Long-Stalked Cranesbill problems — and how to fix them
Long-Stalked Cranesbill (Geranium columbinum) 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.
Failure to establish on heavy soils
On clay or waterlogged ground, seedlings often damp off or fail to persist. Improve drainage by incorporating coarse grit before sowing, or grow in raised beds or gravel gardens.
Competition from vigorous vegetation
As a slender annual, G. columbinum is easily smothered by coarser perennials or grasses. Maintain a semi-open, disturbed or grazed habitat; use as a gap-filler in thin turf or gravel.
