## Work of Interest to Maryland Green Gardeners

Baltimore Weed Warriors is a resource for Baltimore City gardeners interested in environmental stewardship through identification and removal of invasive, ecologically destructive plants.

Weed Warrior certification is free and open to all Baltimore City residents.The 3-part class curriculum includes: NNI plant identification (e.g. English Ivy, Porcelain Berry, Kudzu, & more), their impacts on Baltimore’s urban ecosystem, removal methods, and leadership training. Once certified, Weed Warriors are permitted to work in City Parks and remove NNI plants without the supervision of park employees. Classes are held in the spring and fall, with dates available several months in advance on their website.
