I have an Euphorbia amy. Purpurea planted April 2014 and am unsure what to do. I'm told it should be cut to ground level now but it looks so good now. However I did not cut it last year and it did not look good earlier on. Also should I divide it next spring?
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?
