Pest identification
What's eating my pachystachys lutea?
Whitefly
Signs: Clouds of tiny white flies erupt when foliage is touched; pale nymphs coat leaf undersides; honeydew causes sooty mold on the decorative golden bracts.
Control: Hang yellow sticky traps; spray leaf undersides thoroughly with insecticidal soap, pyrethrin, or neem oil weekly; use Encarsia formosa in glasshouse settings.
Spider mites
Signs: Fine, pale mottling across large leaves; leaves yellow and drop prematurely; webbing between leaves and stems in severe dry-air infestations.
Control: Increase humidity; wash foliage and apply insecticidal soap or neem oil every 5–7 days; move plant away from heat sources.
Aphids
Signs: Soft-bodied insects clustered on new shoots, leaf undersides, and around the bright yellow bracts; growth becomes distorted and sticky.
Control: Remove by hand or water blast; treat with insecticidal soap or neem oil spray weekly until resolved.
Scale insects
Signs: Brown shell-like bumps on older woody stems; continuous sap feeding weakens plants, causing leaf yellowing and reduced flowering.
Control: Scrape off manually and apply horticultural or neem oil; for persistent infestations use systemic neem oil drenches or wipe stems with alcohol.
