The plant has high winter hardiness and is able to survive frosts from -40 to -45 degrees. Pruning is discarded if the plant hibernates under a thick layer of snow. In the conditions of modern winters in the Moscow region, rains more often "delight" residents than snowfalls.

In the cold season, gardeners are faced with two problems - damping and decay. Based on this, they conclude that the delphinium must be cut for the winter. Such a process cannot be left to chance.

Reasons why flowers can not endure winter well

After winter, a person may find that his pet is gone. Under the force of various factors, the delphinium dies. There are several reasons why the flower cannot stand the winter.

Unsuitable climate

Delphinium, as mentioned earlier, tolerates even the most extreme temperatures under a cover of snow. A person who decides to grow a flower must take into account the climatic features of the southern regions. In winter, the weather often changes, and the temperature drops are very sharp. Whether the delphinium will survive the coldest season depends on the type of plant.

Inattention on the part of a person can cause disappointment in a delphinium. Therefore, people often refuse to grow it.

correct pruning

You can promote re-flowering and help the delphinium survive the winter by pruning the inflorescence above the top leaf. The procedure is also carried out just before the colds. Unfortunately, many mistakes are made again during trimming.

After that, the stems are left at a height of 15-30 cm from the soil surface. From above, the tips are covered with clay. To prevent water from getting inside, it is enough to break the stems, leaving them bent.

When to prune a delphinium in autumn?

The time to trim the stems depends on the flowering period of the variety. It can range from 1 to 2 weeks. On average, the procedure falls on the end of September.

Storage methods

With the onset of winter, gardeners are considering 2 options for preparing a delphinium for winter:

  • trimming;
  • use of shelter.

plant hybrids

In the first case, the stems are cut off, and the edges are covered with clay. The root area is sprinkled with mulch. The option is more suitable for snowy winters.

The second preservation method also involves pruning the stems and treating them with clay. In order to prevent the plant from dying, use additional shelter. Coniferous branches are most often chosen. This approach will save the delphinium in a wet winter.

Preservation nuances

The correct procedure for preparing a delphinium for wintering will save it from the threat of developing diseases. Many gardeners are pruning at the wrong time. As a rule, they forget to do it on time and delay the procedure. This will not only affect the plant's ability to endure the winter, but also prevent the full development of the buds.

removal of seeds

Experts advise against stimulating kidney formation in the fall. They also recommend giving up the idea of ​​re-flowering before winter. Delphinium stems are pruned at the onset of stable cold weather.

If the flowers were planted in the spring, they continue their development until the onset of cold weather. In late autumn, they can be in the budding stage. In this case, it is not clear to a person whether they are ready for wintering or not.

If the plant is young, as a rule, by late autumn, the process of bud formation has time to occur. New flowers tolerate winters better, unlike representatives that have been growing in the garden for a long time. This is because they are less prone to root rot.

dive delphinium

In regions with warm winters, people are ready for frequent thaws. Knowing the temperature regime, they carefully prepare the plants for wintering. A canopy or something similar to a hut is erected over the landing. Thus, the delphinium is protected from excess moisture and frequent gusts of wind.

Insulation material

If new plants are planted in the spring, they need extra cover. Straw will help to save from frost and a large amount of snow. It is an excellent alternative to coniferous branches.

It is not recommended to use peat or leaves to hide the delphinium. They are able to retain moisture. In turn, this leads to the development of the fungus and the diseases associated with it. Excess moisture attracts slugs and various pests.

straw shelter

After the snow melts in early spring, the delphinium wakes up and is ready to grow. At the same time, night frosts are not a hindrance. There are times when the plant is poorly rooted. Thus, it is deepened so that the kidneys are not damaged.

Delphinium is a beautiful and unusual plant. Its growth and full development depends on the conditions that will be created by man. Disregard of simple rules leads to the fact that the plant dies. This issue is especially relevant in the winter season. A little effort and attention of gardeners, and the delphinium will thank with abundant flowering, decorate the flower beds throughout the summer.
