You may soon see our grounds maintenance crews using a new technique to get rid of weeds. Foamstream is a herbicide-free solution to getting rid of weeds by using hot water
(208°F) and a plant-based oil to create a foam that covers plants. The foam creates a barrier keeping the heat in, giving it time to kill the leaves and move down the roots killing the
weed. The foam dissipates within 10 to 20 minutes and is harmless to people and animals. We will be using Foamstream in the City’s rights-of-way to start but additional
applications are in the works for some park areas.
