Himalayan Cassiope problems — and how to fix them
Himalayan Cassiope (Cassiope fastigiata) 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.
Stem rot in waterlogged or overly wet winter conditions
Prolonged winter wetness in heavier soils causes collar and stem rot; the plant is adapted to free-draining rocky Himalayan soils. Grow in raised beds with gritty drainage and provide cloche or cold-frame protection in wet winters.
Reluctance to flower in lowland cultivation
Like other high-altitude Cassiope species, C. fastigiata often fails to flower freely in lowland gardens because the combination of high light, low temperatures, and distinct seasonal rhythms of its native habitat are hard to reproduce; an alpine house with good ventilation gives best results.
