Troubleshooting
Neglected Pink problems — and how to fix them
Neglected Pink (Dianthus pavonius) 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.
Aphids
Colonies of greenfly cluster on young shoots and flower buds, distorting growth. Treat early with a strong water jet or insecticidal soap; avoid nitrogen-heavy feeding that promotes the soft growth aphids favour.
Crown rot (Fusarium / fungal)
Waterlogged soil or organic mulch touching the crown leads to rapid stem-base rot, which is usually fatal. Ensure perfect drainage, use a grit collar, and position the plant so the collar sits slightly proud of soil level.
Rust and powdery mildew
Both fungal diseases appear in humid, poorly ventilated conditions. Remove affected foliage promptly, improve air circulation, and apply an appropriate fungicide if infection is severe.
