What's eating my philodendron silver sword?

Philodendron Silver Sword's silvery-blue foliage is most commonly damaged by spider mites, which are drawn to the warm indoor conditions this tropical prefers. Mealybugs hide along the climbing stem and in new leaf sheaths, scale can appear on aerial roots and stems, and thrips occasionally scar the metallic leaf surface.

Tiny pale flecks dulling the metallic silver-blue sheen; fine webbing on undersides; leaves yellow and curl Increase humidity, shower the foliage, apply neem oil or insecticidal soap spray every 7 days for 3–4 cycles

White fluffy colonies in new leaf sheaths, at stem nodes, and around aerial roots Swab with 70% isopropyl alcohol; follow with neem oil spray and soil drench to catch root mealybugs; repeat weekly

Brown shell-like bumps on stems and aerial roots; reduced growth and yellowing lower leaves Scrape scales off with a soft cloth or toothbrush; apply horticultural oil or neem oil; re-treat after 10 days

Silvery-white rasping scars on the leaf surface; tiny black droppings on new growth Remove affected leaves, apply spinosad or insecticidal soap; use blue sticky traps to monitor and capture
