Breeding history
Black currant Lama is a domestic variety obtained in 1974 at the Lisavenko Research Institute of Horticulture in Siberia. The authors are N.S. Antropova, I.P. Kalinina, Z.S. Zotov and N.I. Nazaryuk. When crossing, two varieties were taken as a basis - Black Lisavenko and Leah fertile.

Characteristics
Llama is a black currant variety bred for the difficult climatic conditions of Siberia. The culture is unpretentious, so both an experienced and a novice gardener can cope with its cultivation.
Drought tolerance, winter hardiness
The currant variety Lama has high winter hardiness, withstands frosts down to -30 ° C without shelter. It does not tolerate drought well: in the heat, additional abundant watering is required, otherwise the yield will noticeably decrease, and the berries will become sour.
Pollination, flowering period and ripening times
Black currant Lama belongs to self-fertile varieties - it does not require pollinators, mono-planting is possible (only one variety). In terms of ripening, the culture is medium early. Flowering occurs in mid-June, and the peak of fruiting occurs in the second decade of July.
Productivity and fruiting, keeping quality of berries
The yield of Lama currants averages 2.7 kg per bush. With industrial cultivation, about 9 tons per hectare are harvested, the maximum recorded figure is 19.5 tons. Ripening is amicable, which makes harvesting easier. Keeping quality and transportability of the fruit is average, since the skin is not very strong.
Disease and pest resistance
The currant of the Lama variety is distinguished by good resistance to typical diseases and pests: powdery mildew, bud and spider mites, and gall aphids.
Therefore, as a preventive measure, it is enough to carry out one spring treatment of currant bushes of the Lama variety with a fungicide. You can use Bordeaux liquid, Skor, Tattu, Fundazol or other means. Home infusions are used to kill insects:
- wood ash and laundry soap;
- tobacco dust;
- onion peels;
- garlic cloves;
- baking soda.
In case of severe infection, insecticides are effective - "Fufanon", "Decis", "Green soap", "Biotlin" and others. The processing of currant bushes of the Lama variety is carried out in the evening, in dry and calm weather.
Advantages and disadvantages
Lama black currant has a number of advantages. This is an unpretentious culture, which was bred just for the climatic conditions of Siberia.
Pros:
- pleasant taste of berries;
- good immunity to diseases and pests;
- friendly fruiting;
- the crop can be harvested manually and mechanically.
Minuses:
- berries are not too large;
- keeping quality and transportability are average.
Features of planting and care
When buying seedlings, you need to carefully examine them so that the roots and shoots are completely healthy. Planting is best planned for the first decade of October, but this can be done in early April. The place for currant bushes should be sunny, protected from winds and waterlogging (lowlands should be avoided). The optimal soil type is fertile, light loam.
If the soil is clayey, 1 kg of sand or sawdust is embedded in it on the same area.
Algorithm for planting currant seedlings Lama standard:
- Dig several holes 50–60 cm deep at a distance of 1.2–1.5 m.
- Lay a layer of small stones.
- Pre-soak the roots of seedlings in "Kornevin", "Epin", "Zircon" or another growth stimulator.
- Plant at a 45 degree angle.
- Sprinkle with earth, deepening the root collar by 5-7 cm.
- Tamp a little, water abundantly.
- Mulch for the winter with peat, sawdust, dry foliage, cover with spruce branches.
In normal weather conditions, 2 buckets per bush should be given twice a month, and in hot weather - weekly. In the late evening, you can periodically irrigate the crown. Moreover, in the first year after planting, the seedlings are watered 2 times a week.
Starting from the second season, top dressing is applied:
- in April, give urea (20 g per bush);
- in early June - mullein, humus or cut grass infusion;
- during the formation of berries - complex mineral fertilizer (30–40 g per bush). At the same time, you can pour a solution of boric acid (3 g per bucket of water).
Mature bushes also need to be tied up.Loosening and weeding is carried out as needed. In the spring, they must do sanitary pruning, and in the fall - formative (12-15 strong shoots are left). They water it well for the winter, dig in the bushes, and after the first frost they cover it with burlap.
Reproduction methods
Lama currants can be diluted by cuttings and layering. In the first case, in June, cut green cuttings up to 20 cm long, make an oblique lower cut and soak in a growth stimulator. Then they are planted under a film in a mixture of peat and sand (1: 1), carefully mulched in the fall, and transplanted to a new place in the spring.
Layers are obtained at the end of spring - the lower shoots are instilled to a depth of 10-15 cm, fed, watered regularly, and mulched for the winter. In the spring, all cuttings with roots are cut, transplanted to a permanent place and nitrogen fertilized.
Conclusion
Currant Lama is an unpretentious variety that can be grown both in Siberia and in other regions. The bushes are strong, vigorous, the yield is stable. When leaving, remember to regularly water and fertilize. For the winter, you need to cover only in regions with an unfavorable climate.
