Hosta Blue Angel boarding and leaving

It is necessary to plant the Blue Angel host with the onset of spring and must start by choosing a suitable place. If you plant a crop in areas that are exposed to direct sunlight, it will lose its bluish tint and acquire a normal green color. This is the reason why shaded areas should be chosen. A perennial plant will do well under the crown of a tree or any other large plant.

The blue angel prefers slightly acidic and moist soil, but the bottom of the planting pit must be covered with a thick layer of drainage. Loamy and sandy soil adversely affects the active development. It should be borne in mind that the culture does not tolerate drafts, so the garden bed for planting it must be protected from the cold wind flows.

Attention! When planning a group planting, hosts should maintain a distance between the planting pits of at least 80 cm. Watering should be done under the root system, any other method will lead to deterioration of the foliage.

Before planting the Blue Angel hostu, it is recommended to loosen the soil, and then add a complex fertilizer to stimulate the plant roots.

It is necessary to dig a planting hole, the depth of which should be twice the length of the roots of the culture. Be sure to monitor the level of the root collar (it should be flush with the ground).

The root system of the seedling must be straightened during planting, and then sprinkled with earth. The soil should be rolled and mulched using bark. The final step will be abundant watering of the hosts.

Pests and diseases of blue hosts

The blue hosta conceived can be damaged by slugs and snails. They feed on succulent foliage, and their silvery traces spoil the appearance of the plant.

As for small rodents, they pose a danger to the root system of a perennial. In order to fight pests, you need to scatter a poisonous bait around after planting the seedlings.

Host parasite attacks are most common in winter. If, with the onset of spring, the culture does not have fresh foliage, this indicates damage to the roots by insects. To check this, the plant must be removed from the ground and carefully examined.

Another dangerous pest for a plant such as the blue hosta is the caterpillar, which can destroy perennials in just one night. You need to fight insects with the help of special chemicals - insecticides.

Nematodes are dangerous pests that destroy the host by feeding on its foliage. It is possible to determine that the plant is affected by nematode worms by the presence of brown stripes located on the veins of the leaf plates.

In addition to insects and rodents, perennials can die from fungal diseases and viruses.The first warning signs of damage are represented by yellow spots and dots on the leaves.

Important! To date, there are no effective ways to fight viruses, so a sick host should be dug up and burned so that the infection does not spread to other plants.

Fungal infection can lead to phylostictosis. The most vulnerable are those plants that were weakened due to heavy wintering, as well as those in which the top froze under the influence of repeated frosts. Traces of the disease are represented by large merging brown spots that cover a grayish bloom.

Another common disease of blue hosta is anthracnose, which affects those bushes that have become weakened due to a lack of minerals. The disease can also be triggered by excessive moisture levels. The initial stage of anthracnose must be treated by using systemic fungicides such as Abiga Peak, Bordeaux mixture and Gamair.

The blue hosta is a versatile plant that prefers to grow in shaded areas. She is able to get along with many plants, as she has no special requirements for care and cultivation. Hosta can be combined with plants such as lungwort, fern, aquilegia, astilba and others. You can add special charm to a garden plot by decorating a fountain, a pond perimeter or an artificial waterfall with a host.
