How to Kill Fescue Grasses in Bermuda

By Meg Butler ; Updated September 21, 2017

Few lawn problems are as cringe-worthy as patches of fescue grass in an otherwise green and luxurious Bermuda lawn. But fescue isn't just an eye sore. Since it grows most rapidly when the surrounding Bermuda is dormant, if left unchecked it may eventually take over the rest of your lawn. Plus, fescue may be a hay fever irritant. Luckily, this pesky grass is relatively easy to manage.

Mow your lawn low or hand cut the fescue so that it is as low to the ground as possible. Allow the fescue to grow to at least 3 inches in height.

Kill the fescue with a broad-spectrum herbicide according to the manufacturer's instructions. This should be done in the late afternoon on a day when there is no rain forecast for the next 48 hours and there is little-to-no wind.

Wait one week.

Clear the dead fescue, underground roots and 1 inch of topsoil from the treated area.

Mow the lawn.

Fill the bare spot with 1 inch of store-bought top soil and a starter fertilizer applied according to the manufacturer's instructions.

Sprinkle Bermuda grass seed. This is not an exact science. Ideally you want each seed of Bermuda to be roughly 2 cm from its neighbor.

Lightly press the seeds into the soil and then sprinkle them with just enough top soil to cover them.

Water the lawn well. Continue to water the re-seeded patches whenever they are dry. Resume you regular watering routine when the grass seedlings have reached the height of the surrounding grass.
