Pruning a nandina shrub also improves air circulation through the center of the plant, which helps prevent fungal issues.
 
And if you’ve been pruning a nandina shrub annually, you’ll notice it produces better fall color and more berries, which is a lovely bonus.
 
So, pruning a nandina shrub is not just about keeping it tidy, it’s about promoting long-term vigor and beauty.
 

When Is the Best Time to Prune a Nandina Shrub

Pruning a nandina shrub during this dormant period is ideal because the plant is resting and won’t be stressed by the cuts.
 
If you live in a mild climate, you can even prune a nandina shrub in early fall, but late winter is your safest bet.

Another good time to prune a nandina shrub is right after a hard frost has damaged some of the tips, so you can clean up the dead foliage.
 
Just remember, pruning a nandina shrub at the right time ensures you don’t sacrifice the seasonal display of red and orange leaves.
 
So mark your calendar for late winter, and your nandina shrub will thank you with robust spring growth.

If you prefer a more natural, airy appearance, then selective thinning is how you prune a nandina shrub gently.
 
This method involves removing about one-third of the oldest, tallest canes each year by cutting them right at the soil line.
 
When you prune a nandina shrub selectively, you never cut the tops off the remaining canes, which keeps the plant’s natural arching shape.
