Troubleshooting
Tiny Stelis problems — and how to fix them
Tiny Stelis (Stelis pusilla) 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.
Scale insects
Soft scale insects colonise the undersides of the fleshy leaves and ramicaul sheaths. Inspect monthly; remove with a cotton swab dipped in isopropyl alcohol or apply horticultural oil spray.
Root rot in poorly draining mix
Stelis pusilla roots are fine and sensitive to waterlogging. Use a free-draining medium and avoid large pots — a pot barely larger than the root mass is ideal to prevent sour, stale conditions.
Failure to flower indoors
Stelis pusilla blooms reliably with a slight seasonal cool-down (nights 10–14 °C) in autumn. Without this temperature cue, plants may produce only vegetative growth. Moving to a cool windowsill in autumn usually triggers blooming.
