Briefly about panicle hydrangeas
Panicle hydrangea is a large perennial shrub native to East Asia. In natural conditions, it grows like a 10-meter tree, and cultivated and planted in gardens or city parks reaches a height of no more than 3 meters.
The root system, when it grows, becomes much larger than the crown in size. They are close to the surface of the earth, which makes it impossible to get moisture from the depths of the soil. The leaves are large in size, oval in shape and painted in bright green colors. Large inflorescences are similar in shape to panicles, which consist of two types of flowers. Those that are small in size bear fruit, they fall off very quickly, but form seeds in small capsules. Those that are large are sterile. They are located above small flowers and hold tightly and for a long time on elongated stalks. Their petals are slightly inclined towards the center of the flower.
Interesting to knowthat from treelike, large-leaved, petiolate, paniculate, serrate and curly hydrangea excellent honey plants are obtained.

The Great Star great star panicle hydrangea needs the right place to grow it.The best option would be a slightly shaded area where the sun's rays do not touch the bushes in the middle of the day. In open sunny areas, the plant will feel less comfortable, and its flowers will become smaller.
It is important to know that dolomite flour, wood ash, chalk and lime cannot be added to the soil where hydrangea grows. The acidity of the soil should be at pH6.0
For the Great Star hydrangea variety, in order for it to develop well and bloom profusely, fertile, loamy, well-drained soil is suitable.
If the land on the site does not meet the requirements, then you can saturate it with the necessary elements yourself. This will require humus, peat, garden soil and sand. All of these ingredients are mixed in equal parts. In the case of clay soil, peat and sand must be added there. Before planting, 20 grams of urea, 30 grams of potassium sulfate and 150 grams of phosphate are added to the soil mixture. You can acidify the soil with henna.
When preparing planting holes, it is important to remember about the size of an adult plant and a wide root system, so they should not be made close. The distances depend on what role Great Star will play in the garden, it is planned to use it as a hedge, a free-standing plant or in flower beds.
The hole should be 50 centimeters wide and the depth should match the root system. During planting, it is important to monitor the root collar, it should remain at ground level.

You can propagate the Great Star hydrangea by layering, cuttings and seeds.
The first option is the simplest, it is enough to choose the healthiest and strongest shoot and gently bend it to the ground. Then he is pinned with the ground and fixed with the help of some kind of load or pinned with a wire. After it is regularly watered and fed. These procedures can be carried out in conjunction with the mother plant. By the next seasons, the cuttings will take root and can be separated and transplanted to a previously prepared area.
If it is customary to grow Great Star hydrangeas using cuttings, then this can be done from spring to autumn, as the gardener wants.
Carrying out this procedure in the spring, it is necessary to cut off cuttings from last year's lignified shoots, when the buds begin to swell.
The presence of two internodes on the handle is a must. The stalk is cut at an acute angle, the top must remain flat.
Then the cuttings are dipped for several hours in preparations that stimulate root formation and are planted in a container with a previously prepared soil mixture from torus and sand to a depth of 5 centimeters. In order for the plant to take root well, it must be watered and placed in greenhouse conditions. After 30 days, the young seedling will take root and can be planted in the garden. Plants of the first year of life require protection for the period of winter cold.
It is important to remember that the shoots of the first year of life are not suitable for cuttings.
The seed method of propagation of panicle hydrangea is only suitable for planting at home. To grow the bushes in this way will take a lot of effort, time and patience. This is probably why this method is not popular among gardeners. It is also important to know that shrubs rarely grow from seeds that look like the mother plant.
Before sowing, you need to prepare a soil mixture, it should include sand, peat and soil. The seeds do not need to be buried, they must be scattered over the surface and lightly sprinkled with earth. After that, the container is covered with plastic wrap and removed to a place where the air temperature will not drop below 17 degrees. The film must be lifted periodically, allowing the plants to breathe.
The first shoots can be seen in 4 weeks.As soon as the first leaves appear, a pick is carried out during which only strong seedlings are selected and they are transplanted in separate containers.
Nitrogen-based fertilizers can sometimes be added as they grow.
Transplantation of Great Star panicle hydrangeas into the garden begins only two years later, but before that they must undergo a hardening procedure. To do this, it is necessary to take the containers outside and increase the time spent there every day.

The first top dressing is applied at the beginning of spring, it is carried out with the help of nitrogen fertilizers, which are responsible for building up the green mass of the plant. Fertilizers can be made independently from phosphate and ammonium sulfate, in proportions of 30g. x 40 gr. per bush, or purchase the mixture from a specialty store or nursery and follow the directions in the instructions.
Zircon will be able to provide good support to the bushes if the foliage is treated with it throughout the season. It is used dissolved.
The next feeding is carried out during the period of bud formation. Potassium sulfate-40 gr is suitable here. and phosphate - 60 gr. Herbal infusions where nettle and dandelion are used are also well suited.
In summer and autumn, plants are fed with organic fertilizers such as manure, humus or compost. The humanism of potassium is also well suited in this case.

Hydrangea Great Star: pruning a variety
Pruning Great Star hydrangeas is done in early spring and mid-fall. During the autumn pruning of the Great Star hydrangea, all inflorescences that have faded are removed. Spring is carried out before the start of sap flow, and at this moment you can not only remove unnecessary branches, but also give the bush the shape of a tree.
Bushes younger than two years old are not pruned. In these years, you can decide what shape your bush should have.
If the natural form is left, then in the spring all branches that have damage, signs of disease, dried out or improperly growing are removed. Annual shoots are also pruned, but only up to 5 buds.
If a decision is made to form a Great Star hydrangea bush like a tree, then an even young shoot should be chosen. It is planted in a separate place and the trunk is formed over the course of three years. To do this, you need to pinch all the lateral shoots, which are cut into the ring in a year. This plant needs support, so you need to set a peg next to it and tie a hydrangea to it. Every year, the central trunk is shortened to a well-formed healthy bud, and this must be done until the tree grows to one and a half meters.Then you can begin to form the crown and skeletal branches. The tree will take 8 years to form. The Great Star panicle hydrangea is easy to form, as the best can do it.

Diseases and pests: control methods
Hydrangea paniculata Great Star has a strong immunity, but a small amount of vitamins and trace elements, stagnation of water in the soil, frequent drought, changing to a sharp increase in moisture, violation of the rules of pruning, planting and care, can cause the development of fungal and viral diseases.
The most common disease of the Great Star hydrangea is chlorosis. It develops due to a lack of iron and other useful elements. When the disease comes, the rich green color of the leaves becomes pale and gradually they turn yellow. At the initial stage of the disease, it is necessary to spray the bush with preparations containing a complex of minerals. If the disease is started, then copper sulfate should be added to the soil.
In addition to chlorosis, you can face such diseases as:
White rot is a fungal disease that affects the root system, and later branches and leaves. You can recognize the disease by brown spots on foliage and branches. Phytosporin will help to cope with it. If the disease has an advanced form, then the plant is dug up and burned.
Gray rot is another fungal disease that affects the living tissue of the bush. It can be determined by the holes in the leaves and by their lethargy and wateriness. This disease can quickly affect all the plants in the garden, especially if it is rainy weather. Therefore, if detected, it is necessary to immediately treat the bush with fungicides, and cut off and burn the damaged areas.
Powdery mildew is a fungal disease that can be triggered by a humid environment. You can identify it by the white oily spots that cover the leaves. If the disease has not yet started, then a solution must be made and the plant must be treated. For this, copper sulfate, laundry soap and water are mixed. If this is not enough, then a systemic fungicide should be used for treatment.
It is far from always possible to detect the disease at its initial stage, so it is worth taking preventive measures and treating the bushes with the help of fungicides and copper sulfate.
Hydrangea Great Star can be affected by snails, slugs, aphids, spider mites, rootworms. It is necessary to fight with them throughout the season.
If the plant has undergone an invasion of snails, they must be removed as soon as possible. This is done by hand, and also special preparations are laid out next to the bushes in order to destroy those that are hidden at the roots. These insects harm buds and leaves, so if found, you should act immediately.
Aphids suck the juices out of the plant. She settles on the inside of the sheet. Insecticides will help to cope with this pest.
The appearance of a spider mite on a bush can be recognized by a thin cobweb on the lower part of the leaf, which later die. Insecticidal preparations can help cope with it.
Gall nematode cannot be detected immediately. If it appears, the plant will have to be destroyed, since it will not be possible to get rid of the pest. It attacks the roots and the bush dies.
As a preventive measure, treatment with a bush using copper sulfate is carried out.
