Troubleshooting
Glacier Pink problems — and how to fix them
Glacier Pink (Dianthus glacialis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Death in warm, wet climates
This is a true high-alpine species that suffers badly in warm, humid lowland gardens. Cool summers and very sharp drainage are mandatory. In warmer regions, grow in a cool alpine house rather than outdoors.
Crown rot
Any moisture sitting on or around the crown is rapidly fatal. A generous top-dressing of small limestone grit keeps the crown dry and well-aerated. Never let the crown touch wet organic material.
Failure to establish
Young plants are sensitive at transplanting. Disturb roots as little as possible; plant into a pre-moistened gritty mix and do not water for several days after planting to allow the roots to seek moisture.
