Raspberry "Polka", or Rubus idaeus "Polka", bred at the Institute of Horticulture and Floriculture. The variety was obtained by Polish breeders as a result of crossing the R-89141 line and the OTM-Bliss variety, well known to gardeners. For more than twenty years, the Polka variety has been popular and in demand not only in our country, but also abroad.

The main characteristics of the variety

Remontant raspberry "Polka", the description of which is well known to both experienced and novice breeders, forms medium-sized plants. Strong and powerful shoots reach a height of 1.5-1.7 m. Spikes on the shoots are weakly expressed, which greatly facilitates plant care and harvesting. Raspberry bushes of this variety do not require the use of additional support in the form of supporting columns or trellis structures.

Berries of raspberry varieties "Polka" are very large. With proper care, the length of the berry exceeds 2-2.5 cm. The average mass of marketable berries under favorable soil and climatic conditions in the cultivation region reaches 10-12 g. Berries have a slightly elongated shape, sufficient density. The surface is shiny, almost no pubescence. The ripe berry has a saturated, almost purple color. A flesh of dessert flavor, with a pronounced varietal aroma. Taste with a very balanced sugar and acid content.

Indicators of total productivity during cultivation of varieties on a garden or garden plot are almost entirely dependent on agricultural technology and weather conditions. Usually, from each bush it is possible to collect at least 2-4.5 kg of high-quality berries per season. The variety is characterized by a lack of susceptibility to damage by gray rot and is practically not damaged by a spider mite. The relatively late period of fruiting allows plants to avoid damage to the most common diseases.

Features of planting and reproduction

Raspberry "Polka" should be planted in areas with light and fertile soils, without stagnation of moisture. The optimal width between rows is approximately 1.5 m, and the distance between the seedlings in the same row should be no more than 0.5–1 m. Planting in trellis in two rows with a distance of no more than 50–60 cm gives a good result. The variety "Polka" is light-loving and moisture-loving. When laying a raspberry, rows for planting are best placed from north to south.

Raspberries are propagated vegetatively using shoots. Most gardeners propagate raspberries of this variety with green root offspring or green cuttings that need to be harvested in late spring from overhead annual shoots. Raspberry "Polka" annually forms a sufficient number of substitution shoots, so that if desired, plants can be very easily propagated independently.

Plant Care Rules

Raspberry "Polka" requires a fairly strict observance of agricultural technology and needs good nutrition. In the first year after planting, seedlings do not need to be tied up, and laterals (lateral branches) are characterized by excellent growth without pinching. The optimal number of shoots per bush should not be more than 7−9 pcs., depending on the age and degree of development of the plant. This variety is very susceptible to abundant watering and top dressing, and also does not tolerate a lack of nitrogen, potassium and organics.

Raspberry shoots "Polka" for the winter period must be cut to a minimum height. This technique allows plants to easily endure winter frosts and get out of winter with a complete absence of losses. In addition, strong pruning allows you to effectively deal with such a dangerous plant parasite as raspberry beetle, and reduces the cost of acquiring modern insecticidal agents, making the crop environmentally cleaner.

Reviews and recommendations

Raspberry "Polka" has a fairly long fruiting. Mass harvesting begins in the first ten days of August and does not stop until the first severe frosts. Numerous positive reviews of gardeners and summer residents indicate the popularity and relevance of this European variety almost everywhere. "Polka" became famous not only for its record productivity, but also for the excellent quality of the berry.

Best of all, this raspberry variety has proven itself when grown in the soil and climatic conditions of central Russia. According to gardeners in the southern regions, Polka does not always tolerate high-temperature conditions and can reduce yield. The way out is the creation of a rocker fence in the form of planting corn or tent raspberries.

How to plant raspberries

In addition, it was noted that the variety is susceptible to diseases of the root system, including root and rot cancer. Nevertheless, "Polka" is very popular not only in home gardening, but also used for commercial cultivation. Ripe berries are suitable for fresh consumption, as well as freezing and processing, have good transportability and are in demand by consumers.
