Gardeners and farmers who grow raspberries on their land are always looking for new varieties of berries that are maximally resistant to weather disasters and give high yields. One of these is the Polish raspberry variety Delniva, which has already been successfully tried by many summer residents.

Breeding history of the variety

This variety belongs to the later, however, compared to such species as Polka, it is considered an early one. In a greenhouse, such raspberries bear fruit until the end of November.

Growing regions

The yields of this raspberry are very high. You can count on the harvest from the first year of planting. On average, up to 4 kg of berries can be harvested from each bush, which is perfectly stored and transported, which is important when raspberries are grown on an industrial scale. The berries are easily removed, but do not crumble or darken.

Berries and their taste

In nurseries, shops and private sellers, you can find a huge assortment of seedlings, but how to determine their quality and be sure of the abundance of fruiting already upon purchase?

Growing features

Compact raspberry bushes do not require huge plots of land, do not need the construction of trellises, they have excellent shoot-forming ability, but they have their own growing characteristics.

Site selection and soil preparation

Planting occurs in spring or autumn. Before this, the site is carefully prepared - the weed is removed, the soil is dug up, and it is also moistened. The best soil is loam and chernozem with neutral or low acidity. The best place will be an area that is well lit by the sun, where there are no strong winds and drafts. The fence will be the protection from the wind. A shaded area can lead to stunted growth and reduced yields. In addition, this species does not like lowlands and hills.In one place, the plant is able to grow and give good yields for 8-10 years.

A plentiful and high-quality harvest in the future depends on the correct technology of planting a raspberry bush. It is necessary to choose the right planting material, determine the location and prepare the site.
Raspberry garter is a difficult and painstaking task. This requires time and imagination. But on the other hand, the benefits from this process are enormous. Thanks to the garter, the fruits ripen more intensively and regularly. Bushes are much less deformed, branches do not break off. After the garter, the berries are better preserved, and the greatest achievement at the same time is the convenience of harvesting.

Pruning

The stems are shortened after full harvest, that is, in late autumn. Previously, it is not recommended to do this, since it takes time for the outflow of nutrients into the root system, which is the basis for preparing the plant for the next season of development and fruiting.

The raspberry pruning process is an essential and essential part of caring for your garden and the key to harvesting large, juicy berries. Without pruning, raspberry shoots lose their strength and cease to bear fruit. It is very easy to avoid thickening of the raspberry tree: you only need pruning - in the spring, summer and autumn months.

Watering should be carried out after planting, during flowering and ripening of fruits, as well as during dry periods. The plant has a very high demand for feeding. Replenishment occurs before planting, and then during the period of growth and fruiting. It is not recommended to use nitrogen-containing fertilizers that prevent the plant from rooting.

One of the conditions for proper care of raspberries is proper watering. The rules for watering raspberries are the same for all varieties and varieties of this garden plant. Moistening should be carried out if the soil has dried out by 5 cm or more.
One of the most important conditions for growing large and sweet raspberries is timely fertilization. For each stage of development of the raspberry bush, different feeding is required. Fertilizers that are used at the beginning of the growing season of the plant are not suitable during flowering and ripening of berries.

Frost resistance and preparation for winter

The plant is very resistant to frost, however, after shortening, it is recommended to drop the stems slightly.

Preparing raspberries for winter is another of the stages of berry care. If you start preparing raspberries for wintering in time, then next year you will get a rich harvest of delicious and sweet berries. Winter preparation activities include pruning, feeding, pest control, watering and shelter.
