Blackberries should be planted about 3 to 5 feet apart within a row, with 8 to 10 feet between rows if you’re growing them in a traditional hedgerow system.
But how far apart you plant blackberries really depends on the variety you choose and the growing method you use.
If you’ve been wondering how far apart to plant blackberries for a healthy, productive patch, you’re in the right place.
In this post, we’ll break down the ideal blackberry plant spacing, why it matters, and how to get it right the first time.
Let’s dig in.
How Far Apart Do You Plant Blackberries?
The short answer is that blackberry plant spacing usually falls somewhere between 3 and 5 feet within a row.
But there’s more to it than just picking a number.
Here’s what influences how far apart you plant blackberries:
1. The Type of Blackberry You’re Growing
Erect blackberries are the most common type home gardeners grow, and they’re typically planted 3 to 4 feet apart.
Semi-erect and trailing varieties spread wider, so you’ll want to space them 5 to 6 feet apart to give them room to breathe.
Knowing your variety is the first step in figuring out how far apart to plant blackberries.
2. The Growing System You Choose
If you’re using a hedgerow system, blackberries are planted 3 to 5 feet apart in a continuous row.
If you’re growing them individually on a trellis or in a hill system, you can space them 4 to 6 feet apart.
Either way, the goal is to give each plant enough room for airflow and sunlight.
3. The Mature Size of the Plant
Blackberry plants can spread 4 to 6 feet wide once they’re mature.
If you plant them too close, their canes will tangle, which makes harvesting a nightmare and invites disease.
So when you’re deciding how far apart to plant blackberries, always think about the size they’ll be in two or three years, not the size they are now.
Why Blackberry Plant Spacing Matters
Getting the spacing right when you plant blackberries isn’t just about looks.
It affects their health, yield, and how easy they are to manage.
1. Better Airflow Means Fewer Diseases
Blackberries are prone to fungal issues like anthracnose and botrytis.
When you plant blackberries too close together, air can’t move through the patch, and moisture lingers on the leaves.
Proper blackberry plant spacing keeps that air moving and keeps disease at bay.
2. More Sunlight Equals Sweeter Berries
Blackberries need full sun to produce the biggest, sweetest fruit.
If plants are crowded, the ones in the back get shaded out and produce less.
Spacing them correctly means every cane gets its share of sunlight.
3. Easier Harvesting and Pruning
Trust me, you’ll thank yourself at harvest time.
When you plant blackberries with enough space between them, you can walk between the rows and reach every berry without getting scratched up.
Pruning is also way easier when you can actually see what you’re doing.
4. Stronger Root Systems
Blackberries have extensive root systems that need room to spread.
When plants are too close, they compete for water and nutrients.
Good blackberry plant spacing gives each plant its own little territory to thrive in.
How to Space Blackberries in Different Settings
The ideal spacing for blackberries changes a bit depending on where you’re planting them.
1. In a Home Garden Row
Plant blackberries 3 to 5 feet apart in the row, with 8 to 10 feet between rows.
This gives you room to walk and work between them.
2. Along a Fence or Trellis
If you’re planting blackberries along a fence, space them 4 to 6 feet apart.
This allows the canes to fan out and get good sun exposure on both sides.
3. In Containers
Yes, you can grow blackberries in pots, but you’ll need one plant per large container.
A 20-gallon pot is about right for a single blackberry plant.
4. As a Hedgerow
For a hedgerow, plant blackberries 3 feet apart in a row and let them fill in.
Just keep the row width to about 2 feet so you can still manage the canes.
Common Mistakes When You Plant Blackberries
Even experienced gardeners mess this up sometimes.
Planting blackberries too close is the number one mistake.
It seems like a good idea at first because you want a full patch fast.
But within a year or two, you’ll regret it when the canes are a tangled mess.
Another mistake is not accounting for the spread of trailing varieties.
They can easily sprawl 6 feet or more, so give them extra room.
And don’t forget to leave space between rows, not just between plants.
You need room to walk, prune, and harvest.
So, How Far Apart Do You Plant Blackberries?
Blackberries should be planted 3 to 5 feet apart within a row and 8 to 10 feet apart between rows.
But the exact blackberry plant spacing depends on the variety, the growing system, and how much room you have.
The key is to give each plant enough space for airflow, sunlight, and root growth.
Get the spacing right when you plant blackberries, and you’ll be rewarded with healthier plants and bigger harvests for years to come.
