Pink Rock Jasmine problems — and how to fix them
Pink Rock Jasmine (Androsace carnea) 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.
Winter cushion rot
The most frequent cause of plant loss. Water collecting in the hairy rosettes during cold, damp winters causes botrytis and bacterial rot. Grow in an alpine house through winter or protect with a glass pane to shed rain while maintaining airflow.
Cushion browning in heat
Extended hot, dry periods can cause browning of the central rosettes. Ensure the root run stays cool by planting in tufa or a deep scree bed; a light misting in the cool of the morning can help during extreme summer heat.
Root aphids
Subterranean aphids attack the root system, causing sudden wilting and yellowing despite adequate watering. Confirm by inspecting roots; treat with a systemic insecticide drench approved for ornamentals or discard and replace badly affected plants.
