What's eating my pearl plant?
Mealybugs
Signs: White cottony clusters in leaf axils and along the base; sticky honeydew residue on leaves.
Control: Dab individual bugs with a cotton swab dipped in 70% isopropyl alcohol; spray the whole plant with diluted neem oil or insecticidal soap every 7 days for 3 weeks.
Spider mites
Signs: Fine stippling or silvery streaks on leaf surfaces; tiny webs between leaves in heavy infestations.
Control: Raise humidity slightly, wipe leaves with a damp cloth, and apply diluted neem oil or insecticidal soap spray weekly until clear.
Fungus gnats
Signs: Larvae feed on fine roots in waterlogged soil; adults are a nuisance flying around the pot.
Control: Allow the soil to dry completely between waterings; apply a layer of horticultural grit on the soil surface; use yellow sticky traps to catch adults.
