I bought two anthemis punctata ssp Cupaniana plants and one of them looks very sad, leaves limp. The other in a different spot seems to be doing better altho I can tell it is not really happy either. My soil has alot of clay in it and I wonder if that is the problem. And if it is, what can/should I do about it? I am afraid the worst one won't make the summer the way it looks.. should I cut off all the blooms, dig it up now and put it in sandier soil?
