Hi Harold, one more late voice. We line out all siberian iris stock, except
tetraploids, every year early in spring. Each division has two to seven fans
depending on variety, health and orneriness. We send our spring customers
the five to seven fan pieces or plant them at the head of their block. The
two fan pieces go at the end of the block if there is room. In August and
September we send out the rest of the big pieces. In the meantime several
things happen. First, most of the central fans try to flower. This is not a
problem because the central fan will wither away in any case. We pinch out
the bloom stalk hoping to give the rest of the plant more energy. It's far
worse when some of them repeat bloom, and every fan but the small one on the
end puts up a stalk.
Up to the beginning of August the individual fans of a division hold
together, but a week later some cultivars start to fall apart. It happens
fast. During that time the rhizomes extend and new roots begin to grow.
After that we have to be careful about how we dig all varieties, because the
divisions can fall apart.
Over the last couple of years we have found that siberians transplant readily
in July with or without extra watering even in the hottest times. This is
not standard practice around here but it works with plants from one part of
the garden transplanted to another and with plants picked up at sales.
One last note. The two fan divisions planted at the end of the block
usually make great big divisions the next spring, while the bigger fans make
ordinary divisions. Lack of competition? Marty Schafer, Joe Pye Weed's
