Read this paragraph. Bamboo, which is actually a tall grass, is a beautiful plant that is easy to grow. It grows surprisingly fast. But bamboo also spreads very quickly. Bamboo can take over your whole yard, crowding out other plants and trees. If you like bamboo, we suggest that you invest in a plastic ring that you bury under the ground to contain the roots of the bamboo. The bamboo roots will not spread outside the ring. This way, you can enjoy a pretty patch of bamboo without it taking over your whole garden.
