Black currant: propagation by cuttings
Currant - one of the most useful and favoritemany garden crops. Care of it is not very difficult. Modern varieties are distinguished by excellent taste and abundant harvest of large juicy berries. The price of good planting material is not so high in comparison with fruit trees, but these costs can be avoided by growing seedlings on their own.
Care of the uterine plant
If there is elite or superelite currant on the site, propagation by cuttings will allow not only to increase the number of valuable shrubs, but also to sell surplus seedlings to those who wish.
When purchasing annual plants for breedingshould pay attention to the purity of the variety and the absence of disease, especially viral. When planting shoots are cut, leaving 3-5 kidneys above the ground. In the first year, the seedlings need special care: watering, loosening, feeding and combating the pest of the garden.
In autumn, leave 1-3 strong shoots, the restcut out. In the second year, reproduction of black currant can begin with cuttings. To shoots have matured well, at the end of summer they shorten irrigation and completely eliminate fertilizing with nitrogen.
Early autumn, when the rest period beginskidneys, black currant is best rooted. Reproduction by cuttings from the lower and middle lignified parts is more effective, the green, unripe crowns have a small supply of nutrients and develop worse.
As a rule, cut annual shoots with a diameter6-10 mm. They are divided into parts up to 20 cm long. The lower cut must be performed under the kidney, the upper one - above the kidney. Slices are made with a sharp pruner: the lower one - at an acute angle, the upper one - under a straight line. For better survival, the cuttings are placed in the root stimulants, but this is not necessary.
Landing should be done a month before the onsetcold in the prepared soil. Cuttings are immersed at an acute angle into the ground, leaving one kidney on top. Then the soil should be compacted and watered. Lunge during autumn planting is less than 30%.
If the necessarydilution of currant, propagation by cuttings can be carried out in the spring. In this case, the material is harvested in winter and at the very beginning of spring. It can be stored in moist sand at zero temperature, in a bag in the refrigerator, or in the snow in the area.
Such a landing has its own peculiarities:
- cuttings are planted as early as possible, otherwise the survival rate drops sharply;
- The ground before planting is covered with a black film,Cuttings stuck into the soil through it. This will save heat and moisture reserves, which contributes to the rapid development of the root system and relieves gardeners from loosening and weeding.
Reproduction of black currant with green cuttings
From the beginning of June to the end of July, you can start green propagation. This method is more laborious, but has its advantages:
- You can get a lot of new seedlings from this year's shoots.
- The uterine shrub quickly gives branches, on which fruit buds are laid for harvest next year.
- Planting material is guaranteed to be clean from pests such as gall midges, glass beetles, and kidney mites.
First, the first varieties are cuttings, then later currants. Reproduction by cuttings is optimal in mid-July.
Better take root annual shoots of the first order of branching 10-15 cm long. The top two leaves should be left, and the rest removed.
Soil for planting should be loose,nutrient, aerated and drained. Cuttings stuck into the ground obliquely and deeply enough: only the crown with leaves remains above the surface. They should be constantly moistened and weed. Rooting occurs in 3 weeks, then watering is reduced.
To obtain a large number of plants, you cancut cuttings with two kidneys and one internode. Their lower parts are immersed in root stimulators, then they are planted vertically to a depth of 1.5 cm. The soil is crimped, a film shelter is installed above the cuttings. In the hotbed until the roots are kept high humidity. Then the film is removed. Several times during the summer, foliar top dressing is performed.
In the middle of autumn, young plants are ready for planting in a permanent place.
