How do you raise 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.

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.

Maintenance characteristics: although it likes water, the indoor ventilation is not good, the evaporation is slow, and the roots are easy to stuffy, so it is necessary to wait for the topsoil to dry before watering. In summer, I am most afraid of high temperature + high humidity, so it is better to hang my head and then soak the pot, than to waterlog.

Blue: ferrous sulfate + aluminum sulfate dilute 2000 times to irrigate the roots, once a week.

Symptoms of stuffy roots: the flower buds are charred black, the petals are scorched, the leaf tips and edges are dry and blackened or dark green, but the potting soil is moist.

Symptoms of dehydration: yellow sunburn (sunburn), flowers hanging down.

Online shopping for hydrangea] first put it in a cool and ventilated place for 2-3 days, change the pot, water thoroughly, and then put it in a cool and ventilated place for a week.

5 13 is basically stable and no longer continues to scorch, the surface of the potting soil 2 knuckles are dry, watered.

5 10 sunny + windy, ventilated place, continue to control water.

5 9 shaded, ventilated placed. Most of the flower buds wilted, and only one bud was kept in the end, and the rest of the pruned, budd branch cuttings (new and old branches blooming in endless summer are not afraid of cutting).

5 6 shade, because the root system is severely damaged, the petals continue to scorch, watering the roots (ready not to see the flowers).

5 5 sunny, not getting better, in the afternoon planing out to dry the roots, a little pick up some soil, change the small pot at night to replant, the soil is also dry for most of the day, and add the deer swamp soil into to increase the air permeability (the original soil has more loose scales, it is estimated that it is too water-retaining), the soil is still wet, only a little hb101 water, but the next morning there is still water in the tray, quickly pour it out.

5 4 shade, the buds are scorched black, start emergency treatment: tilt the pot, loosen the soil on the surface, poke holes, and dry in a cool and ventilated place.

4 29 found that some leaf tips and edges were scorched, and asked customer service to say that the water was not ventilated, and the balcony windows have been wide open since then.

Maintenance records

3 28 Endless Summer、Flower Temari to the home。

Endless Summer: 1 gallon with flower buds, but lack of water hangs down, soak the pot for 2 hours, and recover after 2 days. The leaves under the bottom are curly, and the customer service is caused by a large temperature difference, so it doesn't matter.

Flower temari: normal, no flower buds.

3 29 foliar sprays of potassium dihydrogen phosphate.

4 5 dozen flower buds.

Summary of issues

1.How long does it take to get home and change pots? How many gallons is appropriate? How soon after arriving home can I start using the nutrient solution?

After receiving it, the seedlings are slowed first. Slow seedlings are placed in a cool and ventilated place. Where it doesn't rain.

You see if the potting soil is dry. If the soil is dry, water thoroughly. After 3-5 days of slow seedling, you can change to a terracotta pot or plastic pot with a large diameter of about 5-10cm and good air permeability.

Repotting: Whether you need to change the pot should see whether the root is full, whether the root grows at the bottom of the pot, if the root has been full and has grown out of the bottom of the pot, you need to change a pot 5cm larger than the original diameter, avoid small seedlings for large pots.

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.

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 of hydrangeas, and if the temperature is too high, the growth functions of hydrangea 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.

Choose the right fertilizer

We are also particular about applying fertilizer to the embroidered forest balls. First of all, we must determine what elements it is missing, and then we need to prescribe the right medicine and what kind of yuan ruler Xun Su to supplement it, only then can we choose the right fertilizer. For example, phosphorus and potassium fertilizers can supplement phosphorus and potassium, and nitrogen fertilizers can supplement nitrogen.

What kind of elements it lacks will behave differently, so when we breed hydrangeas, we must observe it carefully. If it is in the period of vigorous growth, we can apply some liquid fertilizer to it, which will help it to produce large and beautiful flowers.

Hydrangea cultivation methods: soil, light, watering, fertilization.

1. Soil: Hydrangea does not have strict requirements for soil, and generally uses loose and fertile sandy loam soil to ensure good ventilation and drainage performance, and basically there will be no problems. It can be mixed with 4 parts of humus, 3 parts of garden soil, 2 parts of river sand and 1 part of cake fertilizer, or mixed with 6 parts of humus, 3 parts of furnace roll polity residue and 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.

2. Light: Hydrangea is a flowering plant that is illuminated in a short day, and can receive bright direct light every day, and can not grow in a shady place for a long time, avoiding the scorching sun in summer, and probably shading 60 70 is the best.

3. Watering: In the spring and autumn season, the growth is fast, the water demand increases, and it is necessary to water once every 2 3 days. In summer, the high temperature and the rapid evaporation of the lack of water need 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.

4. Fertilization: When planting or repotting, slow-release fertilizer, organic fertilizer or bone meal can be applied as 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.

Precautions for hydrangeas

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 and fertilizer rotting, and in serious cases, it will lead to the death of plants. 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, the water will remain on the leaves or flowers for a long time, and there may be rotten leaves and flowers.

3. The whole plant of hydrangea is toxic, and attention needs to be paid in the maintenance process.

The cultivation method of hydrangea is as follows:

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.

Precautions

If you want hydrangeas to bloom as scheduled, you need to top fertilize them during the maintenance period.

Before flowering, dilute phosphorus and potassium fertilizer should be applied and sprayed directly on the foliage to promote better flowering. After flowering, compound fertilizer is applied again to replenish the nutrients consumed.
