I am in the process of replacing a garden bed for my mother that has been overtaken by running bamboo. I have dug out all the dirt and want to use that to refill the bed. But I am worried about all the little pieces of bamboo roots. I am sieving the soil and removing as much of the roots as I can, but it is a very arduous task. If I just remove the larger pieces, will small pieces of running bamboo grow again once the soil is wet and yummy?
