I've dug out several small black bamboo stalks (as part of thinning out the small stalks) with very few roots and planted each of them in 6" pots. Slowly, most of them started to die (curled up leaves, graying leaves).

I'm experimenting by cutting away part of the upper stalk and dipping the remaining tip in water (either by bending/securing the stalk into it's watering dish or attaching a water bottle on the upright tip with a water tight hole for the stalk, and filled with water).

It seems that some of the leaves have uncurled and stopped graying.

I'd like to know if, what I'm doing is actually helping or not.
