To grow triple crown blackberries, you need a sunny spot, well-drained soil, and a sturdy trellis to support these vigorous semi-erect canes.
Triple Crown blackberries are a favorite among home gardeners because they produce big, sweet berries with a fraction of the work compared to other varieties.
Unlike trailing types that demand constant tying and training, triple crown blackberries grow upright on their own, which makes them much easier to manage.
They’re also thornless, super productive, and disease-resistant, so you get all the reward without the scratches.
If you’ve been wondering how to grow triple crown blackberries in your own backyard, you’re in the right place.
In this post, we’ll walk through everything from picking the right spot to pruning at the right time so your triple crown blackberries thrive season after season.
Let’s dig in.
Why Grow Triple Crown Blackberries
Triple Crown blackberries are worth growing because they deliver huge harvests of sweet, juicy fruit with very little fuss.
Here’s what makes them such a standout choice:
1. Thornless and Easy to Handle
One of the biggest reasons gardeners grow triple crown blackberries is that the canes have no thorns.
That means you can reach in and pick berries without gloves or worry.
Pruning and training are far more pleasant too.
2. Heavy Yields of Large Berries
A mature triple crown blackberry plant can produce up to 30 pounds of fruit in a single season.
The berries are long, firm, and sweet with a mild tang that’s perfect for fresh eating, pies, and jams.
3. Semi-Erect Growth Habit
Triple crown blackberries grow semi-erect, meaning the canes stand up on their own before arching over.
This makes them easier to trellis and keeps your patch tidy compared to sprawling trailing varieties.
4. Disease Resistance
These plants show strong resistance to common blackberry diseases like rust and anthracnose.
That resilience means fewer sprays and healthier canes year after year.
How to Grow Triple Crown Blackberries Step by Step
Growing triple crown blackberries comes down to giving them the right site, soil, and support from day one.
1. Choose Full Sun
Plant triple crown blackberries in a spot that gets at least six to eight hours of direct sunlight daily.
More sun means sweeter berries and stronger canes.
2. Prep Well-Drained Soil
Triple crown blackberries hate soggy roots, so make sure your soil drains well.
Mix in compost and aim for a pH between 5.5 and 6.5.
If your ground stays wet, plant on a raised bed or mound.
3. Set Up a Trellis
Even though triple crown blackberries are semi-erect, they still need support once fruit sets in.
A simple two-wire trellis with posts about six feet apart works great.
4. Plant at the Right Depth
Set your triple crown blackberries so the crown sits just below the soil line.
Space plants three to four feet apart in rows eight to ten feet apart.
5. Water Consistently
Give your triple crown blackberries about an inch of water per week.
Drip irrigation keeps foliage dry and helps prevent disease.
6. Mulch and Feed
Spread two to three inches of mulch to hold moisture and block weeds.
Feed triple crown blackberries in early spring with a balanced fertilizer.
Pruning and Caring for Triple Crown Blackberries
Pruning is the secret to keeping triple crown blackberries productive year after year.
1. Understand the Two-Year Cycle
Triple crown blackberries produce fruit on second-year canes called floricanes.
After those canes fruit, they die and should be removed.
2. Prune in Late Winter
Cut back dead floricanes and tip the new primocanes to encourage branching.
This keeps your triple crown blackberries from turning into a tangled mess.
3. Remove Spent Canes After Harvest
Once you’ve picked your berries, cut the fruited canes to the ground.
This frees up energy for next year’s growth.
4. Watch for Pests and Disease
Triple crown blackberries are tough, but keep an eye out for aphids and spider mites.
Good airflow and proper spacing do most of the work for you.
5. Harvest When Berries Turn Deep Black
Pick triple crown blackberries when they’re fully black and pull off easily.
They don’t ripen after picking, so patience pays off here.
So, How Do You Grow Triple Crown Blackberries?
You grow triple crown blackberries by planting them in full sun, giving them well-drained soil, and training the canes on a sturdy trellis.
These thornless, semi-erect plants reward you with massive harvests and easy care once they’re established.
Water consistently, mulch well, and prune on the right schedule so your triple crown blackberries keep producing for years.
Get the basics right and you’ll be picking bowls of sweet berries before you know it.
