I was manicuring my flower beds last night and noticed tons of bloom stalks coming up on some tall-bearded iris clumps that I haven't divided in at least 5 years. Iris people always say to divide them every 2 or 3 years to maintain good bloom. But I think these have been in place 5+ years and they are going to bloom great! Other established clumps of irises are not producing bloom stalks yet... maybe they won't bloom? On the other hand, some of my daffodil & tulip clumps have been in place for 5+ years and they are barely blooming at all. Especially the daffodils... the clumps are a mountain of green, but maybe just a few blooms. Other clumps of daffodils are heavy with blooms. It's all very fascinating! Dennis in Cincinnati
