    Dear Journey North,

    My name is Alicia. I think the sap starts to flow in the spring in order to
    bring energy to the top of the tree so that the leaf production can begin.
    The trees are dormant in the winter and with the increase in the
    photoperiod, warm daily temperatures, and cold night temperatrues this
    stimulates the sap to move up the tree. The maple tree needs energy to
    produce new leaves for the coming summer and photosythesis to occur.

    Thank you,
    Alicia (Mrs. McGinley's class)
