What's eating my philodendron panduriforme?

Philodendron panduriforme, the fiddle-leaf philodendron, is most commonly troubled by spider mites and mealybugs indoors. The violin-shaped leaves are easy to inspect on both surfaces. Dry indoor air is the main trigger for mite outbreaks. Keep humidity above 50%, wipe leaves monthly, and apply neem oil at the first sign of pests.

Tiny pale yellow dots scattered across the fiddle-shaped leaves; fine webbing on undersides; leaves may become papery and drop in heavy infestations Shower the plant; maintain humidity; apply neem oil or insecticidal soap to both leaf surfaces weekly for 3–4 cycles

White cottony deposits at the narrow waist and lobes of the leaf, petiole bases, and stem nodes; honeydew; reduced vigor Spot-treat with isopropyl alcohol on a swab; spray the entire plant with insecticidal soap; retreat every 10 days until clear

Hard tan or brown bumps on stems and undersides of older leaves; leaves yellow and drop; sooty mold on lower foliage Scrape off visible scale; treat with horticultural oil; follow up monthly to eliminate crawlers before they mature
