Troubleshooting
Mahonia repens problems — and how to fix them
Mahonia repens (Mahonia repens) 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.
Mahonia rust
Orange-brown leaf pustules in humid, crowded patches; remove affected foliage and thin to improve airflow.
Winter leaf bronzing
Often mistaken for damage, the purple-bronze winter colour is normal and reverts to green in spring; no action needed.
Aggressive spread
Stolons can colonise beyond the intended area; edge the planting or remove runners to contain it.
Poor establishment in wet soil
Dislikes heavy, waterlogged ground and may rot or sulk; plant on free-draining sites for best results.
