Growth habit
Apples can adapt to most climates. It is the best choice for apple growth between 35-50 degrees north and south latitude. Apples need 1000- 1600 units of heat and 120- 180 days of frost-free weather.
Warm during the day and cold at night, and as much light radiation as possible is the premise to ensure good quality. Apples can resist the frost of minus 40℃.
If the temperature is between -2.2℃ and -3.3℃ during flowering and fruiting, it will affect the yield. Compared with other deciduous crops, apples bloom later. It is most suitable for neutral and well-drained soil with pH value of 6.5.
