Troubleshooting
Geranium cantabrigiense problems — and how to fix them
Geranium cantabrigiense (Geranium cantabrigiense) 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.
Slow establishment
Mats can be slow to knit together in the first year. Plant closer-spaced and water well to speed coverage.
Rhizome rot in wet soil
Surface rhizomes rot in waterlogged ground. Ensure sharp drainage and avoid heavy, poorly drained sites.
Short single flowering season
Unlike rebloomers it flowers mainly once in early summer. It does not respond to cut-back with a second flush, so value it for foliage too.
Crowding out delicate neighbours
Its dense mat can smother small plants. Edge it back annually where it meets choicer specimens.
