Lawn care must do: Water infrequently
This will force your grass roots to go deep into the soil. Deeper than most weed roots. As the top few inches of soil becomes bone dry, the weeds and weed seedlings up there die while the grass still enjoys moisture from a little deeper.
Shallow, frequent watering encourages “thatch” (the grass propogates with above-soil runners (like strawberry runners) rather than rhizomes under the soil – there gets to be so many runners that they weave a mat that chokes out water and air). Since the roots are in the top inch or two of soil, a hot day will quickly dry the soil and much of the grass will brown. Weeds and weed seedlings looooove a daily watering. It’s just what they need for a good start.
