Scarletta Leucothoe problems — and how to fix them
Scarletta Leucothoe (Leucothoe fontanesiana 'Scarletta') 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.
Loss of scarlet colour
Deep shade prevents the intense spring flush of red. Position where new growth receives some morning light. Nutrient-deficient acidic soils can also reduce colour intensity; ensure adequate ericaceous fertiliser.
Fungal leaf spot
Dark lesions spreading across leaves are caused by several fungal pathogens. Keep foliage dry when watering, remove affected leaves, and improve air circulation. Severe cases may require copper fungicide treatment.
Winter desiccation scorch
Exposed, windy sites cause evergreen leaves to lose moisture while frozen roots cannot replace it. Mulch deeply before winter; site in a sheltered, shaded position to reduce cold drying winds.
