does anyone know how to get rid of whitefly on a clematas on an arbour. I walk through this to get into my back yard and hate the little white things that fly out when the clematas is nudged as I pass. Do I need to cut the clematas back? it is the kind of plant that dies back every winter and comes fresh each spring. this is the first year it is a problem. seeds are like friends, when attended to they are plentiful and flourish
