Hortensia is a southern plant and is most commonly found in Siberia as an indoor flower. However, some gardeners are able to grow hydrangea in the open field. Secrets and recommendations of proper planting hydrangeas in Siberia will take a closer look.
How to choose a variety of hydrangeas for Siberia
The world knows about 30 species of a perennial plant, but there are many varieties that can withstand severe frosts. To plant pleased with abundant flowering, it is better to buy seedlings grown in local cold conditions. 
It is recommended to acquire seedlings from experienced gardeners, in which not for the first year hydrangeas are blooming on plots. Based on their advice, we can definitely say that frost withstand tree and paniculate plant species. Hydrangeas of Siberia Limelight, Magic Flute, Pink Diamond perfectly feel themselves - all these varieties of varieties have their own color range and size of inflorescence.
If the flower is grown in a small area, suitable "Sanday" and "Vinyl Fresh", which reach a height of 1 m. There are small varieties that germinate up to 65 cm. They are perfectly take root in cold conditions. 
Features of landing in a cold climate
Seedlings best take root at the age of 5 years. In order for hydrangea in Siberia to get accustomed and grow well, planting should be done in a special way, taking into account the climate of the area. For this, a special microclimate is created: seedlings need to be protected from the wind and planted in medium-acidic soil, which includes sod, sand, leaf soil and peat. This provides suitable lighting.
Did you know? Sometimes hydrangea is called French. This serves as a reminder that the entire Western world learned about the plant through the first round-the-world expedition, perpetrated by the French.
Lighting provision
When a variety is already selected, it is necessary to determine its further place of residence. In Siberia with a harsh climate, you need to carefully approach the issue of planting hydrangeas. To begin with, protect the future plant from the wind - plant seedlings near the solid hedge.
Such shrubs are perfect for a hedge: white turf, calinifolia, aronia, spirea, lilac.
Hortensia loves the light, but it does not tolerate the direct rays of the sun very well. It is better to choose a shade for the flower.
What should be the soil for planting
For the bushes soil is very important. Hydrangea does not tolerate an alkaline soil, so the best soil for growing a plant is low or medium acid. This soil should consist of sand, leaves, peat and sod land. Then the plant will delight its abundant flowering.
Landing instructions
To properly plant hydrangea, you must follow the instructions and recommendations:
- prepare a place in the spring, for planting you need to allocate areas of 0.5 × 0.5 × 0.5 m;
- the distance between the bushes should be 2.5 m;
- cut the roots, shoots, leaving a few buds;
- you can not deepen the roots of the plant, it is necessary to water abundantly and cover the soil with mulch.
Preparing a pit for planting
When you have dealt with the landing site, you need to prepare a hole:
- The soil and dimensions are taken into account: small flower seedlings grow into large bushes, therefore the fertilized pit must be sufficiently large - 50 × 50 cm or more.
- For large seedlings, a pit is made 80 × 80 cm, up to 60 cm deep. It all depends on the size of the roots.
- 3 buckets of water are poured into the pit and left overnight to soak the earth. Peat and humus with sand and fertilizers are added in the morning (proportion: 2: 1: 1: 2). Organic fertilizers and minerals are also added there. Pine needles are suitable for extra acidity. The mixture completely fills the hole.
- Hortense does not like lime and dies because of this.
- The last stage of preparation - pruning shoots and roots. The roots are shortened, and the shoots are pruned to 6 buds.
Seedling planting scheme
According to the scheme you need to perform the following steps:
- seedlings are planted in a suitable place, dripping garden soil;
- the neck of the root of the flower is on a level with the ground; it is not necessary to dig in and leave open too;
- for good development, after planting, it is necessary to water once, after pouring on the ground a mixture of needles, leaves, peat - such a pillow keeps moisture for a long time;
- after planting, before the seedling has taken root, it is necessary to create comfort and protection of the flower.
Terms of care for cold-resistant hydrangeas
Flower after rooting unpretentious in the care. Hortensia, planted in Siberia, requires the same care as other flowers, but with some peculiarities. Another name for the plant is “hydrangia”, which means “vessel for moisture”. This speaks of the love of the plant to water procedures, so watering comes first.
Did you know? Hydrangea is one of the rare flowers that can accumulate aluminum from acidic soil. Due to this, compounds that give a blue tint of colors are formed.
Features trimming hydrangeas
That the bush is well formed, the plant must be trimmed in time:
- in the fall cut off all flowering inflorescences;
- in the spring at the tree flower cut off the shoots, leaving 5 buds. The paniculate variety is cut a little differently: the main shoots are cut to the desired height, and 3 buds are left on the side shoots.
Important! Old shrubs are also rejuvenated if you apply a strong pruning and remove all the shoots, down to the old wood.
Watering, fertilizer, dressing
The flower loves moisture, so the ground should never be left dry. In addition, potassium permanganate can be added to the water and regular soil mulching with sawdust and leaves under the shrub can be carried out. This method perfectly retains moisture for a long period.
Top dressing promotes long and plentiful flowering. Liquid manure will be moderate in quantity, mineral balanced fertilizers - 25 g per 10 l of water during irrigation. For an adult bush use 3 buckets.
During one season, 4 additional feeding occurs: at the beginning of sap flow, during the blooming of buds, in summer in July and in autumn, preparing the plant for wintering.
The most beautiful paniculate hydrangea is considered to be Phantom. Check out the technique of growing this beautiful shrub.
Shrub reproduction
There are 5 methods of breeding bushes: seed, grafting, layering, offspring, dividing the bush. The best is the cutting method, which is common among gardeners. 
Green grafting occurs at the time of flowering buds. It is recommended to cut the cuttings from young hydrangeas. If you have an old shrub, anti-aging pruning is done. The important point is also the preservation of moisture in the tissues, since successful rooting depends on it. 
Features of plant conservation in winter
Siberian frosts are famous for their strength, so the hydrangea hides under a safe shelter. Roots need warming: they are covered with rotted manure. You can also create a pillow of peat and dry leaves, which is placed in a thick layer up to 20 cm.
After the snowfalls, you can additionally warm the hydrangea with snow, filling a large layer under the shrub. This not only warms the shrub, but also nourishes it with moisture.
Important! Do not open the bush completely immediately after warming: the plant can ruin the spring frost.
Major diseases and pests affecting the plant
Each flower is prone to attacks of parasites and diseases, and hydrangea is no exception. To prevent the bush from dying, you should cure the flower in time. What diseases are dangerous to the plant first? 
Mealy dew is a common disease for all varieties. When spraying is performed: add a base in the water with proportions of 30 g of substance to 10 liters of water. Another method - 80 g Bordeaux mixture per 10 liters of water.
Aphid also attacks the plant. The flower is cut as follows: in 300 g of purified garlic, 10 liters of water are poured, after which 50 g of laundry soap is added. Sprayed the plant until full recovery.
