4. Recommendations:
1. Use Bamboo that Clump ONLY. (it still spreads)
2. Keep Bamboo out of your garden.
3. See No. 2.
(I used Bamboo and after catching it invading 2 neighbours gardens (including going through a shed and removing it from their gardens, and
then digging it out of my own garden with a small digger 3 years ago,
I removed the "last" piece last month - I hope)
4. Don't do it.................it can go through cracks in concrete.......its practically unstoppable
