Is it possible to transplant an outdoor black bamboo for indoor use?
Golden bamboo has been used as an indoor entryway plant at a couple places here. Black bamboo has been mentioned as working as an indoor plant on another web site. However, I wouldn’t expect digging one up now and bringing it in would result in a happy plant, probably works better to do this in summer, when the indoor and outdoor temperatures are more similar. As already indicated, the more humid and brighter environment of a cool greenhouse is much more likely to produce a good response than a warm, dark, arid living room. You might also get tired of all the litter bamboo produces trying to keep it as a house plant–outdoor plants brought inside also tend to be full of critters that come out of them when brought inside.
