Moving a clumping bamboo
I have a clump of Fargesia robusta that I planted about 2 years ago. I planted it too close to some other plants and it will need to be moved. It's still fairly small but steadily increasing in size and has just sent up a bunch of new culms. The clump is about 18 inches across, with the tallest culms now up to about 4 feet tall. How big a root system do they get, and how easy are they to transplant? Is it best to transplant now, or wait until fall?
