Well, THAT'S certainly complete nonsense. Read article in the New Yorker at the gym this morning about how gingko trees drop all their leaves in an otherworldly synchronicity. During the course of one night, they all denude themselves in one huge fit of leave loss.
Really? As I walked my dog later in the day I came upon a row of gingko's. And what did I see. One had lost 80 percent of its leaves. Not all. Some. And up the block from it. Essentially all the leaves still happily attached to their parent tree. Synchronized vegetative nudity. I don't think so. Nice story. But one must file it under "fantasy". Nothing more.
