Hi, last year I planted 4 semi-dwarf apple trees; Honeycrisp, Sweet 16 and Zestar. All produced fruit last year. This year, only the Sweet 16 had any blossoms at all, and probably only 4-5 total on a single branch. Any thoughts on whether there's a problem? Or is this typical for newly planted trees (each were about 6-7' tall when brought home, so I'll guess maybe 3 years old then?). Here's more detail:
I live by Minneapolis. The trees get about 8 hours total direct sun throughout the day Spring thru Summer; however, I noticed last fall that with the changing angle of the sun, that was reduced in the final weeks of the season. Last year, the first year the trees were in the ground, I thinned the fruit. I also pruned early in the season last year, but not at all in the Fall, and not at all this year. I have not fertilized the trees.
This year, the trees seem to be producing far more leaves than last year. Some of the leaves seem larger than what I recall from last year.
So back to my question. Any ideas why no flowering/fruit this year?
