How To Keep Neighbors Bermuda Grass From My Fescue?

Q: How do I keep bermuda grass from my neighbor’s yard from spreading into my fecue? 

A: If your neighbor has bermuda grass in their lawn, it is going to come into your lawn pretty quickly, particularly if they have “common” bermuda, not sodded varieties. Common Bermuda is an aggressive spreader and reseeder. All you can do is make a trip around the perimeter of your lawn every month and spray a narrow strip with glyphosate (Roundup, etc) to kill any of the neighbor’s invading grass.
