Description of varieties of raspberries Polka
This type of raspberry is remontant, it bears fruit until frosts come. Ordinary raspberries bear fruit only until mid-summer, and this variety will delight with its berries until September or October.
Grade Advantages
Among the main advantages of the variety are:
- The plant has low shoots, which reach 1.5 meters, so the variety is classified as medium-tall. Trunks are upright, have a small number of spikes, and grow rapidly. The bush is stable, does not bend under the weight of berries.
- Rhizome is powerful, has a fibrous structure. Thanks to this type of root system, the bush does not fill the entire space in the garden.
- The berries are richly red, have a slight "edge". Grow on brushes up to 10 pieces. The fruit has the shape of a cone, reaches 3 cm. The berries are smooth, juicy, fleshy. Weight varies from 10 to 15 g.
- Fruits for 3 months. Flowers appear in mid-July.
- Polka takes root well in open ground and in greenhouses.
- In the bushes themselves, frost resistance is not high. During frosts, raspberries need additional shelter. If the shoots are mowed, then covering raspberries is not required.
- It begins to bear fruit in the first year after transplanting.
- The plant is not afraid of “gray rot” - a common disease of green shrubs. Not dangerous spider mite.
Variety disadvantages
The main disadvantages are:
- The plant does not tolerate temperatures above 35 degrees - the stems and leaves dry out, the fruits are baked.
- The weak point of Polka is the root system, which often suffers from rot, cancer, and is susceptible to verticillous drying.
Properly performed treatment will prevent the occurrence of diseases.
Landing rules
Providing favorable conditions to raspberries Polka, you can count on a good harvest. The main thing is to follow the basic rules of landing.
Landing time
Open-root plants take root well in early spring before the buds open. Harvest in the first summer will not be rich, as the seedlings have not yet gained strength. It is better to plant Polka in the fall, it should be carried out several weeks before frosts, so that the plant has time to take root, get used to the soil and harden before the onset of cold weather. Learn about planting raspberries in the spring from this article.
Seedlings grown in containers and transplanted into the soil, better take root and adapt well. With this type of landing, events can be carried out at any warm time of the year.
Soil preparation and site selection
It is necessary to consider such moments:
- Repair raspberries must be planted in well-lit areas. A small amount of light does not allow the plant to bloom early, fertility decreases and the taste of the berry deteriorates.
- In a relatively cold climate (the central and northern strip of the continent), raspberries are recommended to be located on the south side, where there is protection from the north wind with a fence or buildings.
- The weak point of the variety is the rhizome, so it is better not to plant Polka in areas with high humidity or near water. Also, one should not plant shrubs on the hills, where in the winter it blows away snow drifts, the soil is exposed. In summer, raspberries suffer from a lack of moisture.
Recommendations in which soil to plant Polka:
- The berry is unpretentious to the soil, but it is recommended to choose land with a small acidity index.
- Polka loves to be adjacent to currants, apple trees, cherries and blackberries. It is preferable to plant vegetables near the bushes. He does not like when sea buckthorn or grapes grow near.
Selection of seedlings
Ideal option: buy seedlings in special nurseries or on horticultural farms with an excellent reputation. Here the plants paste the data:
- variety;
- landing date;
- care instructions.
When choosing young berries, you must carefully examine them. In healthy plants, the shoots are flexible, the seedling is 1 cm thick, the bark is smooth and clean. The root should be slightly moist and not tangled. Several roots should extend from the central branch of the root.
Experienced gardeners are advised to purchase two-year-old shoots in containers. These seedlings have a developed rhizome and they take root in a new place without any problems.
A huge selection of young plants happens before the start of frost. At this time, it is too late to transplant the shrub into the ground. In order for the plant not to die before the cold, it is laid in the trenches. To do this, dig a hole with a depth of 15 cm with a slope on one side where the shoots fit. Then they are covered with soil and covered well with insulation. To repel and protect against small animals, the place is covered with spruce branches.
Landing: a step-by-step process
The step-by-step landing process looks like this:
- A few days before planting seedlings in the ground, prepare a place: dig the soil, remove the extra plantings, fertilize the soil with humus and factory fertilizers.
- Immediately before planting the plants in the ground, lower the rhizomes into the biostimulant liquid for 2 hours. For the prevention of rot in the substance, add Fundazole.
- Gardeners use a linear type of planting (a trench is dug up, seedlings are placed in it) and a bush type (in loose). With the linear version, raspberries are better lit, it is easy to care for and remove the berries. The depth of the pits should be at least 45 cm, width - 70 cm. It must be remembered that the bush grows rapidly.
- Sprinkle a little earth into the pit.
- Put a bush in it, gently spreading the roots. Seedlings from containers are placed with a lump of earth.
- Sprinkle the shoot with earth, leaving the base of the root open.
- To strengthen the base of the roots, cover the seedling near the ground with straw.
- Leaves at a height of 40 cm. Must be cut.
Caring for Raspberries Polka
Raspberries of this kind require special care, which must be done regularly. Otherwise, the fertility of the plant will be low.
Watering
The plant requires constant watering. Heat affects berries and productivity badly. On hot days, the fruits are baked, begin to dry, the greens fade. For good growth and fertility, soil moisture at a depth of 30 cm should be at least 75%.
With a decrease in humidity, plants are watered every 7 days. In early autumn (if there is no rainfall), it is required to water raspberries at the rate of 20 liters per bush.
If the humidity exceeds 80% - this is bad for raspberries of this variety. The water remaining in the hole blocks the access of oxygen to the root system, the leaves turn yellow. Do not water the bushes for a period of time and loosen the soil.
Types of watering:
- Sprinkling - water is sprayed from a hose or watering system. The option is advised to use in dry weather: watering irrigates the bush itself and increases air humidity. It is not recommended to do sprinkling during the ripening period.
- Furrow irrigation - in this case, the water is mixed with fertilizers. Before irrigation, grooves are dug through which fluid flows. After watering, the trenches burrow.
- Drip irrigation is the best watering option. In pipes laid along the bushes, holes are made through which water under pressure is supplied directly to the roots. Consequently, humidity always remains at the same level, which is why fertility increases by 35%. This type of irrigation provides for automated installation (conveniently in large areas).
Wet soil needs to be loosened to avoid crusting. In order not to touch the roots when loosening, it is required to perform the operation not deeply (about 7 cm).
If the landing site belongs to an area with low humidity, it is necessary to cover the ground with mulch. It retains moisture in the ground, preventing it from evaporating. Mostly covered with straw, onion husks.
Weeding
It is necessary to water the shrub regularly, nettles and other weeds pull the nutrients necessary for raspberries from the soil, obscure the sun. Weeding must be done carefully without damaging the root system. If young shoots of a plant appear between the bushes, they must be removed. Strong blocking of the plot is not desirable, as it negatively affects the yield.
Top dressing
For an optimal balance of nutrients, the bush needs top dressing.
How to determine what a plant lacks:
- the leaves began to turn yellow for no reason - not enough nitrogen;
- not the natural dark green color of the stems and leaves - phosphorus levels have decreased;
- rounded leaves and a dark border - a lack of potassium.
In the spring, during the growth period, raspberries are fed with urea (30 g per 1 sq. M). Cow dung or chicken droppings with water are used as top dressing (1:10 or 1:20, respectively).
Top dressing, which contains nitrogen, increases the acidity of the soil, Polka does not like this. To adjust the acidity, it is necessary to sprinkle ash on the soil.
Polka has a negative attitude towards chlorine. The presence of this substance can cause a disease such as chlorosis.
When the first berries appear, you can water the shrub with organic fertilizers - infusion of nettles and onion husks. Nettle should be finely chopped, put in a container with water and left for 7-10 days. Then strain the infusion and dilute with water 1:10. A composition of onion husks (0.5 kg per 10 l) is also being prepared.
Garter
This raspberry variety does not need a garter or extra support. It happens that a lot of berries appeared on the bush, then the stalk slopes to the ground. In this case, you can make a garter.
At a distance of 20 cm from the bush carefully, without damaging the root system, a column is driven in. The stalk is tied in several places so as not to damage the bark.
Some gardeners use a net for linear planting. Stakes are driven in on both sides of the strip and a wire or mesh is tied in several rows between them. As the shoots grow, they are fixed to the net.
Breeding
There are several options to propagate the culture:
- Seed - this species is acceptable for breeders, as the process takes a lot of time.
- Green cuttings - in June, young shoots are cut off (at an angle of 45 degrees). Then transplanted to a place prepared for seedlings. In two weeks, sprouts in moist soil will come to life. Closer to autumn, young shoots are transplanted into raspberries.
- Root cuttings - in September, the roots are dug up, cut into pieces (10 cm) and buried in moist soil. Cover with mulch and spruce branches. The place is covered with a film, which is removed in the spring after the emergence of shoots. The shoots are grown and transplanted into raspberries by autumn.
- Division of the bush - the bush is dug up with the root, divided into several elements and transplanted into separate pits. The tops of the stems are cut so that lateral branches appear.
Pruning and wintering
At the end of October, the entire aboveground part of raspberries is cut off (should remain 3 cm from the stem). This method will help protect the bushes from frost, beneficially affects the fertility of the plant, protects the culture from pests.
If you leave only young growth, removing old trunks, the yield will be lower (the bush will not develop evenly). The remaining shoots and hemp cover so that the culture does not freeze in frost.
In the spring, before the buds begin to bloom, it is necessary to remove frozen and broken stems. It is required to remove all excess branches (leave up to 9 pieces on one trunk). Before flowering begins, the tops of the bush (15 cm) are removed, so raspberries stop growing, which has a beneficial effect on productivity.
Harvesting
On a production scale, the crop is harvested with special scoops that capture the entire brush. In the garden, it is recommended to carefully cut the brush, and then remove the berry. So the fetus does not deform. The bush itself, from which the brush was cut, sends nutrients to the ripening of new berries.

Diseases and Pests
Since this raspberry variety is completely mowed before wintering, pests rarely bother plants. But in unfavorable soil, the root system may become ill in this variety.
Disease
- Root cancer - tumors form on the roots, the bush withers, and fertility decreases. Bacteria may appear in the soil or humus. For prevention, you should not grow raspberries in one place, you also need to disinfect the roots before planting. For treatment, it is necessary to cut off the tumor and treat the cut points with 1% solution of copper sulfate or completely dig out the plant.
- Verticillus wilting - the roots crack, the leaves turn yellow and fall, the berries become small. For treatment, treat the affected area with a 0.2% solution of Vitaros or Fundazole.
- Root rot - the greens at the roots become stained, the leaves turn brown, the roots rot. For treatment, you need to destroy the bushes, treat raspberries with a special solution of fungicide.
Pests:
- Chafer - to water plants with manganese or to pull out beetles manually.
- Raspberry mole - before the buds appear, spray the bushes with lime (1 kg per 10 l).
- Aphids - it is necessary to wash off insects under a stream of water.
Gardeners reviews
Natalia, 35 years old, amateur gardener, Chelyabinsk. Planted a variety on the advice of a friend. She didn’t do anything, only watered during a drought. In the first year I collected 4 buckets of harvest.
Svetlana, 62 years old, lives in a village, Moscow region. I love raspberries Polka - juicy and tasty! Grandchildren come, so they simply can not be torn from the bushes. All have enough and remains for jam.
Nikolai, 44, summer resident, Moscow. I do not like to mess around in the garden, but this berry does not require special care. Basically only watering and cut in the fall. But the yield in this situation is good. We pick berries after small frosts.
