Bermuda grass (Cynodon dactylon) is a species of perennial grass native to Africa generally grown in the warmer climates of the United States. Because Bermuda grass grows densely and can tolerate high traffic, it is often used in football fields, golf courses, public parks and private lawns. Weed control is practiced at various intervals during the growing season to maintain a healthy turf.
Mow the area. Before the Bermuda grass begins to grow in early spring, mow the turf between 1.5 to 2.5 inches long. Mowing removes dead organic material, such as leaves, from the turf and allows the grass to receive maximum sunlight for warm season growing.
Purchase pre-emergence herbicide granules needed for the turf from a local nursery, home improvement center or hardware store. The label on the bag will tell you how much to purchase for the size of area to be treated. Bermuda grass in many areas is considered a weed or pest, so be sure to read the label thoroughly before applying to the turf.
Apply pre-emergence herbicide to grass in early March with a broadcast spreader. Set the gauge on the spreader according to the manufacturer's instructions. Small hand-held spreaders can also be used, but are impractical to treat large areas of turf.
Pull any weeds that grow in the turf by hand. Some weeds will emerge in spite of the herbicide application. To keep these weeds from spreading, pull out each by the roots and remove from the area.
Purchase and apply post-emergence herbicides as necessary June through August. Summertime weeds like crabgrass, clover and broadleaf can be killed with targeted herbicide sprays. Many post-emergence herbicides are made to kill all plant life, so make sure and read the label thoroughly before applying.
Reapply pre-emergence herbicide to turf September through November. A second application of pre-emergence herbicide will help control the growth cold season perennial weeds.
