Troubleshooting
Golden-flowered Rosularia problems — and how to fix them
Golden-flowered Rosularia (Rosularia chrysantha) 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.
Crown rot in wet or cold-wet conditions
Water accumulating in the rosette, especially combined with cold temperatures, rapidly causes crown rot. Ensure rosettes are protected from prolonged rain in winter; use an alpine house or cloche if needed.
Failure to flower
Insufficient sun is the most common reason for poor flowering. Move to a brighter, more open position outdoors or to the sunniest available windowsill to encourage blooming.
Mealybugs
Mealybugs may settle in the tight centre of rosettes or around the base. Remove with a cotton swab dipped in 70% isopropyl alcohol. Repeat weekly until all signs are gone.
