Pest identification
What's eating my elecampane?
Slugs and snails
Signs: Ragged, irregular holes in large basal leaves; slime trails on soil and lower foliage; seedlings and young plants most vulnerable.
Control: Set beer traps or copper-tape barriers; apply wildlife-safe iron-phosphate pellets (e.g. Sluggo) around the base after rain.
Aphids
Signs: Distorted, sticky new leaves; clusters of small insects on shoot tips; honeydew promotes sooty mould.
Control: Encourage ladybirds and lacewings; spray with insecticidal soap or diluted neem oil, targeting the undersides of leaves.
Deer
Signs: Browsed or torn upper stems and large leaves, often overnight; whole shoots may be stripped in late spring.
Control: Use physical exclusion (deer netting or fencing) around young plants; plant among other strongly scented herbs as a mild deterrent.

Elecampane pests — FAQ
What is eating my elecampane?
Elecampane is a robust outdoor herb but faces slugs and snails that shred young leaves at ground level, and aphids on soft new growth. Powdery mildew from poor airflow can weaken stems. Deer occasionally browse the large foliage. Good spacing, slug traps, and aphid monitoring keep most problems manageable.
