What's eating my blue echeveria?
Mealybugs
Signs: White cottony masses tucked between rosette leaves; honeydew deposits; stunted growth
Control: Target each colony with an alcohol-soaked cotton swab to protect the glaucous coating; use systemic drench for severe infestations
Spider mites
Signs: Fine webbing on leaf undersides; pale or silvery stippling across leaf surfaces in dry conditions
Control: Wipe affected leaves gently; apply insecticidal soap avoiding the farina; raise humidity around the plant
Fungus gnats
Signs: Flies around pot; larval feeding on roots in compacted wet soil causes yellowing and wilt
Control: Use a fast-draining cactus mix; water only when bone dry; apply Bti drench to eliminate larvae
