I think I have white fly on my lupins. One plant is badly infected and I got to spray it before it bloomed but now it has bloomed and I can see the whitefly on the other lupin I was wondering should I cut off all the blooms and spray again or should I just cut to the ground as I don’t think I am able to get all the flies as there is too much foliage. Or should I just leave the flies alone?
