Convert Lawn to Native No-Water Perennial Garden?  Without removing grass?



About 3 years ago I started deadheading wildflowers and mowing the seeds into my lawn. I mowed around the volunteers to help them thrive. Now, a sizable portion of my lawn is covered with native perennials, and I haven’t dug out any turf? One by one, I hope to start removing sprinkler heads.
