Fall is the best time to plant trees (from what I gather, since this is the lawn forum). Fall is also the best time for seeding a new lawn. I would seed ASAP after the sprinklers are in.

1. Water the bare soil 3x per day very lightly trying to germinate as many weed seeds as you can.

2. After a week spray the new crop of weeds with Round Up.

3. Continue watering for another week to get the stragglers.

4. Spray again if necessary.

5. Scatter your seed.

6. Roll the seed down with a rented water fillable roller.

7. Resume the light watering 3x per day. Continue that for 2 weeks for rye, 3 weeks for fescue, and/or 4 weeks for Kentucky bluegrass. These seeds have different germination times. If you have a mix of rye and KBG and you stop watering after a week or two, you'll have 100% rye grass and no KBG.

8. When the grass shows about 80% germination, start to back off on the watering frequency and start measuring the amount you apply. The mantra for mature turf is to water deeply and infrequently. You won't be there until next year. For the rest of this year you'll have to baby it some trying to get deep roots by watering deeply and sort of infrequently.

Dchall, Thank you so much! You have told us exactly what I wanted to know, yet far more than I expected. Thanks for sharing your knowledge.
