I planted 2 young dwarf apple trees last year. I do not know the exact ages of the trees, but one is about 6 feet tall and the other about 5.5 feet. The 6-footer has tons of blossoms. This is a gala. The other one, which I think is a jona gold (lost the tag), has leaves, but no blossoms. Is this typical? I read that some young dwarf trees will not flower for 2-3 years, but again, I am not certain of the age of these trees.
