Planting is an important component in the further duration of the plant. Its type, condition, fertility, and many other aspects depend on this. Nikko Bleu cannot stand the windy terrain. Its structure itself is not adapted to the wind: shoots are delicate and fragile, they can bend and spoil their appearance. Planting shrubs is recommended in weakly sunny places, but not completely shaded. In winter, the plant should be sheltered, because it does not withstand low temperatures.
The choice of location, as well as planting, is an important aspect in the cultivation of ornamental crops. For planting Nikko, places with fertile, humus soil and low neutral acidity are suitable. Hydrangea is quite tender and does not withstand the wind, planting should be carried out at the fence or any other support that prevents breakage of the shoots.
Plant hydrangea, preferably in the late spring or autumn, but preferably until October. The size of the planting pit is recommended to be selected depending on the volume of the roots of the seedling. Before planting, you should fill the pit with a mixture of fertilizers and earth, namely with the addition of peat, humus and needles in a ratio of 2: 2: 1: 1.
Did you know? In the city of Hirata (Japan), a garden center "Jupia Land Hirata" was created, which was listed in the Guinness Book of Records for the largest number of hydrangeas in the world. Judges and experts studied all varieties of flowers planted in the park for more than 5 hours and counted 372 species.
The composition of the soil may indicate the amount of drainage in the pit, when there is a lot of clay in the soil and it is very dense, then drainage should not be spared. This contributes to the long life of the plant. So, the water does not stagnate, and the roots do not rot. Before planting, it is recommended to soak the rhizome in clean water.
When planting hydrangeas, it is recommended to follow a certain algorithm of actions:
- Put the prepared seedling in a previously dug hole.
- Sprinkle the roots with clean soil.
- The roots should be deepened, leaving shoot-giving buds on the surface.
- Sprinkle the seedling with earth and compact it.
- After planting, it is necessary to water the seedling so that it quickly adapts and takes root.
- On the ground surface, mulch with dry peat, sawdust and needles - this protects against drying out and perfectly nourishes the soil.
Proper care of hydrangea will prevent its death and provide beautiful flowering. From how correctly agrotechnical measures will be carried out, first of all, the appearance of the flower depends. For each variety, you can choose a fertilizer that will improve the condition and if pests or diseases are present on the seedling, then this is the sure way to victory.
Hydrangea - a flower is quite hygrophilous, so you need to water it abundantly. Breeders are advised to carry out watering from spring to late autumn. Autumn watering does not allow the roots to freeze in the winter. Watch the moisture of the flowerbed, but do not flood. Hydrangea has a delicate root system that reacts sharply to excess moisture and can rot.
For the normal life of the bush, its successful development, do not forget about its nutrition in the form of fertilizers, in the maximum permissible norms. With the onset of spring, when the leaves begin to appear, it is recommended that hydrangea be fed. Initially, nitrogen must be added to the ground, which accelerates the rate of formation of the crown of the bush. Before starting to open the kidneys of hydrangea Nikko Bleu, it is fertilized again, using potassium-phosphorus compounds.
Loosening and mulching of the earth
Loosening and mulching are some of the important methods used in horticulture, because by their actions they help preserve the vital activity of plants for a long time. Mulching is a very useful process, during which the further problems of the existence of a plant variety are eliminated. Its effectiveness helps to improve the mechanical and biochemical qualities of the soil, and also provides the most favorable and normal conditions for the continued growth and development of hydrangea.
Important! The color of hydrangea can be changed with fertilizer. If aluminum sulfate and sulfur are added to the soil under the root, then pink and blue inflorescences will appear simultaneously on the plant.
After adaptation of the flower and plentiful watering, a basal circle is made around, which is recommended to mulch. So, the moisture will last longer, while the roots do not rot. The next thing to do is to loosen the ground, providing air exchange to the roots and making the soil more penetrating.
Trimming and Shaping
Pruning forms a beautiful, neat bush from an overgrown and obsolete bush, with a compact and collected crown. This will help in the further development of hydrangea. It is necessary to get rid of excess, and since the flower has last year's shoots on which buds may appear, it is necessary to trim old branches. But be careful, because buds may appear at the ends of shoots.
In spring, it is recommended to shorten the shoots by a couple of buds, and weak ones are removed. There are branches that are growing rapidly inside the bush, they should also be removed to the base, although they are healthy. With their growth, they spoil the shape of the bush. After the first year of hydrangea flowering, pruning should be done. It is recommended to shorten very long branches, trim old and damaged ones. The next year, the plant is cut to the lowest growths. If necessary, thin out the bush, removing obsolete branches.
Winter hardiness and shelter for the winter

To protect the root system, at the base of the flower, it is recommended that the soil be covered with a large layer of peat. If the shoots are too long, they need to be laid on the soil and secured, overlaid with old leaves. In the spring, with the onset of heat, the bush is “deployed” because excess moisture adversely affects the condition of the roots and the plant itself.
Transplanting Nikko Blue, you need to study some aspects. Transplantation can be carried out in spring and autumn. In the spring - before the start of sap flow, in the fall - after the buds open. During flowering, gardeners do not recommend transplanting it, this can harm the appearance. More often, the plant is transplanted in the fall, in mid-September, t. This is the most optimal time. At this point, flowering ends, the air temperature is suitable and the roots themselves did not have time to take root. The main aspect of transplantation is the transplant with an earthen lump. Try not to damage the roots.
