Troubleshooting
Dusky Coral Pea problems — and how to fix them
Dusky Coral Pea (Kennedia rubicunda) 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 in heavy or waterlogged soil
The most common cause of failure. Kennedia rubicunda is intolerant of wet feet. Plant in raised beds or improved drainage if soils are heavy. Never irrigate established plants in winter in cool climates.
Powdery mildew
Can develop on foliage in humid, still conditions or when plants are under moisture stress. Improve air circulation, avoid overhead watering, and apply a sulfur-based fungicide if severe. Healthy plants in good conditions rarely suffer.
Excessive vigour / invasiveness
Can become aggressive in warm, moist conditions. Prune hard after flowering in spring to control spread and maintain shape. In some regions outside Australia, check local invasive species status before planting.
