    I have done some reading and come to the conclusion that if I want to drop fescue seeds into a bermuda or st augustine lawn here in the state of Texas, that I should do it in the fall when the temps are about 75 degrees or so.

    My question is... should I bag the entire yard when I mow it right before seeding to allow the seeds a better chance to make it to the soil?

    Any other things I should do to ensure proper growth? Anything I should do differently when seeding into a bermuda lawn vs seeding into a st augustine lawn?

    Thanks for all insights.

    Wouldn't you rather use an annual rye in the fall for green throughout the winter and then it will die out when temps are more favorable to SA and Bermuda.

    ok yea the rye sounds like a better plan.

    Anything I need to do to the bermuda/st augustine lawns right before I seed other than bag the last mow?

    Nope. You could sow annual rye onto asphalt and it would grow. I hate that stuff with a passion. It's okay as long as you don't mind a neon green lawn. Tractor Supply sells a grass mixture that is 60% tall fescues and 40% annual rye. I tried that on one customer's lawn and we were both very happy with the results.

    You got to strip it down almost to the dirt to get a perfect stand of rye. Don't even think about bagging just lower the machine a notch at a time and throw it towards the center into a big row. Then bag and maybe use a bagger to finish the final clean-up. Now....most cites are passing laws to prevent this overseeding because it uses a lot of water and they want water off in winter. And in our area you can't water but two days a week so rye don't come up very well unti around November.

    I am not understanding what you are saying here. Please explain in a noob friendly way. Thanks for your time.

    What type of St Augustine are you talking about?

    I'm not sure which kind of SA it is. Do you treat the various strains differently?

    We do here. I have never heard of over seeding SA but our winters are probably a lot more milder here than compared to TX. This probably allows us to have green lawns 365 depending on the verity of grass. Which would be pointless to over seed. I over seed Bermuda lawns with the rye.

    Given our winters have gotten a little cooler here in Tampa . Most of the SA yards went dormant brown. I tried a rye overseed on a few SA yards and it performed the same as on Bermuda. Green all winter and it died out about April. With the SA, Atrazine will kill of any rye that may survive.
