Hairy bittercress is a winter or summer annual depending on its location. It initially forms a basal rosette. The initial true leaves are heart shaped, followed by leaves which contain 2 - 4 alternating leaflets. The surface of the leaves is often hairy. Hairy bittercress forms stems that are smooth and erect, usually branched at the base with few leaves. Hairy bittercress spreads by seed. The seed capsule is up to 10 times longer than it is wide. The capsules will |

Cultural Practices:
Hairy bittercress is an annual weed which is found on wet disturbed areas.
It does best on sandy to organic soils. It can be found in landscapes,
turf and in container plants. Allow soils to dry or correct drainage to
prevent soils from remaining moist.
Herbicide Use:
Make your postemergent herbicide application when hairy bittercress is
young and actively growing. For best results, treat during rosette stage.
