I am new to all this bamboo and I'm getting lost in all the variety and technique.
I am wanting to do a landscaping job for a customer where we build a screen out of bamboo.

I've read on how to make a rizome barrier. Now, there are hurdles in this project.
The grade of the yard requires pretty tall bamboo. There is a 7ft fence there now and it's not blocking much. We may want in excess of 20-25ft.
Also, there are some huge old oaks right near where the screen is to be built!
So, do we want to try and make a full screen with a running bamboo? Or try and get some clumping sets to fill in little pockets near the trees?

And where can we get some transplants of whatever species we decide on? I had asked a local landscaping house but they said the only plants they sell will top out at 8ft tall.

Ok thanks in advance.
