What's eating my brazilian tree fern?

Brazilian Tree Fern, kept as a tropical specimen indoors or in a warm conservatory, is most commonly troubled by scale insects on its trunk and fronds. Spider mites attack the fronds in dry air. In outdoor tropical settings, caterpillars may chew young fronds. Regular inspection of the fibrous trunk is important.

Waxy brown or gray bumps embedded in the fibrous trunk and on frond midribs; yellowing fronds and honeydew Scrub trunk and fronds with a brush dipped in rubbing alcohol or horticultural soap; apply horticultural oil spray, repeating every 2 weeks

Fine webbing, stippling, and bronze discoloration on frond undersides, especially in dry or heated indoor air Raise humidity; shower fronds regularly; apply insecticidal soap or neem oil spray weekly

White cottony masses at the base of fronds and in fibrous trunk crevices; weakened new growth Treat directly with rubbing alcohol on a cotton swab; follow with neem oil spray every 7–10 days
