More and more summer residents are choosing remontant raspberries for their plots. Its varieties give a harvest in the first year after planting. Polana raspberry was bred by Polish breeders, however, the plant thrives in the middle lane. The shrub has good yields with minimal cost and maintenance.
Characteristics of the variety
Polana is a raspberry with many straight shoots about 1.6 m high. The berries are in the shape of a rounded cone with a small drupe. There are small thorns on the branches. Raspberries branch well and form many shoots.
Raspberry Polana gives hard, medium-sized berries weighing up to 5 g. The color is bright red, which becomes darker by the time of ripening. Raspberries have a sour taste and become sweeter with abundant sunlight. A sour taste remains for the ripening period, if by the end of summer there are fewer sunny days.
Four shoots are enough to form a bush. To increase the yield, their number is increased to forty.
Variety yield
Polan raspberries ripen early enough. In the southern regions, the first harvest can be taken at the end of July. For the northern territories, this period is shifted to mid-August.
Fruiting continues until mid-October. Fruit ripening occurs even when the temperature drops to + 5 ° C. Up to 4 kg of berries can be harvested from one bush.
Landing rules
Polana raspberry prefers black earth or sandy loam soil. Although the variety is resistant to winter cold, it is best suited for the middle lane.
It is recommended to plant seedlings in late autumn. A sunny area, protected from wind and dampness, is chosen for the raspberry tree. Raspberries need moisture, but stagnation will cause seedlings to die.
Planting raspberry polana takes place in several stages:
- Trenches with a width and height of 0.5 m are dug out. 0.8 m is left between the bushes, and between the rows - from 1 to 2 m.Raspberries can be planted in pits with a diameter and depth of up to 35 cm.
- The trenches are filled with humus (16 kg), lime (0.3 kg) and ash (0.5 kg). Light fertile soil becomes the top layer.
- No more than 4 shoots are left on each plant so as not to overload it.
- When planting, the root collar of the polana raspberry should remain at the surface of the soil. In loose soil, the root collar is left 5 cm above the soil level.
- The final step is to water the polan raspberries. Each bush will require one bucket of water.
- Raspberries are sprinkled with mulch (peat or compost).
Care features
To obtain a high yield, it is enough to follow the simple rules of planting and caring for polana raspberries. The set of operations is standard for this type of shrub: pruning, watering, feeding.
Pruning rules
Repaired raspberry varieties bear fruit on last year's and new branches. The first harvest requires a significant supply of nutrients. Therefore, in the current year, shoots develop more slowly and bear fruit later. Timely pruning of polana raspberries helps to correct the situation.
A second procedure is performed in the spring, when broken and frozen shoots are eliminated. Dry branches can be removed in summer. Young growth is removed from the roots of the raspberry polana, otherwise it will take up nutrients for itself.
Up to 10 shoots of raspberry polan are left per square meter. The healthiest and strongest of them are chosen.
Watering rules
Polana raspberries require regular irrigation:
- the soil should get wet by 0.4 m;
- the frequency of watering is determined by the climatic conditions of the region;
- the need for moisture increases during flowering and further fruit formation;
- if there is little rainfall in the fall, a sub-winter gravy is required.
Loosening and mulching
To increase the moisture permeability of the soil, it is loosened. At the beginning of the year, the operation is performed before the growing season of raspberry polana. Under the bushes, the depth of loosening is up to 7 cm, and between the rows - no more than 12 cm.
Mulching helps to avoid freezing of the soil in winter. In the summertime, an additional layer prevents it from overheating. For these purposes, straw, peat, sawdust, compost are suitable, which rot and become a source of nutrients. In the spring, the mulch is mixed with the soil.
Feeding raspberries
The influx of nutrients helps to increase the yield of polana raspberries. At the beginning of the season, feeding is carried out before the growing season. For this, a mullein or other organic fertilizer is suitable. It is diluted with water, observing a ratio of 1 to 10. If chicken manure is used, then the ratio is 1 to 20.
Up to 10 liters of solution are required per square meter of raspberries. The polana raspberry variety requires feeding three times a year.
Mineral fertilizers help to strengthen the shoots. For raspberries, superphosphate and potassium sulfate are chosen. One square meter requires 50 g of each type of fertilizer.
During the period of growth, raspberry polana lacks nitrogen. You can feed the plants in early spring.
Protection against diseases and pests
Like any shrub, polana raspberry is negatively affected by diseases and pests. Simple measures available to every gardener will help protect the plant.
Septoria disease
Septoria has the following characteristics:
- round brown spots on the leaves, which eventually turn black with a white border;
- spots and cracks on the shoots.
For the treatment and prevention of septoria in raspberry polan, a set of measures is used:
- before budding, the bushes are treated with a 1% solution of Bordeaux liquid;
- in summer, before and after flowering, shoots are sprayed with a solution of copper oxychloride.
Purple spots
If purple spots appear on the cutting of raspberry leaves, then this is the first sign of plant disease. If you do not take action, then the lesion completely covers the stem.
Treatment for purple polan raspberry stains includes the following treatments:
- before bud break - Bordeaux liquid or Rubigan solution;
- in the summer - with copper chloride.
To prevent the disease, a free space is left between the polan raspberry bushes and the area is ventilated. Over-watering should also be avoided.
Pest control
The most common pests of varietal raspberries are aphids, raspberry beetles, spider mites, and weevils. A solution of karbofos helps to get rid of them. 10 liters of water requires 30 g of this substance. Processing is carried out before the beginning of budding. The procedure is repeated after harvest.
Gardeners reviews
Conclusion
Polana is suitable for the middle zone, although it also tolerates low temperatures well. A distinctive feature of the variety is early fruiting in comparison with other types of remontant raspberries. As you can see from the reviews of gardeners, raspberry polana requires only standard care.
