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.
