Troubleshooting
Variegated Japanese Spurge problems — and how to fix them
Variegated Japanese Spurge (Pachysandra terminalis 'Variegata') 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.
Green reversion
All-green shoots occasionally arise and are significantly more vigorous than variegated growth, quickly outcompeting it if not removed. Cut reverted stems to ground level as soon as noticed. High-nitrogen fertilisers increase reversion frequency.
Volutella blight
Fungal stem and leaf blight causes brown, papery patches with pink spore masses in damp weather. Remove affected stems, improve air circulation, and apply preventive copper or chlorothalonil fungicide in early spring. 'Variegata' may be slightly more susceptible than green forms due to its weaker growth habit.
Marginal leaf scorch
White leaf margins brown at the tips in conditions of drought, high heat, direct sun, or salt spray. Ensure consistent moisture, position in shade, and avoid salt-based de-icing products near plantings in winter.
