Bill, I can only refer to Spring foliage species. All my species and hybrids bloomed very well without replanting or moving in recent years, but I relate this maybe 99% to well time late summer rains. Rain here can be very uneven and we had very well timed rain this year so I had excellent bloom on all bulbs. Almost all here are in partial shade of deciduous trees and grow in clay. To divide or not may result in increased bloom or decreased bloom especially when connected to annual temperature and rain fall extremes. I find that bulbs after are reluctant to resume bloom after digging and dividing and may wait a year or two or rarely longer before resuming a normal bloom season, but I am subject to annual EXTREMES of temp and rain. In more moderate, temperate climates such as yours and Tony’s you may see very different respondents.
