How to plant potatoes: sprouts up or down?

Planting a large area with potatoes, many simply throw them into the holes, without bothering to turn the tubers, the shoots themselves know in which direction to grow. But it turns out there are 2 planting methods: sprouts up and down.

Before planting potatoes, they need to be germinated. The sprouts should not exceed 1.5 cm, otherwise they will break. Over time, old tubers begin to sprout on their own during storage, especially in warm and humid rooms. When the planting material is ready, it remains only to choose the planting method: upside down or down. The supporters of the first method give their arguments.

• It is easier for the eyes to germinate in the direction of their direction, especially in heavy clay soils. In such soil, sprouts turned into the depths of the earth may not make their way.
• Germinating, the upper eyes eventually become the aerial part of the plant; for their development, they receive nutrition from the mother tuber. A little later, stolons (roots) develop from the upper shoots. They branch down and out to form new tubers.
• Eyes directed downward grow slowly, and in cold soil they can die altogether without breaking through from under the soil. This will not happen if they are directed upwards.
• If potatoes are planted in deep holes (more than 10 cm), the eyes should be at the top of the tuber, the lower sprouts cannot rise from such a depth.
• Eyes extending downward lose a lot of energy to germinate from under the soil, and strength might be needed to strengthen a young plant... For this reason, the planting material should not weigh less than 80 g, otherwise the sprout will not have enough nutrition for long-term growth.
• Colorado beetles actively attack the young shoots that came out of the ground late, because it is softer than tough, already grown plants.
• In southern regions, late shoots suffer from intense summer heat, some of them may die.

There are many supporters of this method, and they have their own "iron" arguments.

• Tubers sprouted upward develop too quickly and may be delayed by late frosts. The lower eyes give later shoots when the weather is already warmer.
• The shoots from the upwardly planted eyes do not know any obstacles during growth, grows evenly, heap, in a bunch. In cramped conditions, the shoots interfere with each other and do not receive enough air and light, which means that they cannot actively develop. The lower shoots make their way, bypassing the mother tuber, and emerge from the ground from different sides in a wide bush, without forming crowding, which gives them the opportunity to strengthen in free growth and bring a good harvest.
• The eyes receive a lot of moisture.
• To break through from under the ground, the shoots need to lengthen more than the upper shoots, which means that they can form more stolons. This fact directly affects future yield.

Each method has a right to exist, as it has strengths and weaknesses. You can use both methods in a small area only when manually planting potatoes.

Planting seed potatoes outdoors involves many important factors, not just the ability to direct the seedlings up or down. The future yield depends on the quality of planting, and everyone chooses the method of planting for himself.
