Bamboozled by Bamboo

My Moso Bamboo seems to be a total loss.  The first broke in half last year in strong winds.  I duck taped it together with steel rods and it lived till this winter.   The other broke in half during stongs winds early in the spring.  Now it seems that I have nothing left of my investment.    As a last resort, I sprinkled the area around both with a high nitrogen grass fertilizer.  What could it hurt?   Now we wait.
