⚠ Barrier that is under 60 mil thick has been shown to fail when containing bamboo.Made in the USA from Durable High Density Polyethylene (HDPE), available in 3 sizes:Cold climates use 24-inch depth by 60-mil thick.Warm climates use 30-inch depth by 80-mil thick.Tropical climates use 36-inch depth by 100-mil thick.
You can buy plastic barriers to put in the ground, obviously it's a lot of work though and most people don't figure this out until it's too late. Otherwise you have to occasionally chop into the ground along the edge of the bamboo with a spade to stop it from spreading.
You could even cut that in half and make it 50' because the runners really don't go deeper than 5".
