Yellow Pimpernel problems — and how to fix them
Yellow Pimpernel (Lysimachia nemorum) 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.
Drought stress and leaf scorch
Leaves yellow and wilt rapidly if the root zone dries out; the plant is not drought-tolerant — ensure consistent moisture, especially in summer.
Slug damage
Low, soft-leaved ground-cover is attractive to slugs in damp woodland gardens; check under foliage regularly and apply iron phosphate-based pellets if damage is severe.
