What's eating my golden dragon?

Philodendron 'Golden Dragon' is most vulnerable to spider mites and mealybugs indoors. Check the leaf undersides and stem joints regularly for webbing or white fluff. Dry indoor air and dust on leaves encourage mites. Wipe leaves monthly and maintain humidity above 50% to stay ahead of infestations.

Fine stippling on leaves, thin webbing on undersides and between stems; leaves yellow and drop in heavy infestations. Isolate the plant, spray undersides with a strong water jet, then apply neem oil or insecticidal soap weekly for 3–4 weeks. Raise humidity to deter re-infestation.

White cottony clusters at stem joints and leaf axils; sticky honeydew leads to sooty mould and stunted new growth. Dab individual clusters with a cotton swab dipped in 70% isopropyl alcohol. Follow up with neem oil spray every 7–10 days until clear.

Brown or tan waxy bumps on stems and midribs; sap removal weakens growth and causes yellowing. Scrape off with a soft toothbrush, wipe with alcohol-soaked cloth, then treat with horticultural oil spray monthly.
