Chin Cactus pests — FAQ
What is eating my chin cactus?
Chin Cactus (Gymnocalycium baldianum) is a low-growing flowering houseplant susceptible to mealybugs tucked into its ribs and around blooms. Spider mites attack during hot, dry conditions. When moved outside to bloom, aphids may target flower stalks. Root mealybugs are a risk in damp compacted soil. Its smooth ribs make inspection easier than woolly cacti.
