Many so-called “weeds” — like dandelions, clover and violets — actually play a vital role in supporting local wildlife.
Dandelions bloom early in the season, offering nectar and pollen when few other flowers are available. This makes them especially valuable to pollinators returning after winter.
Clover provides plentiful nectar and pollen, attracting a wide variety of pollinators — from honeybees to native bumblebees.
Native violets are essential host plants for many fritillary butterflies: without violets, the caterpillars of these butterflies cannot survive.
When lawns are treated with broadleaf herbicides, we often remove more than just “weeds” — we erase important food sources for bees, butterflies, and other pollinators.
By choosing not to spray, you allow these plants to bloom — transforming a sterile lawn into a small but meaningful habitat, giving pollinators a chance to thrive.
