What's eating my bulbophyllum vaginatum?

Bulbophyllum vaginatum, a Southeast Asian miniature orchid grown in warm, humid indoor conditions, is most vulnerable to spider mites when humidity drops below ideal levels. Mealybugs tucked between the small pseudobulbs are a persistent secondary threat. Scale may appear on rhizomes. Keeping this species in a humid enclosure or terrarium naturally suppresses mite outbreaks.

Silvery stippling on small leaves and fine webbing; plants weaken quickly in dry conditions Boost humidity significantly, spray neem oil or insecticidal soap weekly; rinse foliage often

White waxy clusters hidden between the closely spaced pseudobulbs and at rhizome bases Use a fine cotton swab dipped in isopropyl alcohol to target colonies; follow with neem oil

Tan or brown bumps on rhizomes and pseudobulb bases; slow to notice but weaken the plant over months Scrape off with a toothpick or soft brush; apply horticultural oil and inspect fortnightly
