The best time to plant blackberries is in early spring or late winter while the plants are still dormant.
Planting at this time gives the roots a chance to settle in before the heat of summer arrives.
If you’re wondering how and when to plant blackberries, the short answer is simple: get them in the ground while they’re sleeping, not while they’re growing.
Blackberries are surprisingly forgiving, but timing really does matter if you want a strong harvest.
In this post, we’ll walk through when to plant blackberries, how to plant them properly, and a few tips to keep them thriving.
Let’s dig in.
When to Plant Blackberries
You should plant blackberries during their dormant season, and here’s why that timing works so well:
1. Early Spring Is the Sweet Spot
Early spring is the ideal window for how and when to plant blackberries in most regions.
The soil has warmed up enough to work with, but the plants haven’t started pushing out new growth yet.
This gives the roots time to establish themselves before they have to support leaves and fruit.
If you plant too late, the plant spends energy on top growth while its roots are still struggling to settle in.
2. Late Winter Works in Mild Climates
If you live in a warmer climate, late winter is actually a great time to plant blackberries.
The ground rarely freezes in these areas, so the roots can start growing right away.
Just make sure the soil isn’t waterlogged, because soggy conditions can rot the roots before they get going.
3. Avoid Planting in Summer or Peak Heat
Knowing when to plant blackberries also means knowing when not to.
Avoid planting in the middle of summer when temperatures are high and the plant is under stress.
Heat pulls moisture from the leaves faster than the roots can replace it, which can kill a young blackberry plant quickly.
4. Fall Planting Is Possible but Riskier
Some growers plant blackberries in early fall, but this comes with risk.
If a sudden freeze hits before the roots are established, your plants may not survive the winter.
If you do plant in fall, do it at least six weeks before your first expected frost.
How to Plant Blackberries Step by Step
Now that you know when to plant blackberries, let’s talk about how to plant them so they actually take off.
1. Pick the Right Spot
Blackberries need full sun, at least six to eight hours a day.
They also need good drainage because standing water is a death sentence for their roots.
If your soil holds water, plant on a raised bed or mound to keep things dry.
2. Prepare the Soil
Before you plant blackberries, work the soil about a foot deep.
Mix in compost or aged manure to give the roots something nutritious to grow into.
A soil pH between 5.5 and 6.5 is ideal for how and when to plant blackberries successfully.
3. Space Them Properly
Give each plant about three to five feet of space in a row.
If you’re planting multiple rows, keep them six to eight feet apart.
Good airflow between plants helps prevent disease later on.
4. Dig and Plant
Dig a hole wide enough to fit the roots without bending them.
Set the plant so the crown sits right at soil level, not buried and not sticking out.
Backfill with soil, press it down gently, and water thoroughly to settle everything in.
5. Water and Mulch
After you plant blackberries, give them a deep watering right away.
Then spread a layer of mulch around the base to hold moisture and keep weeds down.
Just keep the mulch a couple of inches away from the stems to avoid rot.
Tips for Growing Blackberries After Planting
Planting blackberries is only half the battle, and a few habits will keep them healthy.
1. Water Consistently
Blackberries need about an inch of water per week, especially during fruiting.
2. Trellis Them
A simple trellis keeps canes off the ground and makes picking easier.
3. Prune Old Canes
Cut back canes that fruited last year so new growth has room to thrive.
So, How and When to Plant Blackberries?
You plant blackberries in early spring or late winter while they’re dormant, and you plant them in full sun with well-drained soil.
Timing gives the roots a head start, and proper planting gives them a home they can thrive in.
Get both right, and you’ll be picking fresh blackberries before you know it.
