Blueberry Goldtraube 71 was bred by the German breeder G. Geermann. The variety was obtained by crossing American high-growing blueberries with low-growing narrow-leaved species V. Lamarkii. Blueberry Goldtraube 71 is not included in the State Register.
Description of the blueberry variety Goldtraube 71
Blueberry Goldtraube 71 is a deciduous fruit shrub of the Heather family. In adult form, it forms a sprawling bush, a well-developed root system. Subject to agricultural technology, it reaches a height of 2 m.

The description of the Goldtraube 71 blueberry indicates that the variety is suitable for growing in container culture. It has increased frost resistance, belongs to the 4th winter hardiness zone. Without shelter withstands temperatures down to -32°C.
Features of fruiting
Blueberry Goldtraube 71 is a self-pollinating variety. The bush can be planted singly. But with the possibility of cross-pollination with blueberries of other varieties, the yield increases.
The berries of the variety are light blue, rounded, 16 cm in diameter, collected in dense brushes. The weight of one berry is 1,9 g. The yield of the variety is average – 2,5-3 kg from one adult bush. In fruiting, the culture enters in early August. The taste of berries is sweet and sour.
Berries of the Goldtraube 71 variety are consumed fresh, used as a filling for pies and harvested in the form of jams and preserves.
Advantages and disadvantages
Blueberry bush Goldtraube 71 looks decorative throughout the warm season. The advantages of the variety are also in high adaptation to cold climates. Variety Goldtraube 71 is unpretentious in cultivation and is suitable for beginner gardeners.
The disadvantages of the Goldtraube 71 variety include its average yield and the presence of sourness in the taste of berries.
Features of reproduction
To preserve the characteristics of the garden blueberry variety Goldtraube 71, the propagation of the shrub is possible only by vegetative means. For reproduction, cuttings or layering methods are used.
For cuttings, the material is collected at the end of June from coppice shoots that take root better than shoots from the fruiting zone. Lignified cuttings are also suitable for propagation. Allotted shoots, which are pressed to the soil to obtain planting material, take root for a long time, within 2-3 years.
Planting and care
Blueberry variety Goldtraube 71 is demanding on soil acidity. The culture is grown only in an acidic substrate. The pH level of the soil should be 4,5-5,5. Unsuitable soil at the landing site is completely replaced with acidic soil, using a mixture of coniferous litter and riding red peat.
Recommended dates
Blueberry seedlings are kept in containers until transplanted. In the container, the seedling can be left for a long time before planting in the main place.
Young plants with a closed root system are transplanted throughout the warm period of the year. Spring planting is preferable, with it the plant has time to take root well during the summer and better tolerate the first winter.
Site selection and soil preparation
A place for planting blueberries of the Goldtraube 71 variety is chosen permanently, because an adult bush does not tolerate a transplant. Sites that have not previously grown other crops and the land has not been developed are best suited. The place for the shrub is chosen sunny, protected from strong winds. The depth of groundwater should not exceed half a meter.
In group planting, shrubs are planted in rows in the direction from north to south. The distance between the bushes in a row is 1,2 m, and between the rows – 1,5 m. Blueberry Goldtraube 71 does not coexist badly with other representatives of heather, for example, cranberries.
Landing algorithm
The root system of blueberries is fibrous, does not go far deep into the soil. A landing hole for one bush is dug 1 m in size on all sides and 0,5 m deep. For planting, the peat substrate is mixed with mineral fertilizer in the amount of 20-30 g per 1 sq. m. At the bottom, a drainage layer of about 5 cm is poured from rotted pine sawdust or bark.
In order for the blueberry bush to take root well in the future, when planting, it is especially important to break the earthen clod and release the roots, which, from a long stay in a tight container, grew inside the coma. To do this, the container with the seedling is released for 15 minutes. in water.
After soaking, the root system is freed from the soil and the roots are carefully straightened so that they are evenly located in different directions.
Planting a blueberry seedling:
- The plant is planted vertically, the roots are straightened, deepened by 5-7 cm from the total soil level. The soil is lightly pressed.
- Plantings are watered abundantly.
- The soil is mulched to a height of 5-8 cm with coniferous litter.
In order for the mulch not to erode from watering, a curb tape is installed along the diameter of the planting hole.
Cultivation and care
When growing blueberries, it is necessary to monitor the moisture and acidity of the soil, to keep the planting site clean from weeds. Otherwise, according to reviews of Goldtraub 71 blueberries, the variety does not cause difficulties in care. The annual growth of branches is 50 cm, green foliage and an increase in yield indicate that the shrub is grown correctly.
Watering Schedule
Maintaining soil moisture is necessary for the life of mycorrhiza. Drying out of the soil leads to the death of the plant.
For the entire period until the seedling takes root, the soil is kept moderately moist. For this, it is best to use drip irrigation. An adult bush is watered several times a week, using 10-15 liters of water for one watering. In dry weather, add spraying with water along the crown.
Abundant watering is especially important from mid-summer, during periods of fruiting and laying flower buds for the next season’s crop. Despite the exactingness of the culture for regular watering, moisture stagnation at the roots should not be allowed.
Top dressing schedule
For fertilizing blueberries, only mineral fertilizers are used, which begin to be applied from the second year of cultivation. The first feeding is carried out during the swelling of the kidneys, the second – after 1,5 months. Do not use manure, bird droppings, humus and ash to fertilize shrubs.
If the required pH level is violated, the shrub loses its yield, the leaves become pale green. To maintain the acidity of the soil in the spring, a handful of colloidal sulfur is added under the bush. Periodically, citric or oxalic acid is added to the water for irrigation in a ratio of 1 tsp. for 3 liters of water.
Trimming
For blueberry bushes of the Goldtraube 71 variety, only sanitary pruning is carried out. During the spring inspection, very thin and broken shoots are cut. After 5 years of cultivation, dry, non-fruiting branches, as well as small bushy growths, are removed from the bush.
Preparation for winter
Only young plants are prepared for winter, covering them with spruce branches. Mature bushes tolerate winter well, being under the snow. In areas with little snow, bushes can be covered with spunbond.
Pests and diseases
With proper agricultural practices, blueberries show good resistance to diseases and pest attacks. But with weak immunity and violations in care, the plant can be exposed to fungal infections.
Common pests of the shrub are May beetle larvae, leafworms and aphids. Tasty berries are eaten by birds.
Conclusion
Blueberry Goldtraube 71 is a fruit shrub, a cultivated form of wild blueberry. Subject to the peculiarities of planting and growing, the shrub brings a good harvest of vitamin berries at the end of summer, when many trees and shrubs have already finished their fruiting.
