I live in the Midwest just south of Chicago tree is in sun majority of the day soil is black dirt with a little clay it’s about 5 to 6 years old the base of trunk is about 5 inch across and about 12 feet high And after 2 to 3 years I would get fruit but would get to about a Olive size and drop off around June And the leaves would get holes in them and I had ants and I think a problem with those Japanese beetles last year no fruit at al I have been applying Bonide fruit tree spray for the past few years with no luck I pruned it this year when dormant and the tree blossomed white and now the leaves are on it and looks very healthy any suggestions Should I spray it now with the Bonide, need some advice thanks
