Preferred habitats are open, sunny areas like forest edges, abandoned fields, roadsides and disturbed areas. Kudzu is extremely bad for the ecosystems that it invades because it smothers other plants and trees under a blanket of leaves, hogging all the sunlight and keeping other species in its shade. It will, however, invade well-drained acid-soil forests as well as the floor of a closed canopy forest. Including bamboo, kelp and corn, kudzu can grow up to 1 foot (12 inches) a day. Because kudzu produces stems that can grow to 20 m (60 ft) in length with extensive roots, it has been used to control soil erosion.
