Years Of Experience

Focused Protection for Minnesota Landscapes

South Lake Ash Shield was built to help Minnesota homeowners protect valuable ash trees from the serious threat of Emerald Ash Borer. This invasive insect can damage ash trees from beneath the bark long before obvious warning signs appear, making early evaluation and preventative treatment extremely important. Our goal is to help healthy ash trees withstand the outbreak, preserve shade and curb appeal, and reduce the risk of unsafe falling branches or costly tree removal.

Led by owner Erik Lemke, South Lake Ash Shield combines professional tree care with trusted horticultural experience. Erik is a University of Minnesota Horticultural Department graduate with years of hands-on experience as a golf course superintendent and senior gardener at the Minnesota Landscape Arboretum. Fully insured and licensed through the Minnesota Department of Agriculture, we provide honest landscape evaluations, clear treatment recommendations, and professional pesticide injections designed to protect ash trees for up to two years.
