What's eating my geranium phaeum 'album'?

Geranium phaeum 'Album' shares the shade-loving habit of the species, making slugs and snails the dominant pest threat — wet, shaded borders are prime slug habitat. Vine weevil grubs can damage roots beneath the crown. White flowers may attract more aphid attention than darker-flowered forms but damage is usually minor.

Ragged holes and slime trails on foliage; new spring growth is most vulnerable in shaded moist positions Ferric phosphate pellets; biological control with Phasmarhabditis nematodes; hand-pick under boards placed near plants as traps

Notched leaf margins from adult beetles; white grubs eat roots and crowns causing sections to die Apply Steinernema kraussei nematodes in late summer to moist soil; remove and destroy any grubs found during division

Sticky colonies on tender shoot tips; honeydew can lead to sooty mold; generally minor on this species Dislodge with water; spray insecticidal soap if colonies grow; avoid high-nitrogen feeding which produces lush, aphid-attractive growth
