Troubleshooting
Sanguisorba obtusa problems — and how to fix them
Sanguisorba obtusa (Sanguisorba obtusa) 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.
Foliage scorch in dry soil
Leaf edges brown and the plant looks tired when the ground dries out; the cure is consistent moisture and a moisture-retentive mulch rather than light surface watering.
Floppy stems
Over-rich feeding or too much shade produces lax stems that splay open after rain. Grow in full sun and stake or grow through neighbouring perennials for support.
Powdery mildew
A grey-white coating can appear on foliage in dry, crowded conditions late in the season. Improve air movement, keep roots moist and remove badly affected leaves.
Self-seeding spread
Plants can seed around freely in suitable soil. Deadhead spent spikes before seed sets if you want to limit volunteers, or lift unwanted seedlings while small.
