I have a client that has K31 tall fescue, and they want a short grass instead. What would be a good choice, if any? I thought Bermuda would choke out anything over time, so would zoizia. What about centipede? What would be the best way to transform this lawn from K31 , to a nicer quality grass yard without digging it all up with a bobcat? THey are okay with overseeding over a few years to complete the job. Thanks for your help.
