Greetings.

My wife and I had a new home built down in Kyle back in August of last
year. Our home was sodded on all 4 sides with Bermuda grass, which is
supposedly easy to care for.

It's driving me crazy.

Weeds, Yellow patches, very VERY uneven growth leading to mowing that
cuts some areas and doesn't even touch the tops of the grass in
others...

Is it possible to seed something else into this grass? Such as
Buffalo grass or some sort of other native grass? Help?
