I've done the same, and now my yard is green year round because all that's left are native plants. My neighbor was bragging about his $300 water bill, then asked me what my secret was.

I let everything flower in the spring to let whatever survived the heatwaves, droughts, and freezes seed and outcompete the new stuff, then it gets mowed every other week at the highest setting.

I am about to seed some clover to help fix more nitrogen into the soil, though.

I just realized I can probably spray the yard with aquarium water after I do a change instead of pouring it down the drain.
