Hi, we are newer to the island and planted a Summerred apple tree and a Louisa weeping crab apple, when we landscaped 2 seasons ago. It blossomed at that time, and we got 7 apples from it that year. Last year with the winter we had we feared the apples and roses might be worse for wear. Not so, we had a glorious blossoms in late April and 30 apples off this small tree. This year the crab is fully blossomed and has its leaves but the apple has gone straight to leaf. It looks healthy. What could be the problem?
