It is the end of August, flowers in apple tree are not blooming where the flowers in Apricot, Nectarine, plump trees bloomed already. Last year, I didn't get apple in my apple trees. I thought it was because of fungus problem as I didn't take care in winter. This year, I spayed Yates fungicide just before winter and again middle of this month (August).

You may need another apple tree, to cross-pollinate, to ensure fruit develops.
