevent root rot caused by waterlogging.

3. Soil: The soil is loose, fertile and well-drained sandy loam.

Hydrangea cultivation methods are:

1. Light: hydrangea is shade-tolerant and not light-resistant. Usually let it be exposed to astigmatism occasionally. If it is left in direct light for a long time, it is easy to get sunburned. Pay special attention to the bright light in summer. In winter, the light is weak, so you can bask in more sun.

2. Temperature: Hydrangea likes a warm environment, the temperature is best between 18 and 28, and its growth will be more vigorous. If the temperature is too high, its growth will be inhibited, and the temperature is too low to be frostbitten, so temperature control measures should be taken in summer and winter.

3. Watering: Hydrangeas like a moist soil environment, and if they find that the soil is dry, they should be watered and moisturized. However, the amount of water needs to be controlled, and it is strictly forbidden to accumulate water. Usually water more in spring and summer, once every two or three days. In autumn and winter, water should be properly controlled, and no drying or watering.

4. Fertilization: It likes fertilizer very much, and it is necessary to top dressing once every half a month in the peak growth season, just use diluted cake fertilizer water. Potassium dihydrogen phosphate fertilizer should also be applied during the flowering period to promote better flowering.

Many people have heard that hydrangea is a semi-shade tolerant plant (not a half-shade preference), and it does not like to keep it in semi-shade for a long time. Only when the temperature is excessively hot, such as in summer, when the temperature exceeds 35 degrees, proper shade is required at noon and in the afternoon.

In addition, it is actually because it is raised indoors, whether it is on the south-facing or east-facing balcony, whether there is sufficient sunlight, and the ventilation of the environment is not as good as outdoors.

Planting hydrangea must be matched with the appropriate potting soil, in the soil must be more thoughtful, some friends' potted hydrangea leaves are easy to scorch, the tips and edges of the leaves are easy to dry and rot, it is likely to be caused by the soil is not breathable.

Notes:

The potted hydrangea was originally planted with vegetable garden soil, and the topsoil can be washed off with clean water (or directly removed) until the root system is exposed, and then new soil can be added and planted in a pot that is one size larger than before.

To grow potted hydrangeas, you can use the common green mountain pots or gallon pots. If you use gallon pots for cultivation, you can drill a few more holes in the side of the pot to increase air permeability, and you can even dig a few vertical openings directly on the side of the pot to increase drainage and air permeability.
