Potato variety Rosalind is a product of the work of German breeders. Recommended for cultivation in several regions: Central, East Siberian, Central Black Earth, North Caucasus.
Description
In early Rosalind potatoes, bushes form semi-erect, of medium height. The bright green, open type leaves grow to medium size.
Tubers ripen with a mass of 60-110 g, and up to 16 potatoes can form in one bush. Oval-rounded fruits stand out with a red smooth skin and yellowish flesh (as in the photo). The starch content is 12,2-17%. It takes 53-61 days for the crop to mature. The Rosalind variety is distinguished by excellent keeping quality (95-97% of tubers are preserved).
If you pre-sprout the planting material, then the rate of maturation of the tubers increases. Therefore, it is not surprising that in the southern regions, experienced gardeners harvest twice a season.

Landing
An important guarantee of a bountiful harvest is fertile soil. Loose, well-ventilated and moist soils are more suitable for Rosalind potatoes.
Preparatory stage – disinfection of planting material and land:
- Tubers are processed by special means. Colfugo Super is a liquid seed dressing agent. Neutralizes many diseases, has a long period of action, promotes the friendly emergence of seedlings, is not phytotoxic. The agent is well retained on the surface of the tubers – it is resistant to washing off with water (when watering or during rains). The consumption rate is 2 ml per kilogram of potatoes. It is to combat late blight that Fitosporin-M is used. Consumption – 10 ml per kilogram of material.
- For cultivating the land, “Force” or “Aktar” is used. These products disinfect the soil and help fight the wireworm after planting potatoes. The recommended dose is 0,5 kg per hundred square meters. To simplify the processing process, it is better to scatter the granules during the planting of the tubers (the agent should be near the root system of the plants).
Planting work is carried out after the threat of frost. Soil temperature at a depth of 8-10 cm should be at least + 5-8˚С. Rows of Rosalind potatoes are best placed in a north-south direction. Holes 8-10 cm deep are dug with a distance of 65-70 cm between rows and a step of 25-30 cm in a row.
Care
Rosalind refers to varieties that respond quickly to high-quality agricultural technology. And this should not be neglected, because with proper care, the yield increases by 15-20%. The following activities should be carried out on a regular basis:
- weeding;
- shallow loosening, due to which the air conductivity of the soil increases;
- hilling;
- fertilization.
Bushes should not be flooded. In order for water to flow well to the roots of Rosalind potatoes, it is desirable to make grooves parallel to the rows.
Hilling and top dressing
These are the most necessary procedures, without which it is difficult to expect a good harvest. It is recommended to do this work in cloudy weather, when the ground is wet.
Ruled out
When hilling a Rosalind potato bush, moist soil is raked up to the roots. This procedure will allow you to get the maximum yield, as it promotes the formation of new tubers. An additional effect is the loosening of the soil around the plants, in which the earth is saturated with air and dries out more slowly. Rosalind potatoes are spudded for the first time after germination. During the season, bushes are usually spudded twice with an interval of three to three and a half weeks.
How to feed potatoes
Gardeners who prefer organic fertilizers can use semi-mature manure or compost (a mixture of peat and manure). If you immediately pour wood ash into the hole or into the trench, you can get a greater effect. An excellent crop of Rosalind potatoes also ripens with the use of inorganic fertilizers.
Nutritional compositions are introduced in several stages. For each time it is important to choose the appropriate mixture.
- The first time top dressing is added to the soil after germination. Apply nitrogen-containing compounds ammonium sulfate, ammonium nitrate. Since Rosalind potatoes should quickly build up a green mass. You can use a solution of 15 g of urea and 500 ml of mullein per 10 liters of water.
- As soon as buds appear and tubers begin to set, the plants are fertilized again. At this time, Rosalind potatoes need potassium and phosphorus. Therefore, a mixture of 15 g of potassium sulfate, half a glass of wood ash, 15 g of superphosphate, diluted in 10 liters of water, is suitable.
- Three weeks before digging Rosalind potatoes, the soil is fertilized with a solution of superphosphate (30 g) and slurry (25 ml) diluted in a bucket of water (10 l). About half a liter of fertilizer is poured under each potato bush.
Do not neglect top dressing, especially organic. Since these additives improve the structure of the earth, they make it looser.
Diseases and pests
The main danger for the Rosalind variety is late blight, which damages the tubers, the aerial part. The first signs of damage are darkened spots on the leaves. The disease leads to the death of the tops, and the infected fruits rot during storage. A reliable means of control are chemicals. Tops 25-30 cm high are sprayed with special solutions (Bordeaux mixture, copper sulfate). Before flowering, Exciol, Epin are used if damp cool weather has set in. When warm and dry, you can apply Krezatsin, Silkom. As soon as the bushes fade and tubers begin to actively form, it is recommended to spray Rosalind potatoes with Alufit.
preventive measures
It is known that the disease is easier to prevent than to cure. This expression also applies to the plant world. The most popular preventive measures:
- plant only healthy material, do not place potato beds in damp lowlands;
- thinning of the rows – a strong thickening of the planting is not allowed;
- timely hilling of Rosalind potato bushes;
- if rainy weather is planned, then it is advisable to dig up potato tubers earlier.
After harvesting, it is important to carefully remove the remains of tops, tubers. It is best to burn the remaining post-harvest litter.
Harvesting
Sometimes, due to inexperience or following the advice of inexperienced neighbors, novice summer residents delay digging potatoes. Such slowness when harvesting early varieties can lead to crop loss. The optimal time for digging Rosalind tubers is the first half of August. But more precisely, the period is determined individually and depends on climatic conditions. Indeed, in case of rainy weather, the harvest is delayed.
The popularity of the Rosalind variety among summer residents is fully justified. Potatoes ripen early, have an excellent taste, are moderately starchy and do not fall apart when cooked. Therefore, they are suitable for preparing various dishes.
