I'm new to this forum and I need some advice please!?
I'm wanting to plant some bamboo, either Gracilis Slender Weaver or Fargesia 'Fortune' bamboo in a raised garden bed.
I've attached pictures below- the garden bed is approx 12 meters long and 50cm high. The depth/width is also 50cm.
I'm wanting to plant it along the whole length, approx 10 plants?

Can anyone please tell me whether or not this is possible in a raised bed?
I was thinking of lining the bed with pond liner if i had too, but I'm worried that the clump may eventually wreck the brick work if the root bases get too big.
How big do they usually get with these varieties of bamboo?
Any advice would be greatly appreciated!
PS , in pictures, we are yet to fill the beds with dirt. We will be filling to the height of timber sleeper approx 45cm
Thank you in advance!!
