Pest identification
What's eating my heuffel's jovibarba?
Vine weevil
Signs: Adults leave ragged notches in leaf edges; C-shaped white grubs eat roots, causing the rosette to suddenly collapse and lift free from soil
Control: Apply biological control nematodes (Steinernema kraussei) to pots in spring or autumn when soil is above 5°C; use imidacloprid-based vine weevil compost drench for severe cases
Mealybugs
Signs: White cottony deposits at the base of tight rosette leaves, especially on indoor or greenhouse-kept plants
Control: Dab with a cotton swab soaked in 70% isopropyl alcohol; apply insecticidal soap spray; re-check after 7 days and repeat as needed
Aphids
Signs: Small colonies on emerging flower stems in summer; sticky honeydew and mild distortion of florets
Control: Pinch off affected stems or spray with insecticidal soap; outdoor plants often see natural predator control within 1–2 weeks
