You need to water before you go to work, after work and maybe again just before dark.
In your case, you may need to get some straw to put over the seeds to help keep them moist.
Some rain will also help if it's not in the form of downpours!
Good luck!

Straw if heavily seeded areas or run your spreader with peat moss, multiple laps, may need 3-4 bags, depeding on yard size. Peat Moss works great for me when seeding. Straw gives me some weeds, but no big deal. You can kill off the weeds later.

You can buy a timer that will automatically water for you from Home Depot for about $25. Just set it and forget it.

Agree with jrodriguez90. Get the timer and set it to run every day for 15 minutes at breakfast, lunch, and dinner. When you see the grass sprouting, watch it. When it gets up to 4 inches high, it is time to mow and start backing off on the watering. Eventually you want to go to once a month watering in the cool season and once a week during the hottest part of summer.

Definitely get a timer. I got the orbit 4 valve timer from lowes (which is one of the best for the money). I can water all 4 stations multiple times a day and not even have to think about it!

Like dchall said though, only water 3 times a day until after your first mowing...then gradually work down to once a day...then work towards once a week (or for me in the desert I have to do it 3 times/week when it's 110 out with 10% humidity!).

I've had those timers they speak of, they work well. Now I have a sprinkler system, so it makes it ez.

"Did I waste my time and very expensive seed? "

With your current plan, you haven't wasted your time and money, but you haven't optimized it either. The closer you are to the ideal conditions, the better germination rates you will get. Watering once a day is OK. Watering twice a day is better. Watering 3 times a day is about ideal.

Just a note on first mowing: I wouldn't wait until it is 4" tall. Earlier mowing encourages lateral growth and will help the lawn fill in faster. I'd start around 2" and then work your way up just like you do watering.

Yep, I water 3 times per day. Once in the early morning, once around noon, and once around mid afternoon. This way the seed stays moist overnight, but the existing grass dries off b4 nightfall.

Thanks, guys for the advice, Yes, I thoughr about the timers,but I have a pretty big area to water, I would have to buy more hose,more sprinklers, etc. So I,m going to take my chances by doing what I,m doing. It,s calling for rain tonight, so that will help.

I have the same problem as the original poster. My current schedule is to water while the sun is coming up around 7:00-7:30(I have system where I need to move the sprinklers around, so I have to actively do it), then I water when I get home around 5:00. I will let you know how it goes using this method. I know it isn't ideal, but that's all I can really do.

Wish me luck.
