Troubleshooting
Nandina Obsessed problems — and how to fix them
Nandina Obsessed (Nandina domestica 'Seika') 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.
Weak red flushes
Shade and excess nitrogen suppress the vivid new-growth colour. Move to full sun and limit feeding to restore the bright red flushes.
Leaf scorch in winter
Cold, drying winds can brown leaf edges in exposed sites. Provide shelter and ensure plants are watered going into freezing weather.
Chlorosis
Yellowed leaves with green veins signal iron deficiency on alkaline or waterlogged soil. Improve drainage and apply chelated iron.
Legginess if neglected
Skipping pruning lets stems thin and stretch. A light spring trim of the tallest canes keeps 'Obsessed' compact and well-branched.
