What's eating my small-flowered alumroot?

Vine weevil

Signs: Adult notch-feeding on leaf margins; larvae eat roots and crown, causing sudden wilting and plant death

Control: Beneficial nematode drench in late summer and early autumn; inspect pot compost; avoid overwatering which favors grub survival

Slugs and snails

Signs: Ragged holes in leaves and growing points; slime trails; worst in cool, moist conditions

Control: Iron phosphate pellets; coarse grit around crowns; hand-pick at night after rain

Deer

Signs: Rosettes browsed down to crown level; repeated grazing weakens or kills plants

Control: Repellent sprays reapplied after rain; physical fencing; site in areas with lower deer pressure

Small-flowered alumroot pests — FAQ

What is eating my small-flowered alumroot?

Small-flowered alumroot faces the same core pest pressures as the Heuchera genus: vine weevil grubs silently destroy roots, slugs shred foliage in damp sites, and deer browse rosettes readily. Its fine-textured leaves may also attract foliar nematodes in wet conditions. Vine weevil is the most damaging threat, especially in containers.
