What's eating my geranium sanguineum 'album'?

Geranium sanguineum 'Album' is a compact, drought-tolerant cranesbill seldom badly troubled by pests. Vine weevil is the most significant threat, with adults notching the deeply divided leaves and larvae attacking roots. Slugs graze young growth, and rabbits may nibble plants in spring if borders lack protection.

Notched leaf edges; larvae eat roots causing wilting and plant death in late summer or autumn Use biological nematode drenches (Steinernema kraussei) in late summer; physical removal of adults at night

Holes and torn edges on tender spring foliage, often worst after wet spells Scatter ferric phosphate pellets; hand-pick at dusk; mulch with grit around crowns to deter

Stems and leaves cut at ground level, leaving bare crowns — most damaging on newly planted specimens Use individual wire cloches or install perimeter rabbit fencing
