Peculiarities
Blue hydrangea is a garden shrub of the hydrangea family, which is a huge green bushes with spherical blue inflorescences.

How to plant
In order for the plant to bloom well and not hurt, planting it requires special attention. It is necessary to choose the right time of the year - spring or autumn. In the spring, it is planted immediately after the snow melts into the warm ground. Spring planting will have a good effect on the root system and will allow you to get accustomed to the onset of cold weather. If the autumn is warm, then planting can begin in September, which will allow the hydrangea to grow stronger before the first frost. Open ground must be prepared: well drained and properly moistened . It should contain a lot of humus: 1 to 1 with earth, with the addition of sand and peat chips.
Choose a place without direct rays of the sun, you can half-shaded - it all depends on the variety. When all these measures are followed, you can prepare for planting. The hole should be 45 cm deep, width - depending on the size of the roots.
If the gardener wants a lush flowering, then it is necessary to plant in a row with a distance between the bushes of 60–70 cm, in a dug trench.
How to properly care
Top dressing begins already with planting a plant. You can fertilize it with a mixture of potassium sulphide and superphosphate. In principle, in order for flowering to last longer, fertilizers should be applied little by little throughout the flowering season.
As for watering, it should be abundant, but without stagnant moisture . If there is not enough liquid, the plant will begin to dry out. You can water it 2 or 3 times a week, depending on the weather. The infection needs to be poured about 2 buckets per bush. The correct acidic environment in the soil will provide a beautiful blue color.
Growing indoors
Home hydrangea is more modest in size, but with good care it can reach a height of up to 1 m. It is not at all difficult to grow and care for it, but it is necessary to adhere to some rules.
This plant is very moisture-loving and should not be allowed to dry for a long time . In the summer, it is better to identify it in partial shade, but when the formation of buds begins, it is necessary to put the flower on a well-lit window, but without direct sunlight. The optimum air temperature should be + 18-23 degrees, the hydrangea does not like higher temperatures - leaves can fall off profusely. Does not tolerate drafts and sudden temperature changes. You can spray the leaves without restrictions or place a container of water next to the plant. In winter, it is in hibernation, so you need to water it so that the soil does not dry out. With the appearance of the first leaves in the spring, abundant watering is resumed.
Top dressing begins at the first budding 2 times a month.
Reproduction methods
Cuttings . With this choice of propagation, a correctly chosen cutting for cutting plays an important role. A stalk is a stem without leaves with 2 or 3 buds. It is better to cut them in the morning after watering. For this, the side parts from a young bush are suitable. The cut shoot must be placed in water in a dark place. After that, cut off the crown, shorten to the third kidney and place in any root stimulating agent. Next, you can plant the cuttings by covering them with jars. You can water directly on them. After about a month, the leaves will appear, so the jars can be removed.
By dividing the bush . This method of reproduction is used when they want to transplant the inflorescence to another place. Before digging, it must be well poured. Chip off the soil from the roots and carefully divide the root system into roots of any size. Any such part can be safely planted as an independent plant in the place you need.
Layers . The fastest and easiest way to reproduce. To do this, you need to take a side branch and dig it into the ground to a shallow depth, fix it. In August, new shoots should appear on them. In October, they can be separated from the main bush and dug into the ground for the winter. In spring, plant for growing. After a year, the teenager is ready for a permanent place of growth.
Seeds . A very long and painstaking method that is not popular. Most hydrangea varieties are hybrid, and this method is not suitable for them. But if you have the patience to plant seedlings and grow them for a couple of years, then this method is for you. Spread the seeds over wet soil, press in and cover with foil or glass. Be sure to ventilate and drain off condensation.
The first shoots will appear in 3 weeks. You will have to wait 2 years until they reach a height of 30–40 cm.
Offspring . Small shoots grow near the main bush. They must be carefully dug up and planted in a separate bed for growing, and after strengthening, they can be planted in a new place.
Diseases and pests
Improper care of the shrub can lead to some diseases and provoke the appearance of pests. If you do not take any action to eliminate the signs, the hydrangea may die.
- Young shoots are covered with brown spots, which means that gray rot has appeared. Without disinfection, the inflorescence will be covered with a gray bloom and die. To do this, you need to cut off the affected flowers, treat the bush with "Fundazol" or "Rovral", ensure normal watering and ventilation.
- Powdery mildew - a fungal disease that appears due to the abundant humidity in the air, affects the entire bush and does not allow it to grow further, it withers and dies. Infected shoots and flowers must be pruned and treated with a fungicide.
- With an excess of humus or lime in the ground, hydrangea greens can lose their color and become pale. This disease is called chlorosis. You can get rid of it by treating the shrub with copper sulfate or potassium nitrate.
- Hydrangea is a plant with strong immunity, but it can also be overcome by pests. This is the aphid. The disinfectant can be applied once a week until the pest is gone.
- Spider mite. It is indicated by the appearance of small yellow spots, from which a marble pattern is formed. If the temperature and humidity outside are high, then the greens will be wrapped in cobwebs in a week, will begin to dry out and fall. At the first sign of a tick, it is necessary to treat the plant with soapy water. If the pest has developed strongly, then the treatment must be carried out with stronger insecticides.
- Slugs. They are favorably bred in dense thickets of hydrangea, eat leaves. You can destroy them by spreading the granular preparation "Molluscicide" on the soil.
- Rust - seen by a rusty coating on the foliage. The disease can appear due to a strong density or a large concentration of nitrogen in the soil. It can be treated by spraying with copper chloride.
- The most dangerous and incurable disease is ring spot. It can be identified by round spots with a diameter of 2 cm. The foliage wrinkles and falls off, the buds become loose and die. As a result, the shrub will not be able to plant its flowering, or it will be small and inconspicuous.
