Troubleshooting
Alpine Pink problems — and how to fix them
Alpine Pink (Dianthus alpinus) 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.
Crown and root rot
Occurs in waterlogged or poorly drained soils. Improve drainage with coarse grit and avoid overhead irrigation. A gravel collar around the crown helps keep moisture away from the stem base.
Fusarium wilt
A fungal pathogen causing yellowing and sudden collapse. Avoid planting in previously infected ground, ensure good drainage, and do not overwater. Remove and destroy affected plants.
Red spider mite
In hot, dry conditions, spider mites can colonise the foliage, causing fine speckling and bronzing. Increase air movement and treat with an appropriate miticide or insecticidal soap if infestations are heavy.
