UW-Eau Claire Students Test Natural Weed Killers for Gardens
6 Jul
Summary
- Students test solarization, mulch, and vinegar as alternatives to herbicides.
- City aims to reduce maintenance costs and support native plant growth.
- Research explores cost-effective methods for creating pollinator habitats.
University of Wisconsin-Eau Claire students are actively engaged in researching innovative methods to cultivate local pollinator habitats, moving beyond traditional herbicide use. The City of Eau Claire has recently designated approximately 93 additional acres for such initiatives, aiming to foster native plant growth and encourage native pollinator species.
This research, led by Associate Professor Nora Mitchell, involves students Ava Sieger and Abby Straub testing three distinct treatments on designated plots. These methods include solarization using black plastic sheeting, mulch application, and a spray of household vinegar (5% acetic acid), all designed to eliminate non-native vegetation.
Past efforts by the city have involved glyphosate to remove invasive species such as birdsfoot trefoil, a practice acknowledged as cost-effective but controversial due to environmental concerns. The current study seeks to identify equally effective, more sustainable alternatives.
Preliminary findings from the ongoing summer research indicate that all tested treatments are successfully reducing vegetation. While the acetic acid spray may require reapplication, the use of mulch is anticipated to add nutrients to the soil as it decays, potentially aiding future native seed germination.
The collaboration between UW-Eau Claire and the City of Eau Claire underscores a commitment to data-driven decision-making. If the initial 93 acres of pollinator habitats prove successful in reducing maintenance costs and providing ecological benefits, the city may consider expanding these conversions, guided by the outcomes of this research.
