I have an acer which has been attacked by blackfly, what can I do - this is the second one which has been attacked



Not a problem, just get yourself a decent pesticide spray that deals with aphids, preferably a systemic one which will stop reinfestation for up to 2 weeks. Or if you don't like chemicals, use water with washing up liquid in it - it'll kill the ones present on the plant, but won't stop them coming back again.
