Soil temperatures for optimal germination should be between 50 and 70 degrees for cool season grasses. Seed does not germinate at all well if the seed is planted deeper than 1/4 inch deep. As seeds are so near the surface, soil tempertures at the surface are closely related to the air temperatures. Recommended air temperatures for germination of cool season grasses varies from 60-85 degrees--KBG being at the low end and TTTF being able to germinate up into the higher temp. range. Cool season grasses take between 1 and 4 weeks to germinate. Seedlings need to then develope a root system and time to to get to the stage where they can store carbohydrates in order to survive freezing temperatures and winter dormancy. So seeding now will be a real crap shoot.
Dormant seeding is the second best process for lawn establishment. Seeding is done after temperatures fall (and will not rise until Spring) below the temperatures needed to induce germination (e.g. below 40) Usually sometime after Thanksgiving.

My lawn care company failed to tell me that the yellowy sections between fine greening up sections of my lawn were due to bent grass, and what to do about it - I only found out from getting estimates from other companies. Unfortunately, I had already tried to "beef up" those patches on my own with soil with fertilizer and new seed. Had to go zap the yellow stuff (including newly seeded patches) with Round-Up. We have had unseasonably warm weather a few weeks, and I was hoping to till and reseed now that the Round Up has just about done its thing. But, alas, hurricane-rains predicted for early next week! Is there any hope to be able to successfully plant this week-end if I cover with mulch of some sort? Or should I wait until spring - or even late summer?

Round up is a good idea as is tenacity for bentgrass. How about laying sod? I don't know how big an area your talking about but I am putting down 900 sqft on Friday n it cost me about $220.

For future reference, you can seed within hours of applying round up, it won't affect germination.

Thanks, hogan. Am surprised the sod option was not more pricey. Still - a little over my spending allowance for now.
Sorry about re-asking on the re-seeding post - (had forgotten I had posted here earlier!)

How is your sod faring at this point?

And - again, how does one work seed into the soil for dormant seeding?

The thawing and freezing cycles of the Winter season will work the seed into the soil.

Well I am keeping my fingers crossed for the sod. It's been 2 weeks and has not taken root. I guess if temps were warmer,it may have taken by now.
