Choosing the Right Varieties


When it comes to planting blackberries, choosing the right variety is crucial for a successful harvest. There are several types of blackberries to choose from, each with its own unique characteristics. Here are the three main categories of blackberries to consider:


Erect Blackberries


Erect blackberries, also known as upright blackberries, grow in a bush-like shape and are generally easier to maintain than trailing varieties. They are also less susceptible to disease and can be grown in smaller spaces. Some popular erect blackberry varieties include:

  • Apache‘: A thorny cultivar with large, sweet berries
  • ‘Navaho’: A thornless cultivar with high yields and firm berries
  • Triple Crown‘: A semi-erect thornless cultivar with large, flavorful berries


Trailing Blackberries


Trailing blackberries, also known as trailing varieties, grow on long canes that trail along the ground or require trellising. They tend to produce larger berries than erect varieties, but are also more prone to disease. Some popular trailing blackberry varieties include:

  • Chester‘: A thornless cultivar with large, juicy berries
  • ‘Marion’: A thorny cultivar with rich, complex flavor
  • ‘Boysen’: A thorny cultivar with large, sweet-tart berries


Thornless Varieties


Thornless varieties of blackberries are ideal for those who want to avoid the painful thorns that come with traditional blackberry bushes. They are available in both erect and trailing varieties and tend to be easier to harvest. Some popular thornless blackberry varieties include:

  • Arapaho‘: An erect thornless cultivar with large, sweet berries
  • Natchez‘: A trailing thornless cultivar with high yields and firm berries
  • Ouachita‘: A semi-erect thornless cultivar with large, juicy berries


When choosing a blackberry variety, consider factors such as your climate, available space, and personal taste preferences. With the right variety, you can enjoy a bountiful harvest of delicious blackberries year after year.

Preparing the Planting Site


When it comes to planting blackberries, preparing the planting site is crucial. Proper preparation will ensure that your blackberry plants grow healthy and produce a bountiful harvest. Here are some key factors to consider when preparing your planting site.


Soil Requirements


Blackberries thrive in well-draining soil that is rich in organic matter. Before planting, make sure to test your soil’s pH level.


You can easily test the pH of your soil with this inexpensive soil pH testing kit. Blackberries prefer a pH range of 5.5 to 7.0. If your soil is too acidic, you can add lime to raise the pH level. If it’s too alkaline, you can add sulfur to lower it.


Sunlight and Location


Blackberries require full sun to produce the best fruit. Make sure to choose a location that receives at least six hours of direct sunlight each day. Additionally, blackberries prefer to be planted in USDA hardiness zones 5-8.


Good Drainage and Soil pH


Good drainage is essential for blackberry plants. If the soil doesn’t drain well, the plants can become waterlogged and develop root rot.


To improve drainage, you can add compost to the soil. This will also help increase the soil’s organic matter content, which is beneficial for blackberry growth.


In summary, when preparing the planting site for your blackberry plants, make sure to consider the soil requirements, sunlight and location, and good drainage. By taking these factors into account, you can ensure that your blackberry plants grow healthy and produce a bountiful harvest.


Planting and Spacing


Planting Techniques


Blackberries are easy to plant and care for, making them a great addition to any garden. When planting blackberries, it is important to choose a sunny location with well-draining soil. Before planting, ensure that the soil is free of weeds and other debris.


To plant blackberries, dig a hole that is twice as wide and deep as the root ball of the plant. Place the plant in the hole and backfill with soil, making sure that the plant is level with the ground.


Water the plant well and add a layer of mulch around the base of the plant to help retain moisture and suppress weeds.

Spacing for Growth


Proper spacing is essential for the growth and health of blackberry plants. The spacing requirements will vary depending on the type of blackberry plant you are growing.


For erect blackberries, which have thorns and require support, space the plants 3-5 feet apart in rows that are 8-10 feet apart. This will allow the plants to grow and spread out, while still providing enough room for support structures.


Trailing thornless blackberries, on the other hand, can be spaced 5-6 feet apart in rows that are 10-12 feet apart. These plants do not require support, but they will spread out and fill in the space over time.


Erect thornless blackberries should be spaced 3-4 feet apart in rows that are 8-10 feet apart. These plants do not have thorns and require support, but they are more compact than their thorny counterparts.


Finally, erect thorny blackberries should be spaced 3-5 feet apart in rows that are 8-10 feet apart. These plants have thorns and require support, but they are more vigorous than the thornless varieties.


By following these spacing guidelines, you can ensure that your blackberry plants have enough room to grow and thrive.


Caring for Blackberry Plants


Blackberries are easy to grow and maintain, but they do require some care to thrive. Here are some tips on how to care for your blackberry plants.


Watering and Moisture


Blackberry plants need consistent moisture, especially during the growing season. Make sure to water them deeply at least once a week, and more often during hot, dry weather.


Avoid getting water on the leaves, as this can encourage disease. Consider installing a drip irrigation system to ensure consistent moisture.


Mulching and Fertilizing


Mulching is important for blackberry plants because it helps retain moisture and suppress weeds. Apply a layer of organic mulch, such as straw or wood chips, around the base of the plants.


Fertilize your blackberry plants in early spring with a balanced fertilizer, and again in late spring with a fertilizer high in nitrogen.


Pruning and Training


Pruning is essential for blackberry plants to increase yield and maintain plant health. Prune your blackberry plants in late winter or early spring before new growth appears.


Remove any dead or damaged canes, as well as any canes that are more than two years old. Train the remaining canes onto a trellis or support system to keep them off the ground and make harvesting easier.


Protecting from Pests and Diseases


When it comes to growing blackberries, pests and diseases can be a major concern. But with proper care and attention, you can prevent and manage these issues to keep your plants healthy and productive.


Common Pests


Birds are a common pest that can damage blackberry plants and eat the fruit. To protect your plants, you can cover them with netting or use scare tactics like reflective tape or fake predators.


Another common pest is the spotted-wing drosophila, which lays eggs in ripening fruit. To prevent infestations, harvest fruit as soon as it is ripe and dispose of any fallen fruit.


Disease Prevention


Blackberries can be susceptible to diseases like anthracnose, crown gall, and orange rust. To prevent these diseases, it is important to maintain good plant health by providing proper nutrition and watering.


Avoid overhead watering, which can promote disease spread, and prune plants to improve air circulation. If you notice signs of disease, like wilting or discoloration, remove affected plant parts and dispose of them properly.


In addition to these preventative measures, it is also a good idea to practice crop rotation and avoid planting blackberries in the same location year after year. This can help prevent the buildup of soil-borne diseases and pests.


Harvesting and Storage


When to Harvest


Knowing when to harvest your homegrown blackberries is crucial to getting the best taste and texture. Blackberries are ripe when they are plump, shiny, and have a deep color. If the berries are still hard or have a dull color, they are not yet ripe.


It’s important to harvest blackberries when they are fully ripe because they will not continue to ripen after being picked. If you wait too long, the berries will become soft and mushy, making them difficult to handle and less enjoyable to eat.


How to Store Blackberries


Once you have harvested your blackberries, it’s important to store them properly to ensure they stay fresh for as long as possible. The best way to store blackberries is to keep them in the refrigerator.


Place the berries in a shallow container and cover them with plastic wrap. This will help prevent moisture from getting in and causing the berries to spoil.


If you have a large amount of blackberries, you can also freeze them for later use. To freeze blackberries, first wash them and pat them dry.


Spread them out on a baking sheet and place them in the freezer until they are frozen solid. Once frozen, transfer them to a freezer-safe container or bag and store them in the freezer for up to six months.


When you’re ready to use your frozen blackberries, simply thaw them in the refrigerator overnight or at room temperature for a few hours. They can be used in recipes just like fresh blackberries.


Propagation and Yearly Cycle


Propagating Blackberries


Blackberries can be propagated through cuttings, division, or seeds. The easiest and most common method is through cuttings.


Cut a 6-inch long stem from a healthy blackberry plant during the dormant season (late fall to early spring), and plant it in well-draining soil. Keep the soil moist and in a warm, sunny location. In a few weeks, roots will start to grow, and a new plant will emerge.


Division is another method of propagation, but it requires an established plant. Dig up the plant during the dormant season and carefully divide it into smaller sections, each with its own roots and stems. Replant the sections in well-draining soil and keep them moist until new growth appears.


Growing blackberries from seeds is possible, but it is not recommended. Blackberries grown from seeds may not produce fruit or may produce fruit that is different from the parent plant.


Understanding Biennial Bearing


Blackberries are biennial plants, which means they produce fruit on the second year of growth. The first year, the plant produces primocanes, which are new canes that grow from the roots or crown of the plant.


These canes do not produce fruit but instead focus on growing and developing a strong root system.


In the second year, the primocanes become floricanes, which are the canes that produce fruit. After the fruit is harvested, the floricanes die, and new primocanes emerge for the next year’s crop.


Understanding the biennial bearing cycle is essential for proper pruning and maintenance of blackberry plants. Prune the floricanes after the fruit is harvested to encourage new primocanes to grow. This will ensure a healthy and productive blackberry plant for years to come.
