What's eating my schismatoglottis prietoi?

Schismatoglottis prietoi is a rare Southeast Asian aroid grown mainly as an indoor collector's plant. Like most aroids, it is most susceptible to spider mites in dry air, along with mealybugs in leaf axils and scale on stems. Root mealybugs can go undetected until the plant wilts. Maintain high humidity and inspect monthly.

Fine pale stippling on leaf surfaces; dull appearance and premature leaf yellowing; webbing under leaves in severe cases. Keep humidity above 60%, wipe foliage with a damp cloth, and apply neem oil or insecticidal soap spray every 7 days.

White cottony clusters in tight leaf axils and at root crown; can spread to roots causing unexplained wilting. Spot-treat above-ground colonies with isopropyl alcohol; drench soil with diluted neem oil to reach root mealybug populations.

Brown waxy bumps on stems and along midribs; sap extraction weakens growth and triggers yellowing leaves. Scrape off manually with a soft toothbrush, apply horticultural oil spray, and repeat after 14 days to catch crawlers.
