Yes, you can divide blueberry bushes, and it’s actually one of the easiest ways to multiply your berry harvest without spending a dime at the nursery.
If you’ve ever looked at a big, healthy blueberry bush and wished you had more just like it, division is your answer.
The process involves separating the root system into smaller sections, each with its own stems and roots, so every new piece can grow into a full bush.
It’s a bit like splitting a clump of daylilies, except you’re working with something that rewards you with fruit.
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 aftercare that keeps your new plants thriving.
Let’s dig in.
Why You Can Divide Blueberry Bushes
You can divide blueberry bushes because they grow from a network of shallow roots and crown buds that naturally send up new stems.
Here’s why this works so well:
1. Blueberries Spread Through Rhizomes and Suckers
Blueberry bushes don’t just grow from a single trunk.
They expand outward by sending up suckers from the root crown and underground stems called rhizomes.
This means a mature bush is essentially a cluster of connected plants, and each cluster can survive on its own once separated.
That’s the core reason you can divide blueberry bushes successfully.
2. They Have a Shallow, Fibrous Root System
Blueberry roots sit in the top 12 to 18 inches of soil, which makes them easier to lift and separate than deep-rooted shrubs.
Because the roots are fine and fibrous, they recover quickly when you divide blueberry bushes, as long as you keep them moist.
3. Division Rejuvenates Older Bushes
An old, crowded blueberry bush often produces smaller berries because the stems compete for light and nutrients.
When you divide blueberry bushes, you thin out that congestion and give each section room to breathe.
The result is often bigger fruit and stronger growth on both the original plant and the new divisions.
When to Divide Blueberry Bushes
Timing is everything if you want your divided bushes to survive and thrive.
1. Late Winter or Early Spring
The best time to divide blueberry bushes is while they’re still dormant, just before new growth pushes out.
In most climates, that means late winter to early spring, once the ground thaws but before buds break.
2. Avoid Dividing in Summer Heat
Never divide blueberry bushes in the middle of summer.
The stress of heat plus disturbed roots is usually too much, and your divisions may not survive.
3. Fall Is a Risky Second Choice
You can divide blueberry bushes in early fall in mild climates, but the plants need time to establish roots before frost.
Spring remains the safer bet for most gardeners.
How to Divide Blueberry Bushes Step by Step
Ready to get your hands dirty?
Here’s the process for dividing blueberry bushes properly.
1. Water the Bush the Day Before
Give the bush a deep soak the day before you plan to divide it.
Moist soil holds together better and puts less stress on the roots when you lift them.
2. Dig Around the Root Zone
Use a sharp spade to dig a wide circle around the bush, starting about 15 inches from the base.
Work the spade underneath and lift the whole root ball gently.
3. Separate the Sections
Lay the root ball on a tarp and look for natural splits in the crown.
Use a clean, sharp knife, pruners, or even two garden forks back-to-back to pry the sections apart.
Each division should have at least two or three healthy stems and a solid chunk of roots.
4. Replant Immediately
Plant each division at the same depth it was growing before.
Blueberries need acidic soil with a pH between 4.5 and 5.5, so amend your planting holes with peat moss or pine bark if needed.
5. Water Deeply After Planting
Soak each new bush thoroughly to settle the soil around the roots and remove air pockets.
Keep the soil consistently moist for the first few weeks.
Aftercare for Divided Blueberry Bushes
The work doesn’t stop once you’ve finished dividing blueberry bushes.
1. Mulch Heavily
Apply a 3 to 4 inch layer of pine bark, wood chips, or straw around each plant.
Mulch keeps the shallow roots cool and moist, which is critical after dividing blueberry bushes.
2. Skip Fertilizer Until They Establish
Don’t feed newly divided bushes right away.
Wait until you see new growth, then use a fertilizer made for acid-loving plants.
3. Prune Off Weak Growth
Remove any spindly or damaged stems so the plant puts energy into root development.
Give your divided blueberry bushes a full season before expecting a real harvest.
So, Can You Divide Blueberry Bushes?
Yes, you can divide blueberry bushes, and it’s a smart way to get more plants for free while rejuvenating an older bush.
Just do it in late winter or early spring, keep the roots moist, and plant each division in acidic soil with plenty of mulch.
With a little patience, the sections you separated will grow into productive bushes of their own.
So grab your spade, pick a dormant day, and try dividing blueberry bushes this season.
