The City of Duluth is warning against a new invasive species that could be soon threatening the Northland.

An education session on Thursday focused on the removal and treatment of Japanese Knotwood, commonly referred to as "bamboo."

Technically, it is not bamboo, but it's tall, cane-like appearance bears a resemblance to the plant, both of which are from Asia. 

They warn Knotweed has an ability to survive floods, and quickly colonizes shorelines damaged by floods.

Duluth officials say the plant can grow to as much as 10 feet tall and dramatically changes ecosystems.

Experts say that chemical treatments are needed to control larger patches of the plant. They recommend cutting the stem about two inches above ground level and applying a 25% solution of Glyphosate. They say re-treatment may be necessary until the plant is weakened.  

In a press release, the city says it hasn't hit here yet, but "we are poised to suffer an explosion."

The next informational meeting on Japanese Knotwood is on Tuesday, July 23rd from 5:30-7 p.m. If you're interested, meet at the corner of Chester Park Dr. And E 9th St.
