Invasive bamboo

Asked August 15, 2018, 3:16 PM EDT

I moved into my house about 11/2 years ago in the winter. last summer the bamboo started coming up everywhere from my neighbors house My neighbor claims she bought her house with no knowledge of the bamboo or nature of bamboo I paid to have it dug up and removed last year in her yard and mine. Of course the bamboo returned this spring and it is growing everywhere in other neighbors yards and under my house pulling away a concrete porch etc my neighbor doesn’t want to use any poisons etc I am at a loss. Does anyone have any advice or experience to share with me?

Bamboo is biologically a grass. Based on your description, the variety is a 'running' bamboo. Because this spreads through rhizomes, any rhizome left (from the removal last year) will sprout and continue to grow. I did a search and most sources say that this is a multi-year effort. and both recommend that you cut off tender shoots as soon as you see them (you can 'harvest' them to eat.) By not allowing the shoots to grow and leaf out, you are using up the stored energy of the rhizomes and they will eventually die.

If you can avoid watering the areas where the bamboo is shooting up that can reduce the vigor of the plant.
