Quesnel's Bromeliad problems — and how to fix them
Quesnel's Bromeliad (Quesnelia quesneliana) 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.
Stagnant tank causing crown rot
If the central cup is not flushed regularly, bacteria and algae accumulate and can rot the growing point. Flush and refill with fresh (ideally rainwater) every 3–4 weeks.
Mealybugs in the leaf axils
White cottony clusters may appear deep in the rosette. Remove manually with an alcohol-tipped swab and follow up with a dilute neem oil or insecticidal soap spray.
Failure to flower in low light
Without sufficient bright, indirect light, Quesnelia will not initiate a flower spike. Move to a brighter location; placing a ripe apple near the plant and covering with a clear bag for a week can encourage blooming via ethylene gas.
