Finally had a chance today to go outside while it was still light out. Lifted the frost blanket I had on the Mexican Weeping Bamboo and the Bambusa Oldhamii "Giant Clumping Timber Bamboo," and no damage, woo hooo! All my other bamboo in the ground looks unfazed by the weather. Hard freeze, what hard freeze? Did pretty good. I'm a happy man! Cheers!
