Archaeological excavations carried out indicate that hydrangea appeared in ancient times. Kuichi, as it is often called in most countries of the world, is also called Japanese. But where the plant comes from, it is called Kyushu Ajisay.

Hydrangea paniculata Kiushu on a trunk, as an ornamental plant, was brought to European countries at the beginning of the 18th century. It was brought from Japan thanks to the naturalist, researcher of eastern countries, physician from Germany, Philip Franz von Siebold. After a short time, the Kiushu variety, belonging to the paniculate species, began to be actively cultivated.

As adults, the bushes grow up to three meters in height. The branches are colored red-brown and brown, which are only slightly visible under the emerald green leaves. When covered with them, the plants become especially exquisite. They also get a decorative look thanks to the petioles on which the leaves hold and which have the same tone as the branches. Fragrant white flowers gather in cone-shaped panicle inflorescences and cover the entire crown of a bush with a diameter of 3 meters.
The shrub itself has a spreading fan-like shape, which makes it very effective. This bush is easy to shape, so you can give it any look.

The acquired bush will demonstrate all its features and characteristics after a few years. Then you can see all the beauty of the Kyushu hydrangea.

It is important to know that the Kyushu hydrangea bush on the trunk can begin to form from the third year of the plant's life.

When to plant

Spring is the best time to plant the Kyushu hydrangea in the garden. Planting operations can be carried out after the threat of frost has completely disappeared. Those seedlings that have a well-formed root system can be planted in early autumn.
For young seedlings, the best time is spring.

Suitable place for Hydrangea Kyushu on the trunk

Hydrangea Kyushu - hydrangea paniculata kyushu - prefers open light areas or partial shade. In direct sunlight, the plant will not feel very well, as the soil there will dry out quickly, and the hydrangea is not drought tolerant. A plot in full shade will not work either. There, the plant will not bloom or the flowers will be very faded and in small quantities.
When choosing a location, you should give preference to areas with good natural light. You can not plant bushes next to trees, since the latter have a powerful and large root system, which will take moisture and nutrients from the hydrangea. It is also important that the site is protected from strong winds that can break fragile and thin shoots of young seedlings.
Soil preparation:

The soil for the Kyushu hydrangea on the trunk is prepared two weeks before planting, so that the soil has time to sink. The planting holes should be 40 centimeters deep and 50 x 60 centimeters wide. A drainage 8 cm layer of broken brick, crushed stone or expanded clay is laid at the bottom. Next, you need to make a soil mixture of 60 gr. phosphate, 20 gr. potassium, 20 gr. nitrogen fertilizers (if planting is carried out in spring), peat, in this case it depends on the level of acidity, the higher it is, the less fertilizer, and 8 kg. humus. All ingredients must be well blended. If the soil is sandy, then a 4 cm layer of clay is added there.

It is important to know that the introduction of fresh manure and lime is prohibited. These ingredients can kill the plant.
It is also important to remember that the hole must match the size of the root system.

Hydrangea Kiushu: pruning and planting varieties

When preparing the holes, it is necessary to leave a distance of one and a half meters between them, if it is planned to create a hedge from them, then 80 centimeters will be enough, but subject to thinning pruning once a season. This will prevent the plants from drowning out each other.
For standard forms, it is necessary to leave two meters.
Before planting, it is necessary to prune the roots of the seedling, this will serve as an incentive for more active growth. During spring planting, it is necessary to shorten the shoots of the first year of life to 4 buds.
When planting, it is important that the root collar extends no more than 2 centimeters deep into the ground. As soon as the plant is watered abundantly, the neck will come to the surface. After planting, apply an 8 cm layer of mulch to the trunk circle. For this, you can use peat, wood chips, pine needles or straw.

Reproduction of hydrangea paniculata Kiushu on a trunk can be carried out in different ways:

• The first way is to plant seeds. To do this, mix leafy soil, peat and sand in a ratio of 4/2/1, place in a shallow container, sow the seeds without burying them and lightly sprinkle with earth. After that, it is necessary to moisten the soil by spraying from a spray bottle and cover with a transparent film to create greenhouse conditions. Watering should be done regularly without allowing the soil to dry out. After 30 days, it will be possible to observe the first shoots and remove the film.
  As soon as the cotyledon leaves appear, a pick is carried out.As soon as the fourth leaf appears on the seedlings, a re-pick is carried out, in separate small pots. Tempering can now be carried out. In order for this procedure to be safe for seedlings, they must be exposed outside during the daytime and in places where direct sunlight and drafts will not touch them. The time spent in the garden increases daily. Before planting in the garden, the plant should be at home for 2 years, and with the onset of spring, they are transplanted to a prepared area where they will grow and grow stronger. Planting is carried out after the soil has warmed up. As soon as the seedling reaches the age of four, it can be transplanted into a permanent place of residence. Paniculate hydrangeas are not tolerant of frequent transplants.
• The second way is with cuttings. This will require young shoots on which there are several developed buds. They are placed in a growth stimulant solution until the roots appear, and then transplanted into a container. If you plan to plant the cuttings directly into the open ground, then it is necessary to remove the lower leaves completely, and the upper ones by 1/2, this will facilitate photosynthesis. Having planted the stalk, it must be covered to create a greenhouse effect. After rooting, the cutting can be opened. It is necessary to regularly air and water the seedling.
• The third method of propagation - layering Given the fragility and sensitivity of Kyushu roots to any damage, all procedures associated with reproduction should be carried out with caution. Loosening of the bush, which will serve as a mother plant, is carried out in the spring. After that, a deepening is made, the width of which will be 5 centimeters. Before the buds begin to bloom, you need to bend one shoot to this hole, sprinkle it with soil and put a load that will hold the branch.
  The top of the branch remains above the ground and tied to a support to create a vertical position. When the vertical side shoots reach 20 centimeters, it is necessary to spud the plant. It is necessary to sprinkle and water regularly. In the fall, the shoots will give roots and they can be separated from the bush and planted in a growing area.

Diseases and pests: control methods

Kyushu has good immunity and, if grown properly, will not hurt or suffer from pests. The main thing here will be preventive actions:
Humus in the soil in large quantities and lime will lead to chlorosis, due to which the leaves turn yellow, so this should not be allowed. If the plant is sick, then potassium nitrate and ferrous sulfate will be needed to combat it.The drugs must be used in accordance with the instructions in the instructions.
High humidity should not be allowed, as this may cause powdery mildew, a fungal disease. It manifests itself in the form of dark spots on the leaves. For the fight, a solution is used made of copper sulfate, green soap and water in proportions of 15 grams. x 150 gr. x 10 l.
If there is too little moisture, spider mites and aphids may appear. To cope with these pests will help preparations based on insecticides, as well as laundry soap dissolved in water.

Kiushu can be grown not only in private gardens or city parks, but also in areas with high gas content and smoke. Therefore, it can decorate parks of factories or roadsides along highways.
