Bermuda grass (Cynodon dactylon (L.) Pers.) is used in many countries throughout the world as turf for lawns, parks and sports fields. It has a vigorous root system that extends deep into the ground via rhizomes. While Bermuda grass is a preferred lawn in many instances, its growth in flower beds, gardens or among another grass type in your lawn is likely not welcome. The key to removing Bermuda grass successfully is persistence. Unless you kill all the rhizomes, the grass will establish itself again.
Cut the sections of Bermuda grass out of the lawn with a sod cutter. Pull up the pieces of sod, removing as much of the root system as possible in the process. If the Bermuda grass is in a flower bed or garden, pull the grass out by hand, trying to capture as much of the root as possible.
Dig the soil, with a shovel, to a depth of 6 inches. Pull out any rhizomes you encounter in the soil.
Cover the bare soil with pieces of clear plastic and weigh the edges downs with rocks.
Keep the plastic in place for four to six weeks. This process is called solarization, and will kill any remaining rhizomes that emerge with the heat of the sun.
Apply a grass-selective herbicide directly onto the Bermuda grass. Spray the grass when it is less than 6 inches tall.
Water the Bermuda grass regularly. The herbicide works best when the grass is free of dust and growing vigorously.
Reapply the herbicide when any remaining Bermuda grass reaches 6 inches in height. Continue to irrigate the grass regularly.
Monitor the Bermuda grass. If any new growth emerges, spray it again with the herbicide at 6 inches in height. Once all the Bermuda grass is dead, pull the grass out by hand.
