Troubleshooting
Yellow Prairie Wild Indigo problems — and how to fix them
Yellow Prairie Wild Indigo (Baptisia sphaerocarpa) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Slow establishment
Plants may take 3 years to reach flowering size and are extremely resentful of root disturbance; plant young container-grown specimens into their permanent position and do not attempt to divide or move mature plants.
Powdery mildew in late summer
Foliage can develop a white powdery coating in late summer, especially in humid years or where air circulation is poor; cutting plants back by one-third after flowering improves airflow and often prevents mildew, with no effect on the following year's display.
