When I visited a banana plantation, they said they always kept the number of offshoot plants down to one so it wouldn't take too much from the mother plant and reduce the size of the crop.
so if it sprouts more and you want big bananas you might want to cut the extra offshoots off...the mother plant will die after it has produced the bananas. so keeping one keeps the number of plants stable too.
btw, there is a set number of leaves the banana plant will produce before it flowers, I don't remember the number (sorry) but I always thought that that was cool
hope that helps [img]http://www.**********.com/iB_html/non-cgi/emoticons/confused.gif[/img]
