What's eating my geranium himalayense 'gravetye'?

Geranium himalayense 'Gravetye' is a hardy garden cranesbill. Vine weevil grubs are the most destructive threat, chewing roots unseen. Aphids cluster on new growth, and slugs and snails rasp young leaves overnight. Deer and rabbits generally avoid true hardy geraniums due to their aromatic foliage.

Plants wilt and collapse as C-shaped grubs eat roots underground; adults notch leaf edges at night Apply nematodes (Steinernema kraussei) to moist soil in late summer or early autumn; use vine weevil killer drench for containers

Soft colonies on shoot tips and flower buds cause distorted growth and sticky honeydew Blast off with a strong water jet; encourage ladybirds and lacewings; apply insecticidal soap if colonies persist

Ragged holes in leaves and flowers, especially on young spring growth; slime trails visible Use iron phosphate pellets or copper tape around containers; hand-pick at dusk; encourage ground beetles and hedgehogs
