Watering new grass seed

Over the years we have installed many lawns and renovated even more, we've seen and experienced both successful and not so successful seeding projects.  What we do know to be true is that effective water management is the key to getting new seed to germinate.  Too much, not enough or too late are all common problems.  Getting the right amount of water when the lawn needs it is essential to the success of the lawn establishment process. 

Grass seed may be installed into an existing or new lawn.  A new lawn is when we remove the old lawn completely, add soil, grade and hydro-seed to create an entirely new lawn.  A lawn renovation is a series of lawn care related services which will improve the health of the existing lawn, and this often includes over seeding the lawn to fill in thin or bare areas.  In either case, new grass seed is introduced into the lawn and now must fill in. 

An irrigation system is a helpful tool to have in getting a new lawn established.  However, be careful not to rely on it as if it's autopilot setting.  We often see over watering issues when an irrigation system is not managed properly and the owner does not make adjustments to account for the effects of weather or site conditions. 

More detailed watering instructions can be found here, which includes information about the first days of care through the first year.

Watering Instructions for a fall seeded new or renovated lawn:

The first few days and weeks are critical to getting your lawn established.  It’s important to water daily (morning is preferable to late day). Water for 10-15 minutes with an oscillating sprinkler, but not to the point where there are puddles. It is imperative to not saturate the soil, so focus on frequent yet light watering. You should be able to gage the soil moisture by walking on the lawn without sinking into it. Check soil moisture to see if shorter or longer time is necessary based on weather and site conditions. 

Newly seeded lawns require careful nurturing to ensure
successful establishment.  Over or under watering can
dimminish the desired results. 
With the new seed you’ll need to water daily for the next few weeks, at which time you will begin to water less frequently but for longer periods of time.  You can skip watering in the morning when we have had rain in the overnight. Do not skip watering even with rain in the forecast – as the weather forecast is not always accurate and forecasted rain fall amounts may not be sufficient. Please minimize the use of the lawn as much as possible during the establishment of the new grass.

Watering for spring seeded or summer seeded lawns will vary slightly.  The principal of keeping the seed moist remains the same, but you may need to water more or less frequently depending on the weather.  Establishing seed during hot periods of weather is risky - going for an extended period of time without moistening the germinated seed may put it at risk of drying out and dying as result.  Remember, too little water is just as bad as too much water.  Find the balance by checking moisture regularly and adjusting the watering accordingly.

Yes, there are improved turf grass cultivars that are less susceptible to disease. Diseases are naturally occuring in the environment, so if we can minimize the more favorable environmental conditions that promote diseases we can reduce the stress that new seedlings may experience.

I love natural lawn than any other artificial grass. Artificial grassing is getting more attention due to its easiness of maintenance. In recent I have introduced with http://www.lawnscience.com/ who are providing all sort of lawn support.
