Is the weather in the north suitable for growing potatoes?

Potatoes in the north are sown in spring and harvested in autumn. Generally, seeds can be sown many times in the south and only once in the north, mainly because of the cold weather in the north.

When potato tuber is used for asexual propagation, seed potato can germinate and grow at 5 ~ 8 soil temperature, and the optimum temperature is 15 ~ 20. The suitable temperature for the growth and flowering of plant stems and leaves is 16 ~ 22. The optimum temperature for tuber formation at night is 10 ~ 13 (soil temperature is 16 ~ 18), and when it is higher than 20, tuber formation is slow. When the temperature drops to -2 during excavation and seedling stage, it will freeze.
