Bonsai from the very beginning  193


        Lift the seedling and prune the roots



        1 Carefully lift a strong
        seedling from the flat. Most
        trees send out a long taproot,
        which is designed to burrow
        into the earth to give the tree
        stability; once this has been                                   In just six months
        achieved, fibrous lateral roots                                  the seedling has
        develop. For bonsai you only                                    developed a very
                                                                        long taproot
        want to encourage the fine,
        lateral roots—and by pruning
        back the taproot, even more
        of these finer roots will form.


        2 Spread out the roots on a
        clean, hard surface. Identify
        the taproot, and decide where
        you can safely cut it back. In
        very warm climates, such as
        Japan, black pine seedlings
        like these may have all their
        roots removed; they are then
        treated as fresh softwood
        cuttings, which leads to a
        completely fibrous root    1                                    2
        system. In cooler, more
        temperate climates in which
        black pines grow more slowly,
        it is better to be cautious and
        retain some of the roots.


        3 Cut through the taproot
        using a very sharp, clean
        knife. The cleaner the cut,
        the better the chance of
        root development.


        4 The root-pruned seedling
        is left with lateral roots
        only—and the makings of
        a fine fibrous root system.
