Cultivated black currants
The shrub reaches a maximum height of 2 m, with a pleasant taste, sour-sweet berries of black or dark blue.
The sugar content is 15%, the acidity of 4.6% of vitamin C, contains up to 400 mg %.
Black currant, and red, propagated vegetatively: by dividing the Bush, layering and cuttings.
In the case of reproduction by layering young shoots are laid on the ground in the groove 5-7 cm deep, pressed tightly to the ground by wooden or iron hooks. This work should be done in autumn or early spring.
Before laying the shoots in the grooves of the soil must be podrujit to a depth of bayonet spade, the tops of the shoots to bring to the surface and cut 1/4 lengths to invoke the more powerful germination of the kidneys, located closer to the base of the shoot.
Spring shoots appear to 20-60 cm, dampen and Spud land. Well, if the earth mixed with humus, the soil escapes to repeat the filling height of less than 10cm.
If the soil is not wet, before hilling needs to be watered. The second would be good to make a liquid fertilizer of mineral and organic fertilizers.
In the future, carry out timely weeding from weeds and to the extent necessary, apply pesticides. With good care of layering for autumn shoots grow up to 20 cm with well developed rhizome.
Fall branches cut pruning shears from the mother Bush and dig with a shovel. From one Royal Bush you can get up to 15 seedlings. The most developed are transplanted to a permanent place.
Underdeveloped seedlings for rearing leave the school. Leave the weak seedlings in the second year about Royal Bush should not, since their digging can damage the root system of uterine bushes.
Method of propagation of woody cuttings can be used for all types of currants, but the best results are obtained from the black. With this method, you should follow some conditions first and foremost the correct period of harvesting cuttings and planting time.
The best period of harvesting, regardless of the timing of planting — early autumn (beginning and middle of September). For autumn planting the cuttings is better to cook at the end of August.
For cuttings you need to take healthy ripened annual grasses (basal) shoots. Prepared shoots cut sharp garden knife or shears to a length of 20-22 inches.
Under the kidney make the bottom cut slanting, top — right, 2-4 mm above the kidneys. Part of the shoots, having a thickness of less than 4-6 mm, not suitable.
The best planting time is early September. At this time the soil is warm and the air is cool. This promotes good formation of callus (the beginnings of roots) and set the active relationship between soil and cuttings. In early spring they start off in growth.
To plant currant cuttings in the spring should be as early as possible, while the temperature does not rise above 10°. To choose their landing sites with moist, fertile soil dressed with organic fertilizers.
Drop them off better in the series. Aisle to leave a width of 20-30 cm, distance between rows of cuttings — 10— 15 cm Plant they need to be inclined at a 45° angle to the furrow, leaving the land no more than 2 buds.
During the summer it is necessary to retain moisture, loosen the soil, protect the plant from pests and weeds. As necessary, carry out the glaze.
After rooting the cuttings should be fed with nitrogen fertilizers and organic. Last is it better to apply in furrow irrigation. Excellent results are obtained by mulching the soil.
For the year under favorable conditions from cuttings, you can obtain good seedlings that you plant in a permanent place of residence. Weak seedlings are planted in shkolku for another year for rearing.
With little care, especially the lack of moisture, all the seedlings have to leave in the second year and dig them only at the age of two.
Green cuttings: the last time this technique is becoming increasingly important.In the arid climate green cuttings yields positive results, if for rooting cuttings created by the mode of constant optimum humidity.
This can be achieved by growing them in greenhouses or under plastic shelters in two layers and maintaining a high humidity, which will help to avoid the risk of overheating.
Cuttings green cuttings harvested when they have finished growth but are not woody (mid-summer).
Cut them in the morning or on cloudy days and stored until planting in cool and wet place. Their length is 10 cm. Transplanted them to a mixture composed of two parts earth and one part sand.
Rooting for the best recommended used growth promoters (IAA and others). During rooting and plant growth is necessary to maintain the temperature of 22-25°.
The mixture should be well moistened, but at the same time, and well aerated, to avoid rotting stems. In the autumn rooted cuttings are planted in shkolku on rearing.
The division of the Bush. This method is used when transplanting bushes for a more rapid propagation without additional rooting. The Bush divide with a saw or secateurs PA several parts so that the individual parts had well-developed roots.
Transplanted them out should be cut so that each shoot has remained 2-4 buds with them for a season with good care, will grow strong enough shoots.
