Trailing Rock Jasmine problems — and how to fix them
Trailing Rock Jasmine (Androsace lanuginosa) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Fungal rosette rot
Dead or dying rosettes within the mat trap moisture and act as an entry point for Botrytis or collar rot; remove dead material promptly and ensure good air circulation around the trailing stems.
Slugs and snails
Young shoots and the soft hairy foliage are attractive to slugs in damp weather; use iron phosphate pellets around the base or apply biological nematode control (Phasmarhabditis hermaphrodita) when soil temperature exceeds 5°C.
