Pond Boss Forums INTRO Questions & Observations Grass for new pond dam

I've read that in East Texas it is several weeks too early to plant cool weather grass seeds and several weeks too late for warm weather grass seeds. My newly built pond has a lot of bare dirt that needs something now to prevent erosion. If I plant both seeds now will the next rain cause germination of one or both? Will the warm weather grass seeds sit until next spring and germinate then?
