“Each vegetable has its own time”, and each plant has its own optimal time for landing. Anyone who has experienced planting is well aware that the hot season for planting is spring and autumn.

There is one beautiful and rather whimsical plant in the garden - rough macrophylla hydrangea. Just incredibly beautiful and super whimsical. She is famous for her beautiful blue flowers, but it does not tolerate frost very well. Although, in order to enjoy its unprecedented beauty during the flowering period, it is advisable to spend a lot of time every year, trying to take care of it with all your might.

As a rule, the macrophylla begins to bloom from last year's shoots, and, precisely for this reason, it is incredibly important throughout the winter to ensure that it does not freeze and survive.

Hydrangea aspera care

Before you cover it for the winter, it is best to cut off all chaotic and weak shoots, as well as remove all crooked and thin branches.
Below we consider how a rough macrophylla is properly covered for the winter:

in autumn, it is necessary to free the shoots from all leaves
the bush needs to be divided into several bundles consisting of stems. True, you should be more careful, despite the fact that the shoots are flexible, they can still be accidentally broken.
then it is necessary to tie the bundles together, tilt them, and, as it were, strengthen them near the ground
when the shoots are pinned, they need to be covered with a non-woven covering material, such as, for example, agrotex
after that, the plant should be well sprinkled with dry, fallen leaves
on it, already on top of the leaves, you can put bags of sugar, well, or something similar, in order to protect the rough from excessive moisture
at the end, you will need to put a small piece of an old carpet on an already wrapped hydrangea bush

Of course, you can fill the bush with some leaves from the very beginning, and only then cover it with additional materials described above. But, nevertheless, in order to make it easier in the spring to free the plant from everything that has accumulated on it, it is best to put covering material from the very beginning. Thus, the shelter will be easier to remove, and there will be no danger of damaging the plant, which will swell buds by spring.

By the way, do not be afraid to wrap too much this species hydrangeas, because she is not a rose, an extra layer of “insulation” will not be harmful to her.

Well, the rough aspera successfully overwintered. Sometimes in the spring, after you unravel it, you can notice a slight mold on the leaves. There is nothing terrible here, so do not be afraid. It can be washed off with a solution of potassium permanganate, or generally with clean water.
With the onset of spring, do not be in a hurry to unravel it. If suddenly frosts suddenly come to you, then all efforts to heat it in winter time years will be in vain!

reference Information

Most of the plant species are shrubs (their height is 1 - 3 meters), some specimens are small trees, others are lianas.

Crops are either deciduous or evergreen. The most widespread are the first species, which belong to plants of a temperate climate.

Hydrangea rough macrophylla

Hydrangea gets its name from the fusion of two Greek words("hydro" - "water", "angelon" - "vessel"). This means that the seed pods are like pitchers or the plants are very fond of moisture.

There is another legend: in the 18th century, the Frenchman Philibert Commerson, a doctor and naturalist, traveled around Japan.

After all, none of local residents could not answer the name of the flower.

Shrubs have thick branches.
Large, flat inflorescences are white and lilac. The last specimens are distinguished by small lilac-purple flowers. The flowers are in the middle. Around them are snow-white large flowers.
The leaves are very decorative, large (length - 35 cm, width - 25 cm). Young leaves are velvety, dark green. At the end summer season they are brown-orange.
The height of the bush (1.5-2.5 m.). Width (1.2 m.).
Hydrangea is highly winter hardy. It can be grown in regions with difficult climatic conditions(including in the Moscow region).
Hydrangea bloom (August-September).

Planting a plant

For the plant, choose a warm, well-protected area from strong winds. It is best to choose a shade or partial shade, because the hot midday sun and direct rays of light have a bad effect on the hydrangea.

The soil should be nutritious, neutral, slightly acidified.

For the plant, choose a warm, well-protected area from strong winds.

It is best to choose a seedling aged 2 - 3 years.

The plant can be planted in spring (after the ground has melted) or autumn (September).

Landing technology

Making a landing hole different size, depending on the soil:

light earth (depth - 50 cm, width - 40 cm);
loam (60 cm x 50 cm);
clay soils (70 cm x 60 cm).

Chipped brick or crushed stone 15 cm thick is poured at the bottom of the pit. Such a layer will perform the function of drainage.

They lay fertile soil with a layer of 10 - 20 cm. Humus, peat are added to it, mineral fertilizer(50 gr.).

Bushes are planted, leaving a distance of at least 1.5 m between them. The root neck should not be buried. Leave it just above ground level.

The tree is placed in the hole. Gently straighten the roots. Sprinkle with earth, tamp. Water abundantly (use at least 2 - 3 buckets of water).

Attention! If the plant is planted in dry weather, then the seedling should be sprayed with water.

Care

Rough hydrangea required a large number of water. Its deficiency negatively affects the development and flowering of the bush. Therefore, the plant is watered abundantly (pour 3-5 buckets of liquid under the bush), often (at least 2 times a week).

In the cloudy rainy weather one irrigation will suffice. Mulching with peat will help retain moisture (10 cm layer).

Trunk circles must be loosened at least 2 times per season.

Important! Hydrangea roots are in upper layers earth. Therefore, loosening can only be carried out to a depth of 5 - 6 centimeters.

The first two years, the young plant should be given rest. He has enough nutrients used during landing. You just need to care for hydrangeas as needed.

Two years later in early spring, bushes begin to feed with mineral complexes. During the budding period, plants are fertilized with superphosphate, potassium sulfate, mullein (ratio with water 1:10). To make the branches stronger, hydrangeas are irrigated every 30 days with a solution of potassium permanganate (2 mg / 10 l of water).

The first couple of years, the bushes do not need to be cut. They need to be strong. From the third year in the spring (the last days of March - the beginning of April), pruning is carried out. Required work must be done before the moment of sap flow. To begin with, diseased, damaged, broken shoots and branches are removed. Then all last year's shoots are cut off, retreating by 3 buds.

Despite the excellent frost resistance of rough hydrangea for the winter, the near-stem zones should be wrapped with dry leaves, sawdust, and covering material.
