Raspberry Unattainable - the name of this variety is very significant. You involuntarily begin to think about the parameters by which this raspberry is inaccessible to other varieties of this berry crop.
And reviews from gardeners about this variety are often contradictory, not coinciding with the main characteristics of the Inaccessible raspberry declared by the originators. In this article we will try to figure out how good the Inaccessible raspberry is for growing in garden plots, and whether it can be grown on an industrial scale.
Description of the variety
Inaccessible raspberry belongs to the remontant varieties, so its fruiting begins earlier than all other varieties of this berry crop; the first ripe berries on the bushes of this raspberry appear in the last days of July - the first days of August.
The fruiting period of this variety lasts until the onset of cold weather, so its name justifies itself - no other raspberry variety can “boast” of such a long fruiting period.
The bushes of this berry crop have to be harvested approximately once a week, resulting in up to 7 waves of fruiting over the entire season.
The height of the shoots of this raspberry rarely reaches 1.1-1.3 m. The maximum height of the bushes of this variety can be about 1.55 m; such a height can only be achieved if all the rules for caring for the plantation of this raspberry are followed. Bushes in width can reach a diameter of 0.7 m.
Therefore, you should not pay attention to the small size of seedlings of the Inaccessible raspberry variety and you need to remember that an adult shrub will also not be large in size, but flowers and berries will be located along the entire length of the shoots.
On the current year's shoots, the internodes are shortened, have no waxy coating, and small thorns are located along the entire length of the stem. At rest, the color of the shoots is brown with a yellowish tint.
Each raspberry bush produces up to 7 replacement stems, as well as about 10 root cuttings, so there will always be enough material for propagation of this variety. The shoots are quite well leafed. The foliage is quite large, on the outside it is bright emerald in color, slightly wrinkled, there are small jagged edges, there is no pubescence. On the reverse side, the color of the leaf plates is lighter.
Inflorescences and fruits begin to form and ripen from the top. The flowers are collected in inflorescences, each of which contains up to 4-7 berries. About 2-4 lateral branches are formed on the shoot, on which many fruit branches are formed. The length of the fruiting tip is about 0.9-1.1 m.
Diseases and pests
Raspberry Inaccessible is resistant to almost all diseases and pests. Defeat is possible only in case of non-compliance with agricultural technology.
Table: pest control methods and their prevention
| Pest | Description and nature of the lesion | Processing period | Control measures | Prevention |
| Raspberry stem fly | The insect is gray in size and up to 5 mm in size. Females lay eggs in the axils of the apical leaves. During development, the larva penetrates the stem. It manifests itself as withering, blackening and rotting of shoots. | At the beginning of bud break. | Treatment with Karbofos (75 g per 10 liters of water). |
|
| During the growing season. | Visual inspection, trimming damaged crowns. If there is a noticeable hole inside the cut shoot, you need to cut it even lower. | |||
| Raspberry beetle | The insect is black-gray and up to 6 mm in size. Females gnaw holes in the buds and lay eggs in them. The larvae gnaw out the contents of the buds and the tissue on the leaves between the veins. Manifests itself as massive leaf damage. You can also find larvae in the berries when picking. | Before flowering begins. | Treatment with Fitosporin (4 ml per 10 liters of water). | |
| Before the buds open. | Digging the ground under the bushes to a depth of 15–20 cm. | |||
| Raspberry stem gall midge | Mosquito up to 2.3 mm in size. The larvae are orange. The larva develops under the bark, feeding on the sap of the plant. Signs of damage: swellings up to 3 cm in volume appear on the stems, cracks in the bark, the shoot weakens and dries out. | Before flowering begins. | Treatment with Karbofos (75 g per 10 liters of water). | |
| During the growing season. | Cutting out and burning affected shoots. |

Larvae of raspberry beetles live in the berries until they ripen, and then go into the soil to pupate. Flies fly out when young shoots begin to grow. Orange-yellow caterpillars penetrate the stem, after which, after 3-4 weeks, swellings form in these places, the bark bursts and falls off.
Table: how to fight diseases, preventive measures
| Disease | Nature of the lesion | Processing period | Means for fighting | Prevention |
| Gray rot | The entire bush, including the fruits, is gradually covered with a gray fluffy coating. | Before the leaves bloom. | Treatment of the bush and soil between the rows with the fungicide Hom (30–40 g per 10 liters of water). | Draining the soil (spread a layer of charcoal evenly on the soil under the bush). |
| After flowering. | Treatment with Teldor fungicide (5 g per 4–5 l of water). | |||
| Anthracnose | It is manifested by the presence of gray spots with a purple border on the leaves (along the edges and along the veins) and on the shoots. The leaves curl and fall off. | Before flowering. | Treatment with Urea solution (20–30 g per 10 l of water). | Timely thinning of bushes, removal of weeds. |
| Before the flowers bloom. | Treatment with a 1% solution of Bordeaux mixture. | |||
| After flowering. | Treatment with Kuprikol fungicide (40 g per 10 l of water). Consumption - no more than 2 liters per bush. | |||
| Chlorosis | In mid-summer the leaves turn yellow. In the initial stage, yellowing is observed along the veins. Young shoots become thin and elongated. The berries dry out without ripening. | July August. | Affected bushes are completely uprooted and burned. | In early spring, the bush is sprayed with 1% Bordeaux mixture or copper oxychloride. |
| Root cancer | Dark brown growths appear on the shoots and growth decreases. | Autumn, spring. | Uprooting a bush. | Before planting, the roots of the seedling are disinfected in a solution of 1% copper sulfate. |

When infected with chlorosis, the shoots of the root shoots of infected bushes become noticeably thinner and significantly elongated compared to healthy bushes. Gray rot develops most actively in conditions of high temperature and excessive air humidity. Root cancer progresses especially quickly on alkaline soils. Anthracnose affects all above-ground parts of the plant, but especially leaves and shoots
Features of the fetus
The shape of ripe berries is conical, slightly elongated, the tip is slightly flattened. The color of the fruit is dark ruby, with a characteristic shine. On average, the weight of the fruit reaches 5-7 g, with good care they can reach 9-9.5 g. The length of the berries can reach 3.5-4 cm. The presentation of the berries is very attractive.
The tender juicy pulp contains practically no drupes, which are imperceptible in food. Therefore, Inaccessible raspberries are distinguished by their dessert taste and delicate fruity aroma.
But ripe berries are not held together too tightly, so they can fall apart when picked. Because of this, many summer residents say that the harvested crop does not tolerate transportation over different distances very well.
The fruits of this remontant raspberry are distinguished by their versatility of purpose - they are consumed fresh, added to desserts, prepared into preserves, jams, and frozen for the winter.
Remontant raspberry R-34, or Inaccessible
The history of the distribution of the Inaccessible variety across countries began back in the 80s. last century, and in 1988, a new cultivated variety of raspberries was presented at the Moscow Institute of Horticulture, the author of which was V.V. Kichina. The number P-34 was assigned to the variety in 1990, and since 1992 the variety has already been actively used for propagation.
The external features of the raspberry bush and its fruits often play a primary role when choosing seedlings of a particular crop, therefore, when assessing the qualities of the R-34 raspberry, it is worth studying all its characteristics, paying special attention to the existing advantages and disadvantages of the plant. Did you know? The productivity of raspberry bushes can be increased by planting them near a bee apiary.
As practice shows, active fruiting of the crop increases by 60–100%.
Did you know? The productivity of raspberry bushes can be increased by planting them near a bee apiary. As practice shows, active fruiting of the crop increases by 60–100%.
Appearance of the bush
The new plant is a powerful bush with spreading and fairly large shoots, the length of which reaches 1.4 m. From 5 to 7 replacement branches and the same number of root shoots are formed on one plant. All of them are elastic, strong, with shortened internodes.
The color of the bark is light brown, with a slight yellow tint. The wax coating is insignificant, the thorns are evenly distributed over the entire surface of the shoot. The middle leaves of the shrub are characterized by a bright green color, a flat and slightly curved leaf blade (the edge is predominantly crenate).
Characteristics of berries, fruiting dates, yield
The ripening, blunt-conical and slightly elongated berries of the Inaccessible variety are large and weigh on average 4–8 g. At the stage of full botanical maturity, the fruits have a characteristic ruby hue with a shiny glossy surface.
Under the medium-thick skin there is dense, sweet and sour pulp with a rich aroma. The core pit is small and almost unnoticeable during eating. The arrangement of the fruits in the hand is more friendly: they seem to support each other.
If you comply with the requirements for planting and further caring for the raspberry plantings in question, it is possible to collect 3–5 kg of fruit from one bush. The first time fruiting begins in mid-July, and the second time the berries are harvested from early August to September 10.
Advantages and disadvantages of the variety
Like any other remontant raspberry varieties, Inaccessible has advantages and disadvantages.
- The first group of characteristics includes:
- large-fruited bushes;
- early onset of fruiting;
- high resistance to diseases and pests;
- excellent transportability of the harvested crop;
- high resistance to many fungal infections and crop pests;
- excellent taste of berries;
- good productive qualities of raspberry bushes.
- As for the negative aspects, when growing the remontant variety R-34 you need to be prepared for:
- possible disruption of the taste properties of berries due to sudden changes in weather conditions in the region where the bush is grown;
- the need for regular removal of lateral growth, which quickly grows throughout the area;
- weak resistance to drought (in the southern regions the plant will definitely need shelter);
- possible fight against chlorosis, which develops on raspberries due to nutrient deficiency or limited amount of natural light on the site.
The high commercial quality of the fruit can also be considered as an advantage of the variety, since all the berries have almost the same size, shape and color, and among the disadvantages, some gardeners note the possibility of shedding part of the crop if it ripens excessively.
Main characteristics
This raspberry variety grows and bears fruit best in mild climates, without intense heat or heavy rainy seasons. During periods of extreme heat, the bushes slow down, and the berries bake and dry out. During the rains, the berries do not have time to accumulate the required amount of sugars, so they become too sour.
But the positive qualities of the variety include high resistance to frost, so this variety does not freeze out in regions with short, cool summers and harsh winters.
Productivity
With proper care of the bushes of this remontant raspberry, up to 6 kg of ripe produce is collected from each bush. But many gardeners say that if you do not apply too much fertilizing, then each bush produces at least 3 kg of raspberries per season.
Diseases and pests
Gardeners who grow these remontant raspberries on their plots do not have a clear opinion about the resistance of this variety to diseases and pests. But they all agree on one thing: if you grow raspberries as annuals, cut off all the shoots at the root every fall, remove all plant debris and fallen leaves, dig up the soil so that pests and pathogenic microorganisms have no place to hide for the winter.
Advantages
The main positive qualities of the remontant raspberry variety Inaccessible include:
- extended fruiting period - from the end of June until the first frost;
- the bushes are compact, so more plants of this variety can be grown on one square meter, thereby increasing the yield from a given plantation;
- good appearance of the fruit and excellent taste.
Flaws
- bushes of this variety do not tolerate heat well, so when growing this variety in the southern regions, this raspberry plantation should be shaded;
- if the soil lacks nutrition and light, the shoots may undergo chlorosis;
- the berries are not very well adhered to by drupes, so they do not tolerate transportation well;
- Bushes of this variety produce a large amount of shoots, which are not always needed in such quantities.
Advantages and disadvantages
Raspberry Inaccessible has both pros and cons in its care, and what will be decisive for you depends only on you and your conditions.
Among the undoubted advantages are:
- Early harvesting of berries, and combined with extended fruiting, makes it possible to harvest raspberries for almost two months.
- The compactness of the bushes makes it possible to use compacted planting and increase the yield per square meter.
- Commercial appearance of berries and their high taste.
Inaccessible raspberries also have disadvantages:
- Not very good heat tolerance, the need for shading in the southern regions.
- Seedlings can be susceptible to chlorosis if there is a lack of nutrition or poor lighting.
- Not too high adhesion of the berries and, as a result, low transportability.
- A large number of shoots can be seen as a disadvantage in some conditions, and as an advantage in others.
Landing
Inaccessible raspberry is very demanding on the quality of the soil in which it is grown, so you need to think about applying fertilizing when preparing a site for planting seedlings of this variety.
Usually, when planting raspberries in the spring, trenches with fertilizers begin to be prepared in the fall. Trenches are dug to a depth of approximately 2 shovels, and a mixture of organic matter and complex mineral fertilizers is added to a depth of 1 bayonet.
Bushes should be planted in a row at a distance of 0.65-1.2 m from each other, and the row spacing should be at least 1.6-2.0 m.
Requirements for soil and planting site
Raspberry “Unattainable” takes root well and grows in well-lit areas with loamy soil of neutral acidity or sandy loam and a groundwater level not higher than 1.2 m. The ideal place for planting is along a hedge or along buildings.
To plant raspberries, you need to choose southern, southwestern or western gentle slopes where moisture will not be retained. On steep slopes, the soil is washed out in the spring, and in the summer they dry out.
Neighborhood with rose hips, blackberries, and apple trees is undesirable - infection with verticillium is possible. It is also better not to plant tomatoes, potatoes, eggplants, and bulbous flowers nearby.
Acidic soils, if you plan to plant raspberries on them, need to be prepared two years before planting - add lime fluff, ground limestone, dolomite.
On a note! The best time for planting seedlings is the third ten days of September or the first ten days of October, when sap flow stops. Before spring, the plant will take root and grow faster in spring.
Planting options
You can plant raspberries using the bush or trench method, having prepared the site and soil in advance.
With the bush method, a hole is dug 50 cm wide and 30 cm deep, the soil is mixed with compost (50-10 kg), phosphate rock (1 glass), potassium sulfate (1 glass). Lime (100g) can be added to acidic soils.
With the trench method, a trench is dug 50-60 cm wide and 40 cm deep, superphosphate (120 g), potassium salt (30 g), ash (300 g) and 12-15 kg of manure are added per 1 m of length.
Feeding
You need to remember to apply fertilizers throughout the growing season, because the yield of bushes during the season directly depends on the amount of nutrients in the soil.
You should not apply too much fertilizer containing nitrogen during the season - this mineral promotes the active growth of vegetative mass to the detriment of flowering and fruiting. It is better to use wood ash for this berry crop, as well as mineral fertilizers that contain phosphorus and potassium.
It is also good to cover the soil around the raspberry bushes with compost or humus mulch after watering. The thickness of such a layer should be at least 6-8 cm.
Although it seems that the shoots of this variety are not very tall and therefore do not require gartering, it is better to garter raspberries on trellises so that the bushes receive better sunlight, make it easier to care for, as well as regular harvesting.
When to prune
Remontant varieties produce two harvests per season, but most often they are grown for autumn berry picking. In this case, the berries grow larger and of better quality. When harvesting twice, the plant needs more frequent feeding to prevent the fruits from being crushed.
After harvesting in the fall, pruning is carried out into two crops: at the root, without stumps, fruit-bearing branches are cut off, and annual shoots are left. After winter, the plant is inspected, diseased and dried branches are removed. You need to trim to the first healthy bud.
For one harvest, all shoots are cut off in the fall, without leaving stumps, 1-2 cm below the soil level.
Important! Pruning should be carried out in established cold weather - at high temperatures it will provoke bud growth.
Cut branches should be burned or removed from the site, thereby protecting the remaining plants from infections.
Preparing for winter
If raspberries are planted in open ground in the spring, and they have not yet bear fruit in the current season, before the onset of cold weather, the shoots are untied from the trellises, tied together, bent to the soil and covered with spruce branches, and on top - with any non-woven material.
When growing Inaccessible raspberries in the Urals, Siberia or other regions with similar climatic conditions, after autumn pruning of plants, the plantation is covered with roots to prevent the root system from freezing during the harsh winter.
If cold weather occurs in the region already at the beginning of autumn, then raspberry bushes with fruits that have not yet ripened are covered with a breathable covering material so that the last fruits have time to ripen on the bushes.
Features of cultivation and care
Raspberry Inaccessible is able to show its best side only with conscientious and attentive care. She is very partial to fertilizing - even when planting raspberries, it is better to fill the planting holes or trenches with 1.5-2 times more organic matter or mineral fertilizers. We should not forget about fertilizing during the entire growing season. But you shouldn’t be overzealous with nitrogen-containing fertilizers - it’s better to use wood ash, superphosphate, as well as complex fertilizers with a predominant content of potassium and phosphorus and a mandatory set of microelements.
Advice! Raspberry Inaccessible will appreciate a thick layer of organic mulch that will cover the root zone.
You can use a compacted fit. On average, 0.7 to 1.4 meters are left between bushes when planting, depending on the row spacing, which can be from 1.5 to 2 meters.
When pruning in spring, you should leave about 6-7 shoots per bush - this is the optimal amount for obtaining abundant harvests.
At first it seems that due to their compactness and relative short stature, the bushes do not require staking. But it’s better to arrange a single-row trellis in order to improve the illumination of the bushes, organize their maintenance and make harvesting easier.
Regular and abundant watering is necessary throughout the season, especially in areas with hot and dry climates.
Like all remontant raspberries, it is recommended to cut off all shoots at ground level before winter. This will make it possible to get one, but luxurious harvest at a time when traditional raspberries are no longer in sight. If you want to grow Inaccessible raspberries with two harvests per season (summer and autumn), then the overall result will still be less due to the shift in the timing of autumn fruiting into winter.
When planting seedlings in the spring, if they have not yet produced a real harvest, it is recommended to tie them together, bend them down and cover them for the winter.
Attention! When cultivating this raspberry variety in the northern regions, it is advisable to cover the planting site even after pruning the shoots in order to avoid possible freezing of the soil.
If frosts are already common in your area in September-October, it is better to cover the raspberry bushes with medium-density spunbond or any other breathable covering material to protect the last berries.
Reviews
Olga, 55 years old, Belgorod : we constantly grew raspberries on our plot, we tried many different varieties, but in the last few seasons we have only grown varieties bred by the breeder Kichina. All of them have good yields and do not require intensive care. Three seasons ago, Unbending raspberries were planted on the plot. This variety amazed us with its long fruiting. We collect the first berries in mid-July, and the last harvest is harvested at the end of October. In total, each bush produces at least 4.5-5 kg of ripe produce over the summer. But for this it is necessary to apply fertilizer to the bushes during the summer; for normal fruiting they need more nutrition than ordinary varieties.
Katya, 49 years old, Tver : Inaccessible raspberries have been growing on my plot for the fifth season. They planted it in the fall, the next season the yield of the variety was not too high, and the fruits themselves were a little sour - apparently, it was due to the fact that the summer was rainy. For the winter, the bushes were cut out and the plantings were covered with agro-canvas to prevent the roots from freezing. In the following seasons, the berries were larger, and the taste of the berries was better.
Harvest and storage
Fruit ripening occurs disproportionately. The first ripe berries appear in early July. The entire fruiting process lasts until October. The crop is considered by specialists to be high-yielding - the average fruit harvest from one bush is on average 4 kg, and with intensive care - 5 kg. The berries are picked by hand.
Inaccessible raspberries are suitable for consumption both raw and processed (in the form of jam, preserves, compotes, etc.).
After picking, the berries are placed in plastic or small wooden containers. In such containers they are suitable for transportation - this way the integrity of their structure is not compromised and the berries retain an attractive presentation.
The fruits are placed in small plastic or wooden containers. In such containers, they tolerate transportation well, maintaining their integrity and attractive appearance.
Raspberries of the “Unreachable” variety should be stored in a closed container at a temperature of 2-5 degrees. It should be stored in this form for no more than five days; after this period, the berries lose their visual appeal and taste properties. For long-term storage, raspberries should be frozen or processed.
