Shrub Potentilla in the wild is found in Altai, the Far East, the Urals and Siberia. A dark, tart decoction of branches is a popular drink among the inhabitants of these regions, which is why the second name of the shrub is Kuril tea. Potentilla Goldstar is a varietal representative of the culture, used for decorative design of personal plots.
Description of Potentilla Goldstar
Potentilla Goldstar (pictured) is a popular crop used by professional landscapers and amateur gardeners. The frost resistance of the variety allows it to be grown in the climate of the European part of Our Country. Perennial cinquefoil Goldstar gives an average growth of about 15 cm per year, keeps its shape well throughout the growing season, does not require constant crown formation. The unusual structure of the leaves and long flowering give decorative Potentilla from spring to late autumn. After the end of flowering, the color of the crown acquires a dark yellow color, the leaves fall off with the onset of the first frost. Variety Goldstar is wind-resistant, but does not tolerate moisture deficiency.

How does the yellow cinquefoil Goldstar reproduce?
Potentilla Goldstar is a varietal representative of the species; when grown by seeds, it retains the characteristics of the parent bush. Breeding options:
- cuttings. The material is cut from last year’s shoots, less often from stiff stems, in the latter case the plant takes root worse. In June, cuttings up to 25 cm in size are cut from the middle part of strong shoots. Leaves and flowers are removed, the lower part of the material is lowered into Kornevin for 10 hours. They place it in the ground, create greenhouse conditions, cover it with cut plastic bottles from above, and constantly water it. The Goldstar variety is planted in a permanent place after 1 year;
- layers. The lower branch is fixed with staples to the ground, covered with earth. The procedure is carried out in the spring before the leaves appear. A year later, the plant is divided and seated;
- seeds. Planting material is collected at the end of September, in the spring, before sowing, the seeds are stratified and treated with a solution of manganese. Sown in a mini-greenhouse on the surface of the soil.
When the growth reaches 10 cm, it is dived into separate containers. At the first stage of the growing season, the Goldstar variety grows rapidly; a year later, the shrub is planted on the site.
You can propagate the Potentilla shrub variety Goldstar by dividing a four-year-old bush. This method is rarely used, an adult plant after transplantation does not always take root.
Planting and caring for Potentilla Goldstar
Under favorable conditions, the plant blooms in the second year, develops and grows up to 4 years. Further vegetation is aimed at crown formation and flowering.
Recommended dates
Potentilla Goldstar is grown from the Arctic Circle to the Southern regions, so the planting time in each area is different. In warm climates, planting can be done in the spring, after the snow has melted, when the soil has thawed enough to dig a hole. Approximately mid-April. Potentilla is planted in autumn in September, when at least a month remains before the onset of frost. This time is enough for the plant to take root on the site. In areas with cold winters, autumn planting is not considered. Planting work is carried out only in spring, when the soil has warmed up to +7 0C.
Site selection and preparation of soil
Potentilla Goldstar for abundant flowering requires a sufficient amount of sunlight. The site is determined without a shadow in an open space. The duration of the biological cycle of cinquefoil is 30 years, this factor is taken into account when choosing a place, an adult plant does not respond well to transplantation.
Preference is given to fertile loams, the composition of the soil should be light, aerated with satisfactory drainage. The soil is neutral or slightly alkaline. On an acidic composition, Potentilla Goldstar grows poorly, loses the decorative effect of the bush, and blooms weakly. The landing site is prepared in the fall. The site is dug up, if necessary, the acidic composition is neutralized with dolomite flour, organics and urea are added. The photo shows the optimal size of the Potentilla shrub Goldstar seedling for planting, care recommendations are described below.
How to plant
Before planting, the seedling of Potentilla Goldstar is checked for damage, if necessary, dry or weak fragments of the root system and stems are removed. The root is dipped for 10 hours in a growth-stimulating solution, then in a concentrated clay substance. A fertile mixture is prepared from sand, soddy soil, compost in equal proportions, ash and mineral fertilizers are added.
Planting cinquefoil shrub Goldstar:
- Dig a planting hole so that the diameter is 2 times the root system. Depth is determined by the length of the root to the neck plus 35 cm.
- A layer of drainage (15 cm) is placed at the bottom.
- The nutrient mixture is poured on top.
- The seedling is placed in the center of the hole, covered with soil left over from digging the hole.
After planting, the plant is watered. About 10 liters of water are needed per bush, the root circle is mulched with sawdust mixed with peat or wood shredded bark. When creating a hedge, the interval between plants should be 35 cm.
Growing rules
Kuril tea Goldstar can be attributed to an undemanding representative of the species. Like any ornamental shrub, cinquefoil needs some care.
Watering
Variety Goldstar is characterized by medium drought resistance. In its natural environment, the shrub is often found in wetlands along the banks of water bodies. Overmoistening of the soil perceives more calmly than a dry root ball. Young Potentilla seedlings up to 2 years old are watered every evening under the root, sprinkling is carried out three times a week. Watering for adult plants is oriented to seasonal precipitation, it is necessary that the near-stem circle is always wet.
Additional fertilizing
During spring planting, microelements necessary for growth are introduced. At the end of August, you can feed the cinquefoil with an organic solution. From the next spring, before the appearance of buds, urea is introduced, at the beginning of flowering – potash fertilizers. In early August, Potentilla Goldstar is fertilized with superphosphate. After flowering, organic matter is added and the basal circle is sprinkled with ash.
Loosening, mulching
Loosening is a prerequisite for agricultural technology, the event is relevant for young seedlings. Do not allow compaction of the top layer of soil. For the formation of the root system, an unhindered supply of oxygen is necessary. For an adult Goldstar variety, three loosenings per month are enough. Weeding is carried out as they grow. Weed grass is a breeding ground for pests and infections.
Potentilla mulching is carried out immediately after planting, using peat, tree bark or sawdust. In autumn, the layer is doubled, straw or needles are used. In the spring, the material is updated. Mulch for Potentilla Goldstar has a multifunctional purpose: it retains moisture well, allows oxygen to pass through, and prevents overheating of the root system in summer.
Pruning, bush formation
The plant calmly responds to the formation of the crown, the structure of the bush allows you to create any shape, depending on the design decision. After pruning throughout the season, it retains its decorative effect and does not require re-molding. The photo shows an example of using Potentilla shrub Goldstar as a hedge.
Pruning required for Potentilla Goldstar:
- Sanitary. Carry out in the spring before the buds swell, remove shrunken, weak, twisted, twisted stems. They cut off shoots and top shoots, raise the crown, improve ventilation and light transmission.
- Rejuvenating. Cut out the old central stems, which affect the decorativeness of the shrub and give the cinquefoil an untidy look. The stems are cut near the root. Rejuvenating pruning is carried out 1 time in 3 years in case of drying out of the tops of old stems, if they do not give growth, and, accordingly, flowering.
- forming. Form the crown of the Goldstar variety in the fall, cut off all the shoots by 1/3 of the length.
After 6 years of vegetation, the Goldstar cinquefoil shrub is cut off completely, the stems are left 15 cm above the root, the plant will recover in spring, the young stems forming the crown will bloom profusely.
Pests and diseases
Resistance to infection and pests in Goldstar cinquefoil is satisfactory. The plant is sick infrequently, at low air humidity and high temperature conditions, a spider mite parasitizes on the shoots of Potentilla, for pest control, the drug “Floromite”, “Sunmite” is used. It is possible to spread the caterpillars of the scoop butterfly, destroy the pest with the preparations “Decis”, “Zolon”. From fungal infections, powdery mildew may appear; at the first sign, Goldstar cinquefoil is treated with Bordeaux liquid.
Conclusion
Potentilla Goldstar is a perennial deciduous shrub with long abundant flowering. The culture is frost-resistant, tolerates temperatures down to -40 0C, resists the wind well. Light-loving ornamental shrub demanding watering. Potentilla Goldstar is used in landscape design as a tapeworm, hedge. Include in the composition with undersized flowering plants.
