How to Kill Fescue Grass


Fescue grass is a cold weather weed, growing in conditions that other plants deem unsuitable. Over a long winter, fescue grass can quickly take over an area, making spring weed cleaning a difficult task. Fescue grows a low, thick mat of grass, which chokes off the growth of other grasses or plants in a lawn. Fescue grass has deep roots, making it difficult to control. Add to that the fescue's prevalence to the fungal infection Acermonium coenophialium, and you have one big headache on your hands--and your lawn.

Step 1

Allow the fescue grass to grow to a height of 6 to 12 inches. Herbicides work best when the fescue is actively growing.

Step 2

Cut the fescue grass back using a mower so that the grass is to the ground, and allow it to regrow between 6 to 12 inches in height. This causes the fescue to use a great amount of energy and allows for the greatest coverage of herbicide to healthy fescue and new growth.

Step 3

Apply the herbicide using a spray wand directly onto the plants during March or April, or between September and October. Allow the fescue to die away, and pull the plant up with your hands, wearing safety gloves.
