I have recently built a new home and the builder sodded the yard with common bermuda. The only problem is that they did a bad job and didn't butt the sod pieces up together and there are lots of gaps and low spots in my yard. Not to mention that the sod was full of fireants and weeds. This lead me to call a grass company in Dallas and see what they could do to help. They told me that they would use a sod cutter and completely take up all of my sod and re-sod using 419 Bermuda or Zoysia. He assured me that it would look 100 times better than it does now. My question is that both neighbors have common Bermuda on both sides of my house. If I sod in 419 or Zoysia will their common Bermuda eventually spread over my yard?
