Collected Spring 2011, about 30 cm to the tip of the dead spire. The deadwood of this tree was sandblasted last year which helped preserve the lovely little jins. The pot is by Shibakatsu.
As I have recently come to own two satsuki azaleas, I realized I’d better figure out how they work. One step I took was buying and reading Satsuki Azaleas for Bonsai and Azalea Enthusiasts by Robert Z. Callaham. It is an interesting book with some good satsuki techniques, but the bulk of it is designed as a reference for identifying cultivars.
One interesting technique is known as futame-futaba-nokoshi, and it means pruning the tree such that each branch ends in two shoots, each with two leaves. All other growth is removed. This allows an opportunity to wire the young shoots and promotes budding in the interior of the tree. Essentially it is partial defoliation combined with branch thinning. This ‘Kaho’ azalea which I purchased last summer has been undergoing a major restoration project, and it seemed a good time to apply this technique. All of the secondary branching was cut off last year, so futame-futaba-nokoshi provides a good opportunity to carefully create the future secondary branches.
The cutting/wiring was done almost exactly one month ago, and the follow up pictures are from today. This tree will probably have another round of cutting this year, as well as flower bud removal. Some long and awkward branches still need to be removed/shortened.
This Carpinus caroliniana forest was made in the Spring of 2013 and this year it was defoliated for the first time. Owen Reich told me that American Hornbeam respond well to defoliation (maximum once per year) and indeed the results were positive. One issue I noticed is that as the second flush was coming in, some very vigorous leaves grew back at an accelerated pace and became very large. These were periodically removed to allow the smaller, less vigorous leaves to fill in at a more uniform pace.
The tree was defoliated May 31st, just after the new growth had hardened off. One month later, the second flush had filled in and hardened off.
