Troubleshooting
Three-awn Trisetella problems — and how to fix them
Three-awn Trisetella (Trisetella triaristella) 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.
Heat stress
Temperatures above 22°C cause rapid decline. Move to the coolest spot in the home, ideally near an air conditioning vent or a cool basement window.
Root desiccation
Without pseudobulbs, roots dry out quickly. Increase watering frequency and humidity immediately if roots look shrivelled.
Fungal crown rot
High humidity combined with poor airflow allows rot to set in. Use a small fan and avoid getting water trapped between the leaves.
Spider mites
Thrive in stagnant warm air. Raise humidity, improve airflow, and treat with insecticidal soap spray if found.
Failure to bloom
Cool-growing requirement not being met. Ensure nighttime temperatures below 15°C to initiate flowering.
