Pest identification
What's eating my common blue violet?
Aphids
Signs: Clusters of insects on young growth; sticky residue, curled leaves, and reduced flowering.
Control: Spray with insecticidal soap or strong water jet; attract beneficial insects by planting nearby umbellifers.
Violet sawfly (Ametastegia pallipes)
Signs: Larvae chew leaf tissue between veins, producing a lace-like appearance; severe attacks strip plants bare.
Control: Hand-pick larvae; treat with pyrethrum if infestation is heavy; clear dead leaves in autumn.
Slugs and snails
Signs: Ragged holes in leaves and flowers; characteristic slime trails at soil level.
Control: Place iron phosphate bait around plants; hand-pick after rain or at night.
Rabbits
Signs: Stems clipped off neatly at or near soil level; entire rosettes may disappear overnight.
