The variety

Polka is a mid-season strawberry variety. Polka’s fruits are sufficiently large, evenly shaped, intensely red and have a very good flavour. Yields are high. Due to its good frost resistance, Polka is grown a lot in Scandinavia. Its good flavour is also highly appreciated. Besides this, Polka is highly suitable for making jam and juice. Polka’s fruits are shiny, have an intense dark red colour, and are red on the inside. The strawberries have a pleasant sweet & sour strawberry aroma. Polka combines a good flavour with firm fruits. The conical fruits are of medium size, which decreases relatively slowly. Polka creates robust, somewhat closed plants. Polka’s flowers have well developed stamens that provide enough pollen for perfect fruit setting. It is harvested at the same time as Elsanta.

The cultivation

Polka is a highly productive variety, given the right fertilisation and irrigation provisions. What is important is that the plants get sufficient water to enable them to grow. The fruits are easy to pick. If the fruits stay on the plant a bit longer, they can also be picked relatively easily without their calyces. Polka fruits are susceptible to fruit rot (Botrytis cinerea). The plants are susceptible to red core disease (Phytophthore fragariae) and moderately susceptible to crown rot (Phytophthora cactorum). Polka has good resistance to mildew (Sphaerotheca macularis) and Alternaria fruit rot (Alternaria alternata).

Harvest and sales

Polka was developed as an alternative to Senga Sengana for industrial cultivation, but it is mainly used in cultivation for the fresh market in Scandinavia. Polka performs well as a multiyear crop. Polka has good winter hardiness and prefers somewhat heavier soil.
