Balkan Rock Pink problems — and how to fix them
Balkan Rock Pink (Dianthus simulans) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Crown rot and cushion collapse
The compact habit traps moisture at the crown in wet winters or humid summers; top-dress around the cushion with a deep layer of coarse grit and provide overhead protection in particularly wet UK winters.
Vine weevil larvae
Grubs can sever roots beneath the cushion undetected until the plant suddenly wilts and lifts free of the soil; apply nematode biological control (Steinernema kraussei) in early autumn as a preventive measure in alpine troughs.
