Growing Blackberries In Your Backyard: The perfect addition to your food forest. 

Imagine stepping into your backyard and plucking plump, juicy blackberries right off the vine. The sweetness bursts in your mouth, a taste of summer you grew yourself. 

Sounds amazing, right? 

Well, get ready to turn that dream into reality! Growing blackberries is easier than you think, and we’re here to guide you through it. Whether you’re a seasoned gardener or just starting out, you’ll be surprised at how simple it can be to cultivate your own blackberry patch. So, grab your gardening gloves, and let’s get started on this delicious adventure!

Understanding Blackberry Varieties

The first step to growing blackberries is understanding the different varieties.  There are 3 main varieties you’re likely to find in your local garden center: erect blackberries, trailing blackberries, and semi-erect blackberries. Each type requires specific care, from the blackberry trellis needed by trailing types to the blackberry pruning techniques essential for erect and semi-erect varieties. The success of your blackberry harvest lies in selecting a variety that matches your garden’s particular growing conditions. 

Erect blackberries stand tall without support, while trailing blackberries drape gracefully and need a structure to cling onto. Semi-erect varieties blend these characteristics, resulting in a middle-ground option. 

Choosing wisely can prevent issues related to blackberry disease and enhance your capability to harvest blackberries at the peak of ripeness, maximizing the health benefits of their rich ellagic acid and antioxidant content.

The Life Cycle of a Blackberry Plant

Believe it or not, blackberries actually have a unique life cycle. The roots of these berry plants are perennial, meaning they come back year after year. This characteristic ensures a stable foundation from which the rest of the plant can flourish. On the other hand, the tops of blackberry plants are biennial in nature. They spring to life and grow vegetatively for a year, then bear fruit the following season before their cycle concludes and they die off.

This unique duality within the plant’s structure requires thoughtful cultivation practices. It allows you to harvest blackberries annually, crediting to the enduring nature of the roots and the cyclic regeneration of the tops. 

Understanding this cycle is fundamental. It guides the timing of planting, pruning, and harvesting, ensuring that your efforts yield the abundant, delicious blackberries you desire.

When to Plant Blackberries

Blackberries should be planted in late spring when the soil is sufficiently warm. Blackberries are sensitive to frost so timing is critical to ensure your blackberry varieties, whether erect, trailing, or semi-erect, get the best start. These plants crave the warmth to foster strong root development, which is essential for robust growth and a bountiful harvest. 

How to Plant Blackberries

Now that you’re ready to create your blackberry haven, the first step is choosing the perfect spot in your yard. Blackberries are sun-lovers, so find a sunny spot that gets at least 6-8 hours of direct sunlight each day. They also appreciate some space to spread out, so make sure they have enough room to grow (ideally 5 to 6 feet apart). Finally, make sure the soil is well draining because blackberries, like blueberries, hate to have “wet feet.”

After planting, water the blackberries thoroughly. It’s a crucial step to settle them into their new environment. A layer of mulch will be beneficial, retaining moisture and suppressing weeds. 

Blackberries can be a bit rambunctious, so a sturdy trellis or support system will keep them in check and make harvesting a breeze. With the right location and support, your blackberries will thrive and reward you with an abundance of delicious fruit. Let’s get those berry vines planted!

The Importance of Proper Pruning

Pruning had proven crucial in cultivating bountiful blackberries. For erect blackberries, summer cutting back encourages denser growth. Trailing types demanded a trellis, a method shown to enhance yields significantly. Semi-erect varieties thrived with both summer and winter trims, adapting well to the structure of a Double T Trellis. 

Pruning not only prevents a jungle of blackberry canes but also stimulates healthier, more productive plants. By removing old floricanes (the canes the berries grew on) after they bear fruit, makes room for fresh primocanes (new canes that will produce berries next year).

This practice ensures ample sunlight and air circulation, reducing the risk of disease. Regardless of the variety, mastering pruning methods will prove to be a game changer in yoru backyard garden.

Trellising Systems for Blackberries

Choosing the right trellising system for blackberries is essential for promoting healthy growth and ease of harvest. For trailing blackberries, we recommend a two-wire system. This involves setting up wires at five to six feet off the ground, upon which you train the blackberry canes. 

Erect blackberries, known for their stiff, shorter canes, thrive without such support but benefit significantly from proper pruning to maintain structure and productivity. Semi-erect blackberries find their match in a Double T Trellis. You’ll erect posts with cross arms, creating an effective support for these varieties to flourish. 

Each system is designed to maximize sun exposure and air circulation, both critical factors in reducing disease and enhancing your berry yield.

Summer Pruning

Summer pruning is important if you want to have thriving erect and semi-erect blackberries. Believe it or not, cutting back these vigorous plants could, surprisingly, yield more fruit. Erect blackberries stiffen with pruning, shooting up new canes to manageable heights. Semi-erect varieties, once pruned, will branch out, filling your trellis system with promising buds. 

This technique involves eliminating the weaker canes and allowing the stronger ones the energy they need to flourish.

Winter Pruning

Once the chill sets in, focusing on your blackberry trellis becomes essential. Unlike the careful maintenance of summer pruning, this winter ritual involves a more decisive action. You will remove the canes that bore fruit last season, as these will not produce again. This practice encourages the plant to channel energy into new growth, boosting your chances for a bountiful harvest come summer.

Managing Pests and Diseases 

Managing diseases and pests forms a crucial part of blackberry cultivation, and the battle against these adversaries must be strategic. Blackberry disease can ravage a crop, leading to significant losses. Fungal infections, such as rust, often strike, leaving plants weakened. 

To combat these common enemies, make sure your blackberries get ample airflow by spacing them 5 to 6 feet apart and pruning regularly. 

When it comes to pests, vigilance is key. High-tensile wire systems not only support your plants but can also deter some pests by keeping the blackberries elevated.

Tomato cages have a lesser-known use in managing blackberry pests. By creating barriers, they can protect young shoots from being devoured. Regularly inspect your plants for signs of infestation. Early intervention can prevent pests from spreading throughout your blackberry patch. 

If you’re having issues with birds or squirrels eating your berries, we recommend using insect netting to cover the plant.  

Harvesting Blackberries

For the most flavorful experience, pick your blackberries at their peak of ripeness. You will notice they have fully matured when the fruit transforms into a deep, uniform black. Attempting to pick them before this stage might lead to sourness. 

Gently tug at the berry; if ready, it will detach with ease, signaling it’s time for harvest. Practice patience though, as blackberries do not ripen all at once. Check your plants every couple of days during the season. 

Storing Your Harvest

Once you have harvested blackberries at their peak of ripeness, storing them properly will be your next challenge. First, inspect the berries carefully and remove any that are damaged or moldy. This step ensures that one bad berry does not spoil the bunch. Gently place the blackberries in a shallow container, avoiding overcrowding, which can cause them to crush under their own weight. For optimal freshness, line the container with a paper towel to absorb any excess moisture. Blackberries should be kept refrigerated, where they can last for up to a week if stored correctly.

For longer preservation, consider freezing the blackberries. Spread them out on a baking sheet in a single layer, freeze until solid, then transfer them into a freezer bag. This method prevents the berries from sticking together, granting you the flexibility to use the exact amount you need without thawing the entire batch. Frozen blackberries can be kept for several months, making them a delightful addition to smoothies or recipes at any time.

Priming for Double Cropping

Blackberry enthusiasts often seek advanced cultivation techniques, aiming for higher yields and extended harvests. Priming for double cropping stands out as a noteworthy strategy, particularly with primocane fruiting varieties such as the Prime Ark Freedom. This method enables gardeners to harvest twice in one year from the same plants. It could seem complex at first, but understanding the fundamentals simplifies the process.

Initially, you’ll focus on your blackberry’s life cycle. After the first year’s growth, canes called floricanes bear fruit in late spring or early summer. Post harvest, these canes will die, but the plant remains productive. New canes, known as primocanes, emerge and mature in summer. They bear fruit in late summer to early autumn, offering a second crop. Contrary to concerns, double cropping does not diminish the vigor of primocanes. Instead, when canes are cut down after the late harvest, the subsequent year’s primocane crop often comes in even more abundantly.
