Aphids and Acers
After commenting on Acers yesterday and saying mine were all looking good - on further inspection of what I thought was a wee touch of frost damage on 2 (both Palamtum) it seems that they are infested with aphids. On looking into buying some ladybirds it seems that they are not available til mid may.
I have sprayed with provado (I do know that it isn't idead but it was the only thing I had too hand) and covered them with fleece just in case it was a touch of frost damage.
Will it be safe mid may to still buy the ladybirds and release onto the plants after treating with spray or should I wait a while longer?
