Raspberry variety Sun: advantages and disadvantages, yield indicators
Raspberries belongs to the category of the most common types of berries that are grown in large and small suburban areas, and the Sun variety is rightfully considered one of the best varieties of this culture. Its beautiful fruits have excellent taste and ripen in the first half of summer, and even a beginner gardener can cope with the agrotechnics of growing a bush. A detailed description, the pros and cons of Raspberry Sun, as well as the features of planting, growing and propagating bushes of this variety are listed below in the article.
This variety of berries was obtained in the 90s of the XX century. as a result of crossing raspberries Novosti Kuzmina and Kostinobrodskaya. An employee of the support point of the All-Russian Selection and Technological Institute of Horticulture and Nursery, a Russian breeder I.V. Kazakov worked on creating a new variety. He wanted to receive early ripe and unpretentious raspberry in leaving, characterized by high productivity. In 1992, the Sun variety was introduced into the State Register and began to actively gain popularity among gardeners.
Did you know? Aromatic herbal tea can be made from raspberry leaves. To do this, they are ground in hands until the juice is released, and then dried in the oven.
Description and characteristics of the variety
Raspberry bushes The sun has a number of characteristic features and is often not only a source of sweet berries, but also an original decorative decoration of the site. A brief description of the variety is presented below:
- Bushes can reach a height of 2-3 m. New shoots form poorly, so the plants are not sprawling and look rather compact in width.
- Raspberry stalks of this variety are powerful and straight, grow quickly up. Their tops have an elegant bend that gives the bushes a decorative value.
- Outside, young branches are covered with green bark, on which there is a thin layer of wax coating. Subsequently, the shoot surface acquires a brown or reddish hue.
- Raspberry leaves The sun has a wrinkled surface and a rich green color. There are very few thorns on the bush, and the branches are completely covered with small hairs.
- Ripe berries are large in size and in the shape of a blunt cone, painted in a bright purple color.

Advantages and disadvantages
Raspberry Sun has gained immense popularity among gardeners due to its many positive qualities.
- The main advantages of this variety are:
- high productivity;
- early ripening of berries;
- good winter hardiness;
- good taste and attractive presentation of raspberries;
- universal use of fruits;
- excellent crop mobility;
- high content of vitamin C in the pulp of fruits;
- ease of picking berries due to the small number of thorns;
- good immunity against fungal infections and raspberry pests;
- unpretentiousness in leaving.
Despite the many advantages, the variety Sun is not without some disadvantages.
- These include:
- exactingness to watering;
- increased susceptibility to cold drafts;
- not strong root system.
Drought resistance, frost resistance
Raspberry Sunny needs regular watering, so it does not belong to drought tolerant varieties.
Important! With insufficient moisture in the soil, the yield of the bush is significantly reduced, and the berries are reduced in size and lose their sugar content.
Raspberry Sun is recommended to be grown in areas with a temperate and continental climate. The variety is characterized by good winter hardiness and successfully tolerates frosts up to –25 ° C without shelter, but only if there is sufficient snow cover. In regions with more severe winters, as well as in severe frosts and lack of snow, additional bushes must be covered so that they do not freeze.

Productivity and fruiting
One of the main advantages of raspberries the Sun is a large number of ripe berries on the bushes and the relatively early ripening.
The main characteristics of the yield and fruiting of this crop are listed below:
- fruit ripening lasts from the second half of June to the beginning of July;
- the bush is not remontant, bears fruit only 1 time per season;
- the yield of the variety is 1.5 kg of raspberries from each bush or about 87–90 kg / ha.
Fresh raspberries of the Sun variety can be frozen, and berries can also be used to make compotes, juices and jams.
Growing raspberries The sun begins with the purchase of planting material and its planting on the site. Bushes of this variety react negatively to cold drafts, so the place for planting must meet certain requirements and provide plants with the most comfortable conditions for growth. When buying seedlings, you need to be able to choose high-quality specimens and properly prepare them, and then perform planting, observing a simple sequence of actions. About all this - later in the article.

Planting raspberries is recommended to take into account the climatic characteristics of a particular region. This procedure must be performed at an appropriate time so that the young bush does not die, and its roots are well established in a new place.
Variety Sun can be planted in such periods:
- from late March to early April - in regions with cold winters, bushes are planted immediately after thawing the soil, before buds open, so that they can take root and begin to develop actively before sap flow;
- from late September to early October - in the southern regions with a moderately cold winter, planting is performed until the leaf fall is completed, so that the raspberries take root before the onset of frost and do not die from frost.
Choosing the right place
Raspberry bushes The sun has a superficial root system, so they need to be carefully selected a suitable place for planting. The plot for growing this crop must meet the following requirements:
- light and nutritious soil of neutral acidity - Loose loamy soil is best suited for bush roots;
- free access to sunlight - in the shade, plants grow worse and are more often affected by diseases, and berries become more acidic;
- lack of cold air streams - beneficially affects the growth rate of young seedlings and the number of fruits;
- suitable predecessors - Raspberries are recommended to be planted after currants, chokeberries, legumes or gooseberries, and strawberries, potatoes and tomatoes are bad predecessors for this crop;
- groundwater depth - at least 1.5 m, this variety needs regular moistening of the soil, but with an excess of water, the roots of the plants will begin to rot.
To prepare the site, perform the following actions:
- clear the soil of weeds and plant debris;
- dig the soil to a depth of 15 cm with the addition of 10 kg of humus or compost and a handful of wood ash for every 1 m²;
- mark the rows, positioning them at a distance of about 2 m from each other, and leave at least 1 m distance between adjacent holes in each row;
- the depth of each landing pit or trench should be up to 40 cm, and the width should be about 30 cm.
Prepared planting recesses can be covered with a film and left until planting, so that the earth has time to settle in them, and the fertilizer applied has dissolved well.
Important! Wells or trenches for seedlings begin to dig at least 3 weeks before planting.
Selection and preparation of planting material
For the successful rooting of raspberries on the site and its further abundant fruiting, it is important to choose a quality planting material. It is recommended to buy seedlings only from trusted sellers or in special nurseries - This will guarantee the acquisition of a healthy specimen that meets all varietal characteristics.
Signs of a quality raspberry seedling Sun are:
- developed and whole root system, consisting of elastic and healthy roots;
- the height of the seedling is about 30-50 cm with a stem diameter of 6-7 mm;
- no more than 4 lateral shoots, each of which is characterized by moderate flexibility;
- smooth and smooth bark of a bush, without cracks and growths;
- lack of evidence of disease or pest damage.
Immediately before planting, it is recommended to prune the young raspberry bush to a height of 40 cm and shorten its roots so that their length does not exceed 8 cm
The procedure for planting raspberry seedlings The sun is not particularly difficult, so even a beginner gardener can perform it. You can plant bushes in separate holes, as well as in trenches located on the site, according to the above scheme. The second method is used more often, and the reviews of experienced gardeners indicate that it increases the yield of the crop, and also helps to get a beautiful green hedge from the bushes.
Did you know? Bees collecting pollen from raspberry flowers increase the yield of this crop by 60–100%.
A step-by-step algorithm for planting raspberries The sun is presented below:
- Place the prepared seedling in the recess so that its roots are at a depth of 7 cm from the soil surface.
- Carefully straighten the roots inside the landing pit or trench. Sprinkle the seedling with loose fertile soil, leaving the root neck at a height of 1-2 cm from the soil surface.
- Carefully compact the ground around the trunk with your hands so that the seedling is better held in the ground and does not bend.
- Water each plant with plenty of water to moisten the soil well.
- After completely absorbing the liquid, mulch the earth around the bush with dry straw, forming a layer about 8 cm thick.
Raspberry The sun does not require specific care, therefore, for successful growth of bushes and high yields, it is enough to regularly water the plantings, periodically apply fertilizers and perform routine pruning of shoots.
Did you know? Due to the fact that the raspberry flower is lowered down, the bees can collect nectar from it even during light rain, being under a canopy of petals.
The main features of caring for plants of this variety are listed below:
- water the bushes need to be plentiful and as neededso that the soil around the plants is always moderately moist - raspberries need the most water during the formation and ripening of berries, but it is recommended to irrigate the beds until mid-autumn;
- after each watering you need remove all weeds around plantswhile performing surface loosening of the earth;
- so that the earth on the beds with raspberries remains wet and loose longer mulch with hay or sawdust;
- in early March, before the start of sap flow cut damaged, weakened and growing branches inside the bush, and shorten all healthy shoots to the first kidney;
- thinning pruning at the end of Mayleaving no more than 10 strong shoots on each bush - this will help get rid of excessive thickening and facilitate the access of sunlight to all branches and fruits;
- in the fall, crop shoots should be cut off at the base, as well as remove branches damaged by diseases and pests;
- to ensure uniform ripening of the crop and facilitate its collection, bushes are tied to trellis installed along the rows - for this, vertical supports are driven into the ground at a small distance from each other, and rows of wire are horizontally pulled between them;
- early spring raspberries fertilize nitrogen-containing compounds to stimulate the growth of shoots and leaves - about 12 g of ammonium nitrate and 10 g of urea dissolved in 10 l of water are consumed per 1 m²;
- for the formation and uniform ripening of berries at the beginning of June, a mixture of 10 l of water, 60 g of superphosphate and 40 g of wood ash is introduced under each bush - the indicated amount of nutrient solution is sufficient to process 1 m² of beds;
- at mid-October, plants are fed with compost or chicken droppingsdiluted in water in a ratio of 1:20.
Raspberry bushes Sunny tolerate winter well in the presence of a stable snow cover, but for effective protection of plants from frost, a number of preparatory steps are necessary. They begin to execute in the middle of autumn, while the stems of the bush still remain flexible.
Features of preparing raspberries of this variety for winter are listed below:
- in mid-October to implement winter bush wateringmoisturizing the earth around them to a depth of 20-30 cm, so that the roots are well saturated with moisture and better wintered;
- after completion of leaf fall remove all plant debris and fallen leaves - spores of the fungus and pest larvae can winter in them;
- cover the ground around the plants with a layer of mulch from humus, dry straw or peat, to protect the roots of the bush from freezing in the absence of dense snow cover;
- in the second half of October plant branches bend to the ground and fix them in such a position that they are completely covered with snow and not freeze;
- in areas with frosts below –25 ° C or in the absence of dense snow cover raspberry shoots are covered with coniferous branches or a thick layer of dry straw.
If raspberries are already growing on the site, then you can increase its number by propagating existing bushes. There are several ways to carry out this procedure:
- Propagation by root cuttings. This method of reproduction helps to save the bush, the stem of which has received damage. To do this, dig the soil at a distance of about 40 cm from the parent plant and carefully extract the subordinate root along with the branches. After that, each root is cut into pieces of 8-10 cm so that each of them has at least 1 kidney. The resulting cuttings are horizontally stacked one after another in small grooves, sprinkled with soil and regularly watered until green shoots appear.
- Bush division. This method consists in dividing the overgrown parental bush into several daughter plants and is used in early spring before the sap flow begins. In this case, the mother bush is dug out of the ground and its roots are divided into 2-3 parts so that each of them has at least 3 strong shoots. Subsidiary plants are planted independently, using the standard raspberry planting algorithm.
- Using green root layers. For this procedure, choose a one-year-old shoot starting from the root with a thickness of about 1 cm and bend it to the ground. The lower part of the appendix is fixed in this position with the help of pins and dug up with earth, and the top is tied to a vertical support. The shoot section sprinkled with soil is regularly watered, and when it takes root, they dig a young plant and plant it separately. This method of reproduction is carried out in late summer or early fall.
Diseases and Pests
The Sun variety has good immunity to diseases and pests, so raspberry bushes are rarely affected by them. But in violation of growing conditions or errors in care, problems may arise that require an immediate reaction from the gardener.
Important! During flowering, raspberry bushes can not be treated with chemicals for diseases and pests, since these funds cause the death of pollinating insects.
Raspberries The sun can be threatened by such infections and insects:
- Aphid. These small insects live at the ends of young raspberry shoots and breed well in shady places. Signs of their appearance are twisted leaves, slower growth of the bush, deformation of the branches and drying of the fruit. “Inta-Vir” is used against the pest, spraying them with raspberries according to the instructions.
- Gall shoot shooter. The insect lays eggs in cracks on the bark of raspberry branches, and the hatched larvae live under the bark and feed on the flesh of the shoots. The branches of the affected bush are covered with cone-shaped growths, and then dry together with leaves and berries. To get rid of this pest, you need to cut and destroy all infected areas, as well as dig the soil around the plant. After this, the plantings are treated with Karbofos.
- Purple spotting (didimela). Infection begins with the appearance on the stem of oval spots of lilac color. Subsequently, they spread to the entire surface of the bush, and their color becomes brown, small tubercles with spores are visible on the surface of the spots. The green part of the bush dries, and the plant dies. To treat infection, all affected areas must be removed and destroyed, and the bush should be sprayed with Nitrafen (before flowering) or 1% Bordeaux fluid.
- Mycoplasma growth. This disease has a viral nature and is transmitted by aphids and cicadas. Signs of infection are the appearance of numerous thin shoots up to 50 cm high, which are not able to bear fruit. The affected plant can not be treated, so it is dug up and destroyed so that the virus does not spread to neighboring bushes. Then they are engaged in the destruction of harmful insects using Topaz or Vectra preparations.
To prevent the appearance of these problems, it is enough to carry out simple preventive measures:
- choose healthy planting material;
- plant bushes in a sunny area with loose soil;
- regularly prune plants;
- comply with the recommended arrangement of bushes;
- observe the watering regime and the feeding schedule;
- regularly loosen the soil around the plants;
- carefully remove plant debris and debris from the area of the trunk circle;
- observe crop rotation.
Harvesting and storage
Ripe raspberries The sun lends themselves well to transportation and storage, but they must be removed from the bush immediately after ripening, as the ripened fruits quickly deteriorate, so the berries are removed from the bush in portions as their surface turns red.
The main recommendations for the collection and storage of crops are listed below:
- raspberries are harvested in dry weather in the morning or in the evening before dew;
- the berries are carefully separated from the bush, and then stack them with a thin layer in shallow dry containers of small size;
- for storage and transportation only elastic fruits are taken without damage, and the rest of the raspberries are used for processing;
- It is recommended to transport berries over long distances immediately after harvest, until their flesh has lost its density;
- fresh raspberries are stored in the refrigerator for several days.
Important! Raspberries The sun should be washed only immediately before use, so that the berries are not softened by water.
Raspberry Sun is able to please the gardener with a large number of sweet berries and attractive appearance of the bushes.Observing the tips for growing this crop listed in this article, you can get a generous harvest of universal fruits with excellent commodity characteristics.

I decided to talk about my "Sun". At the same time, someone else has this grade. Raspberry itself is winter-hardy, it gives enough offspring, a berry the size of a Balm. Slightly larger than average. Tasty, fragrant, sweet, especially in the presence of the sun. We are happy with our health, we treat it in early spring, Bordeaux liquid and Euphoria and Skor. Of course, I feed with fertilizers, mainly through a leaf. Her taste attracts, tasty, I have no sourness. It’s a pleasure to grow for yourself, but of course it won’t reach long distances. Collected in the morning (if left on the street at night), the flow begins in the morning. This is not critical if you collect, take home, well, and then either freeze or jam, for example. After freezing, the berry retains its shape and raspberry smell.
