In the early spring here in the mid-Atlantic region, I started to see some common weed activity. What is very visible this time of year is wild onion and wild garlic. Wild garlic (Allium vineale)and wild onion (Allium canadense)are winter perennials. They emerge in late fall from underground bulbs and grow through the winter and spring. In late spring, aerial bulblets are formed and the plants die back in early summer. The underground bulbs can persist in the soil for several years.
