Cultivating a variety

Landing is carried out in two ways: traditional (tubers) and seeds. For the second option, you must first germinate the seeds, then grow seedlings at home, and then transplant it into the open ground. Seeds are planted in April, and seedlings are transplanted into open ground no earlier than in the middle of May.

When planted with tubers, the planting time is the same as for ordinary potatoes.

When choosing the timing of planting take into account the climatic and weather features of the region. Be sure to wait until the threat of night frost has passed.

Soil preparation

Try to choose light soil for planting purple potatoes. Oxygen should easily penetrate into it and do not stagnate excessive moisture. An excellent option would be neutral sandy loam, as well as floodplain and sod-podzolic soils. Before the onset of the first frost conduct a rough primary digging the selected area. During frosts, the larvae of the pests that were in the inverted land will die.

Land for colored potatoes in the fall should be dug up with the introduction of potash fertilizer and superphosphate

With the onset of heat, when the minimum soil temperature reaches 5 ° C, begin planting. Pre-re-digging of the soil is done, the wells are prepared with the addition of wood ash. The distance between the rows should be at least half a meter, and between the holes it is kept at 30 centimeters.. Depth of landing reaches 10 centimeters.

Planting and care

If the soil in the selected area is dry, then watering should be carried out at least three times: immediately after germination, during flowering and immediately after it. In the absence of rain plants should be irrigated at least once a week. If there is a lot of moisture, fungal diseases will develop, and with its lack of planting they can dry out.

During planting, care should be taken to ensure that plants have good access to air and light. To do this, you should not save space and plant bushes very close to each other, and observe the recommended distances.

After the emergence of shoots of purple potatoes it must be weed regularly and remove weeds. When a crust appears on the soil, it should be loosened. Regularly treated beds with drugs against the Colorado potato beetle, late blight and other common pests and diseases.
