Angela Keays asked 11 years ago

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.

Cherry blackfly is a kind of greenfly, causing the leaves to curl.  A bad attack may need to be treated as it can weaken the tree, but usually the tree is hardly affected.

Any greenfly control will do. It can be treated on a trained tree, a free-standing tree is usually too big.
