What is the suitable temperature for potatoes?

Potatoes like cold, fear frost and avoid heat. When the soil temperature is 4-5℃, it begins to take root and germinates at 5-7℃, and 15- 18℃ is the best. It is most suitable for sandy soil with deep and soft soil layer, good ventilation and good drainage.

Stem and leaf growth period

The growth of stems and leaves is very sensitive to temperature. When the temperature reached 2 1℃, the stems and leaves grew vigorously. When the temperature is 24℃, the fruit bearing of potato is delayed. When the temperature is lower than 4℃, the stems and leaves are frozen and the plants die at -2-3℃.

Tuber formation and expansion period

The optimum temperature is 15- 18℃, when the temperature is 29℃, the tuber stops growing, and when the soil temperature is-1-2℃, the tuber freezes to death. High temperature, drought, tuber dysplasia, and even plant death. Under the condition of sufficient fertilizer and water and short sunshine, it is beneficial to the development and expansion of tubers.

Harvest storage period

Choose sunny weather to harvest. Storage requires low temperature, dryness, ventilation and light avoidance. It is easy to germinate above 5℃ and rot below 0℃.
