Thanks for the suggestion John. I'll look into it.
As far as neighbors, that wont be a problem. Like I said, no one is behind me or across from me.
I'd want to plant the bamboo or other hedge only along the back for privacy and a wind break for my bananas. Since they started tearing the forest down the wind has really picked up.
Regardless of what I end up planting...
do you think the roots from the hedge will have a negative impact on banana growth?
Also here's an updated picture of the damage.
