Bohemian Knotweed

Also known as Fleece flower, Mexican bamboo or Elephant ear bambooinject (1)
(Fallopia x bohemicum or F. x bohemica or Polygonum x bohemicum)
 
Quick ID:

 

  • Grows to heights of 6-10 feet
  • Stems are smooth, bamboo-like and stout
  • Stems are hollow, but may be water-filled depending upon soil moisture and time of year

Habitat:

  • Found in parks, gravel bars, along riverbeds, stream banks, rights-of way, and roadsides. It is also found in riparian areas and will move up river columns.

How It Got Here:

  • Originated from Asia and spread west for the last few hundred years (primarily by fragmentation)
  • 10mm of plant can re-grow to maturity.
  • Bohemian can propagate by fragmentation and seed which explains the rapid movement across North America.

Reasons for Concern:

  • Can invade and thrive in a variety of habitats with no natural predators or control mechanisms.
  • Japanese and Giant Knotweed have evolved into the Bohemian variety found in North America.
  • This species is now on both coasts to propagate by seed and fragmentation.   This likely explains the rapid progress observed in the Americas as opposed to the rather slow progression of the UK and Asiatic strains.  
  • Knotweed rapidly reproduces through seeds, rhizomes, and will move quickly down a riverbed and create one solid monoculture infestation.
  • Canes can sprout through 6 inches of concrete or asphalt and will damage roads & foundations to the extent they need to be replaced.

TREATMENT WITH JK1000

  • Calibrate JK1000 to deliver 5mls
  • Inject into cane above 2nd node at 5mls per cane of a concentrate Imazapyr or Glyphosate herbicide.
  • Let herbicide translocate into roots before removing canes (72hrs).
