I made my fortune as a child by growing dandelions. My father saw them inflicting havoc on his beautiful green lawn. He paid two cents per pulled dandellion, provided that the roots were also up. I was guaranteed employment because my neighbors let their dandelions grow to seed. This meant that there were always more for us to pull.

I can still remember the annual lawn care ritual: The spreader delivering different powdery compounds to the grass, the mowing and the watering. I mowed the lawn when I was old enough for the starter cord to be pulled. Even though the lawn was completely flat, we had a loud, gasoline-engine powered lawn mower.

The lawn was used as a play area by the children. Mothers complained about their children’s grass-stained clothes. But everyone wanted a large yard for their children to play in. It was a time for innocence. It’s now a time when there are consequences.

If you care about the preservation and protection of our native wildlife and pollinators, you should consider that turf grass provides very little habitat for pollinators or other animals or plants that make up a healthy, diverse ecosystem.

How much lawn do you really require? Are you a parent? Are they yard-playing ages? You can keep some turf for them. You don’t have to worry about the weeds your kids might trample the lawn. Do your children really need a quarter of an acre of grassy terrain?

How to kill your lawn

If you don’t need as much lawn, you might consider cutting it down or replacing it with native flowers. However, it is much more difficult to kill a lawn than you might imagine.

Non-toxic products are not always cheap and often kill the above-ground vegetation. Horticultural vinegar (20% acetic acid), will burn the above ground vegetation, but the roots will laugh and grow new blades. Concentrated acid can cause severe eye irritation, permanent corneal injury, and skin burns.

Vinegars containing more than 11% acetic acids can also cause severe eye injury and burns, leading to blindness. Only systemic products-those that kill the entire plants-work.

However, this may not be an option for anyone who is alarmed by recent events. Jury decisions linking non-Hodgkin’s lymphoma to glyphosate use.

Montgomery County residents have a lucky escape. The county has changed its nuisance laws to allow naturalized lawns. This was after realizing that wild gardens can improve air quality, soil quality, and reduce stormwater runoff. Fairfax County’s regulatory code prohibits wildflowers from lawns.

The District encourages the planting of pollinators in residential yards. However, it also requires that weeds greater than 4 inches in height be removed (it doesn’t define what a “weed”). DC’s Green Yards Recognition Act of 2016 covers pesticide practices and the use of certain types of leaf blowers and lawn mowers, but doesn’t mention replacing lawn with native vegetation. The Department of Energy and the Environment will create a new webpage that will provide all of the information required by law about Green Yards.
