Lawn Watering Tips

Proper Lawn Watering Practices

Rainfall cannot be the only source of water for your lawn. At some point during the growing season, you will need to water your lawn. If you do not have an in-ground sprinkler system, there is a variety of watering timers on the market that can make this job a little easier. Watering during seeding season requires unique watering practices.


  • Water in early am hours before the sun comes up – this will help prevent brown patch
  • Water 2-3 times a week
  • Water infrequently and deep – 3 to 5 inches
  • Use watering timer
  • Aerate


  • Water too much – Over watering can cause disease and root rot
  • Watering too often – causes weak grassroots
  • Watering middle of the day – when temperatures are high, water will evaporate before it’s able to be absorbed into the ground.

Factors to Consider:

Soil Conditions

– Hard compacted soil needs more watering due to water not being able to penetrate the soil. Missouri clay soil needs to be aerated to help loosen soil and help water penetration.  Sandy soils don’t retain water and need to be watered more often.

Grade of lawn

– Steep slopes need more water while low spots needless.


– More water is needed under trees due to branches blocking the rain. Mature Oak trees soak up to 50 gallons of water a day taking needed water from your grass.

Hot spots

– Grass near concrete, water meter pits, or rocks in the soil will need more water.


– Temperature, wind, humidity, and rainfall all play a role in your watering schedule.

Am I watering enough?

Place soup cans in the sprinkler pattern, and measure water depth in the cans. You are looking for .33-.5 inches of water per watering. Record how long it takes to reach this amount. Your lawn needs 1 to 1.5 inches of water a week. Split that amount over 2-3 watering.
