Extreme cold during the winter can kill fruit buds on some trees. Winter weather rarely threatens hardy apple, pear, and plum varieties. F can kill their fruit buds. As fruit buds grow and open they become more susceptible to injury from frost. Remember, the health of the fruit tree, the fruit tree's environment, the tree's fruiting habits, and the cultural practices used influence the fruit tree's ability to produce fruit.
Adequate pollination is also essential to fruit yields.
If these conditions are not favorable, we may have reduced yields or perhaps the tree will not bear fruit at all.
