  • This plant can reproduce both by seed (through the berries) or vegetatively through root fragments.
  • Animals and birds can spread blackberry seeds through feces.

Status in the CKISS region

  • Cutleaf blackberry is present in the region with limited distribution, so eradication is feasible.
  • CKISS is taking steps to monitor and manage cutleaf blackberry.

Integrated pest management options


Mechanical Control

  • Hand-pull small, young plants.
  • Dig up the root crowns of older plants.
  • Cutting thickets low to ground may be required to avoid working near thorny brambles when accessing roots.
  • Cutting alone is not as effective as digging, but if repeated continuously over a number of years it can eventually deplete the root reserves of the plant.
  • In some cases, grazing by goats has helped control populations.
  • Note that birds may nest in blackberry thickets. If this happens on your property, take care to conduct removal activities outside of their nesting period.
