These giant berries are powerhouses filled with antioxidants and beneficial phytonutrients that will blow your mind

Blackberries are hardy plants that are relatively easy to grow. However, growing from seed won't produce berries the first year.

The seeds require stratification in the first year and will grow in the second year. Blackberries are hardy plants that rarely contract a disease or attract pests.

These Mammoth sized dark black meaty berries are one of the largest blackberry fruit in the existence. Huge produce, a good crop year after year with an amazing flavor.


The trailing type requires supports to train canes to grow up and out (naturally grows toward the ground). Disease resistant. New canes can be trained right up through the older floricanes without needing to prune out old canes first, and without any disease problems. Giant berry has great flavor and aromatics. Deer and rabbit resistance. Mature at 5-6 feet. Shows excellent resistance to heat damage. Harvest from late June until the end of July

With a mildly sweet flavor that's perfect for salads, smoothies, jams, and desserts, you can enjoy bountiful yields of thornless, easy-to-pick berries all summer long! Simply provide full sun and well-drained soil. Resistant to heat, disease, and hungry critters, Blackberry Columbia Giant is ready to prove that sometimes more is more!

Species: Mostly Columbia and Kiowa. There are other varieties that can be also in the packet. Height: 5-6' Spread:3-4' Light Required: Full Sun Blooms: Late Spring Zone: 3-10 Form: Edible, Perennial Flower Form: Fruit Soil Requirements: Well-drained, rich, slightly acidic moist soil, 5.5- 6.8 pH. Soil Requirements: Loamy Soil Pruning: Trim canes to 4' - 5', remove unwanted ones Early spring. When the new shoots of erect blackberries reach thirty to thirty-six inches in height, cut off the tips. This will force branching lower on the canes and will cause the canes to thicken, making them better able to support a heavy fruit crop. During the winter, prune the laterals to twelve to fourteen inches for convenient harvesting and larger berries. In late winter, remove any remaining dead or weak wood. Leave healthy, vigorous canes spaced at six canes per linear foot. Foliage: Green, Thornless, upright canes

Excellent fruit size Disease-resistant canes Tolerates heat and humidity May produce a second crop in fall Known for its flavor, vigor and productivity Extra-sweet, huge berries Thornless for easy picking Semi-erect canes Dense foliage protects plants from sun scale

-- Information on blackberry seed stratification: Blackberries are hardy plants that are relatively easy to grow. However, growing from seed won't produce berries the first year. The seeds require stratification in the first year and will grow in the second year. Blackberries are hardy plants that rarely contract a disease or attract pests. Place the blackberry seeds in a resealable plastic bag along with a handful of damp peat moss. Seal the bag, and place it in a refrigerator with temperatures around 33 to 35 degrees Fahrenheit. Keep the seeds chilled for 12 to 16 weeks

Fill seed trays with seed starter soil, and spread the blackberry seeds on top of the soil. Lightly cover the seeds with soil, and place in a warm area. Blackberry seed germination does not require bright light since the seeds are covered with soil. Mist the soil with water in a spray bottle whenever the soil begins to dry out. Once seedlings begin to sprout, move the tray to an area with bright light.

-- How to Germinate Blackberry Seeds Step 1 Lay a single layer of blackberry seeds along one end of a paper towel. Fold the paper towel in half over the seeds and slip it inside a sealable plastic baggy. Seal the baggy and place it in the bottom drawer of the refrigerator for 30 days. The temperature must be kept around 35 degrees Fahrenheit during this time.

Step 2 Mix equal parts potting soil and compost. Add 1/4 cup vermiculite for every 2 cups of soil mixture and mix it thoroughly.

Step 3 Fill the peat pots with the potting soil mixture and lightly press it to eliminate any air pockets. Water the soil until very moist but not sopping wet.

Step 4 Create a 1/4-inch deep depression diagonally across the top of the soil. Sprinkle three seeds within the depression, then pinch the soil closed. Spritz the soil several times with a spray bottle.

Step 5 Cover the top of the peat pot loosely with clear plastic wrap. Place the peat pots near a sunny window or outdoors in a warm area protected from the wind.

Step 6 Water the seeds with a spray bottle every other day for 15 to 20 days or until germination. Once the seedlings have reached 4 inches in height, they can be planted outdoors.

-- How to Grow Blackberries From Seeds Step 1 Place damp peat moss in a sandwich bag and put seeds in the peat moss. Close this and put it in your refrigerator for 3 to 5 months. The temperature must be between 33 to 35 degrees F to stratify the seeds. The seeds should start to open up in the cold.

Step 2 Plant the seeds in a flowerpot with stones or broken terra cotta in the bottom for drainage. Use soil made for fruit and mix it with compost. Keep the seeds moist until they start to sprout. Mix in more compost about every month and water when the soil starts to feel dry.

Step 3 Plant outside the next spring. Place the plants in full sun to partial shade in well-draining soil. Place a trellis behind the plants to help hold up their canes. Dig out the hole large enough so as to not bend the roots and mix soil with compost before planting the seedling. Plant the plants 2 feet apart with rows up to 7 feet apart. Keep mulch on top of the soil around the plants to keep out weeds and hold in moisture.

Step 4 Keep canes trimmed to about 7 feet. In the second year, trim the canes that have produced berries to the ground and cut off suckers that have grown outside the rows.

Step 5 Pick berries when they turn dark black or purple in color. Pick up any berries that fall to the ground.
