What's eating my geranium cinereum 'ballerina'?

Geranium cinereum 'Ballerina' is a compact alpine cranesbill grown in borders and rock gardens. Vine weevil is the chief threat, with grubs destroying roots of these small plants rapidly. Slugs damage soft foliage in wet weather, and aphids occasionally target new shoots in spring.

Sudden wilting as root-feeding grubs kill the root system; adult beetles notch leaf margins at night Apply biological nematode drench (Steinernema kraussei) in late summer to moist soil; repot containers regularly to check for grubs

Irregular holes in leaves and petals at ground level; slime trails on soil and foliage Apply iron phosphate slug pellets around plants; hand-pick after dark; mulch with sharp grit to deter slugs in rock gardens

Dense colonies on soft shoot tips cause leaf curl and deposit sticky honeydew Pinch off affected tips; spray with insecticidal soap or neem oil; introduce or attract natural predators
