What's eating my hoya krimson princess?

Hoya carnosa 'Krimson Princess' is most at risk from mealybugs, which love the waxy stems and leaf joints where this slow-growing vine is hard to inspect. Spider mites attack in dry conditions, and scale may cluster on woody older stems. Consistent monitoring is essential — infestations can persist for months undetected.

White cottony masses at nodes, petioles, and in the curled new spathes; leaves yellow and plant weakens slowly Dab every visible bug with 70% isopropyl alcohol; follow with neem oil spray; repeat weekly; the waxy leaf surface resists penetration so thorough coverage is critical

Stippling and faint webbing on leaf undersides, particularly on the cream-variegated sections which show damage more clearly Increase humidity around the plant; wipe leaves; apply insecticidal soap or neem oil spray every 5–7 days for 3 weeks

Hard brown or soft cottony bumps on stems and petioles; slow decline and honeydew deposits Scrape off with a soft toothbrush, then treat with 70% isopropyl alcohol and follow with horticultural oil; repeat fortnightly
