Habitat & Ecology
Chicory, like most invasives, prefers roadsides, fields and disturbed areas. It is often found along highway right-of ways. It can grow on many different soil types but is found on soils with high lime.
It has a milky latex that may cause dermatitis for humans. It can invade disturbed areas and native plant communities.
Mechanical treatment can be effective because it reproduces only by seed. Hand-pulling, digging and mowing is best for small infestations and must be completed before seed sets. Contact LRISS for more treatment information.
