Landing Rules
Variety "Thornfree" refers to the late, so the planting of blackberries must be carried out in the spring. Autumn planting leads to weakening of seedlings, which may die in winter.
It is necessary to prepare the site and trenches in the fall. Blackberry bushes prefer sunny areas that are not too hot (high temperatures can cause the fruit to bake). But you should not choose a site where strong and cold winds penetrate, as this can lead to drying and freezing of shoots.
The ideal place for planting this variety is a flat area, which is protected from the north and northwest sides with a fence.
Loamy, non-acidified soils are the best option. If a site is selected where the soil is sandy, then it will need the application of good fertilizer, as well as digging in conjunction with black soil or clay. With a long absence of fertilizers on the territory in the autumn, it is worth spreading manure, ash, compost around the site, and then dig it up.
Humus must be poured into the planting hole, which is mixed with ash in advance. You can use complex fertilizers mixed with soil. In the spring, when the time for planting comes up, each of the cuttings should be shortened to twenty-five centimeters.Young blackberries should be planted in the prepared hole. In this case, the root neck should be deepened by three centimeters. Then you need to water the seedling.
The soil near the shrub needs to be covered with sawdust, dried grass or small dry branches. Thanks to mulching, the process of weathering of ground moisture can be prevented, as well as slowing down the growth of weeds. The distance between blackberry bushes should be about three meters, as these are quite massive plants.
Care
Caring for this blackberry variety includes standard activities:
- regular irrigation;
- weed destruction;
- top dressing;
- loosening the soil;
- bush formation.
The bush is considered quite responsive to organic fertilizer. A good reaction of the plant is observed when humus, ash and compost are introduced into the soil. In order for the ovaries to form better, it is worth fertilizing blackberries with urea, potassium complex and nitroammophos.
To ensure good taste and pleasant taste of the crop, it is recommended to mulch the soil under Thornfree. For this purpose, it is worth using agrofibers, raw materials from plants, cardboard scraps.
With intensive fruit ripening, the plant especially needs abundant irrigation. It is necessary to water blackberries well in hot and dry summers. But it is worth remembering that an excessive amount of moisture contributes to putrefactive processes in the root system. It will be enough to irrigate once every seven days, pouring about twenty liters of water under one individual. It is necessary to water the bush or not, you can understand by the state of the mulch. If it is wet, then the plant should not be watered.
Bush formation
According to experts, for high yields and normal plant life, it is necessary to form a bush and remove those branches that did not bear fruit in the current season. To form a fan-type shrub, branches with normal fruiting must be woven, stacking them on top of each other. During this process, you need to leave the newly formed shoots in free growth, but do not forget to place them in the same direction.
Pruning "Thornfree" involves shortening the length of the shoots with a pruner. This procedure leads to the activation of the growth of the lateral type of stems, but in the future they are also cut off.
Frost resistance of this blackberry variety is up to minus twenty degrees Celsius. This is the reason for sheltering the plant for the winter, no matter where in the country the shrub grows. It is not recommended to use a film for warming blackberries. It is better to give preference to the following materials:
- straw;
- spruce branches;
- agrofibre;
- slate;
- insulating mats.
"Thornfree" needs to raise the bush and fasten it to the trellis. When carrying out a one-sided garter, new and last year's branches are bred in different directions.
Diseases and pests
With proper planting and taking the necessary measures related to the care of blackberries, you can reduce the risk of disease and pest attack. In the neighborhood of "Thornfree" with a raspberry bush, it is worth setting a distance between plants of at least one hundred meters. Often, raspberries tolerate a latent form of green mosaic, which is detrimental to blackberries.
Blackberry variety "Torfri" is resistant to anthracnose, rust, stem cancer. But if signs of damage by these diseases are observed, biofungicides should be used immediately.
If a gall mite attacked a plant, then the berries do not have the opportunity to ripen, they remain red. This parasite is small in size and winters on bushes, later moving on to flowers, and then to berries. As a preventive measure in the autumn season, it is necessary to cut out old stems.
Spring treatment of plants by spraying with a strong infusion of garlic will be effective.
Reproduction features
To plant Thornfree blackberries, you can use one of three methods:
- green cuttings;
- root layers;
- top rooting.
Reproduction using green cuttings contributes to the preparation of a large amount of material for planting. This option is suitable for people who grow berries for the trade or want to create a living fence from Thornfree.
In the summer, the side branches must be cut into cuttings, the leaves should be removed from the sinuses. In this case, do not forget that you should leave the upper shoot kidney. All cuttings must be planted in nourished soil so that they take root. Usually about seventy percent of the planting material takes root.
The propagation method using root layers is no more complicated than the previous one, but there will be less material for planting. This method involves leaving several powerful layers near the mother. They will need to be looked after in the summer, and in the autumn it will be necessary to transplant. To avoid depletion of the mother bush, layering is deposited. In spring, there is a small survival rate of individuals that have not grown stronger.
The use of apical rooting gives a 100% guarantee that the plant will take root (subject to proper care).During the procedure, a tall shrub is bent to the ground and rooted. In this case, the shoot must be buried in the soil so that the crown remains outside.
Throughout the season, it is necessary to water the young plant abundantly, fertilize and loosen the soil. In the autumn, after harvesting, when the young individuals get stronger and grow, the blackberries should be separated and transplanted.
