Troubleshooting
Persian Rosularia problems — and how to fix them
Persian Rosularia (Rosularia persica) 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.
Root rot
Excess moisture, especially in cool temperatures, quickly causes basal rot. Always use free-draining soil and pots with drainage holes; water sparingly in winter.
Mealybugs
These hide in tight rosette centres. Dab with isopropyl alcohol on a cotton swab and follow up with neem oil spray to prevent recurrence.
Rosette etiolation
Low winter light causes lanky, open rosettes. Supplement with a full-spectrum grow light from November to March if natural light drops below 4 hours daily.
