Mowing your grass to the proper height is the single-most important thing you can do to improve the health of your lawn.
When you mow, don't rake clippings — leave them on the lawn instead. However, be sure to sweep up your sidewalk, driveway or street.
Get your soil tested to determine the right mix of fertilizer for your lawn. You may need less than you think.
The best time to water is in the early morning hours before 10 a.m. Grasses naturally grow slower in the summer, so brown grass usually means your lawn is just dormant, not dead.
Weeds can tell you something about what's wrong with your lawn. Take time to identify your weeds and treat them appropriately to strengthen and improve your lawn. A weed-free lawn is not necessarily a healthy one.
