What's eating my stephania suberosa?
Spider mites
Signs: Stippled, pale leaf surface with fine webbing; foliage yellows and drops in severe cases
Control: Spray vines with insecticidal soap or neem oil solution every 5–7 days; avoid overly dry air
Mealybugs
Signs: White waxy clusters at stem nodes; honeydew deposits attract sooty mold on the caudex
Control: Spot-treat with 70% isopropyl alcohol on a swab; follow with neem oil spray across all foliage
Scale insects
Signs: Flat or dome-shaped brown bumps on caudex and stems; sap loss weakens stored energy reserves
Control: Scrape away physically; apply horticultural oil; inspect the caudex at the start of each growing season

Stephania Suberosa pests — FAQ
What is eating my stephania suberosa?
Stephania suberosa, a caudex-forming houseplant, is most prone to spider mites on its seasonal foliage and mealybugs at stem joints. The corky caudex can harbour scale during dormancy. Hot, dry indoor air amplifies mite pressure significantly; maintaining moderate humidity helps keep populations low.
