I have recently bought some tubers that by the time I was able to plant them they had already grown 12-15" from the tuber. I planted them as specified but ~6" of the new growth was above the mulch. I have recently discovered that the new growth is black and obviously dead. Should of I cut this new growth off before planting or will the tuber send new shoots? Is there a way to save them?

Cut off the black growth and wait. Water sparingly and cross your fingers. if the roots were healthy they should survive.
