Pest identification
What's eating my lysimachia nummularia?
Aphids
Signs: Colonies on shoot tips cause curling, yellowing, and honeydew build-up that attracts ants.
Control: Dislodge with water jets; introduce natural predators; apply insecticidal soap if infestations are heavy.
Slugs and snails
Signs: Graze leaves and stems at soil level overnight, leaving slime trails and ragged holes.
Control: Hand-pick at dusk; set beer traps; use iron-phosphate slug pellets around the planting.
Vine weevil (Otiorhynchus sulcatus)
Signs: C-shaped grubs eat roots in containers, causing sudden wilting and plant collapse.
Control: Apply nematode drench (Steinernema kraussei) to moist compost in late summer or autumn.

What is eating my lysimachia nummularia?
Lysimachia nummularia (creeping Jenny) is a low-growing flowering ground cover. Aphids cluster on young shoots, causing leaf curl and sticky deposits. Slugs and snails graze foliage at soil level, and vine weevils can damage roots in containers. The plant is generally vigorous and pest-resistant, but dense mats trap moisture and encourage molluscs.
