Crested Phlomis problems — and how to fix them
Crested Phlomis (Phlomis crinita) 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.
Crown rot
The most common cause of death, typically occurring in winter in poorly drained or heavy soil. Plant on a slope or raised bed and avoid mulching around the crown.
Powdery mildew
Can appear on the woolly foliage during humid summers; improve air circulation by not overcrowding plants and avoid overhead watering.
