Gigmac25, your post is intriguing, but unfortunately you are either a bad lier, or a poor assistant greens keeper. First off, your degree should be in agronomics, not ergonomics. I suppose this could be a typo or an incorrect autocomplete, but it raises a red flag immediately. Next you say you have had the seed tested for drought tolerance. This makes no sense as a grass' drought tolerance is something that can only be determined on mature grass, no the seed or the seedlings. I don't quite know what you mean that it's not a complete blend, you'll have to explain that one. Another issue I have with your story is that you chose to purchase this seed at a retail store when you work at a golf course! I'm sure you have access to the best seed available, and being an assistant greens keeper with a degree in agronomics, you should know that there are newer, much better cultivars available. One also wonders why you seeded twice. Is this some golf course secret? From your weather descriptions, it sounds like you seeded in late spring, or maybe early summer. Someone with an agronomics degree should know this is the worst time for seeding a cool season grass. Do you have an idea why your grass turned brown or do you just attribute that to the seed being bad? Well if you don't know it is probably due to fungal disease, lack of water, it being too hot for the seedlings, or a combination of all three. This can be avoided by seeding at the correct time. I can assure you that July in St. Louis is the worst time of the year for cool season grass, especially newly seeded tall fescue. Regarding fluoride levels in water, if you are talking about what the water company adds for tooth health, it has no effect. If it's well water, then a high level could be an issue, but most well water is tested for that and adjusted if it's too high. Regarding Rebels, while it is certainly not the best tall fescue you can get, it's also not the worst. I wouldn't use it as I know there are many better tall fescue cultivars available outside of the big box stores.
