Wild Onion

These perennial weeds smell like their namesakes, and there’s no mistaking their presence when you mow over them. Wild onion has flat leaves, while garlic is round. They both grow from bulbs and form clusters similar to chives. To remove them, avoiding hand-pulling. It only serves to separate the main bulb from the tiny bulblets surrounding it, which remain in soil and sprout. To dig wild onion or garlic, excavate about 6 inches deep to get the whole bulb. Otherwise, spray with herbicide. The kind that kills nutsedge works on wild onion and garlic. In late spring, these weeds produce small bulbs atop long stems. Snip these and destroy them. They contain new bulbs—they’re this weed’s way of spreading and covering new ground.
