Yellow Mountain Heath problems — and how to fix them
Yellow Mountain Heath (Phyllodoce glanduliflora) 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.
Heat-induced collapse in lowland gardens
This snow-bed alpine cannot tolerate sustained summer temperatures above 20°C; plants rapidly wilt, desiccate, and die if exposed to warm lowland conditions without shade and consistent cool moisture — it is best suited to Scottish Highland gardens, high-altitude peat beds, or alpine troughs.
Root rot in wet or compacted soils
Winter waterlogging rapidly kills roots; ensure gritty, free-draining acidic soil and raise the planting area in heavy soils — alpine troughs with drainage holes filled with a grit-rich ericaceous mix are ideal for container culture.

Most yellow mountain heath issues are care-mismatch, not bad luck. Dial in the basics:
