Looks like mustard, smells like garlic, and grows like an invader: Coralville offers drop-off site for invasive plant

The City of Coralville offers a site to safely dispose of garlic mustard, an invasive plant species that can be difficult to eradicate once it is established. Drop off pulled garlic mustard plants in the dumpster marked “Garlic Mustard” at the Coralville Recycling Center, 110 E. 7th Street, until May 15. 

Garlic mustard can only be eradicated by pulling it out of the ground, and it should not be placed in yard waste bags or composted. Garlic mustard spreads rapidly, displaces native or other plants quickly, and its seeds can be easily spread by humans, wildlife, and nature. Because a single plant can produce hundreds to thousands of seeds, removing plants prior to seed production helps to manage this invasive plant.
