Apple tree - no blossoms
First time poster here, please be gentle.
I have three young apple trees. Number one I planted three years ago (liberty, dwarf). Two and three I planted last year (Honey crisp, pink lady, dwarfs).
The Honey Crisp and Pink Lady bore no fruit last year (as expected) and this spring are blossoming beautifully.
However, the Liberty bore fruit nicely last season, but sadly this year has no blossoms - not a one! However, there is lots of nice green leafing and appears quite healthy.
I bought these trees from a local nursery at about five feet (Holly Orchards is the brand) in 10 gallon pots. They have been watered and fertilized with manure. Light spraying of lime sulfur this spring. No pruning of any of these small trees yet.
I'm clueless - why no blossoms (and no fruit this year)?
Thanks for any advice!
