Troubleshooting
Sempervivum 'Pacific Blue Ice' problems — and how to fix them
Sempervivum 'Pacific Blue Ice' (Sempervivum 'Pacific Blue Ice') 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.
Faded colour and lost bloom
The frosty blue and lavender tones need full sun and cool conditions; the powdery bloom rubs off if handled. In shade or with feeding the rosettes green over — increase light and minimise touching the leaves.
Root and crown rot
Overwatering or heavy soil rots the plant, the leading cause of failure. Use a gritty mix, water only when fully dry, and keep nearly dry in winter.
Etiolation
Low light stretches and pales the rosettes. Move to the brightest spot or supplement with a grow light to maintain a tight, well-coloured rosette.
Mealybugs and vine weevil
Mealybugs nest among the leaves and weevil grubs chew roots. Inspect the crown and rootball, treat with diluted alcohol or a suitable systemic, and keep airflow good.
