When pruning, the pruning method should be changed according to the growth years of fruit trees. If the young branches are just planted and grow vigorously, they can be pruned appropriately. Cut the long branches short, preserve nutrition and promote the growth of the main branches.
If the fruit trees are planted for a long time, you should cut off the branches, dead branches and diseased branches that grow too densely, and leave more side branches to adjust the column shape. In addition, some main branches should be cut and trimmed, which can control the loose nutrition and make them bloom more.

Growth habit
Apple can adapt to most climates, and 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℃, and 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. Thereby reducing the probability of suffering from frost. However, for some varieties and regions, the frost effect is more obvious there, so an effective anti-freezing system is necessary.
