Troubleshooting
Immersed Stelis problems — and how to fix them
Immersed Stelis (Stelis immersa) 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.
Cold draughts causing spotting
Cold air from open windows or air conditioning vents hitting foliage causes irregular brown spots and leaf drop. Position away from draughts and maintain stable temperatures within the cool range.
Root desiccation on mounted plants
Mounted plants in warm or dry air can lose root moisture within hours. Check root colour — healthy roots are white to silver when dry, green when moist. Adjust misting frequency seasonally.
Scale insects
Brown or tan oval scale appear on leaf surfaces and rachis. Scrape off manually, then treat with horticultural oil spray. Repeat at 10-day intervals to catch emerging crawlers.
