I got it from a friend about a year ago it was in bad shape but have been nursing it back. New to this Is it normal for old bulbs to shrivel. Concern it has sent up a new spike and I was very excited then the tips leaves tuned brown so I trimmed of the bad. Also cut back the watering and seems to be doing much better. It also is sitting higher in the pot and sending roots out should I divide it and repot thanks appreciate any help
