Troubleshooting
Nandina Firepower problems — and how to fix them
Nandina Firepower (Nandina domestica 'Firepower') 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.
Loss of red colour
Foliage stays green in too much shade or with excess nitrogen fertiliser. Move to full sun and reduce feeding for vivid winter reds.
Leaf scorch
Harsh, dry winter wind or sudden cold can brown leaf margins. Site in a sheltered spot and water before hard freezes in exposed gardens.
Chlorosis (yellowing leaves)
Pale, yellow leaves with green veins indicate iron deficiency, usually from alkaline or waterlogged soil. Improve drainage and apply chelated iron.
Sparse, leggy form
Older 'Firepower' can thin at the base; though dwarf, a light spring trim of the tallest canes encourages dense, compact regrowth.
