Question for you guys. I have Bermuda TIF-419 that was sodded 3 years ago. Looks good, but I have never been able to keep it from seeding out. I don't over or under water it, and I don't over or under fertilize it. The pH is spot on. I don't know what could be "stressing it" to provoke the seed heads. I'm tired of it putting it's energy into poking seed heads up instead of getting really dense. Any suggestions?
