What's eating my rodriguezia lanceolata?

Rodriguezia lanceolata, a compact epiphytic orchid, is most vulnerable to spider mites and mealybugs under typical indoor growing conditions. Dry air encourages mite outbreaks, while mealybugs colonize pseudobulb crevices. Scale occasionally appears on older canes. Maintain good airflow and humidity and inspect weekly to catch problems early.

Silvery stippling and fine webbing on leaf undersides; leaves turn yellow and drop if unchecked Increase ambient humidity, spray undersides of leaves with insecticidal soap or diluted neem oil every 5–7 days

Fluffy white deposits in pseudobulb sheaths and along stem junctions; honeydew attracts sooty mold Remove manually with alcohol-tipped swab, follow with neem oil drench; repeat every 10 days until clear

Hard or soft brown bumps on canes and leaf bases; gradual decline in vigor and leaf yellowing Scrub off with soft brush and soapy water; apply horticultural oil; severe cases may need systemic treatment
