Thick-Bladed Grass Clumps: Kill or Keep?

Clumps of thick-bladed grass in yard. What is it? How to remove?

Options

1. Spot-kill with glyphosate: Shield surrounding grass. Re-sod or seed after dead (7–10 days).
2. Cut out as sod plugs: Remove clump + 2" soil. Replace with matching sod.

Warning

Bare soil = weed magnet. Whatever you do, replant immediately with desired grass.

ID First

Could be tall fescue in bluegrass, orchardgrass, or a desirable variety. Take a sample to Extension. You might want to keep it.

Don't create a bigger problem removing a mystery grass.
