Blackberry plants are perennial berry plants that produce fruit on biennial canes, meaning the canes produce fruit the second year and then die. Blackberry plants come in two types: erect and trailing. Erect blackberry plants have thicker canes and can support themselves, while trailing blackberry plants have weaker canes and cannot support themselves. Blackberry plants are cold-hardy between zones 5 to 10, although erect blackberry plants can handle the cold better than trailing blackberry plants.
Choose a variety of blackberry plants that best suits your climate. If you live in a colder climate an erect blackberry plant would be better suited. If you live in a warmer climate, a trailing blackberry plant will do well.
Choose a spot in your yard to plant blackberry plants. They like full sun, although they can handle partial shade. They also need loamy, well drained soil.
Improve sandy or clay-like soil by adding compost or manure. Add 3 to 4 inches of compost or manure per square foot and work it into the soil to a depth of 6 inches.
Test your soil's pH. Blackberry plants grow best in acidic to neutral soil, pH 5.5 to 7.0. If your soil is too alkaline, add 30 lbs. of sulfur per 100 square feet and work it into the soil to a depth of 4 feet.
Plant blackberry plants in the spring to allow them time to adjust before the winter.
Dig a hole for the blackberry plants. Dig a hole as deep as the root ball and 2 to 3 times are large. Space each hole 2 feet apart. This gives each blackberry plant room to grow.
Place the blackberry plants in the holes. Fill the holes with soil and water the blackberry plants for 5 to 10 minutes.
Cut back any growth on the blackberry plants to 6 to 8 inches above the ground. This allows them time to focus on growing strong roots instead of producing fruit.
