What's eating my lime rickey heuchera?

Lime Rickey Heuchera's chartreuse foliage is primarily threatened by vine weevil larvae, which eat roots and cause the plant to collapse without warning. Adults notch leaf margins. Aphids attack tender new growth. Nematode soil drenches in late summer and regular root inspection when dividing are the best management strategies.

Notched leaf margins from adults; root destruction and crown collapse from soil-dwelling larvae Drench with beneficial nematodes (Steinernema kraussei) in August–September when soil is warm and moist

Soft-bodied insects on young stems and flower scapes; honeydew, sticky leaves, distorted tips Spray with insecticidal soap; blast off with water; avoid excessive nitrogen fertiliser that promotes soft growth

Holes in outer leaves close to the ground, most common in spring and autumn Apply iron phosphate slug bait; mulch away from the crown; hand-pick at night after rain
