What's eating my dracaena fragrans massangeana?

Dracaena Fragrans Massangeana (Corn Plant) is one of the most commonly grown indoor trees and is susceptible to several houseplant pests, especially spider mites and scale insects. Fluoride toxicity mimics pest damage with brown leaf tips, so rule that out first. Mealybugs target the cane joints; inspect these during routine care.

Yellow or bronze stippling across the broad strap leaves; fine webbing between leaves in dry indoor air — very common on Dracaena in winter Shower the plant to knock off mites; apply insecticidal soap or neem oil spray; repeat weekly for three weeks; raise humidity around the plant

Brown or tan oval bumps fixed to canes and midribs; sticky honeydew dripping onto lower leaves and floors Scrape off with a soft toothbrush; spray with horticultural oil or insecticidal soap; treat every 14 days until clear

White cottony deposits at cane nodes, leaf sheaths, and growing tips; sooty mould on honeydew residue Dab colonies with isopropyl alcohol; apply neem oil spray to the whole plant including cane surfaces; quarantine from other houseplants

Silver-streaked or scarred patches on the yellow centre stripe; tiny dark frass specks visible on leaf surfaces Remove heavily affected leaves; spray with insecticidal soap or spinosad-based product; use blue sticky traps to monitor
