Many gardeners have long loved such a beautiful and spectacular plant as hydrangea. Fluffy bushes, covered with lush inflorescences, have bright green gear sheets, capable of changing color, but look just luxurious. However, despite unpretentiousness, careful care is required. Attention deserves wintering, which when improper approach can harm the plant or even kill him.
What flowers need shelter?
Hydrangea is represented by approximately 70-80 varieties. Not all of them are suitable for growing in our country. The plant is quite unpretentious, which cannot but please the gardeners, but not all of his species are winter-hardy. Therefore, he often requires special preparation and shelter for the time of cold.
It should be noted that some grades do not need. Basically it is necessary for young plants for the first 2-3 years of life. As for the southern regions of Russia, such a procedure there in principle is not relevant due to climate.
It is recommended to cover only those species that will bloom on last year’s shoots. Flower kidneys damaged by frosts will not be able to give buds.
It should be noted that Miscellaneous hydrangea can best carry cold. She is not afraid of lowering temperature up to -40 degrees. Therefore, you can do without a serious shelter, it is enough just to cover the earth around the priority circle to guard the root system. If the region is not distinguished by abnormal cooling, you can ignore the moment. It must be said that the stems of the buggy hydrangea very rarely frozen.
Tree hydrangea Also distinguished resistant to lower temperature. However, if the segration area is characterized by strong frosts, you should think about complete shelter, otherwise young shoots can be frozen. But if for any reason to do it did not work out, nothing terrible. The tree will still bloom in the same way, as it is distinguished by rapid restoration with the onset of warm days.
One of the most famous representatives is Large hydrangea. But it is characterized by a low degree of winter hardiness, respectively, experts recommend growing it in a warm or moderate climate. In the northern regions should take care of the shelter. Perhaps full of extinction and will not happen, however, the lush flowering shrub in the future will not please. It should be noted that with age, frost resistance will change.
Any of the varieties need to be covered completely for 2-3 years after landing. Most adult and healthy plants are perfectly tolerated cold.
It’s no secret that different regions of our country differ in climate. Therefore, it is not so difficult to guess that the optimal shelter time will also be varied. The southern strip of Russia may well do without this procedure, but In the colder regions, gardeners begin to think about the shelter even in the late summer and early autumn. You can especially allocate the middle lane and the Moscow region, the Urals, Siberia and the Leningrad region.
As for the middle strip of Russia, the procedures for the cover of plants for the winter will start in the second half of October. Usually, the dates are already falling below 0 degrees at night. For winter-hardy varieties, no complete shelter is required. It must be said that in these latitudes the average air temperature in winter is about -15 degrees, and a number of varieties feels well even with the thermometer readings -35 degrees.
Flowering kidneys in the blurred and tree shrubs will form on new shoots, respectively, light and short-term cold do not apply harm bushes and are not able to adversely affect their appearance. Enough such procedure like mulching. It is worth treating the nearby circle, and the plant will excellence the winter. As for the large-scale hydrangea, it must be hidden.
Flowers appear on the shoots of last year, so you can not allow them to freeze. Also worth covering seedlings whose age is less than 2 years old.
Urals is known for harsh winters. It makes the gardeners approach the preparation for winter very seriously. Bushes are carefully covered in various ways. Preparatory events begin in about October. As for Siberia, it is characterized by anomalous frosts that can hold over long time. Therefore, the most appropriate view for cultivation in this region is a lotway hydrangea. Among the rest, it is characterized by special frost resistance.
but From the closure, it should not be refused, you can organize it from the beginning of October. Large varieties are suitable for growing in pots, which in the cold season can be transferred to the house. Leningrad region is distinguished by rich snowfall. Her climate allows not to make capital winter shelters for hydrangea. It concerns the scattered and tree species. Snow will close the shrub, thereby protecting it from the cold. Large varieties should be covered in about mid October.
Than you can close?
Purchase materials exist different. Some of them are suitable for hiding hydrangea for the winter. Some even permissible to combine. The main of them are considered to be leaves, vegetables, nonwoven materials, polyethylene and burlap. Leaves are organic underpressure material, however, only them will not be enough to protect the hydrangea from frost. From above you need to put something else, only in this case the plant will be warm. However, you can act and the opposite way: first the material is tightened to a special framework, and the leaves fall asleep on top.
Perfectly suitable as shelter Maple leaves and chestnut leaves. They have a significant advantage, as they do not have time for winter. Experts categorically do not recommend using the foliage of fruit trees or berry bushes. Concerning Lapnik branches, they are one of the most common underfloor materials. Most often they are thrown over dry leaves or other shelter, since the sickness itself will be little to protect the hydrangea from frosts. Specially break or cut branches should not, in the forest or park you can find a sufficiently broken material that can be used. It is very convenient if there are own coniferous plants on the site, the remains after the trimming will be quite useful in this case.
Next should be said about nonwoven underfloor material. His role can be performed by Loutrasil or Spanbond. They also enjoy well-deserved in gardeners. Materials are breathable, which is their indisputable advantages.
It is possible to cover the hydrangea in just 2-3 layers, for the middle strip of Russia, this is quite enough, however, in some cases it may be needed 4-5.
If you organize such a shelter, the snow of hydrangea does not need. Material attached to special arcs. In addition, the number of layers can be increased according to temperature changes and add layers closer to winter. Loutrasil is a waterproof material, it is not necessary to remove it too early. Burlap is great for making a shelter for large hydrangea. It must be pulled in 2-3 layers, after which the plastic film is placed on top. It is necessary to monitor so that small intensity remains. At the beginning of the spring, the film is necessarily removed, since the temperature under it will constantly increase with the arrival of heat.
Next should talk about Polyethylene film. It should be noted that the rubberoid can become excellent analog. Film does not have air permeability, which is not a dignity. Yes, it perfectly protects the plant from excess moisture, but in relation to hydrangea it is not particularly required. In addition, with raising temperatures in the shelter, it becomes hot and stuffy. It is best to pull the film on top of the nonwoven material and be sure to leave holes for venting. It will help to exclude condensate education. Polyethylene is removed in early spring.
Rules and advice
Creating shelter – not the only moment when preparing hydrangea to wintering. There is a set of recommendations from experienced gardeners. Events will not require a lot of time and effort, the main thing, to fulfill them on time, and also not forget about the sequence. Most often trimming hortensia is made in early spring. However, before the winter’s offensive, they will also need attention. During this period, sanitary trimming is done, respectively, damaged and dried branches and inflorescences are removed, and the slices are applied to the sections or a special protective agent.
Fallen leaves need to collect and destroy. As for the large-scale hydrangea, foliage from its lower part is retracted at the very beginning of autumn. It helps the shoots to win, which means they will become more frost-resistant. The remaining foliage is removed before the cold, with the exception of the upper part, which will protect flower kidneys. Dried inflorescences in some cases can not be removed, leaving for the winter. This is relevant if the plant is not planned to be covered, respectively, it will delight the eyes with the original appearance. You should not leave a cluster if the shrub will cover any material completely, especially in the case when its age is less than 3 years.
Closer to the beginning of the fall, you can feed the hydrangea in potash-phosphoric fertilizers. Already in mid-September, watering ceases. Large hydrangea can be tried to protect the maximum from excess moisture, covering the film.
If it is possible to create a shelter using a rubberoid, you need to do it as follows. A protective fence is made around 1 meter in height around the bush. From the walls to shoots should remain about 10 centimeters. Dry foliage puts inside, and on top construction is covered with nonwoven material or polyethylene.
As for the removal of the shelter, it is not necessary to hurry here. It is not worth removing it with the arrival of the first heat, as the snow can provoke the appearance of sunburn. Remove the material should not hurry, layer behind the layer. When the snow began to actively melt, you can remove polyethylene. With the establishment of warm days you need to check how the hortensia survived the winter. This is done in about the middle of May, when freezers are no longer expected.
The procedure is best carried out in cloudy weather, it will eliminate the possibility of solar burns. You can open the plant not immediately, but for a start for some time in the morning and evening hours. After that, the mulch is cleaned, and the earth around the bush frills. If it is dry, it is necessary to spend watering. Water in this case must necessarily be warm, it can be slightly overlapping it with citric acid.
After that, pruning is carried out. Each escape should have after it 3-4 kidneys. Dry branches and shoots older than 4 years of age are removed. The procedure is done before the leaves will be formed, except when hydrangea suffered during the winter.
In this situation, it is the first leaves that will show which parts of the plant you need to remove. After trimming, the shrub is given nitric feeding.
