    You may get some germination, certainly not what you should expect had they not treated the lawn before you got there. Maybe the customer will be willing to have the lawn reseeded in the spring and they can be told in advance to hold off other treatments.

    A lot depends on what chemicals were applied. If there was a pre emergent in addition to a post, your seed won't germinate. If their target was existing broadleaf weeds only, you will get some germination.

    Germination shouldn't be a big problem, highly doubtful they are using a pre-emergent this time of year, more than likely just a feritlizer, but even if it had some broadleaf killer in it, should not affect the seed. If the weed had been sprayed ten days ago, it should have been beyond the "curling" stage.

    I would read the lable of many weed controls, most have a reseed date well after 10 days, more like 45-60 days.

    I have been burned by this in the past. VERY frustrating to seed lawns treated by ohters.

    I reseeded a lawn last year that had been treated by another company. No treatments for the last 30 days -- but.......there was no germination from initial seeding. Comapny had sprayed 2-4d. ReSeeded in late October --- great results!

    Around here tgcl is putting down primarily fertilizer, since he doensn't have access to the invoice, and I know that you shouldn't assume anything, but my guess would be that there isn't any weed killer in the application.

    First you need to find out if Tgcl did a granular/spot-treat weed app or a straight liquid app, if they did a granular app you chances are much better, if they did a liquid, I highly doubt they would be putting down just fert, so chances are there was a herbicide in there and you are probably out of luck, but you never know

    This is a new account ,they just moved in .Lawn looks typical of a new builder seeding job .They never mentioned tgcl .They had only 2 broadleaf weeds in the newer turf .I didn't see the Curling weeds until I was half way through the power salsco slice seeding job. since the customer doesn't have the invoice , can only speculate they are using a spray 46-0-0- and 3way herb which is typical for service in our area. since the weeds are curling I'm hoping i will get some germination .
