What's eating my geranium 'nimbus'?

Geranium 'Nimbus' is a trailing, finely cut-leaf hybrid cranesbill. Its main threats are vine weevil grubs (especially in pots), slugs on new growth, and aphids on tender shoot tips. Its delicate texture makes slug damage especially visible. Deer and rabbits generally avoid true hardy geraniums.

Root destruction by larvae causes sudden plant wilting; adults notch the finely cut leaf margins at night Drench with Steinernema kraussei nematodes in late summer; lift and inspect roots at division; gritty compost slows weevil egg-laying

Holes and tattered edges on delicate foliage and flowers, especially in cool, wet conditions Apply iron phosphate pellets; improve air circulation to reduce damp; hand-pick after dark

Clusters on new shoot tips cause curled, distorted foliage and sticky honeydew Remove with water jets or insecticidal soap; avoid excess nitrogenous feed; rely on natural predator populations where possible
