  1. Hello Ross:

    The ridges on the roots are formed as the roots shrink. As they shorten, they pull the bulb deeper into the soil. One can see this in many daffodils and other bulbs that adjust their depth in the soil. Thanks for showing this to Daffnet.

  2. The bulb had a ring of feeder roots when in growth. The remaining two roots are the contractile roots than when successful widen to nearly 6mm in diameter. The further they contract the thicker they become. thanks
