Not watering your lawn enough can also dry out and deprive your soil of nutrients, preventing good grass growth in the future.

When watering your lawn, be mindful of the weather. Overwatering can happen during stormy weeks if your watering schedule isn’t adjusted to accommodate weather conditions. However, your grass can dry out if you don’t adjust your watering schedule during sunny hot weeks. Finding a good water balance is essential to growing a thick lawn.
