Pruning Nandina in March: The Three-Tier Method for Berries

Perfect Timing for Maximum Impact

March is the ideal month to prune common nandina (heavenly bamboo). Done correctly, you'll get lush new foliage, summer flowers, and a brilliant fall berry display.

The Three-Tier Technique

Cut canes at three different heights to create a natural, layered look:

• ⅓ of canes at 12 inches high
• ⅓ of canes at 24 inches high
• ⅓ of canes at 36 inches high

What Happens Next

1. Spring: Each cut cane sprouts fresh foliage.
2. Late summer: Plants flower on new growth.
3. Late fall: Clusters of bright red berries appear.

Why This Works

Staggered heights ensure continuous foliage from ground to tip while promoting flowering wood at multiple levels. Avoid shearing into meatballs—that destroys the plant's graceful habit and reduces berries.
