Blue-Flowered Air Plant problems — and how to fix them
Blue-Flowered Air Plant (Tillandsia caerulea) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Base rot
The most common problem; caused by water pooling at the base or poor airflow after watering. The base turns brown or black and feels mushy. Ensure the plant dries fully within one hour of watering and is never mounted in a moisture-retaining vessel.
Mealybugs and scale insects
White waxy cottony deposits (mealybugs) or tiny shell-like bumps (scale) appear on leaves. Remove manually with a cotton bud dipped in diluted isopropyl alcohol, then rinse. Plants stressed by low humidity or inadequate light are most susceptible.
