Help with sad looking bamboo!
I bought an 8ft tall giant japanese timber bamboo in Vancouver (mild weather) And brought it home to my much colder area. The first three nights dipped down to -12 celsius and then got nice and warm. The bamboo is currently planted in the ground with good drainage and an abundance of organic fertilizer and has been watered regularily. Day temperatures range from 10 to 20 celsius and nights don't get cooler than -5. However all but some of the leaves on the very top have turned yellow or dry crusty brown. I can see a new pointy shoot emerging out of the dirt that has ceased growing since I planted it. Is this normal spring time behavior for this species or do I need to interveen and try to save it? And if so what can I do? Thanks for your input!
