What's eating my eastern cape cycad?

Cycad scale (Aulacaspis yasumatsui)

Signs: Masses of white armored scale colonize fronds, the caudex, and roots; causes rapid yellowing, frond collapse, and potential plant death.

Control: Spray all surfaces thoroughly with horticultural oil every 10–14 days; supplement with a systemic imidacloprid drench to protect roots and new growth.

Mealybugs

Signs: Fluffy white clusters at leaf bases and in the crown; sustained feeding weakens this already slow-growing plant.

Control: Remove manually with alcohol swabs; apply insecticidal soap or neem oil spray weekly for 3–4 weeks.

Scale insects (soft scale)

Signs: Soft, waxy bumps on frond rachises and stems; sticky honeydew and sooty mold indicate active infestations.

Control: Scrape off with a brush, treat with horticultural oil spray, and check monthly to catch any regrowth early.
