Hairy bittercress is a summer or winter annual that often shows up in such areas as landscape beds and poorly drained turf. You might also find it randomly popping up in your plant containers. It has four pairs of round leaflets and grows up to 12 inches in height. This weed produces small, white flowers that occur in clusters at the tips of the stems.
Because this weed projects small seeds when it's disturbed, you'll want to take preventative action to keep from having bittercress appear in the first place. Pre-emergent herbicides are the best method of control and should be applied to weed-free soil a few weeks after creating a landscape bed. Take care when pulling this weed from the soil as it can spread seeds easily and cause more weeds to show up weeks later.
