Troubleshooting
Pink mountain heather problems — and how to fix them
Pink mountain heather (Phyllodoce empetriformis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Summer heat stress and browning
Even within its North American native range, P. empetriformis is restricted to cool subalpine zones. In lowland gardens with warm summers it declines. Best results come from cool-climate gardens, north-facing alpine beds, or high-altitude rockeries.
Spider mites in dry conditions
Prolonged dry and warm conditions encourage spider mite infestations, causing stippled, bronzed foliage. Increase humidity, improve irrigation, and treat with an appropriate miticide or neem-based spray if infestation is severe.
Sparse flowering
Insufficient winter cold or excessive shade can reduce flower production. Ensure at least some direct sunlight and allow plants to experience natural cold winters. In very mild regions, flowering is often poor regardless of other conditions.
