Woolly Jerusalem Sage problems — and how to fix them
Woolly Jerusalem Sage (Phlomis lanata) 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.
Winter wet / root rot
Wet, cold soils in autumn and winter are the primary killer; plant in raised beds or on slopes with added grit, and avoid overhead irrigation in autumn.
Legginess and poor flowering
Lack of adequate sun or over-feeding with nitrogen causes weak, sprawling growth and fewer flowers; cut back lightly after flowering to maintain a compact shape.
