Moorcroft's Sage problems — and how to fix them
Moorcroft's Sage (Salvia moorcroftiana) 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 rot
The most common killer of this species in UK gardens is cold, waterlogged soil in winter; plant in raised beds or add ample grit to the planting hole, and consider a dry winter mulch over the crown.
Powdery mildew
Overcrowding and poor air circulation encourage powdery mildew on the large woolly leaves; space plants generously and avoid overhead watering late in the day.
