How to Get Rid of Berry Canes

Blackberries are delicious and the plants provide food and shelter for a variety of birds and animals. However, nonnative European varieties, including the Evergreen blackberry (Rubus acinatus) and Himalaya blackberry, (Rubus armeniacu), often become invasive and the plants suffocate and starve native plants. If allowed to grow unchecked, these plants develop thorny thickets, with one square yard of earth supporting as many as 50 canes. Blackberry canes are difficult to remove because the plants spread by underground roots and buds, and with the assistance of birds that scatter the seed. Usually, a combination of methods is required to remove the plants.

Instructions

  1. Manual Removal

    • 1

      Trim blackberry canes down to 6 to 8 inches, using garden pruners or loppers. If the canes are long, cut them to manageable lengths.

    • 2

      Insert a sharp shovel into the ground about 5 inches from a clump of canes. Push the shovel deeply into the ground. Lift the cane, along with the root, from the ground. Remove as much root as possible.

    • 3

      Cultivate the ground, using a rototiller. Permanent removal usually requires repeated tillage over several seasons. For small areas, you can use a hoe.

    • 4

      Check the area often. Pull new shoots as soon as they appear.

    Chemical Removal

    • 5

      Cut the canes close to the ground, using pruners or loppers.

    • 6

      Treat freshly cut blackberry canes with a systemic herbicide. Late spring or early autumn treatment is best, as herbicides are most effectively moved through the plants.

    • 7

      Apply herbicides strictly according to the manufacturer's recommendations. Your local cooperative extension office can advise which herbicide is best for your particular situation.

    • 8

      Evaluate the area often. Repeat treatments as necessary until blackberry canes no longer appear.
