Well, I worked on the 'chid this morning.
Found nothing wrong with the roots or the cane itself!
I went over the entire cane looking for "something" that would've caused that but...zilch!
In any case, I removed that cane and while I was rearranging what was left I had a few mishaps
:
I broke a spike from one of the other canes and then broke the top of another cane right off!
On the sunny side of the story...I found a great keiki growing up from the bottom so I potted that and I spag & bagged the piece I broke off.
I'll post an update pic later.
