Intentional invasions come from mismanagement of plants.
If you have a water feature or garden, don’t forget about invasive aquatic plants like hydrilla.
Early detection and identification of invasive weeds are important to prevent further spread.
Another great source of information is the land-grant institution’s Extension Service in your state.
Look for leaves that stay green into late fall.
The absence of living native plants means that treating invasives withchemical herbicideswill cause much less collateral damage.
The plants can also be smothered by covering the area with heavy-grade black plastic.
Invasive plants should not be added to a compost pile because they can take root or deposit seeds.
Once collected, many states have regulations about the disposal of invasive plants so they are nonviable.
Contact your local Department of Natural Resources or Agriculture for instructions.
Chemical control options
The cut-and-swipe method combines manual and chemical removal.
For large areas of invasive weeds, herbicides are usually the most effective treatment.
Triclopyr is a selective herbicide that only affects broadleaf invasive plants.
It will not damage grasses.
Always follow the label directions carefully.
