Hello all,

I just purchased Red Clumping Bamboo (Fargesia nitida 'Jiuzhaigou') for container planting. My container is 20x20x20 inches and was wondering if I need to fill the entire container with soil or if I can use a filler up to a certain height? I'd like to keep the container as light as possible for ease of moving, but wasn't sure how much soil depth clumping bamboo needed.

Thank you for your advice!
