Broad-Leaved Primrose problems — and how to fix them
Broad-Leaved Primrose (Primula latifolia) 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.
Primula leaf spot
Fungal spots (caused by Ramularia and related species) appear as brown lesions on leaves, particularly in humid, warm conditions; remove affected leaves and avoid overhead watering.
Slugs and snails
Young rosette leaves are very vulnerable to slug damage in damp, shaded positions; apply grit mulch around plants and use wildlife-safe slug pellets or nematodes (Phasmarhabditis hermaphrodita).
