General description of thornless blackberry varieties and photos
The appearance of the studless blackberry is attractive. The openwork plant forms a large bush covered with bright green foliage with a jagged edge. Flowers appear around mid-June. The exact date depends on the variety: early, medium or late. The inflorescences are often white, but a pink or lilac hue may be present. Fruiting lasts from a month or longer, which also depends on the characteristics of the variety. The berries are green at first. When ripe, the fruits first turn red, then turn dark purple or black.
The root system of the thornless blackberry is buried up to 1.5 m, which allows the plant to survive the drought without reducing yield. The culture is considered two years old. The first year the bush grows fruiting shoots. In the second year, they bring berries, and in the fall, the branches that bear fruit are cut off. The replacement shoots are prepared for the next fruiting. In one place, a thornless bush can bear fruit for up to 10 years. Then the plant is transplanted to another place.
One-year old is considered to be shipless. repairing blackberry... The plant bears fruit on the branches of the current year. In the fall, shoots are cut at the root. In the spring, new branches grow and immediately begin to bear fruit.
According to the structure of the bush, the bushless culture is divided into two types:
- Kumanika - an upright plant with strong, weakly bending branches. Shoot length reaches more than 3 m. Kumanika sprouts a lot of young growth.
- Rosyanika - a creeping plant. Flexible stems are extended over 6 m in length. The dewdrop does not let young growth from the root. An exception may be damage to the root system. A young shoot can go from the cut root.
Semi-creeping varieties are less common. In such a culture, strong shoots with a height of about 50 cm grow evenly, then they begin to creep.

- To get one harvest, in the fall, all branches of the remontant blackberry are cut to the root. In the spring, new fruiting shoots grow.
- To obtain two harvests in the fall, only old, fruiting shoots are cut out. Young shoots of blackberries are bent to the ground and covered.

Rules for choosing the right variety of thornless blackberries
To grow a studless blackberry on your site, you need to choose the right variety. First of all, frost resistance and ripening times are taken into account. It depends on these factors whether the blackberry is suitable for the climatic conditions of the region.
After choosing a suitable group, you can already look at the yield, berry size, bush structure and other characteristics of the variety.

Blackberries without thorns: planting and care
The agricultural technique of the thornless blackberry is used the same as for the thorny relative. In the second year after planting the seedling, it is recommended to pluck all the inflorescences from the fruit branches in order to enable the root system to grow.
Recommended timing
In cold regions, spring planting of thornless blackberries is preferable, falling in April - early May. In the south, the seedling will have time to take root before winter with an autumn planting. Usually, disembarkation is done in September.
Choosing the right place
For brambleless blackberries, choose a bright area well-lit by the sun. It is important to protect the plant from winds, strong gusts of which are often observed in the Moscow region. It is optimal to plant bushes along the fence, retreating at least 1 m.
Soil preparation
A bed for planting a studless blackberry is dug to a depth of 50 cm, humus or compost is added. In addition, before planting seedlings, a bucket of humus mixed with fertile soil, potassium fertilizer and superphosphate is introduced into each hole - 25 g.
Selection and preparation of seedlings
When buying, choose seedlings with a developed root system, two twigs, where live buds are present. Before planting, the plant is dipped in warm water by its roots. The procedure accelerates the growth of root shoots.
Algorithm and scheme of landing
The optimum planting depth of a blackberry seedling is 50 cm. A hole with a fertile mixture of soil and humus is watered. After planting the seedling, another watering is performed, after which the soil is mulched. The aerial part is shortened, leaving twigs 30 cm high.
The planting pattern depends on the variety of the thornless blackberry. Between compact bushes they maintain a distance of up to 1.5 m. For creeping highly growing varieties, a gap of at least 1.8 m is maintained between the plants. The row spacing is from 2 to 3 m.
Blackberry care in spring, summer and autumn
To get a good harvest, the thornless blackberry needs care during the entire growing season.
Principles of growing thornless blackberries
All studless blackberries, regardless of the growth of the bush, need a garter to support. It is optimal to install trellis made of posts and wire. To increase the yield, top dressing is applied, a bush is formed, the soil is loosened and mulched. In the fall, superphosphate and ash are necessarily introduced into the soil. In the spring, the bushes are fed with compost and ammonium nitrate.
Necessary activities
The following actions are distinguished from the mandatory measures for caring for the thornless blackberry:
- In the fall, blackberries are provided with shelter, which is removed in the spring immediately after the snow melts.
- The soil around the bushes floats from weeds, loosened after each watering, mulch to retain moisture.
- Watering is carried out once a week, and then while the berries are being poured. Long roots themselves get moisture from the depths of the earth. Spring and autumn watering is required to charge the bush.
- Top dressing cannot be done with fresh organic matter. Rotted manure works well. In the spring, nitrogen-containing fertilizers are applied to stimulate the growth of the bush. Suitable for 20 g of ammonium nitrate per 1 m2 beds. During fruiting, phosphorus is introduced, closer to autumn - potassium.
Pests rarely visit blackberries, but when they appear, plantations are sprayed with chemicals.
Pruning thornless blackberries in spring
Only sanitary pruning is done in spring. Remove old, fruiting shoots if they were not cut out in the fall. Additionally, all frozen branches without buds are cut off. When pruning, they do not leave hemp so that pests do not start. Repaired thornless varieties are not cut off in spring, since all branches are cut off at the root since autumn.
More information about pruning thornless blackberries is shown in the video:
Preparing for winter
After the autumn pruning, the thornless blackberry is prepared for wintering in cold regions. The lashes are removed from the trellises, tied with twine, pinned to the ground with wire. Erect bushes have fragile shoots. To prevent them from breaking, loads are tied to the tops since autumn. Under the weight, the branches of the blackberries tend to the ground, and they can be easily covered.
Spruce branches are ideal for warming bushes of thornless blackberries. The thorns prevent rodents from getting started. You can use a non-woven fabric paired with a film.
The video tells about the correct hiding place for blackberries:
Reproduction of thornless blackberries
You can independently propagate a thornless blackberry in the following ways:
- Seeds. A difficult method that does not preserve the varietal characteristics of the culture. Seeds do not germinate well.
- Layers. In August, the lash is bent to the ground, covered with soil, leaving only the top. The following spring, the plants are cut from the mother bush and planted.
- Cuttings. Twigs 15–20 cm long from lignified shoots germinate best in moist soil. You can cut green cuttings from the tops, but you will have to cover the planting with a greenhouse.
- Air layering. The vaccination site is wrapped with a piece of film covered with earth. The primer is constantly moistened from a syringe with a needle. After a month, a stalk will appear with a root that can be detached.
Spineless blackberries are not propagated by offspring, since these varieties do not allow young growth. The option of dividing the bush or root cuttings is possible, but the process requires accuracy and is difficult for novice gardeners.

Summer residents treat diseases and destroy pests on the blackberry bushy with the help of folk remedies. The list of actions is presented in the table. The main enemy of the culture is white bloom or mite. From store-bought drugs they use "Skor" or "Saprol".
