What's eating my gold charm holiday cactus?

Gold Charm Holiday Cactus (Schlumbergera truncata 'Gold Charm') shares the same pest vulnerabilities as all Schlumbergera: mealybugs at segment joints, fungus gnats in wet soil, and spider mites in dry heated rooms. Its soft fleshy stems are more susceptible than desert cacti. Pale yellow blooms can mask early mealybug cotton — inspect closely.

White cottony tufts at stem segment joints; segments become limp and may drop; bud drop before flowering Treat each joint with an alcohol-dipped swab; repeat weekly; check soil surface for crawlers

Gnats hovering near soil; larvae damage shallow roots causing sudden wilting in otherwise healthy conditions Reduce watering frequency; top-dress with coarse horticultural grit; drench soil with Bti

Pale stippling and very fine webbing across flat stem segments, particularly in warm dry indoor air in winter Wipe with damp cloth; apply neem oil or insecticidal soap spray; increase humidity around the plant
