After severing the rhizomes, you can install plastic root barriers to prevent future rhizomes from growing. If you don't want the bamboo at all, you can remove it manually or use special herbicides to kill it. To stop the spread of bamboo, cut the stalks to ground level to weaken them.
Then, dig around the stalks and sever the roots underground with a pointed shovel, which will prevent the bamboo from spreading underground. You can also confine bamboo to a specific area by digging a trench 28 inches deep, which is deeper than all bamboo roots.

The trench should be at least 2 feet 61 cm away from the bamboo shoot. Once the trench is dug, you should be able to locate the bamboo rhizomes growing horizontally under the ground. The rhizomes will look like the main stalk of bamboo growing out of the ground.
Sever and remove the rhizomes to control the direction of growth. Cut through all the rhizomes in two places with a pointed shovel and remove the separated sections. You can also try using a saw to cut thicker bamboo shoots and rhizomes. However, you'll have to dig out the soil all the way around the rhizome in order to get clear access to it with the saw. Place a plastic root barrier in the trench. You can purchase a plastic root barrier specifically made for bamboo online or at a home and gardening store.
Unroll the plastic root barrier and place it in the trench, so that it completely blocks off the rhizomes. Fill the trench back in with soil.
Filling in the space between the trench walls and the root barrier will hold the barrier in place and make it less noticeable. Cover the top of the barrier with soil and pat it down. Monitor the rhizomes and continue to cut them as they grow.
The rhizomes will continue growing out as the bamboo grows. Running bamboo rhizomes can grow 3—5 feet 0. Clumping bamboo rhizomes are less invasive than running bamboo and will only grow 1—3 feet 0. This type of bamboo should be cut annually.

Search online or at a home and gardening store for a weed killer with glyphosate as an active ingredient. This is because it is a non-selective herbicide. Cut the bamboo down to the ground. Use a manual or electric saw and cut down the bamboo near its base, so that it runs flush with the ground.
If you are cutting down a very tall bamboo plant, cut down the top of the plant first, then make another cut towards the base of the bamboo. Apply the herbicide to the bamboo stump. Wait till the bamboo shows new growth.
Applying the herbicide to the new growth will kill the bamboo stalk and the rhizomes under the ground. Sprinkle or spray the herbicide onto the top of the bamboo stump. Diluting the herbicide with water may weaken it and makes it ineffective.
Always read the instructions before using herbicides. There are specific moisture and temperature requirements to keep in mind when using these types of products. Do not apply this herbicide in or near bodies of water or you may kill surrounding wildlife. Repeat the process once a month until the bamboo dies.
It may take up to 4 applications of the herbicide to fully eradicate the bamboo. Continue to cut down new growth and apply the herbicide through the spring and summer. Method 3 of Cut the bamboo stalk to ground level. Use a pruner or saw to cut the bamboo down to ground level. Cutting down the main stalks of the bamboo will weaken it, but won't kill it completely. Dig around the bamboo and sever the rhizomes.
Dig a hole around the stalks of bamboo and sever the underground roots or rhizomes from the main stalk with a pointed shovel. The rhizomes will look like the main bamboo stalk, but will be growing underground. Severing and removing these rhizomes will prevent the bamboo from spreading underground.
Remove any existing rhizomes leading from the stalks. If you want to completely eradicate the bamboo, you'll have to follow the length of the rhizomes underground and remove them completely. This will stem new bamboo growth. Running bamboo will grow underground and can spread at a much quicker rate. Mow over emerging bamboo stalks.
Bamboo can be mowed occasionally without killing it, but constant mowing over a long period of time will weaken it enough to prevent future growth. Continue to mow over new growth until the bamboo stops growing. If bamboo is planted in large galvanized tubs, will that prevent spreading while allowing the bamboo to grow in height?
