What's eating my dolce blackcurrant heuchera?

Heuchera 'Dolce Blackcurrant' is most threatened by vine weevil, whose larvae devour roots and cause sudden collapse. Vine weevil adults notch leaf edges. Vine weevil nematode drenches are the key defense. Aphids cluster on new growth and foliar stems; slugs may nibble young foliage in wet conditions.

Adults cut U-shaped notches in leaf margins; larvae destroy roots, causing wilting and plant death Apply Steinernema kraussei nematodes to moist soil in late summer or early autumn; check roots when dividing

Clusters of small insects on new growth and flower stems; sticky honeydew, distorted shoots Knock off with a strong water spray; apply insecticidal soap or neem oil; encourage ladybirds

Ragged holes in young or outer leaves, especially after wet nights Use iron phosphate pellets around the crown; clear debris to reduce shelter for slugs
