How to prune nandina harbour dwarf

Early spring before new growth flushes. Use bypass pruners or loppers to remove dead canes at ground level and selectively thin 1–2 oldest canes per clump each year. For overgrown plants, a hard cut of all canes to 6–12 inches can rejuvenate — this is a last resort, done in early spring only.

It needs very little pruning. Each spring, remove any dead or winter-burned stems at ground level. Occasionally cut out the oldest canes to encourage fresh, colorful new growth. Never shear it flat — that ruins its graceful spreading texture.
