Troubleshooting
Two-Ranked Air Plant problems — and how to fix them
Two-Ranked Air Plant (Tillandsia didisticha) 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.
Root rot from moisture retention
If mounted in a way that traps water between the leaves or base, rot can develop quickly. Ensure the mount allows free drainage, always dry the plant promptly after watering, and never house it in a closed terrarium.
Scale insects
Tiny shell-like bumps on leaf undersides indicate scale. Remove by scraping off gently with a soft brush and treating the area with diluted neem oil or isopropyl alcohol; repeat weekly until clear. Improve airflow to reduce risk of re-infestation.
