Blackberry Polar is a godsend for an inexperienced gardener, because it is very easy to care for her. Even the landing process does not involve any particular difficulties. See for yourself by examining the main stages of this process.

1. For landing is chosen cool weather. In a warm area, the landing of blackberries is carried out in early autumn. For planting in the middle zone and the Moscow region, it is necessary to choose the spring period. It is important that all frosts pass, otherwise the root will be damaged and the plant will die or be sick and weak.
2. For the Polar variety, it’s better to choose a sunny place without drafts. The plant does not like the high flow of groundwater, grows well on organic loam with low acidity.
3. For landing it is necessary to prepare a hole half a meter wide and deep. More than half of the pit is filled with fertile, nutritious soil and well shed water. In this form, the pit is left for two weeks. To reduce the acidity of the mail you need to add lime. It is possible to make a dense soil looser with the help of sand and organic matter.
4. Before planting the seedling, the open root is soaked for 12 hours, and the container plant is well watered.
5. When forming a blackberry plantation, 2.5 meters should be left between the rows, and at least 1.5 meters should be left in the same row between plants. For industrial breeding, this distance is reduced to 90 cm.
6. Before planting, the plant must be shortened to 15 cm. A hillock forms in the center of the prepared pit, and the seedling root system is spreading around it. The root neck should be deepened by 2 cm. The ground around the plant should be compacted, the surface should be mulched and watered using at least 10 liters of water.

Blackberry Polar is unpretentious, it does not need to devote much time and create special conditions. To achieve high yields can be with minimal effort, it will be enough just to follow a number of simple rules.

• For a young plant is very important abundant watering. Twice a week it is required to water the blackberry plentifully.In the future, also do not forget about watering, because this culture is moisture-loving. Suffice it to recall that forest blackberry usually grows near rivers. Do not let the root system dry out.
• An adult plant needs a garter. This is a prerequisite. You can use the trellis of any shape and design that will be most convenient for you.
• Feeding is not a prerequisite. The plant will not suffer, can not be said about the yield - it will decrease. Since the beginning of spring it is recommended to apply nitrogen fertilizers. During flowering, in its early stage, it is necessary to use mineral complexes. After harvesting, potassium monophosphate is used. Good use foliar feedings.
• From the lack of iron in the soil on the plant may appear signs of chlorosis. This problem is eliminated by adding iron chelate or a chelate complex to foliar feedings.
• Loosening necessarily held twice a season.

• During the growing season, mulching is carried out using red or high peat. Thus, the soil will be acidified, and the root system will be provided with air and moisture. Peat will also prevent the growth of weeds.
• After the end of fruiting pruning of the shoots. With this process it is impossible to delay, so that the young shoots have time to increase the wood before the onset of the first frost.
• Side shoots need to pinch to reach a length of 45 cm. In this case, the branching will take place better. Do not leave broken, weak and diseased whips.
• Cover the plant is necessary in regions characterized by frosts below -15 degrees. To do this, the shoots are removed from the trellis and pinned to the ground. Shelter is constructed from the spruce branches, agrofibre, corn stalks or straw. Reviews of gardeners, who fell in love with this variety of berry crops, indicate the possibility of increasing yields several times only due to proper shelter of the bush.
• This variety of blackberry is very rarely sick, because it is characterized by high resistance to both diseases and pests. As a preventive measure in spring, bushes can be treated with a copper-containing preparation.

This variety has many advantages, but there are also some negative characteristics. Let's start with the pleasant - we will explore the positive aspects of the blackberry Polar:

• acceptability with respect to thickened landings;
• the possibility of using for industrial purposes and growing in private areas near the house;

• powerful shoots create some difficulties in preparing the bush for the winter;
