Watering & Mowing

Watering & Mowing Newly Seeded Lawns

Our Lawn Renovation Services include overseeding with a mix of rye and fescue grass seed to thicken your lawn. To help the seeds grow, we apply a seed cover of biologically active organic mulch. You can walk carefully across your lawn, but please avoid a lot of foot traffic. We recommend waiting until after the 2nd mowing before allowing dog play and regular foot traffic.

Watering New Grass Seed

Watering is crucial for seeding success. The seed, soil, and mulch must stay moist. Water twice daily (more if conditions are extremely hot/dry, less if we receive adequate rain) to ensure the top 1 inch of soil stays moist. It is critical to keep the seed moist throughout the germination period which could be anywhere from 5 to 15 days. Continue watering twice daily until you have mowed the new grass 1-2 times. Once your new grass is established, you can go back to a normal watering routine. During the first season of your new grass, you must water throughout the hot summer months using the “Watering Your Established Lawn” instructions below.

Watering an Established Lawn

Try this “rain gauge” technique using an empty tuna can. Run your sprinkler and see how long it takes to get a half inch of water in the can. Usually it’s about 30 minutes. Traditional Lawns need at least 1 inch of water per week to stay green (rainwater and sprinkler combined). Alternative Lawns need less. So 20 minutes, 3 times per week will add 1 inch of water on your lawn. Water deeply 2-3 times per week, rather than daily. Water as early in the morning as you can, when possible. If you can’t push a 6 inch screwdriver into your lawn, you’re not watering enough. Watering depends on root depth, grass type, soil conditions, and weather. For more advanced watering schedules, see “Smart Watering: Cycle ‘n Soaking”.


You should start to see germination within a week or two when the temperatures stay above 55 degrees. Wait to mow your lawn until the grass blades reach 3 to 3.5 inches in height. This could take up to 8 weeks (about 2 months), so plan your mowing schedule accordingly. We highly recommend mulch mowing (not bagging the clippings) as a best practice for building your turf. Grass mulch makes excellent food for the microbes living in your soil. Make sure your mower blade is nice and sharp and cut your grass only when it’s dry. Avoid mowing your lawn too short, maintaining a 2 or 3-inch height. Lawns that are mowed too short not only invite invading weeds and pests, but also puts a strain on the moisture content of the soil. Longer grass blades also capture more sunlight which strengthens plant health.
