Removing invasive plants is equally as important as planting locally native ones. Invasives pop up endlessly in yards and can easily spread from one property to another, or worse, find their way into nearby natural areas — land that no one is maintaining.

Take a look the some of the literature we’ve linked to. The materials present photographs of the Mid-Atlantic’s invasive plants for easy identification and advises on the best methods of removal. For instance, Japanese stiltgrass is an annual grass with a narrow window of opportunity for controlling because of it’s growth pattern and the timing of its seeding.

Many invasive plants are commonly sold in big box stores and in local garden centers. English ivy and Bradford Pear are two highly invasive plants that come to mind. Learn which plants are ecologically harmful before you make a purchase and our natural areas will function better for it.
