Turf researcher Sara Stricker says leaving your lawn to the dandelions might not be the best course of action for helping native pollinators. But not everyone thinks it's the best way to help pollinators. Stricker said the number one weed in Canadian lawns is dandelions, but they are not designed to feed native pollinators. He said dandelions are not that nutritious for pollinators and they prefer native plants and shrubs as a food source. "And at least trying to help pollinators on a section of your lawn is a good idea."
