The best lawn seed for your yard is dependent on where you live. There are three basic climate areas to consider when determining which grass would thrive in your area:
Northern regions where cool-season grasses thrive
Deep South/Gulf regions where warm-season grasses grow best
Transition zones between the Northern and Deep South/Gulf regions
