why does the bamboo shoot now in JANUARY?

17 years ago

I have just one bamboo. It is black bamboo. It is obviously a houseplant this time of year in zone 5.

I'm puzzled as to what occurs this time of year that causes it to produce the new green shoots. I mean-- the day length is short. The house temps stay fairly constant. It is in minimal if any direct light- so what is the trigger? Or do they all do this at this time of year world wide??

I have several bamboos under growlights on a timer with 16 hours of light and 8 hours of dark. From what I've seen, what seems to cause shooting is a mixture of the amount of stored energy in the bamboo and the temperature. An indoor bamboo seems to put up shoots any time of the year. At the moment I have Buddha Belly, MOSO, Heteroclada, Atrovaginata and a few others putting up shoots.

My neighbor has 35 ft high bamboo that is literally "shooting" penny sized pods in all directions. It sounds like someone shooting a pellet gun.The temperature in our area ( SF east bay ) has been in the mid to low 20's at night. Any ideas ? We've been here for twenty five years and this is the first time this has happened.

My Yellow groove is shooting indoors like crazy right now too! I must have had 10 shoots already and they seem to grow overnight, one minute I look and the culm is already 4 feet up, amazing! Esp for Ohio.
