The carrot top will develop fern-like leaves. Cut off top green leaves of a pineapple, with about one inch of the fruit portion attached. Put the cut-fruit end in a shallow pan of water, leaving green top well above water. Roots will develop after several weeks. Transplant to a pot of moist soil and cover with a clear plastic bag for three weeks.
