Troubleshooting
Chagual problems — and how to fix them
Chagual (Puya chilensis) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root and crown rot
The primary threat in cool, wet climates. Plant on a slope or raised bed in sharply draining soil, and protect from winter waterlogging. Container plants should be moved under cover in wet winters in the UK.
Very slow growth and long time to flower
In cultivation flowering may take 10–20 years from seed. Maximising sun exposure and using a lean, well-draining substrate helps. Monocarpic — collect offsets before the mother plant dies.
Scale insects
Armoured scale may settle along leaf bases. Remove by hand in early stages; apply horticultural oil spray for heavier infestations. Inspect carefully given the fiercely spiny leaves.
Prevent chagual problems before they start
Most chagual issues are care-mismatch, not bad luck. Dial in the basics:
