Pest identification
What's eating my chagual?
Aphids
Signs: Dense colonies on emerging flower stems; honeydew leads to sooty mold and attracts ants
Control: Spray with a strong jet of water; apply insecticidal soap or neem oil; remove ant trails that protect aphid colonies
Scale insects
Signs: Armored brown bumps on the woody stem base and lower leaf ribs; slow plant decline if untreated
Control: Scrape off mechanically; apply horticultural oil or neem oil and repeat every 10–14 days for 3 cycles
Slugs and snails
Signs: Chewed, ragged edges on soft young offset leaves before spines develop; slime trails present
Control: Hand-pick at night; use iron phosphate pellets around the base; improve drainage to reduce damp hiding spots

Chagual pests — FAQ
What is eating my chagual?
Chagual is a giant armed Puya from Chile reaching several meters tall. Its fierce spines deter large animals, but aphids readily attack flower stalks, and scale insects colonize the woody stem base. In its native range, humming birds visit flowers harmlessly. Slugs may nibble young offset leaves before spines harden.
