Raspberry Amira: characteristics, features of cultivation
Raspberry Amira is one of the leading repair varieties. It ripens quickly, characterized by large and compact red berries, which are easily removed and well stored. In the article you will find a description of the characteristics of the variety, its advantages, as well as the characteristics of cultivation.
Repairing raspberry varieties have gained popularity among gardeners due to the ability to harvest several times a year and high resistance to disease. Most of them mature well in short summers.
Did you know? Raspberry's health benefits include improving digestion, boosting the immune system, ensuring heart health, preventing cancer, improving memory, maintaining healthy bones, caring for your skin, and improving your eyesight.
Amira is one of the best European varieties bred in Italy. It is obtained by crossing varieties Tulamin and Polka in the Italian nursery Berry Plant. Breeders set themselves the task of obtaining high-yielding large-fruited raspberries that can grow in the northern regions. Both parent varieties are well known.
Polka is a very productive variety with large sweet berries. And Tulamin is not only considered the standard of raspberry flavor, but also able to grow in the northern regions. The subsidiary variety has all the positive characteristics of the parental varieties.
Fruits Amir 2 times a year: in July and early fall. Large, sweet berries can be stored for 3-4 days longer than fruits of other varieties. They are great for jams, jellies and fresh drinks.
The bushes are characterized by great growth power, excellent productivity and good yield. The bushes are also characterized by compactness. They are not too tall with a height of up to 2 m, but quite thick. Therefore, the use of trellis as a support is a must. V-shaped support is preferred. The shoots are too spiky and this must be taken into account when harvesting.
Advantages and disadvantages
- Grade advantages:
- excellent taste;
- accuracy of berry placement;
- high productivity;
- the possibility of harvesting 2 weeks earlier than other varieties;
- good adaptation to a cool climate;
- high transportable properties;
- high winter hardiness.
Drought resistance, frost resistance
It withstands freezing up to -26 ° C. Therefore, it is considered quite frost-resistant. And of course, like all repair varieties, Amira is drought tolerant.
Productivity and fruiting
One bush per year forms up to 7 shoots. The summer crop is formed on the shoots of the second year of growth, and the autumn crop on those that appeared in the current year. The first wave of the crop ripens a week before Tulamin, and the second - 3-4 weeks before the late varieties. In practice, this means that the farmer will make a profit at the moment when the berries of the other varieties are not yet available, and, consequently, the prices will be as high as possible.
The variety is mid-early. Keep in mind that in colder regions fruiting will shift towards the end of July, and in the southern regions towards the beginning. In July, up to 80% of the total crop, which you remove from Amira for the season.From one bush you can collect about 3 kg of berries. The mass of one berry is 6–8 g. They are perfectly separated from the stem and have a dense texture. Therefore, transporting them is quite easy. The shape of the berries is beautiful, conical. Color is bright red. They differ in that they are almost not susceptible to shedding from the bush.
Planting raspberries is possible both by dividing the root system of the bush along with part of the shoots, and by planting individual shoots or seedlings. The variety can grow in open ground and in a greenhouse.. In closed ground, you can also use containers for planting. Plant shoots at a distance of at least 40 cm from each other. The distance between the rows should be about 1 m.
Important! Plant black or purple raspberry varieties at least 100 m from red or yellow varieties to avoid mutual pollination.
Planting is carried out in the spring in April or May after the spring frosts end. Autumn planting is carried out in September, until the air temperature drops below + 12 ° C. But in the northern regions, it is preferable to do this in the spring, so as not to expose plants with a weak root system to low temperatures.
Choosing the right place
For raspberries, select a well-drained sunny area, on which water does not stagnate. Prepare the soil by mixing compost or other organic matter with it in equal proportions. This is especially important if the site is not well drained. Dig the soil to a depth of 40 cm, removing weeds and breaking up large clods of earth.
Selection and preparation of planting material
For planting, direct shoots with a powerful fibrous root system without signs of disease are suitable. The length of the stem should be at least 40-50 cm. Thickness - 0.5-0.8 cm. Under the bark, if it is scrubbed with a finger there should be a green layer - a sign that this is a living seedling. The roots of the plant are fibrous. They consist of several denser roots and many smaller ones. They should not have growths and they should not be broken off.
Landing is carried out in rows in trenches or holes. Since Amira reaches a height of 2 m, they must install a trellis. Support poles are buried in the ground to a depth of 0.8 m, and at least 1.5 m must remain above the surface in order to tie up the bushes. Position the garter wire so that the structure is the letter V on its side.
Did you know? Russia is the leading producer of raspberries in the world. It accounts for about half of the world production of these berries. Other major manufacturers are the United States, Poland and Mexico.
- Trim the plant for very long or broken roots.
- Cut the top of the shoot 10-15 cm.
- Prepare holes up to 40 cm deep or a landing trench. The distance between the holes should be about 40–45 cm. The width of the hole is greater than the root ball.
- Set the roots of the shoot in the center of the hole and straighten them.
- Fill with soil mixed with compost.
- Gently squeeze the soil around the plant. Compaction is necessary to ensure good contact of the root system with the ground.
- Carefully water the bush.
- Mulch the root zone with pine needles, wood chips or straw to preserve moisture and prevent weed growth.
If planting will be carried out in containers, then the plant needs to be deepened to the same depth at which it grew before. Weeds compete with bushes for water, space and nutrients. Control their growth by occasional weeping or prevent germination with mulch.
After planting, the bushes should be watered well during the growing season. The best type of watering is dripin which water is supplied very slowly and moistens the earth well. Keep the soil moist but not waterlogged.If you are watering with air sprinklers, water early in the morning so that the foliage has time to dry before the bright daylight appears.
In the spring, before the leaves appear, apply granular fertilizer. The best option is top dressing with balanced formulations. This fertilizer consists of nitrogen, phosphorus and potassium taken in equal percentages. For example, 10-10-10. Fertilizer can then be applied every 2 weeks following the instructions on the package.
Pruning raspberries is also a necessary event. When the shoots of the second year of development have bred, they are removed, since there will be no more berries on them. Pruning is carried out in winter when the bushes are at rest. Also remove all weak shoots, with a very small thickness.
Do not cut the shoots of the first year unless dead, damaged, or diseased wood is removed. Every spring, choose the 5 or 6 most energetic new shoots and shorten them to 90 cm in height.
Important! If the soil is clay, then in it no more than 2% of organic matter. Therefore, you definitely need to fertilize such soil regularly.
Tying is necessary with a large crop weight. Therefore, gardeners must install trellises and tie shoots to them. This prevents raspberries from shedding in strong winds and makes plant care easier.
Harvesting and storage
Raspberries cannot be stored for very long. At room temperature - no more than 3 days. In the refrigerator - no more than a week. Therefore, it is extremely important to harvest and process on time. Ripe berries have a uniform bright red color, easily detach from the stalk and acquire a rich, sour-sweet raspberry flavor. Collect them dry. the weather
Since the safety is highly dependent on the temperature of the berries, the collection is prescribed in the early morning. Berries are removed immediately in plastic containers or other containers. If you plan to ship to the store, then collect immediately in the container in which they will be transported. Collect dense fruits without damage, mold or insects.Keep the berries in the refrigerator for about a week. During this time, they need to be eaten fresh or processed. The dessert taste of Amira berries is good in any workpiece. You can also freeze part of the crop for later winter use.
In autumn, a raspberry patch is freed from the remnants of foliage. Repairing varieties, including Amira, do not need shelter for shoots for the winter. The variety withstands frosts down to -26 ° C. But if you expect the temperature to be lower or the frost longer, then simply cover the bushes with agrofiber. As soon as the threat of frost is over, remove the agrofibre so that the bushes do not overheat and start vegetation ahead of schedule.
The most valuable part of raspberries is the root. Unlike shoots, it can exist for more than 10 years. In order to prevent its damage by frost, you can put a layer of mulch in the raspberry. This is done after the soil freezes. Mulch will act as an insulating layer. They clean it as soon as warm weather sets in to prevent the roots from aging.
Did you know? In Europe, raspberries have been growing for quite some time. But in America it was not. It is believed that she got there along with the prehistoric tribes that crossed the Bering Strait.
The main methods of propagation of raspberries are three:
- By dividing the bush. The root of the plant is creeping. It forms several shoots of the aerial parts. You can always separate part of the shoots along with part of the root and plant them in a new place as a new bush.
- A creeping root can form an shoot away from the main bush. Such an offspring with a part of the root must be planted separately. This is the most popular way to bookmark a new bush.
- When the shoots of the first year of development are shortened, then you have the tops. If they are planted in a container with fertile soil, then they form the roots.This method of reproduction is called seedlings.
Diseases and Pests
Like other plants, raspberries can hurt. Location, weather and proper care are factors that influence the likelihood of illness. Therefore, if you choose the right site, the water does not stagnate at the roots and watering occurs regularly, then your plants will not hurt. Amira is a disease resistant variety.
Treatment from pests is carried out after their identification. To do this, spray with special insecticides. Often choose drugs with a wide spectrum of action. They destroy most pests at the same time.
The main pests of raspberries:
- Aphids - tiny insects feeding on plant juices. They accumulate on stems and leaves in large quantities. Copper dew secreted by aphids serves as a medium for the reproduction of sooty fungi. Kill insects by spraying the shoots with a solution of insecticidal soap.
- Raspberry beetle damages the buds and can thus destroy the future crop. But it is not terrible for the repairing varieties due to the fact that the development cycle of the beetle falls at an earlier time and coincides with the classical varieties. And later repairing ones blooming are not subject to attacks of this insect.
The acquisition and landing of Amira is commercially viable. Convenient fruiting periods and the possibility of selling berries at higher prices due to their appearance up to the main mass of raspberries are a powerful argument in favor of this variety. The main thing is to choose the right site and put your knowledge into practice in order to get a high yield.
Amira is a registered trademark. In reality, the variety is called BP1 (from the name of the breeding company - Italian kennel BerryPlant). Amira's parents include such well-known varieties as Polka and Tulamin. But unlike the Shelf, the berry is bright red and practically does not darken after collection . The taste is excellent. In the conditions of the Vinnitsa region it ripens from the beginning of August (on annual shoots). Next year you can get an early harvest in June from the bottom of the shoot.
