Mowing at least once a week during the growing season is a good general rule. However, every lawn is different, and factors like frequent rain and fertilizer use can cause grass to grow faster, potentially requiring mowing as often as every four days. When you mow, always follow the 'one-third rule': never cut more than one-third of the grass blade's height at once, as this can weaken it and prevent it from taking in proper nutrients. For most grass types, the ideal height is around 2 to 3 inches, though some warm-weather grasses do better when kept shorter at about 1.5 to 2 inches.

Yes, you can overwater your lawn. While water is essential for growth, too much can be damaging. Overwatering keeps the soil saturated, which can suffocate roots, kill beneficial bacteria, and starve the grass of nutrients and oxygen, leading to root rot. This can occur due to a leaky irrigation system, a rainy season, or using a sprinkler too often. In addition to harming your lawn's health and longevity, overwatering can also increase your water bill.

If your grass is stressed from being over-trimmed, try watering it heavily and then allowing it to recover for at least two weeks before mowing again. If you notice brown patches where the grass has died off because it’s too short, you should remove the dead grass and overseed the area. Leaving dead patches can invite weeds and other problems, so if you want a totally green lawn, getting rid of dead patches should include removing the dead sections before reseeding the area.

Mowing a lawn will, unfortunately, not get rid of clover, and it may even encourage it to flourish. Let your lawn grow to a healthy height of over 3 inches and then set your mower blades no lower than this level. Higher grass will cut out the light that clover loves and discourage it from spreading.
