WHITE ROCK — Efforts are underway in White Rock to tackle the growing problem of invasive plant species.
According to the city's director of engineering and municipal operations, Greg St. Louis, the city has hired a company to come in sometime in the next few weeks and deal with knotweed sites all over the city.
"This stuff just grows really fast, it grows like bamboo and it takes over and can shade out native species and actually go through concrete as well as sidewalks and so it's very invasive and can take over an area quite quickly," explained St. Louis.
The city's arbourist, Alicia Otto, said it's not uncommon for knotweed to damage infrastructure, so the idea is to eradicate it in the city before it gets to that point.
"Some people have reported that it's destroyed walls in basements," she said.
Rather than spray harmful pesticides to kill the plants, Otto said the plan is to inject a harmful chemical into the stems of the knotweeds, ensuring the chemical gets down into the roots and leaves while minimizing any affect on the surrounding areas.
"Hopefully that will kill the plant and cease the spread," she said. "Next year we might have to do a few more applications depending on whether or not that's successful in killing it."
