After researching, I opted to eradicate the lawn with a process known as sheet mulching or cardboard mulching. Some refer to it as lasagna mulching because it requires making layers of cardboard and organic materials. I chose this method because it was inexpensive and had many benefits. The cardboard kills the grass while feeding the soil with organic matter, smothering weeds and trapping moisture. What could be better?
Over the years the plant has reseeded and slowly spread over one of my garden beds. I am amazed by the number of pollinators who visit to enjoy the nectar on the flowers.
