Troubleshooting
China pink problems — and how to fix them
China pink (Dianthus chinensis) 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.
Fusarium wilt
Wilting despite moist soil with yellowing at crown indicates Fusarium. Remove affected plants immediately; improve drainage and rotate planting sites annually.
Aphids
Clusters of green or black aphids on young shoots distort growth. Knock off with a strong water jet or treat with insecticidal soap; ladybird predators provide natural control.
Failing to re-bloom
Spent flowers left on the plant trigger seed set and halt further blooming. Deadhead regularly by removing faded flowers to the next bud or leaf node.
