Clover and dandelion come to mind. But there's another category of weeds that we're not as familiar with. They're called winter annuals. And here are two good examples-Chickweed and henbit. Chickweed you'll notice is a lighter green color and it'll bloom with little white flowers, where henbit is taller and blooms with purple flowers.
Winter annuals germinate in the early fall.
They grow throughout the winter and complete their life cycle by blooming and setting seeds in the late winter and early spring. They leave behind a bare spot that's generally filled in by crabgrass. In fact, crabgrass and winter annuals act almost like a vicious tag-team of destruction in your yard. One filling in the bare spot left behind by the other. What we've got to do is end this vicious cycle.
