Creeping Gaultheria problems — and how to fix them
Creeping Gaultheria (Gaultheria nummularioides) 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 kill in cold or exposed positions
This high-altitude species tolerates only brief, light frosts; prolonged cold below -5°C, or cold drying winds, will kill exposed growth. In the UK, protect with horticultural fleece and ensure a well-drained root zone to prevent frost-rot.
Soil alkalinity and chlorosis
Even slight lime contamination triggers interveinal chlorosis and gradual decline. Test soil pH annually and acidify with sulphur chips or ericaceous compost top-dressing; always use lime-free water.
Prevent creeping gaultheria problems before they start
Most creeping gaultheria issues are care-mismatch, not bad luck. Dial in the basics:
