Spring is full of new growth — and there's no better time to identify and remove invasive plants than when they're just tiny seedlings. This FREE "brown bag" webinar focuses on the invasive seedlings from trees and shrubs to grasses and forbs that are easy to identify and hand pull, before they become mature plants and much harder to remove.
