Troubleshooting
Sapphire Tower problems — and how to fix them
Sapphire Tower (Puya alpestris) 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 rot
The primary killer, especially in cool wet winters. Plant in sharply draining soil, avoid overhead winter irrigation, and protect from prolonged rain in temperate climates.
Scale insects
Armoured scale can colonise the leaf bases and undersides. Treat with a rubbing-alcohol-soaked cloth or an appropriate horticultural oil spray.
Failure to flower
Puya alpestris requires full sun and typically 6–8 years to reach flowering maturity. Insufficient light or youth are the most common reasons. Be patient and maximise sun exposure.
