Hydrangea is a whimsical plant, so when planting it should carefully choose and prepare the site. It is also required to pay due attention to the choice of seedling. What to look for when choosing a place for landing, as well as the rules for the purchase of planting material, read on.
Choosing a seedling and a place to grow
You need to buy hydrangea seedlings in a specialized store or nursery. The plant must be healthy, the presence of dryness and diaper rash is unacceptable on the surface of the branches.
You should not purchase planting material on which there are at least 3 well-developed shoots - such a bush has not yet matured for transplanting into open ground.
The area for hydrangea cultivation should be well-lit or half-shaded. Landing can be carried out near residential buildings or near large trees.
Important! Do not plant hydrangea in places with possible flooding - stagnation of moisture can provoke the development of fungal diseases.
Hydrangea variety Dentel de Gorron is preferably grown on well-drained soils with acidic pH. Prepare a site for landing should be in the fall. It is cleaned of plant debris, then 5 kg of humus, 10 kg of river sand and 10 kg of peat per 1 m² area are introduced into the soil.
Digging should be carried out 30-40 cm in depth. By spring planting, the soil substrate will become more loose and moisture permeable.
The first step in the landing is to dig a hole. Its width should be 30 cm and a depth of 40 cm. The next step will be the laying of the drainage base in the hole. To do this, shells or pebbles are poured into the pit. Their layer should be up to 5 cm. Next, prepare a nutrient substrate and begin to plant.
- From mixed in equal amounts of sand, peat and earth, a substrate is prepared. 5 kg of humus and 30 g of superphosphate are added to it.
- The prepared substrate is poured with a layer of 10 cm above the drainage and a small slide is formed from it.
- Next, carefully plant the seedling in the hole and distribute the roots along the embankment from the substrate.
- To the top of the pit, they fill up the soil and ram.
- Water the plant with 5 liters of water and mulch with peat.
How to care for a variety
Despite the whimsicalness of the plant, subject to the rules of care, you can easily grow a healthy bush, which will annually delight with its flowering. For this, it is necessary to observe the regime of watering and fertilizing.
Also an important factor affecting the development of the plant is timely pruning and preparation for the winter period. With proper care, the plant will be reliably protected from disease.
Watering and feeding
Hydrangea is watered regularly. It should not be allowed for an earthen lump near the trunk to dry out, therefore, during heavy rains, let’s water once a month. In the driest months, watering should be more frequent - every week.
One adult plant will require 15–20 L of water. Watering the plant is necessary, starting from the spring thaw and ending 2 weeks before the onset of autumn cold weather.
To hydrangea was beautiful and bloomed well, it is necessary to carry out 3 dressings:
- The first is carried out during the budding period. For one plant, you will need to add 20 l of a solution prepared from 20 g of urea and 20 l of water.
- In June, top dressing is made from 20 g of superphosphate, which is dissolved in 20 l of water. This solution is enough for one bush.
- In early July, an organic top dressing of 3 kg of mullein diluted with 10 liters of water is introduced. This solution is enough for one plant.
After planting a plant in open ground for 3 years, only sanitary pruning is carried out. It involves the removal of improperly growing, damaged or dry branches. Inflorescences that have faded are also removed: they are cut in spring or autumn. Experienced gardeners recommend pruning inflorescences in the spring to protect the buds from freezing in winter.
From the age of 4 years in the spring, pruning of all shoots is carried out. They are shortened to the 4th kidney. Such manipulation will contribute to abundant flowering. From the age of 6, anti-aging pruning is performed. It involves the removal of 1 to 3 lignified shoots. The slice is made at the very root.
Removing shoots should only be done with sharpened and sanitized tools. After the pruning procedure, all sections on the shoots must be covered with garden varieties, which will facilitate rapid healing and prevent the penetration of infection into the wound site.
Important! When conducting anti-aging pruning, one should take into account the fact that the number of shoots removed should not exceed 1/4 of their total mass.
Preparation for winter is carried out starting from the first of September. The branches of the plant exempt from the lower tier of foliage. The remaining leaves are removed 2 weeks before the cold.
In mid-October, a mulching procedure is carried out. Peat is used as the material, which is laid in a continuous layer to a height of 8 cm. After the temperature reaches 0 ° C, the plant is covered with burlap or lapnik.
In order not to purchase hydrangea seedlings in the nursery, you can propagate already existing plants on the site. The easiest and most common ways to obtain new planting material is to divide the bush and cuttings. They are not costly and not complicated, so even a beginner gardener will cope with them. These methods of reproduction will allow you to get new seedlings in a fairly short time.
For propagation by green cuttings, it is necessary to cut branches 15 cm long in July.They are cut off above the upper and under the lower kidney and placed in a solution of the drug "Kornevin" for 3 hours. After planted on the site in a specially prepared substrate, consisting of mixed in equal amounts of sand, peat and soil.
Each stalk is buried in the ground to a depth of 2 cm, then watered. For 2 weeks, the twigs are kept under cover from plastic bottles or plastic film.
After this period, the shelter is removed and further taken care of by the plant:
- watering once a week in an amount of 200 g per one stalk;
- loosening the soil and hilling branches after each irrigation.
With the onset of autumn, cuttings will form the root system. For the winter period they are covered with cardboard or burlap, and next spring they are planted in a permanent place. As a material for propagation, you can also take lignified shoots. They are cut so that 3-4 buds remain on the handle. The lower cut is done obliquely, the upper - along. For 3 hours, the branches are placed in a solution of the drug "Kornevin."
Further, as in the case of green cuttings, a nutrient substrate is prepared and branches are planted in the soil. They are deepened 2-3 cm deep and covered with polyethylene. By the autumn period, cuttings will take root, but the plants will not be ready for transplanting to a new place, so they must be covered with burlap until spring.
Dividing the bush
Reproduction by dividing the bush is carried out in the spring.
To divide the plant into parts, you must:
- Trim branches to a length of 4 buds.
- Water the ground near the bush in order to soften it and dig up the bush. This procedure should be carried out with utmost care so as not to damage the rhizome.
- Having uprooted a bush from the earth, it is divided into several parts. In places where the roots are too connected, they can be carefully cut with a sharp knife.
- Separate parts are seated in new places.
Diseases and Pests
Variety Dentel de Gorron has good immunity to diseases and pests. But, if the season is too wet or dry, the shrub can be affected by diseases such as chlorosis and powdery mildew.
Did you know? The Japanese name for hydrangea is “Adzisai”, which means “purple sunny flower”.
Chlorosis develops in dry, calm weather. It provokes a lack of iron and moisture. The manifestation of the disease is easy to notice by signs such as discoloration of the leaf plates and the appearance of brown spots on them. The disease leads to a slowdown in growth and wilting of shoots.
The fight against chlorosis involves:
- Removing damaged leaves and shoots.
- Irrigation of a plant with a solution of 1% copper sulfate (100 g per 10 l of water).
Powdery mildew is a fungal infection that develops rapidly in warm, humid conditions. It appears in the form of a white coating on the surface of sheet plates. Over time, the infected areas of the plant become black and die. The winter hardiness of the shrub decreases, its growth slows down.
Powdery Mildew Control:
- Manual cleaning of infected shoots and their burning.
- Spraying with a 1% solution of Bordeaux liquid (100 g per 10 liters of water).
- Use of the drug "Fundazole" (1.5 g per 1.5 liters of water).
Hydrangea Dentel de Gorron may be invaded by aphids. This insect settles on shoots, leaves, flower ovaries and sucks the juice from them. The invasion of aphids leads to a slowdown in plant growth and wilting of branches.
- Irrigation with a soap-ash solution made from 100 g of soap, 200 g of wood ash and 10 l of water.
- Timely cleaning of weed grass on the site.
- Manual removal of shoots on which insects settled.
So, hydrangea Dentel de Gorron is a beautiful ornamental shrub with large flowers, for which it is widely used in landscape design. Despite the whimsical care, many gardeners are happy to plant a plant in areas in order to decorate the garden.
