Should I be worry

I am thinking about planting some clumping bamboo in the courtyard of my house and place them in a couple 4 feet x 4 feet spots on the ground - the surrounding area of these bamboo will be all concrete. Should I worry that roots will spread under the ground and go all over under foundation and cause damaged to foundation or became invasive to else area nearby Thank you

    Probably not, but it might help to know exactly what kind of clumping bamboo you are planting. In most cases, clumpers do not have aggressive rhizomatous growth. The clumps expand slowly with new culms appearing quite close to the mother plant, very much like any other tall clump of ornamental grass expands.

    It will take a few years to happen (5-8 or so) but eventually the clump will fill the opening. You can extend that time frame indefinitely by root pruning around the perimeter on a routine basis.

    But there is really no danger of the clump spreading to the extent where the foundation or neighboring planting areas are threatened. That's the great thing about clumpers - completely manageable!

    I don't know the exact name for it - i remembered that i bookmarked it somewhere on my computer but the link is no where to be found. Anyhow, are you saying the roots can live underneath concrete and slowly spread until it reach the outside concrete perimeter. That is scary.

    novie-
    You've read too many scare stories. If it is clumping bamboo it is clumping bamboo. It is not going to go anywhere. Just make sure that what you buy is a properly identified clumping bamboo species. More than once someone has been told that they were buying a clumping bamboo by a seller who was either ignorant or dishonest. If you go to a reliable nursery, especially one that specializes in bamboo, you should have no concerns.

    Often you can tell because the clumping kinds usually produce dense tufts with the culms packed closely together, much more so that when a runner like golden or black bamboo is growing as a clump.

    And most of the clumpers grown never send out a rootstock that comes up some distance from the main plant, without any culms between. That said, there are certain kinds that do in fact make dense tufts spaced out on creeping root-stocks. These are less likely to be encountered at non-specialist outlets, however.
