How long do you need to water new grass seed?

Answer 1

Initially, the first week you should water several times a day very lightly to keep the soil moist so the seeds can germinate properly...after a week, when you see the sprouts coming up, switch to once or twice a day unless hot and dry weather. After the grass has grown 3 or 4 inches tall, mow carefully and keep watering once a day for a few weeks....about an inch of water per week.

Watering New Grass Seed

Answer 3

If you have put straw on top of the newly sowed grass seed then you should water frequently to keep it moist at all times. When you see the grass starting to grow thru the straw continue to water frequently until the grass is tall enough to mow. Don't mow too short, it's young and tender yet. After the first mow water 1 or 2 times a week until it begins toughen up. ( or growing too fast) .
Most of the watering will depend on the type of soil and climate conditions and rainfall in your area. If you have lots of rain you don't need to water as often.

Answer 4

When you first spread the seed and the 1/8 inch or so of topsoil on it, water it a coupla-three times a day for a few minutes with a fine spray. This makes the seeds germinate and gives them crucial moisture for when they first sprout. After the area has become a completely green carpet of seedlings, you can water less often (once a day) but for a little longer (10 to 15 minutes). This is because the roots are getting deeper and you need to let the water soak into the ground deeper.

After the first mowing, you should gradually switch to watering every coupla-few days for more like 1/2 hour. Your goal is to get to the point where you are watering about once a week for an hour. That's the optimum amount of soaking to maximize root length and, therefore, drought resistance.

Actually, though, while it's more expensive, I highly recommend laying down sod. One problem with planting seeds is that you will have weeds pop up with your grass seedlings that you can't get rid of until you can walk on the grass. Also, with sod, you get an instant carpet of fully-developed grass and within 2 or 3 weeks you're into the watering-once-a-week cycle. I would never grow grass from seed again, except to repair brown spots or whatever. It's too much trouble and takes too long for the lawn to become established.

Answer 6

Keep the ground moist, until the seedlings start to estalibish then you should be able to cut the time in half. A great watering principle once est. is deep and infrequent so the roots will "dig deeper" chasing the water.

Note: over watering is just as bad ad under watering, make sure the ground stays moist not saturated. Give the soil time to dry some between watering Unless you are dealing with sandy soils which drain fast.

Answer 7

If the weather is dry water grass seed two/three times daily until you see the fine green shoots appear - then water once a day for about 10 days. Should be ok to survive on its own thereafter. x
