How Invasive Species Impact Landscapes

Managing invasive plants and pests poses significant challenges and costs for nurseries, landscapers, and municipalities. Invasive pests like the Emerald Ash Borer have devastated urban forests, resulting in expensive tree removals and replacements. This not only leads to biodiversity loss but also compromises the health and resilience of these
ecosystems. Additionally, ornamental plants such as goutweed can escape cultivation, spreading into natural areas where they outcompete native species, lower biodiversity, and reduce habitat for pollinators and other wildlife including species at risk.
Best Practices for Nurseries, Landscapers, and Arborists
Use the Grow Me Instead Guide
Grow Me Instead is a key component of our PlantWise program, helping gardeners and industry professionals reduce the spread of invasive plants commonly sold in nurseries and recommending native or non-invasive alternatives tailored to each region.
Source Responsibly
Partner with recognized PlantWise retailers to ensure plants and seeds are sustainably sourced and free of invasive species.
