What's eating my dracaena deremensis warneckii?

Dracaena Deremensis Warneckii is a popular striped-leaf indoor plant susceptible to spider mites, scale, and mealybugs — the classic trio for Dracaena in home environments. Spider mites are the most frequent offender, especially in centrally heated rooms in winter. Keep humidity up and wipe leaves monthly to catch infestations early.

Pale stippling and dulling of the white and grey leaf stripes; fine webbing on leaf undersides in dry, warm conditions Shower the plant thoroughly; apply neem oil or insecticidal soap weekly for three to four weeks; move away from heat sources and raise local humidity

Hard brownish bumps on stems and along leaf midribs; sticky honeydew on lower leaves; gradual yellowing and leaf drop Physically remove with a soft toothbrush dipped in soapy water; follow with horticultural oil spray; re-treat after 14 days

White fluffy residue in leaf axils and at stem nodes; growing tips may be distorted if mealybugs reach them Treat with isopropyl alcohol on a cotton swab; spray the entire plant with neem solution every 7–10 days; isolate the plant from others

Silver or bronze streaking along the leaf surface; tiny black frass dots; affected leaves develop a papery texture Remove and dispose of affected foliage; apply insecticidal soap or a spinosad-based spray; use blue sticky traps to assess pressure
