Officials in Indiana are sounding the alarm over the increasing population of the invasive kudzu across the state. Kudzu is mostly associated with the lower third of the state, and is now spreading towards the north, and fast.

Considered one of the most invasive plant species in the country, officials are now paying close attention to the weed spread after documenting it in more than 44 counties across the state. A big increase from 15 counties in 2005.
Why is the Kudzu Spreading Fast Across Indiana?
While Kudzu is not a new weed in Indiana, the spread has been slow over the past 20 years, mostly due to the local four-season climate. The harsh, cold winters, for instance, kill off the young growth before it can take hold and propagate.
However, the climate is changing, bringing with it milder winters. These warmer conditions allow the invasive weed to grow and thrive across different landscapes.
“We have seen Kudzu doing potentially better in some locations where it wouldn’t have in the past, which has added some more challenges”, said Will Drews, a nursery inspector and compliance officer in the Indiana Department of Natural Resources.
Why is Kudzu a Concern?

“Kudzu is a great poster child of showing what an invasive plant species has the capability of doing,” Drews has said.
The weed dominates landscapes, displacing once vibrant and diverse biodiversity into a green monoculture.
As it spreads, it poses more risks and challenges, such as:
- Ecological harm as it displaces native species and disrupts natural habitats.
- Reduced forest and plant health as the dense vines weaken trees and other vegetation, leading to greater susceptibility to other stresses.
- Increased property maintenance as homeowners battle to keep the weeds from encroaching on structures and damaging desirable trees and shrubs.
However, Indiana officials are hopeful in the fight against the insidious weed. They encourage more adoption of native plants in landscaping to minimize areas where Kudzu can grow and spread.
In areas with high infestations, it’s imperative that once the weed is removed, the landowners cover the areas with native grasses and forbs, eliminating the chances of Kudzu regrowth.
