This is a fun technique to ramify your wisteria. After the first flush of leaves has hardened off in early summer, and flowers are long gone, take each leaf and cut them down to two leaflets. This will result in a very thin looking bonsai, and you may wish to provide light shade for a week or two to avoid sun scald. Fertilize and water well. Unlike some bonsai, fertilizing wisteria in the spring does not seem to dampen flowering much. In several weeks your wisteria should flush again and it may well re-flower. The more times the wisteria flowers, the more ramification you’ll get. The ramification comes from the first several inches of the flower raceme, which sports new leaves and also flower buds for next year. Try this technique only on trees that seem vigorous and have sent out some runners, and if you’ve at least two more months to your growing season when you cut the leaves. And with any wisteria, grow them in full sun along with your pines. Cutting a leaf to one pair of leaflets. One pair of leaflets remain. Do this over the whole tree. In several weeks you’ll have a full tree (vine) again, and may have flowers as well. New leaves and buds on the base of the flower raceme.
