Troubleshooting
Elephant Garlic problems — and how to fix them
Elephant Garlic (Allium ampeloprasum var. ampeloprasum) 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.
Rounds instead of split bulbs
Cloves planted late or grown without enough winter cold form a single undivided 'round' rather than a segmented bulb. Plant in autumn and replant rounds the next year to get a proper bulb.
Rust
Allium rust shows as orange pustules on the leaves in wet seasons, weakening growth and reducing bulb size. Space plants for airflow, rotate, and remove badly affected leaves.
Clove rot over winter
Cloves in cold waterlogged soil rot before sprouting. Plant into well-drained or raised beds and avoid heavy soils that stay wet through winter.
White rot
The persistent soil fungus that attacks all alliums rots the bulb base and kills plants. Use a long rotation and never plant into ground with a known white-rot history.
