Chickweed

Chickweed is another very common winter annual weed.  They germinate in the fall and overwinter.  In the spring they become noticeable with excess growth.  There are two chickweed species in our area, common chickweed and mouse ear chickweed.  Both grow low to the ground and have small, oval leaves with tiny hairs that are oppositely arranged around the stem.  The mouse ear chickweed has more hairs on the leaves and really look like mouse ears.  Chickweed is best controlled in the fall.  It has a shallow root system that is easy to pull in the spring.
