The flower grower must understand that hydrangea is a very whimsical plant. Therefore, when deciding to plant it in the garden, it is necessary to approach the choice of a place for planting and its preparation with special scrupulousness. It is important to choose and prepare planting material correctly. About when to plant hydrangea and how to plant it in open ground, read on.
Planting in open ground is carried out in the spring with the onset of stable warm weather at + 15 ° C. The procedure is carried out from mid-April to mid-May. Autumn landing is carried out from mid-September to the end of October.
Important! The gardener must independently focus on weather conditions, if less than 3 weeks remain before the start of the autumn-winter frosts, then the planting process should be postponed until next year.
For hydrangea, you need to choose a well-lit or semi-shaded area. The bush loves moisture, so it should not be planted next to large trees that will absorb it. Also, when choosing a site, you should pay attention to drafts, if any, it is better to look for another place for planting, because harmful insects and spores of fungi quickly spread in the wind.
The soil for hydrangea should be loose and moisture permeable. The plant will develop well on loamy and fertile soils with acidic pH.
Soil and seedling preparation
Seedlings should be purchased only in special nurseries or stores.who have proven themselves in the field of floriculture. Also, planting material can be grown independently, which will be written in the article below.
When choosing a seedling in the nursery, you need to choose only those plants that do not contain traces of diaper rash, have from 3 to 5 well-developed branches. The root neck should not be over-dried or moldy.
When planting hydrangeas, it is necessary to prepare the soil in advance on the site. To do this, six months before the spring planting or a month before the autumn planting, they dig the soil onto the bayonet of a shovel, 10 kg of sand, 10 kg of peat and 5 kg of humus for every 1 m² are put into the soil.
Did you know? According to one version, the name Hydrangea was given to hydrangea for its hydrophilicity, because it comes from Greek words «hydor»that translates as water and «aggeion» — vessel.
The planting process begins with digging a hole. It should be 40 cm deep and 40 cm wide.
The top layer of soil from the dug hole is left to prepare a nutrient substrate, which consists of:
- soil 10 kg;
- peat 5 kg;
- sand 5 kg;
- superphosphate 30 g
- Pour a 5 cm drainage layer of pebbles into the hole.
- Then, pour the prepared substrate to the middle of the pit and form a mound in the form of a hill.
- Insert the seedling into the hole.
- Add soil substrate to the top of the pit and compact.
- Water the plant with 10 liters of water, mulch the soil near the trunk with peat, a layer of 5 cm.
With proper care of the crop, you can easily grow a healthy, beautiful hydrangea bush that will delight the eye. The rules of care, first of all, are timely watering and feeding.
There is also a need for sanitary and anti-aging pruning, which are necessary for the plant to develop properly and better flowering. To care for hydrangea is necessary not only in the summer, but also to carry out autumn preparations for winter. How to take care of the plant, as well as how to form a shtamb stamb, read on.
Hydrangea is demanding on hydration. Lack of moisture, for this plant is fraught with the appearance of a disease called "chlorosis", which develops due to lack of watering. Irrigation is carried out once a week in dry weather or as the earthen coma dries out in rainy weather.
Irrigation requires 20 liters of water per adult bush and 10 on young plants up to 4 years old. So that a dense crust does not form on the soil near the trunk after irrigation, a loosening procedure should be carried out, 2-3 cm deep.
The plant needs 3 top dressings per season. They begin to make upon reaching the bush 3 years of age. Until this time, fertilizers are not applied, because when planting enough nutrients were introduced.
- The first fertilizer is carried out at the end of May. 20 g of urea are scattered under the bush, and then 20 l of water is irrigated.
- At the end of June, a second top dressing of 20 g of superphosphate dissolved in 20 l of water is performed. This solution is enough for one adult shrub.
- In mid-July, hydrangea is watered with a mullein solution made from 3 kg of mullein and 10 l of water. This amount of fertilizer is enough for one plant.
During the first 3 years of growth, the plant does not require shaping pruning. During this period, sanitary removal of improperly growing, damaged or dry branches is carried out. When the plant reaches 4 years of age, it is necessary to cut the shoots to a length of 4 buds.
Important! In order to protect the hydrangea buds from freezing in the winter, pruning of inflorescences is carried out in the spring.
This procedure will contribute to better flowering. Starting from the age of 6, you need to trim to rejuvenate. To do this, cut out up to 3 lignified shoots on a ring.
Formation of standard hydrangea
Standard hydrangea has a very attractive appearance and allows you to replay the landscape design in a new way. Under this kind of shrub, you can place flower beds of annual or perennial flowers, as well as arrange stone frescoes.
In order to form a stem at hydrangea, it is necessary immediately after planting a seedling to insert a peg into the ground and tie a plant to it. In the first year in the summer, it is necessary to cut off all the shoots to 3 buds 2 times.
In the summer of next year, all branches are cut into a ring, and the main shoot is shortened by 15 cm.Such manipulations are carried out until the boom reaches growth in a meter or more. After this moment, the shoots are not completely cut out, but only pinched at the level of 4 buds in order to form a magnificent crown.
1 - planted young plant with buds; 2 - spring shortening of the shoot; 3 - bending continuation shoot; 4 - pinch of shoots of the current year; 5 - removal of last year's shoots for the formation of the stem; 6 - removal of shoots formed on the stem; 7 - crown formation from last year's shoots; 8 - a shtamb 0.5 - 1 m high.
Shelter for the winter
In order for the plant to winter well, a number of preparatory procedures are necessary. First, you should remove the area from excess vegetation and mulch the soil near the trunk to a height of 8 cm. The shoots of young plants are bent to the soil and fixed with a metal bracket. On top cover with coniferous branches or burlap.
In order not to acquire new seedlings in the nursery, the gardener can propagate the shrubs already in the garden.
To do this, you can use the methods:
- propagation by layering.
The above methods are simple and clear in execution. Therefore, even a beginner in gardening will cope with them.
For propagation by layering, it is necessary to select the longest young shoot, the lower tier of branches, on an adult shrub. It is bent to the soil, fixed with a special bracket and instilled into the bend. Throughout the summer season, layering is watered and spud. Next year in the spring, he will be ready for separation from the mother bush.
Propagation by cuttings begins in the summer. Young shoots of 15 cm long are cut from the bush. They are cut from two sides: above the kidney and under it. Then place the bottom side in the solution of the drug "Kornevin", where the cuttings should be for 3 hours.
Planting material is planted in a pre-prepared area. On it it is necessary to dig the soil 30–40 cm in depth, introducing 10 kg of peat, 10 kg of sand for each 1 m². Cuttings are planted in a substrate at a distance of 5 cm from each other, they are buried by 2 cm.
Then it is necessary to perform the irrigation procedure (about 200 ml of water for each stalk). For a period of 14 days, all cuttings are covered with polyethylene or plastic bottles to create a greenhouse effect.
After this period, they remove the shelter and subsequently produce such care:
- watering 200 ml each week for one stalk;
- loosening the soil 1 cm deep after irrigation.
With the advent of autumn, the cuttings will form the root system, but will not yet be ready for transplantation. Therefore, they are covered with cardboard or other covering material and left for the winter. In the spring, planting material can be transplanted to a new place.
Did you know? Inhabitants of Japan call hydrangea “adzsai”, which means “purple sunny flower”.
Diseases, pests and their control
With good care, hydrangea is rarely exposed to insect pests. But, if there is a lot of weed grass and fruit trees in the garden, then the bush can become infected with aphids. Small insects quickly spread over the entire surface of the shoots and suck out the juice from them. The leaves become twisted, a whitish coating forms on them. Due to the invasion of aphids, the plant is poorly developed and blooms.
- Timely cleaning of the site from debris and weed grass.
- Manual removal of damaged leaf plates and shoots.
- Irrigation with the drug "Karbofos" 90 g per 10 liters of water.
When the plant does not receive enough iron and water, chlorosis begins to develop. The most favorable conditions for its development are dry, warm weather. Due to illness, hydrangea leaf plates lose their color and become lethargic. The disease provokes a slowdown in development and wilting of branches.
To combat chlorosis, a solution of 1% copper sulfate, diluted in a proportion of 1:10, is used.
Kiushu hydrangea is excellent for decorating landscape zones, it is used to form compositions, single plantings and hedges. If desired, the gardener can form a standard for this plant, which will more advantageously emphasize its dignity and will allow to grow annual flowers under the bush.
