What's eating my nannorrhops ritchiana?

Nannorrhops Ritchiana (Mazari Palm) is an exceptionally tough, drought-adapted palm with few serious pest problems. Scale insects and mealybugs are the most likely attackers, particularly on container plants. Its dense clustering habit can harbor mealybugs at the base of fronds. Spider mites may appear under very dry indoor or glasshouse conditions.

Crusty encrustations on petioles and frond bases; yellowing and weakened new growth Scrub off with alcohol-soaked cloth or cotton swab; spray with horticultural oil; repeat monthly until absent

White waxy cottony masses at frond bases and crown; honeydew and sooty mold on lower leaves Dab with isopropyl alcohol on a cotton bud; apply neem oil or insecticidal soap; isolate affected plants to prevent spread

Pale stippling and very fine webbing on leaflets, mainly in warm, dry, low-humidity conditions Raise humidity; mist foliage; apply neem oil spray; improve airflow around the plant
