I have a Stella fanned cherry tree against a wall. First year and have lots of cherries appearing. However this morning noticed lots of black tiny spots at the end of the branches and curled up leaves.I have just sprayed it with a malathion solution.should I take the pest ridden leaves off or not and when should i spray again or what should I do.
