What's eating my hosta 'june'?

Slugs & snails

Signs: Irregular holes throughout leaves, often large enough to ruin the ornamental display; worst in spring on new growth.

Control: Iron-phosphate pellets around crowns; beer traps; copper tape on pots; hand-pick at night; encourage hedgehogs (UK).

Deer

Signs: Entire stems and leaves browsed to stubs, sometimes overnight; devastating in rural and suburban gardens.

Control: Deer repellent spray (reapply after rain); physical fencing; plant in a walled garden or courtyard.

Vine weevil (Otiorhynchus sulcatus)

Signs: Notched leaf edges from adults; larvae eat roots causing sudden wilting and plant collapse, mainly in containers.

Control: Apply nematodes (Steinernema kraussei) to compost in late summer/autumn; check pot roots when repotting.

Foliar nematodes (Aphelenchoides spp.)

Signs: Brown streaks running between veins giving a striped or scorched look; most common in humid summers.

Control: Remove and destroy affected leaves promptly; avoid overhead watering; do not compost infected material.
