Wiregrass is the bane of many a gardener's existence, and getting rid of it entirely is time-consuming and quite difficult. The seeds, like the flowers, are tiny, with as many as one million seeds in one ounce, so you can imagine how hard it would be to get rid of them all! There are some things you can do, however.

If you are not comfortable with the idea of using strong chemicals, you can solarize the area for the summer. To do this, you must cover the ground with a thick black or plastic sheet, weighing it down with rocks or stones. Water the soil first before covering it so as to germinate the tiny seeds.

Keep the ground covered until September. By then, the Wiregrass should be dead, and you can install new plants.

Finally, if you don't mind a little manual labor, you can pull it out by hand. Keep in mind, however, that this is a time consuming process, and will only control the Wiregrass for a short while. It is the only way, however, to guarantee that nearby plants will not be harmed.

If these options do not appeal to you, you can kill the wiregrass. If you are willing to kill the plants in the entire area, you can use a chemical called Fusillade II. It will kill the Wiregrass, and also everything around it.

Best wishes with your project!
