Jungfrau Saxifrage problems — and how to fix them
Jungfrau Saxifrage (Saxifraga cotyledon) 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.
Crown rot after flowering
The parent rosette is genetically programmed to die after setting seed; this is normal monocarpic behaviour, not disease — ensure offset rosettes are present before and after bloom. Wet winter conditions accelerate unexpected pre-flower crown rot.
Aphids on flowering stems
Greenfly frequently colonise the tall flower panicles in late spring; use a targeted insecticidal soap spray to protect the show stem without harming ground beetles and other beneficials around the rock garden.
