MADISON (WKOW) — When talking about weeds, you might hear these terms: aggressive, invasive, or noxious. They are often used interchangeably, but they actually mean different things.
Aggressive plants crowd their neighboring plants. They’ll take over the entire garden if you leave them unchecked.
Invasive plants do that too, but they also leave the garden and invade our natural ecosystems. They crowd out native plants that birds, insects, and other wildlife depend upon.
Noxious weeds are plants that have been identified as harmful to people, animal, crops, and the environment.
