The hanging baskets at the front of my house are covered in Black Fly and the plants (Nasturtiums, Begonias, Fuschias and Geraniums) are looking very sad and sorry for themselves.

I tried squirting them with soapy water, but the problem got worse, so I have resorted to Doff Greenfly and Black Fly Killer. I am hoping that will resolve the matter.

Are the plants likely to recover? They were doing really well a week or so ago, but now, the Nasturtiums in particular, look yellow and unwell.

Thanks
