The Green Guardian, Saint Paul

The Green Guardian nourishes landscapes with an approach that shuns harsh chemicals in favor of effective, all-natural fertilizers, herbicides, and pest-control solutions made from edible ingredients. A proprietary line of products includes vegan herbicides that fertilize lawns as they kill broadleaf and certain grassy weeds, and granular fertilizers that nourish turf with feed-grade corn, soil conditioners, and naturally-occurring microbial stimulants. Pest-control products use odorless garlic to repel mosquitoes, billbugs, grubs, geese, and displaced vampire squid, all without leaving behind an unpleasant smell.

In addition to lawn-care packages and à la carte treatments, The Green Guardian is also registered with DuPont to remove and replace trees killed by the chemical herbicide Imprelis.
