More and more summer residents are choosing remontant raspberries for their plots. Its varieties produce a harvest already in the first year after planting. Polana raspberry was bred by Polish breeders, however, the plant feels great in the middle zone. The shrub has good productivity with minimal cost and care.
Characteristics of the variety
Polana is a raspberry with many straight shoots about 1.6 m high. The berries have the shape of a rounded cone with small drupes. There are small thorns on the branches. Raspberries branch well and form many shoots.
Polana raspberries produce medium-sized firm berries weighing up to 5 g. The color is bright red, which becomes darker as it ripens. Raspberry fruits have a sour taste, but with abundant sunlight they become sweeter. During the ripening period, a sour taste remains if by the end of summer there are fewer sunny days.
Four shoots are enough to form a bush. To increase productivity, their number is increased to forty.
Productivity of the variety
Polana raspberries ripen quite early. In the southern regions, the first harvest can be harvested at the end of July. For the northern territories, this date is shifted to mid-August.
Fruiting continues until mid-October. Fruit ripening occurs even when the temperature drops to +5°C. From one bush you can collect up to 4 kg of berries.
Landing rules
Polana raspberry prefers chernozem or sandy loam soil. Although the variety is resistant to winter cold, it is best suited for the middle zone.
It is recommended to plant seedlings in late autumn. For a raspberry garden, choose a sunny area, protected from wind and dampness. Raspberries require moisture, but stagnation will cause the death of seedlings.
Planting raspberry polana takes place in several stages:
- Trenches with a width and height of 0.5 m are dug. 0.8 m is left between the bushes, and from 1 to 2 m between the rows. Raspberries can be planted in holes 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). The top layer becomes light fertile soil.
- No more than 4 shoots are left on each plant so as not to overload it.
- When planting, the root collar of the raspberry polana should remain near the surface of the soil. In loose soil, the root collar is left 5 cm above the soil level.
- The final step is watering the raspberries. Each bush will require one bucket of water.
- Raspberries are sprinkled with mulch (peat or compost).
Features of care
To obtain high yields, it is enough to follow simple rules for planting and caring for polana raspberries.The set of operations is standard for this type of shrub: pruning, watering, fertilizing.
Pruning rules
Remontant varieties of raspberries bear fruit on last year's and new branches. The first harvest requires a significant influx of nutrients. Therefore, this year the shoots develop more slowly and bear fruit later. Timely pruning of raspberries helps to correct the situation.
The repeated procedure is performed in the spring, when broken and frozen shoots are eliminated. Dry branches can be removed in summer. Young shoots are removed from the roots of the Polana raspberry, otherwise it will take nutrients for itself.
Up to 10 polana raspberry shoots are left per square meter. The healthiest and strongest ones are chosen.
Watering rules
Polana raspberries require regular irrigation:
- the soil should be 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 formation of fruits;
- If there is little precipitation in the fall, winter top-up 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 raspberries. Under bushes, the loosening depth is up to 7 cm, and between rows - no more than 12 cm.
Mulching helps prevent the soil from freezing in winter.In the summer, an additional layer prevents it from overheating. Suitable for these purposes are straw, peat, sawdust, and compost, which rot and become a source of nutrients. In spring, mulch is mixed with the soil.
Raspberry feeding
The influx of nutrients helps increase the yield of raspberry polana. At the beginning of the season, fertilizing is carried out before the growing season. Mullein or other organic fertilizer is suitable for this. It is diluted with water, maintaining 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 raspberry bush. The Polana raspberry variety requires feeding three times throughout the year.
Mineral fertilizers help strengthen the shoots. For raspberries, superphosphate and potassium sulfate are chosen. One square meter requires 50 g of each type of fertilizer.
During the growth period, Polana raspberries experience a lack of nitrogen. You can feed the plants in early spring.
Protection from diseases and pests
Like any shrub, raspberry Polana experiences the negative effects of 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 over time become black with a white border;
- spots and cracks on the shoots.
For the treatment and prevention of septoria in raspberries, a set of measures is used:
- before budding, the bushes are treated with a 1% solution of Bordeaux mixture;
- In the summer, before and after flowering, the shoots are sprayed with a solution of copper oxychloride.
Purple spots
If purple spots appear on the cuttings of raspberry leaves, this is the first sign of plant disease.If no action is taken, the lesion will completely cover the stem.
Treatment for purple raspberry spots includes the following treatments:
- before buds open - Bordeaux mixture or Rubigan solution;
- in the summer - copper oxychloride.
To prevent the disease, free space is left between the raspberry bushes and the area is ventilated. Overwatering 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 get rid of them. For 10 liters of water, 30 g of this substance is required. Treatment is carried out before budding begins. The procedure is repeated after harvesting.
Reviews from gardeners
Conclusion
Polana is suitable for the middle zone, although it tolerates low temperatures well. A distinctive feature of the variety is its early fruiting compared to other types of remontant raspberries. As can be seen from the reviews of gardeners, raspberries require only standard care.
