    I said the same thing as you did. He made no mention of having applied Pre-em so I didn't mention it. I'm sure most here know that Fall is the optimal time to seed. The OP has already seeded and all he asked for was a little help explaining to his customer why the seed hasn't germinated yet.

    There is no magic to planting in the Fall. The seed will come up the same in the Spring as it does in the Fall. The difference is the new grass stands a better chance of surviving the Winter than it does of surviving the Summer.

    Unlike the northern areas where you live, in the real South, seed is planted in the Spring, not the Fall.

    I wouldn't brag about only seeding in the Fall, and spreading Pre-M way before it is needed,, then CALLING OTHERS inexperienced...
    I don't use pre-m in lawns,, ever,,, and we don't get CG either... I have successfully seeded every month of the season over the course of my career, to eliminate dirtspots or thin areas wherever needed...

    Experienced landscape artists ALWAYS focus on growth,,, and those who can not make things grow focus on killing things... lawns should MATURE to the point of requiring very little input to remain PERFECT... :)

    First off, thanks for the responses. Second off, I'm not an idiot. I know that it won't germinate when it's that cold. But the temp I stated that was 33-35 was ONE night. Also, HERLER, I take care of their lawn care schedule. I didn't apply any pre m or weed killer for this very reason.

    The customer knew before hand that it would take consistent watering and weather conditions to be right. So far we have had unseasonal weather.

    I'm not searching for complete bs to tell this guy. He has already been told that the weather hasn't been suitable for growing conditions and to wait it out.

    Yup, it is. There is a difference between an educated guess using available data for the area and an uneducated guess using nothing, the latter being the prominent method used on this site.

    I also stated a full site audit is needed here as well. So where exactly did I contradict myself?

    Was it when I said this?

    or this?

    or this?

    I think you are confusing HC with me. He is the one who said I couldn't help nor could I possibly know anything about the area because I am 3000 miles away. Further, you can help someone without seeing the site, you however can't give them an informed final solution without site data. I provided the OP with the information necessary to make an informed professional decision (per your complaint), once he collects the necessary data from the site.

    Perhaps you can demonstrate how to solve those equations without data from the site?

    My mistake Kiril. I think you might have misunderstood what I meant by my original post. I said thousands of miles not in reference to you but because I am very far from the OP. I am not familiar with his area, the ground, the weather, nor am I privy to the water schedule the homeowner adhered to. Yes, I could look up observed weather and soil conditions for the area but chose not to. I dislike seeing advice on water schedules, fertilizer application, pesticide application, knowing the advice is being given with many unknown variables.

    We are bickering and I think we generally agree with each other.

    Because KBG is so slow to establish, I like to mix in a small % of high quality PRG. This has two purposes: (1) it makes the customer happy to see some germination and (2) more importantly, if the PRG hasn't come up after about 7-10 days of acceptable weather, it's an early warning sign that something may have gone wrong with the seeding overall. Of course, even PRG won't germinate if it's freezing at night, so some judgment is required also.

    Keynes is right. Kentucky bluegrass is just too slow for many homeowners--they expect more rapid results from a professional. And a cold spring with a frost event makes it worse. Even after 8 weeks, KBG may only be a half-inch tall, and probably be thin. And the owners seldom water as much as they say they will. If they want KBG, the answer is sod. There is a good chance they already have a high percentage of perennial rye in the first place.
    You planted a sample in a coffee cup in your office--did you not?
    You read their water meter so you can verify their gallons used, right? And asked for a copy of their water bill? What is their address--maybe I can look it up online and tell you how many gallons they used.

    Agree that having 40-50% Per Rye in the mix is good.
    OP - I hope to heck you did not guarantee the seed job. You can open up so many cans of worms if you say 100% satisfaction guarantee with an overseed job in existing turf. Way, way too many variables to offer any sort of guarantee, beyond the fact that your workmanship was culturally correct.

    You do realize that if you seed a 50/50 PRG/KBG mix you will end up with about 10 to 20% KBG in the lawn after everything is germinated. I know KBG is a pain to grow but worth it in the end.

    I think he will end up with a lot more KBG than that, because the PRG is going to weaken or die in the mid-summer heat, allowing the KBG to spread. For a Fall seeding, I would keep the PRG under 20% by weight, but not this late in spring. 50/50 by weight seems about right to me in Mid-May. It's a bit of a hail mary at this point anyway.
