Blackberry bushes are a perfect addition to any garden. With some basic knowledge and care, these delicious berries can easily be grown at home. Keep reading to learn all about growing blackberries!
What are Blackberries?
Blackberries are a type of berry that belong to the genus Rubus in the rose family. There are three types of blackberry bushes: erect blackberries, trailing blackberries, and thornless blackberries.
All types grow best in full sun and well-drained soil with a pH of 6.0-6.5. Here are more details about each type of blackberry:
1. Erect blackberries are semi-erect plants that have stiff canes and thorns along its stem. These plants produce sweet, medium-sized berries from mid-summer to late autumn.
2. Trailing blackberries are vigorous climbing plants with long, thin canes. They produce large, sweet berries from early to mid-summer.
3. Thornless blackberries are more compact and have shorter canes than other types of blackberry bush. They produce larger, sweeter fruits from early summer to late autumn.
When to Plant Blackberries
It is best to plant blackberry bushes in the early spring as soon as the soil can be worked. It is important to choose an area with well-drained soil, full sun, and protection from strong winds.
Where to Plant Blackberries
Blackberry bushes can be planted in the ground or in containers. If planting in the ground, make sure to space plants 2–3 feet apart and place rows 6–10 feet apart. For container planting, use a large pot with drainage holes and fill it with a quality potting mix.
How to Plant Blackberries
When planting blackberries in the ground, dig a hole twice as wide and deep as the root ball of your bush. Place the bush in the hole so that its crown (the point at which the roots meet the stems) is level with the soil surface.
Backfill and water. For container planting, make sure the pot is big enough to allow for root growth and fill it halfway with potting mix. Place your bush in the pot and backfill with more potting mix, making sure that there are no air pockets. Water thoroughly after planting.
Growing Blackberries in Containers
Growing blackberries in containers is a great way to enjoy these delicious berries in small spaces. Use a large container with drainage holes and fill it halfway with a quality potting mix.
Place the blackberry bush in the pot, making sure that its crown (the point at which the roots meet the stems) is level with the soil surface. Backfill with more potting mix and water thoroughly.
Make sure to place the container in a sunny spot, as blackberries need at least 6 hours of direct sunlight each day. For best results, make sure to fertilize your blackberry bush every few weeks with a balanced fertilizer.
Also keep an eye out for pests and diseases, as these can be problematic in containers. With proper care and maintenance, your blackberry bush should produce sweet, delicious berries in no time.
Growing Thornless Blackberries
Thornless blackberries are a great option for those who don’t want to worry about getting stuck by thorns while harvesting.
These plants are more compact and have shorter canes than other types of blackberry bush, making them ideal for container planting or growing in small spaces. Plant thornless blackberries in early spring as soon as the soil can be worked.
Choose an area with well-drained soil, full sun, and protection from strong winds. Make sure to space plants 2–3 feet apart and place rows 6–10 feet apart if planting in the ground.
For container planting, use a large pot with drainage holes and fill it with a quality potting mix. Place your bush in the pot so that its crown (the point at which the roots meet the stems) is level with the soil surface.
Backfill with more potting mix and water thoroughly after planting. Make sure to fertilize your thornless blackberry bush every few weeks with a balanced fertilizer.
How to Care for Blackberries
Once planted, blackberry bushes need regular watering and fertilizing. Water deeply and regularly during the growing season to keep the soil evenly moist.
Fertilize once a month with a balanced fertilizer such as 10-10-10 or 8-8-8. Pruning is also important for promoting healthy growth and abundant fruit set. Prune away dead or diseased canes, as well as any canes that are more than two years old.
How to Harvest and Store Blackberries
Blackberries are ready to harvest when they turn a deep purple color and are soft to the touch. Pick the berries on dry days when they are not wet from dew or rain.
Gently twist the berries off the stem and place them in a shallow container. Refrigerate ripe berries immediately to keep them fresh for up to a week.
Pests and Diseases
Blackberries are susceptible to various pests and diseases, including aphids, cane borers, rust, black spot, mildew, and verticillium wilt. Inspect your plants regularly, and if you notice any signs of damage or disease, take action immediately to mitigate the problem.
Frequently Asked Questions
Here are some frequently asked questions you may have about growing blackberries in your garden.
What is the secret to growing blackberries?
There is no secret to growing blackberries. By following the below tips, you should be able to grow healthy and delicious blackberries for your family and friends to enjoy!
- Selecting the Perfect Location: When it comes to growing blackberries, selecting the right location is crucial. These sun-loving plants thrive in full sunlight, so choose a spot in your garden that receives at least six to eight hours of direct sunlight each day. Additionally, ensure the soil is well-draining and rich in organic matter to provide the blackberry plants with optimal growing conditions.

Start by digging a hole that’s wide and deep enough to accommodate the plant’s root system comfortably. Gently spread out the roots and position the plant at the same depth it was grown in the nursery. Fill the hole with soil, firm it gently, and water thoroughly.
- Pruning and Training: Pruning and training blackberry plants are essential for optimal growth and fruit production. Begin by pruning the canes during the dormant season to remove weak or damaged ones. For erect varieties, prune them back to about 4-5 feet in height, while trailing varieties should be pruned to about 6-7 feet in length. Consider using a trellis or a support system to train the canes, keeping them upright and making it easier to harvest the fruits.
- Watering and Fertilizing: To ensure healthy growth, blackberry plants require regular watering. During the growing season, provide them with about an inch of water per week, either through rainfall or irrigation. Apply water at the base of the plants to prevent wetting the foliage, which can lead to diseases. Additionally, fertilize the plants in early spring with a balanced fertilizer to provide essential nutrients for vigorous growth and abundant fruit production.
- Pest and Disease Management: Growing blackberries comes with its fair share of challenges, including pests and diseases. Regularly inspect your plants, and if you spot any signs of infestation, take appropriate measures to control them, such as using insecticidal soaps or organic pest control methods. Disease prevention is equally important, so ensure good air circulation, avoid over-watering, and promptly remove any diseased plant material.
- Harvesting and Enjoying the Fruits of Your Labor: Once your blackberry plants start producing fruits, it’s time to reap the rewards of your hard work. Harvest ripe berries when they turn shiny black and easily detach from the plant with a gentle tug. Depending on the variety, harvesting can take place over several weeks. Enjoy the juicy, sweet blackberries fresh, or incorporate them into your favorite recipes to savor their unique flavor and health benefits.
As you can see, the secret to growing blackberries is caring for them using the above steps to ensure a successful harvest!
How long does it take for a blackberry tree to bear fruit?
Before we discuss the timeline for blackberry fruiting, it’s essential to understand the growth cycle of these plants. Blackberries are perennial plants that undergo a biennial cycle.
The first year is dedicated to vegetative growth, while the second year focuses on fruiting. This means that when you initially plant a blackberry shrub, it will take some time for it to mature and start bearing fruit.
- First Year: Establishment and Growth During the first year of growing blackberries, the focus is on establishing a healthy root system and robust vegetative growth. In this stage, the plant develops canes (stems) but does not produce any fruit.
- Second Year: Fruit Production Begins In the second year, your patience and efforts will be rewarded as the blackberry plant starts to bear fruit. Generally, most blackberry varieties begin fruiting in their second year, though the exact timing may vary slightly depending on factors such as the specific variety, growing conditions, and climate.
By the second year, the blackberry canes have matured and developed the necessary structures to support fruit production. Flower buds form on the canes during the early spring.
As the weather warms up, these buds blossom into beautiful white or pink flowers, which are then pollinated by bees or other insects.
After pollination, the flowers give way to small green berries that gradually grow and ripen. The ripening process typically takes several weeks, and you will notice the berries transitioning from green to a deep, luscious black color.
- Subsequent Years: Increased Productivity As your blackberry plant continues to mature, it will become more productive with each passing year. In the third and subsequent years, you can expect even larger yields of juicy blackberries.
While the general timeline mentioned above provides a framework for blackberry fruiting, it’s important to note that individual variations may occur based on growing conditions and specific cultivars.

They can be grown in traditional garden beds, raised beds, or containers, allowing you to adapt to the available space in your garden. Additionally, blackberries can be trained on trellises or fences, which not only optimizes space but also makes harvesting easier.
- Abundant Harvests and Culinary Delights: Perhaps the most rewarding aspect of growing blackberries is the opportunity to indulge in their delectable fruits. When the time is right, you’ll be rewarded with plump, juicy blackberries bursting with flavor. These versatile berries can be enjoyed fresh off the vine, used in jams, jellies, pies, smoothies, or incorporated into a variety of recipes.
Growing blackberries is an enjoyable and relatively easy endeavor. Their hardiness, adaptability, low maintenance requirements, and generous productivity make them an excellent choice for both beginner and experienced gardeners.
Do all blackberries need a trellis?
When it comes to growing blackberries, whether or not you need a trellis depends on the type of blackberry you are cultivating and your desired growth method.
Blackberries can be categorized into two main types: trailing blackberries and erect blackberries.
Trailing blackberries, as the name suggests, have long, flexible canes that tend to grow in a sprawling manner. These varieties generally benefit from being trained on a trellis or some form of support system.
By providing a trellis, you can help guide the canes to grow vertically, which not only saves space but also improves air circulation and sunlight exposure, leading to healthier plants and better fruit production.
Trellising trailing blackberries also facilitates easier maintenance, such as pruning and harvesting.
On the other hand, erect blackberries have sturdier canes that tend to grow upright without much need for support. These varieties often have a more compact growth habit and can stand upright without the assistance of a trellis.
Even though erect blackberries can grow without a trellis, providing some support can still be beneficial. A trellis or stakes can help keep the canes organized, prevent them from leaning over, and protect them from wind damage.
Trellising erect blackberries can make it easier to manage the plants and access the berries during harvesting.
While not all blackberries necessarily require a trellis, it is generally recommended to provide some form of support for optimal growth and fruit production.
Growing blackberries at home can be a rewarding experience. With some basic knowledge and care, you can enjoy an abundance of sweet, juicy berries for years to come!
