What is the best time to fertilize apple trees?

We have seen many people asking this common but tricky question. You cannot just mix fertilizer in soil under extreme heat or rain. Spring is the best time for fertilizing apple trees. For more clarity, early spring is the best idea. These are because trees need more energy to push out a new look, blooming flowers, and bearing baby fruits. This time you should feed the trees while bud-break or a growing season is going on. We suggest you not choose the fall season for fertilizing as trees drop out leaves on the next season, winter. There is no chance of notable growth after using fertilizer in the fall.
