What's eating my syagrus romanzoffiana?

Palm aphids (Cerataphis brasiliensis)

Signs: Heavy honeydew deposits, sooty mold blackening on lower fronds, distorted new growth under heavy pressure

Control: High-pressure water spray to dislodge colonies; insecticidal soap or neem oil applied to all frond surfaces; introduce natural predators

Armored scale (Diaspididae spp.)

Signs: Hard brown or white encrustations on petioles and frond bases; progressive yellowing and frond dieback

Control: Horticultural oil spray applied comprehensively; scrub heavy infestations; repeat monthly

Spider mites (Tetranychus urticae)

Signs: Stippled, bronzed leaflets with delicate webbing on undersides; most severe during hot, dry periods

Control: Regular irrigation to reduce plant stress; neem oil or miticide spray; avoid applying broadspectrum insecticides that kill predatory mites

Rats and squirrels

Signs: Fruit gnawed from clusters; gnaw marks on seed husks below the tree

Control: Install trunk rat guards; remove fallen fruit promptly; trim overhanging branches that allow roof-rat access
