How do I fill these concrete planters to keep bamboo from escaping?

Tony Laurel

I've got two long concrete planters on my fence line.


Going to fill with Phyllostachys bambusoides (Madake/Japanese Timber Bamboo/Giant Timber Bamboo).


The planters are 30" deep, 18" wide, and 70 feet long in total. (two runs of 35')


Should I put sand at the bottom? Gravel? Some sort of water permeable layer?
