Diagnosing Hosta Damage: Slugs vs. Disease

Diagnosing Hosta Damage: Slugs vs. Disease

A gardener asked what was eating hostas. Two types of damage were evident: clean-edged holes (slug/snail feeding) and brown, irregular margins with yellowing (fungal disease).

Integrated Approach

• Control slugs/snails with baits, traps, or barriers.
• Improve air circulation and avoid overhead watering to reduce disease.
• Fertilize with Milorganite or Holly-tone to boost plant vigor and new leaf production.
