Did you see the teal-blue stuff sprayed on the vegetation next to I-695 between Timonium and Pikesville last week? It was a little weird, but also sort of pretty as every square inch of area next to the highway was blasted with the teal-colored gunk. The blue spray is a non-toxic fertilizer designed to jumpstart native grass growth. Since 2012, Maryland’s State Highway Administration has been eliminating the invasive plants choking our ‘roadway gardens,’ and replacing them with native plants.
