I have two Honey Crisp trees that had disease last year with the apples with scabs and worms as I sprayed too late. This year the trees only have a dozen or so blossoms, unlike last year when they were full of blossoms. I’ve sprayed once before the bloom and it’s my understanding that I shouldn’t spray again until the blossoms fall. But I don’t understand why there are so few blossoms this year. Do I need to feed the trees?
