Troubleshooting
Transylvanian Pink problems — and how to fix them
Transylvanian Pink (Dianthus callizonus) 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 / collar rot
The primary killer of alpine Dianthus: persistently wet soil at the crown, especially in winter, leads to rapid collapse. Ensure a gravel collar around the plant base and excellent soil drainage; raised alpine beds dramatically reduce risk.
Aphids on flower stems
Colonies of aphids can distort emerging flower buds and check growth; treat with a strong water jet or an insecticidal soap spray early in the infestation before populations build.
