Pruning nandina can be a daunting task, but with the right techniques, you can achieve a beautiful and lush yard. Nandina plants can grow quite tall, up to 10 feet, making them a great choice for hedges or screens.
To maintain a perfect yard, it's essential to prune your nandina regularly. Pruning in the late winter or early spring, before new growth begins, helps maintain the plant's shape and promotes healthy growth.
Remove any dead or damaged branches to prevent the spread of disease and encourage new growth. This will also help maintain the plant's natural shape and prevent it from becoming leggy.
Why Prune Nandina
You may never need to prune your Nandina if you've chosen a variety that's the right height for your space. However, if your Nandina has become overgrown and woody, with bare stems, pruning can help restore it to its former glory.
Pruning can also be necessary if your Nandina is blocking a nice view behind it. In this case, you can do a renewal pruning by removing just one or two of the tallest canes, or cutting out up to 1/3 of the oldest, tallest canes to the base. This will help maintain the plant's natural shape and promote new growth.
The Problem with Shearing
Shearing Nandina plants into shapes is a mistake, as they have a natural shape that should be preserved. The plants are multiple cane with compound leaves, composed of many oval-shaped leaves.
People try to prune them like a boxwood hedge, but boxwoods have a woody structure and tiny leaves, making them suitable for shearing. Nandina plants, on the other hand, are best pruned to maintain their natural shape.
Shearing Nandina plants into little round balls or squares can ruin their appearance, making them look sad and unattractive. These embarrassing examples can be seen in commercial and residential landscapes.
If your Nandina plants look this bad, it's best to hold off on pruning them until you can learn the proper techniques for pruning these plants.

Why Prune Nandina
Pruning your Nandina plant can be a bit intimidating, but it's actually quite straightforward. You don't have to prune your Nandina at all, especially if you've chosen a variety that's the right height for your space.
However, if your Nandina has gotten a bit out of hand, pruning can help restore its natural shape and promote healthy growth. This is especially true if your plant has become overgrown and woody, with bare stems.
One reason to prune your Nandina is to remove weak, broken, or crossing branches. These can be unsightly and even pose a risk to the rest of the plant.
Here are some reasons to prune your Nandina:
- Renewal pruning to remove old, tall canes
- Removing weak, broken, or crossing branches
- Pruning to maintain a specific height or shape
By pruning your Nandina, you can enjoy its many ornamental features throughout the year, including frothy white flowers in spring and summer, bright berries in autumn and winter, and leaves that turn red in the fall.
When to Prune
You can prune nandina any time of year in the Pacific Northwest, but I prefer to do restorative pruning in early spring or late May.
In most regions of the UK, late April is ideal for pruning nandina domestica. To avoid damaging new growth, it's best to prune in late spring after the last frosts.

Nandina plants can be pruned in mid-to-late spring, around April or May time, or in early autumn after flowering has finished.
If you need to prune a rogue branch, or want to take some for cuttings, or bouquets, remove the branch to the ground.
Here's a general guideline for pruning nandina:
You can also prune nandina any time of year in the Pacific Northwest, but it's best to remove canes for holiday decoration from a robust plant with lots of canes.
How to Prune
Pruning nandina plants is a simple process that can help maintain their shape and promote healthy growth. Cutting 1/3 of the canes to the ground is a great place to start.
To control the height of your nandina, select the tallest canes to remove. This will encourage new growth and a fuller plant. If you only have a few canes to work with, you can prune them at different heights to create a more balanced look.
Prune in late winter or early spring, as this is the best time to do so. Nandinas sprout from the branch tips, so pruning to the ground or in staggered sections below the main growth will encourage new growth.
Here's a step-by-step guide to pruning your nandina:
- Cut up to 1/3 of the canes all the way down to the soil level.
- Remove any rogue branches or take some for cuttings or bouquets.
- If you need to prune a small section, cut just above a leaf node.
- To achieve a compact and dense form, allow the plant to grow for 2 years, then cut it down to about 1/3 of its overall size in the third year.
By following these simple steps, you can keep your nandina looking its best and promote healthy growth.
Pruning Techniques
Cutting 1/3 of the canes to the ground is a simple and effective technique to get a better plant. This method allows you to control the height of the plant by selecting the tallest canes to remove.
You can also select another 1/3 of the canes and cut them at different heights. This technique is useful if you have a small number of canes, like three, and will create a fuller plant over time.
Prune in late winter or early spring for best results. This allows the plant to grow new canes and leaves in the spring.
To maintain a fuller plant, prune up to 1/3 of the canes all the way down to the soil level. This will encourage new growth and prevent the plant from becoming leggy.
Here are some specific pruning techniques to try:
- Cut two branches to the ground, two to 1/3 of the shrub's height, and up to 2/3 of the shrub's height if you have six canes.
- Remove a rogue branch to the ground if it's necessary.
After Pruning
You'll love the results after pruning your nandinas. The new growth will be bushy and full, and you'll have a much better plant.
Cutting 1/3 of the canes to the ground will get you a much better plant once the new canes sprout. This technique will also allow you to control the height of your nandinas by selecting the tallest canes to remove.
You can take pruning a step farther by selecting another 1/3 of the canes and cutting them at different heights. This will give your nandinas a fuller appearance.
Cutting your nandinas back to the ground isn't too late, even if they've been neglected for years. You can cut them off at ground level and they will sprout out and be bushy again.
After pruning, it's recommended to cut back the tallest 1/3 of the canes every mid-February. This will give your nandinas a new set of canes to grow from, replacing the ones that are getting bare from the bottom up.
Cutting heavenly bamboo, also known as nandina, to keep it bushy is worth the effort. It's an evergreen shrub that offers ornamental features in every season, including frothy white flowers in spring and summer, and bright berries in autumn and winter.
