Can confirm, once rented a house with bamboo in the backyard, it’s awful awful stuff and will spread very easily
The only way to keep it from moving further into yards or gardens is to pour concrete trenches it can’t grow thru. impossible to eradicate entirely and while it’s shooting new sprouts up from the ground after its first day or two of softness starts to get more wood like and are wicked sharp easily being able to pierce through skin/clothes/shoes and cause some nasty cuts.
No one should ever plant that stuff voluntarily!
