It seems like it's cold everywhere right now. That darn Polar Vortex swinging down and turning our mild, late winter into a my-brakes-on-my-truck-are-frozen-and-it-won't-move kind of cold, cold winter.
But is it the kind of cold that will set my bamboos back again? In other words, will they be "dead"?
Not dead like the castor beans...
...but there's certainly some leaf death that has occurred. Take a look at the curled leaves:
Those are almost certainly goners. The question though is how many of the leaves have died, and if the cold -- it was 3ºF (-16ºC) this morning, and 4ºF yesterday morning -- will have killed the leaf buds. That would be the worst scenario, as it means that the bamboo would have "top killed".
This foliage loss happened in the winter of 2013-2014, when it got down to -8ºF (-22ºC), so maybe this year won't be so bad.
I'll stay positive and focus on the good -- which is nearer to the ground on this plant.
There's still plenty of time for more cold weather, but I'm really hoping this was the worst of it. Unlikely, since January and February are typically much colder.
