Managing invasive plants can feel overwhelming, whether you’re working alone or helping someone else get started. However, breaking the project into smaller steps can make it easier and help you stay on track over time.
To begin, do some research before adding new plants to your yard or garden. Check the Wisconsin Department of Natural Resources website for a list of restricted and prohibited plants. The site includes helpful information about how to identify invasive plants and how to manage them.
Next, look at your own landscape and note any invasive plants that may be growing there. The DNR has videos to help you identify both aquatic and land-based invasive species. Removing all invasive plants may not be possible, but you can reduce their spread. Cutting back plants like Dame’s rocket and forget-me-nots before they seed helps contain the problem. Start your control efforts where you see the fewest invasive plants. Then, move toward areas with more growth to avoid spreading seeds.
There are several control options: manual, mechanical, cultural, or even biological methods. Knowing how a plant grows and spreads helps you choose the best method for your situation. Digging and pulling works well for small plants, especially in sandy or damp soil. Tools like weed wrenches can help pull out bigger plants such as buckthorn and honeysuckle. Covering plants with tarps or old carpets can also work. This method blocks light and kills plants underneath—whether invasive or not. Before covering, mow or cut plants and leave the cover in place for at least one season. You can also manage crown vetch or goutweed by mowing them once or twice each year. This method takes several years, but it can slow or stop the spread.
In some cases, using herbicides may be the best option. The type of plant, its size, and nearby plants will guide your choice. Apply herbicides to bark, cut stumps, or leaves based on the label directions. Always read and follow the label for safe and effective use.
Once plants are removed, dispose of them properly so they don’t grow back. Many towns allow bagged invasive plants to go in the trash if they are labeled clearly. Check with your local office for disposal rules.
Finally, keep an eye on your yard throughout the year. Pull new sprouts as soon as you see them. Seeds can stay in the soil or blow in from nearby areas for years. By taking small steps, you can make a big difference—one plant at a time.
