What's eating my columnea 'robin'?

Columnea 'Robin' is a trailing indoor hybrid with abundant small blooms, sharing the Gesneriaceae family's typical pest profile. Spider mites are the dominant threat in dry heated rooms. Mealybugs shelter in stem joints along its long trailing stems. Aphids appear on soft new growth. Regular humidity management and monthly stem inspections keep this cultivar healthy.

Stippled, faded leaves with webbing on undersides; foliage deteriorates quickly in low humidity or near heat vents Raise humidity; rinse foliage thoroughly; apply insecticidal soap or neem oil to all leaf surfaces every 5–7 days for three rounds

White cottony masses along trailing stems at leaf nodes; sap loss weakens the plant and reduces flower production Dab with 70% isopropyl alcohol; spray entire plant with neem oil weekly for 3–4 weeks; check new growth after treatment

Clusters of small soft insects on new shoot tips; curled or distorted leaves; honeydew residue Rinse with water; apply insecticidal soap to affected areas; repeat weekly until populations are eliminated
