What's eating my toffee twist sedge?

Toffee Twist Sedge is largely pest-resistant, but slugs and snails are the main threat in damp conditions, rasping leaves near the base. Aphids occasionally colonise new growth, and vine weevil grubs can damage roots in containers. Deer and rabbits generally avoid this ornamental sedge.

Irregular ragged notches along leaf margins, especially at the clump base; slime trails visible at night or after rain. Apply iron phosphate pellets around the clump; use beer traps; remove debris where slugs shelter. Hand-pick at night.

Clusters of soft-bodied insects on new shoots causing distorted, sticky growth; honeydew may attract sooty mold. Knock off with a strong water jet; apply insecticidal soap or neem oil spray if colonies persist.

Notched leaf margins from adult beetles; more seriously, C-shaped white grubs eat roots, causing wilting and plant collapse in pots. Apply nematodes (Steinernema kraussei) to moist soil in late summer; use vine weevil-specific compost in containers.
