Re: Douglas Iris


Pacific coast irises HAVE to be moved when they're in active root growth,
which is easy to detect: there will be fat white roots forming at the
advance edge of a fan.  It's undoubtedly too late now in your area, but
the usual
windows are mid-autumn [around late Oct-early Nov in the PNW] and
early-mid spring [early April here].


In your area, the optimum time may be late fall, but the root growth is
the give-away.  If you wait tl fall, you might find that irrigation, after
it cools off, will stimulate root growth.
