Thanks Maurice,
That's great informative feed back. I myself have noticed the root disturbance issue that you speak about. When I receive a triple or double fan I usually leave them combined. The recovery process for the newly transplanted plant is much faster with a strong root system. Small or single fans take much longer to re - establish themselves. Plants are sometimes smarter then gardeners, they know that they need a good support system (roots) to survive and prosper.

An afterthought about planting as soon as possible to establish health for coming winters reminded me of what my father once said, "You don't wait until the first snow storm to find out where to buy a shovel"
