Blueberry growth optimal temperature of 13-30 ℃ can tolerate a maximum of 40-50 ℃ high temperature, higher than this temperature range will lead to the root system of poor absorption of water and stunted. Different types of blueberry distribution areas have different climatic conditions. Dwarf blueberry growing season in the distribution area is short, cold winters and cool summers, the average annual temperature of 5-12 ℃, December to January the following year, the average temperature below 0 ℃, the extreme minimum temperature of up to -40 ℃.

North highbush blueberry distribution area climate conditions between the above two distribution areas, the average annual temperature of 10-120 ℃, the growing period of 150-250 days. The average monthly temperature in winter can be up to 0 ℃ or less, the absolute minimum temperature is often -20 ℃, but not below -30 ℃.
