Choosing the Right Blackberry Variety

When selecting the perfect blackberry variety for your garden, there are several factors to consider. The choice between thornless and thorny blackberries, as well as everbearing and summer-bearing types, can have a significant impact on your growing experience and the resulting harvest.

Thornless vs. Thorny Varieties

Thornless blackberry varieties, such as 'Apache’, 'Arapaho’, and 'Navaho’, offer a more user-friendly option. These plants are easier to handle and harvest, making the gardening process more enjoyable. On the other hand, thorny blackberries, like 'Brazos’ and 'Darrow’, may produce larger and sweeter fruit, but can be more challenging to manage due to their prickly stems.

Everbearing vs. Summer-bearing Varieties

Everbearing blackberry cultivars, including 'Prime-Ark Freedom’ and 'Prime-Ark Traveler’, provide two harvests per year – a smaller spring crop and a more substantial fall yield. In contrast, summer-bearing blackberries, such as 'Chester’, 'Natchez’, and 'Triple Crown’, offer a single, bountiful harvest during the summer months.

Summer-bearing Blackberries Offer a single, bountiful harvest during the summer months.

Planting Blackberries

When planting blackberries, choose a location with full sun (at least 6 hours of direct sunlight per day) and well-draining soil with a pH of 5.5 to 7.0. Avoid low-lying areas where water tends to settle, as this will lead to rot and disease. Plant bare root blackberries in early spring, while they are still dormant, to reduce transplant shock. Container-grown blackberries can be planted anytime during the growing season. Space plants 3 to 5 feet apart in rows that are 8 to 10 feet apart, and plant at the same depth as they were previously growing.

Caring for Blackberry Plants

Proper blackberry plant care is essential for healthy and productive plants. To ensure your blackberries thrive, follow these essential tips:

Watering

Blackberries require consistent moisture, so provide them with 1 to 2 inches of blackberry watering per week, either through rainfall or supplemental watering. Avoid overwatering, as this can lead to root rot and other issues.

Fertilizing

Apply a balanced fertilizer in early spring and midsummer to support the blackberry fertilizing needs of your plants. Additionally, top-dress the soil around the plants with a layer of compost annually to provide essential nutrients.

Pruning

Prune your blackberry plants in late winter or early spring, removing any dead, damaged, or diseased canes. This allows the new, healthy canes to produce a bountiful blackberry pruning crop. Be sure to leave the new canes to bear fruit.

Trellising

Install a trellis system to support the canes and make harvesting easier. Train the blackberry trellising canes onto the trellis as they grow, keeping them upright and organized for optimal fruit production.

Harvesting and Storing Blackberries

Knowing when to harvest your blackberries and how to properly store them is crucial for enjoying the full flavor and texture of this delightful fruit. By following a few simple guidelines, you can ensure a bountiful blackberry harvest and extend the shelf life of your blackberry storage.

Harvesting Blackberries

For maximum sweetness and ripeness, wait until the blackberries have fully swelled and developed a deep, glossy black color before harvesting. Gently pluck the fruits from the canes, taking care not to crush or damage them. Collect the blackberries in a shallow container to avoid bruising the delicate skin.

Storing Blackberries

Blackberries have a relatively short shelf life and can easily become overripe or spoiled. To extend their freshness, store blackberries in the refrigerator, unwashed, in a single layer on a paper towel-lined container. This helps absorb any excess moisture and prevents the blackberries from becoming mushy. For longer-term storage, freeze the blackberries by washing them, removing the hulls (stems), and placing them in a single layer on a baking sheet. Once frozen, transfer the blackberries to an airtight container or freezer bag for up to 12 months.

Growing blackberries through the year involves several key steps. First, choose a location with full sun and well-drained soil, and plant bare root or container-grown blackberry plants in early spring. Provide consistent watering, regular blackberry cultivation, and proper pruning and trellising to support the canes. With the right care and attention, you can enjoy bountiful harvests of delicious, homegrown blackberries.

Blackberry Varieties and Cultivars

When it comes to growing blackberries, gardeners have a wide array of blackberry varieties and cultivars to choose from, each with its own unique characteristics and attributes. Some of the popular types of blackberries include the 'Adrienne’, a cultivar known for its delicious fruit on strong, thornless stems, and the 'Black Beauté’, which boasts sweet, fragrant berries with relatively few prickles.

For those seeking a more ornamental option, the 'Loch Maree’ cultivar offers a stunning display of pretty pink flowers, followed by a generous crop of juicy, thorn-free berries. The 'Loch Ness’ variety, on the other hand, is prized for its vigorous growth and high yields of large fruits on long, thornless canes. And for gardeners who prioritize ease of harvesting, the 'Merton Thornless’ cultivar delivers large crops of well-flavored berries on a compact, thornless plant.

Regardless of the blackberry variety or cultivar you choose, these adaptable and productive plants can be a rewarding addition to any home garden, providing a bountiful harvest of delicious, nutritious berries year after year.
