What's eating my geranium 'orion'?

Geranium 'Orion' is a large, long-flowering hybrid cranesbill for mixed borders. Vine weevil is the most serious pest, particularly for container-grown plants. Slugs and snails damage new foliage in spring and after rain. Aphids attack tender shoot tips but are rarely severe. Deer generally avoid it.

White root-feeding grubs cause collapse; adults leave smooth notches around leaf margins at night Apply Steinernema kraussei nematodes to moist soil in late summer; check for grubs when dividing or repotting

Ragged holes in young leaves and flower buds; slime trails confirm their presence Use iron phosphate pellets; water plants in the morning; mulch with grit; hand-pick at dusk

Colonies on growing tips distort new growth and deposit honeydew that encourages sooty mould Knock off with water; spray insecticidal soap; foster ladybirds and parasitic wasps in the garden
