Question: Bamboo is taking over my yard. What is the best way to contain this "weed"? (I now know I should have planted it in containers, but it's too late now.)

Answer: Bamboo spreads by underground stems. Since it was not planted in a container originally some sort of barrier needs to be installed. You will probably have to install metal edging at least one foot deep around the bamboo to keep it contained. It would be best if there was lawn on the other side of the edging, so you can mow down and kill any errant sprouts that come up.
