2. Bamboo can be an invasive threat to biodiversity.
Bamboo that spreads and escapes your yard can also cause ecological problems. Many spreading bamboo species are categorized as invasive exotic plants that crowd out native plants and threaten biodiversity.
The best ways to contain spreading bamboo can be expensive and complicated, and may not be worth pursuing for many homeowners. Moreover, they are not foolproof. Experts at the University of Georgia Cooperative Extension office recommend burying thick 60-mil polypropylene or fiberglass about three feet deep, and leaving another two inches of material above the soil to inhibit surface spreading. Morgan Judy of Clemson University Cooperative Extension suggests creating a solid barrier made of concrete, metal or pressure-treated wood at least 18 inches deep around the bamboo.
Any of these barriers should stop shallow bamboo rhizomes from spreading, but Judy still recommends closely monitoring the area for escaping shoots, particularly during the early summer peak growing season.
3. Getting rid of bamboo can take years.
Bamboo is a long-term relationship that should not be entered lightly. It may take years and vigorous effort to remove unwanted bamboo. The first step in removing bamboo is to remove all the root mass and rhizomes. This is easier said than done, and many homeowners with bamboo-loving neighbors complain they canít get rid of the spreading grass. No matter how much they dig, the shoots keep coming back.
Judy suggests frequent mowing can deplete and starve the bamboo, but it take at least two years of regular mowing to see any results.
