Description and characteristics of Polana raspberries
Raspberries of this variety are characterized by compact, medium-sized bushes, the height of which is 1.5 meters. The plant is distinguished by straight, fairly powerful shoots that can withstand the load of the crop. The branches are covered with small thorns.
Polana has high shoot-forming abilities. It is characterized by alternate, petiolate leaves that have a complex structure. They have a rich green color above and whitish below. The flowers are small in size and white in color.
Raspberries of this variety are characterized by juicy sweet and sour berries that have a pronounced aroma. On average, the fruits weigh 5-6 grams. The berries are distinguished by their rich dark crimson hue and conical shape.
Polana differs from other raspberry varieties in its early onset of fruiting. The berries do not fall off as they ripen. The yield from one bush is 4 kilograms of fruit. The first fruits can be obtained at the end of July or at the beginning of August. In this case, fruiting lasts until mid-October.
Advantages and disadvantages
The main advantages of the variety include the following:
- resistance of roots to frost;
- high yield parameters;
- rapid fruit ripening;
- resistance of ripe fruits to falling from the bushes;
- long fruiting;
- ease of transportation;
- resistance to diseases and pests;
- ease of reproduction.
At the same time, culture also has some disadvantages:
- poor resistance of branches to frost;
- risk of drying out;
- rapid growth of shoots.
How to grow crops correctly
In order for a crop to grow normally and bear fruit abundantly, it needs to be provided with high-quality care.
Landing dates
Most often, remontant raspberries are planted in the fall. This is recommended to be done from late September to early October.At this time, the soil retains a sufficient amount of moisture, and the air temperature remains quite high. Thanks to this, the seedlings have time to adapt to a new place. It is also permissible to plant raspberries in the spring. However, it is recommended to do this before the sap flow begins.
Where and how to plant?
Raspberries of this variety require a lot of sunlight. With strong shading, the yield is significantly reduced and the taste of the fruit deteriorates.
Polana does not require special conditions. It can grow in different types of soil. However, drained soddy-podzolic non-acidic soils are most suitable for the crop. The quality and quantity of fruits depend on the fertility of the soil.
To plant raspberries, it is recommended to do the following:
- Dig longitudinal trenches measuring 50 centimeters. The distance between plants is recommended to be 0.8-1 meter. The row spacing should be 1.5-2 meters.
- Fill the holes one third with fertile soil, mixing it with fertilizers. For 1 square meter of trench use 10 kilograms of humus, 100 grams of potassium sulfate, 200 grams of superphosphate.
- Place the seedlings in the trenches and carefully straighten their roots. Before this, it is recommended to lower them into a clay mash.
- Sprinkle the trenches, placing the root collar 3-5 centimeters above the soil surface.
- Water the plants. For each bush you should use 5-7 liters of water. After this, the soil needs to be loosened and covered with a mulch layer.
Recommendations for caring for the variety
In order for the bushes to develop normally and bear fruit abundantly, they require comprehensive care.
Watering rules
Raspberry Polana is considered a moisture-loving variety, but it does not tolerate stagnant moisture. During the growing season and fruit ripening, the crop requires good watering. This affects the quality and quantity of fruits at the harvest stage. It is permissible to water raspberries directly in trenches or use the sprinkling method. Under 1 bush you need to pour 2-3 buckets of water.
Feeding and fertilizers
The crop is not too demanding on fertilizers. However, proper application of fertilizing has a positive effect on its development. The bushes should be fed for the first time when the shoots grow to 30-35 centimeters.
In spring, it is recommended to use organic substances - manure, ash or bird droppings. In autumn it is worth using only superphosphates. The soil also needs to be systematically loosened.
Trimming, covering, garter
At the end of the fruiting season, the bushes should be completely pruned. In this case, the shoots should have a height of 8-10 centimeters. This will help protect the crop from pathologies and parasites and survive the winter. Raspberries need to be pruned before the first frost.
Despite the powerful shoots, it is recommended to tie up the bushes. In strong winds the shoots may break. In addition, the garter makes harvesting much easier.
Raspberry Polana is considered a very frost-resistant plant. Therefore, before wintering it is enough to prune the bush correctly. Snow cover provides additional protection.
Protecting raspberries from diseases and pests
The main diseases of this raspberry variety include:
- Botrytis or gray rot is a fungal infection that is accompanied by the formation of dark spots on foliage and berries.To cope with the disease, the affected fragments must be removed and burned. To prevent pathology in the spring and after harvest, the bushes must be treated with Bordeaux mixture.
- Dwarfism or overgrowth - the disease manifests itself in the form of rapid growth of small shoots that do not bear fruit. In this case, the affected seedlings must be uprooted and burned.
- Anthracnose - this pathology is fungal in nature and leads to crop loss. To prevent the disease in the spring, it is recommended to use copper oxychloride.
Sometimes raspberries encounter dangerous pests - aphids, spider mites, weevils, raspberry beetles. A solution of karbofos helps to cope with parasites. It is recommended to use 30 grams of this product per 10 liters of water. It is necessary to treat the bushes before the formation of buds. The second time raspberries are sprayed after harvesting.
Harvest and storage
The plant bears fruit from August to October. At the same time, even ripe fruits do not fall off the bushes. It is recommended to collect only dry fruits. It is best to do this in the morning or evening. Berries must be placed in small containers. They can keep in the refrigerator for a week. To preserve the harvest for a long time, raspberries can be frozen.
Polana raspberry is a popular garden crop characterized by high yield. In order for a plant to develop normally, it needs to be provided with complete and high-quality care.
