What's eating my baltic blue pothos?

Baltic Blue Pothos (Epipremnum pinnatum 'Baltic Blue') is a hardy indoor plant but still falls prey to the usual aroid pests. Spider mites and mealybugs are the most common, while fungus gnats affect the roots when soil stays too moist. Its vigorous growth means it can handle light infestations, but heavy ones slow the fenestration development that makes this cultivar desirable.

White cottony masses at stem nodes, leaf axils, and along trailing vines; honeydew and sooty mold; leaves yellow and fenestrations may reduce on affected stems. Spot-treat with 70% isopropyl alcohol on cotton swabs. Spray with neem oil or insecticidal soap every 7 days for 3–4 cycles. Remove and pot separately any cuttings that appear infested.

Pale stippling and a dusty, dull appearance on leaf surfaces; fine webbing on undersides; more common in dry, centrally heated rooms in winter. Increase humidity and rinse the plant under the shower. Apply neem oil or insecticidal soap to both leaf surfaces every 5–7 days for at least 3 treatments.

Larvae damage fine root hairs causing wilting and yellowing; adult gnats are a nuisance, hovering around the soil surface and pot drainage holes. Allow the top 2 inches of soil to dry before re-watering. Use Bacillus thuringiensis israelensis (Bti) as a soil drench or top-dress with gnat-barrier sand. Yellow sticky traps catch adults.
