Troubleshooting
Sand Pink problems — and how to fix them
Sand Pink (Dianthus arenarius) 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.
Root rot from overwatering
The biggest cultivation problem. Sandy, free-draining soil is essential. In garden beds with heavier soil, raise the planting area or add at least 50% coarse sand to improve drainage.
Short-lived in heavy or moist soils
Even in otherwise suitable gardens, plants die out in 2–3 years in moisture-retentive soils. Treat as a short-lived perennial and propagate regularly from cuttings.
Aphids on new growth
Young shoots can attract aphids in spring. Treat with insecticidal soap or neem oil. Ants farming aphids on sandy ground plants can be an early indicator of an infestation.
