Can You Divide Blueberry Bushes

Yes, you can divide blueberry bushes, and it’s actually one of the most rewarding ways to multiply your berry harvest without spending a dime at the nursery.
 
If you’ve been wondering if you can divide blueberry bushes the same way you split hostas or daylilies, the answer is a little more nuanced but totally doable.
 
Blueberry bushes don’t grow from a single central crown the way many perennials do, so dividing them takes a slightly different approach.
 
Instead of slicing through one root ball, you’re separating suckers, runners, or entire sections of the root system that have their own stems.
 
In this post, we’ll walk through whether you can divide blueberry bushes, when to do it, how to do it step by step, and the mistakes that can kill your new plants.
 
Let’s dig in.
 

Can You Divide Blueberry Bushes? Here’s the Real Answer

Yes, you can divide blueberry bushes, but it helps to understand how they grow first.
 
Blueberries spread through underground stems called rhizomes and produce new shoots, often called suckers, around the base of the main plant.
 
These suckers are essentially baby blueberry bushes attached to the parent, and they’re your best bet for division.
 
When you divide blueberry bushes, you’re not cutting one plant in half; you’re separating these natural offshoots into new, independent plants.
 
This is why dividing blueberries works so well, since each sucker already has roots and stems of its own.
 

1. Blueberries Spread by Suckers and Rhizomes

Unlike raspberries that send out long canes, blueberry bushes expand slowly underground.
 
The rhizomes creep outward and push up new stems, which is why an older bush often looks like a cluster instead of a single trunk.
 
Those clusters are perfect candidates for division.
 

2. Each Division Needs Roots and Stems

For a divided section to survive, it needs both a healthy root mass and at least one or two strong stems.
 
If you pull up a sucker with barely any roots, it likely won’t make it.
 
So when you divide blueberry bushes, always check that the section you’re removing has a solid root system.
 

3. Dividing Is Easier Than Starting from Seed

Growing blueberries from seed takes years and the results are unpredictable.
 
Dividing blueberry bushes gives you a genetic clone of the parent, so you get the same tasty berries much faster.
 
That’s a big reason so many gardeners choose to divide instead of propagate from scratch.
 

When to Divide Blueberry Bushes

Timing matters a lot if you want your divisions to thrive.
 
The best time to divide blueberry bushes is during dormancy, either in late winter or early spring before new growth starts.
 
Early fall can also work in mild climates, giving roots time to settle before winter.
 
Avoid dividing during the heat of summer or while the bush is fruiting, since stress can kill the new plants.
 

1. Late Winter or Early Spring

This is the gold standard window for dividing blueberry bushes.
 
The plant is asleep, so shock is minimal, and it has the whole growing season to recover.
 
Just wait until the worst of the frost has passed.
 

2. Early Fall in Mild Climates

If your winters are gentle, early fall division works nicely.
 
The soil is still warm, which encourages new root growth before the cold sets in.
 
Just make sure to water consistently through the fall.
 

3. Avoid Dividing During Fruiting

Never divide blueberry bushes while they’re loaded with berries.
 
The plant is pouring energy into fruit, not roots, so divisions will struggle.
 
Wait until the harvest is done and the bush goes dormant.
 

How to Divide Blueberry Bushes Step by Step

Dividing blueberry bushes isn’t complicated, but it does take a little patience and the right tools.
 
Here’s how to do it without damaging the parent plant.
 

1. Water the Bush a Day Before

A well-watered bush is easier to dig around and less stressed by the process.
 
Give it a deep soak the day before you plan to divide.
 

2. Dig Around the Sucker or Section

Use a sharp spade to dig a circle around the sucker you want to remove.
 
Go wide enough to capture the roots, usually about 6 to 8 inches from the stem.
 
Then lift the whole root ball gently.
 

3. Separate with a Clean Cut

If the section is still attached to the parent, cut it free with a clean, sharp knife or pruners.
 
Make sure each division has roots and stems.
 
This is the moment that determines whether you can divide blueberry bushes successfully or not.
 

4. Replant Immediately

Blueberry roots hate drying out, so replant right away.
 
Choose a spot with acidic soil and full sun, then water deeply.
 
Mulch with pine bark or sawdust to keep moisture in.
 

So, Can You Divide Blueberry Bushes?

You can divide blueberry bushes, and doing it during dormancy gives you the best chance of success.
 
Just remember that blueberries spread by suckers and rhizomes, so you’re separating rooted sections rather than splitting one crown.
 
Water well, replant fast, and keep the soil acidic.
 
Do that, and you’ll turn one blueberry bush into several without spending a cent.
