Tip for digging up bamboo
A family friend has a stand of some sort of hardy bamboo (I have no idea what it is). Two years ago I spent over a half hour sweating my socks off trying to dig up a single culm to transplant. I only had a spade and that was it.
The next year, I was digging up and dividing some other mystery bamboo I have (thougth it was p nigra, but it's not). I had a hand pruner with me. I saved tons of time by using it to cut the runner below ground after I unearthed some of it with the shovel. Geez, it was so easy! I felt pretty stupid for struggling with them the previous year, let me tell you! Just wanted to pass this along to anyone who's thinking of dividing and expanding their bamboo this year.
