golden goddess and alphonse karr rootball
hello,i need some help with a couple questions please.i have 2 bambusa multiplex golden goddess and 1 alphonse karr which are in the ground about 8 inches from a cement border thats about 7 or 8 inches tall and about 3 inches wide it separates our propety from neighbors with chainlink fence on top of that small cement border its about 30 feet long,my question is will the pressure of the rootball from either goddess or karr break that cement border??and my other question is that i put some cement garden edgers laying the flat way on top of the space between bamboos and that darn lil cement border so that no culms grow there ,will that help make rootball not as strong when it does reach border and will that hurt bamboo by not allowing culms to grow on that side of bamboo? sorry i know its alot to answer but i need the help and knowledge you guys have. thank you i got pictures but i have to figure out how to put on here,i can use help with that also if u would like to see pics.
