BonsaiCAM For May 1, 2004
Today we had a several trees on the bonsaiCAM, looking at some mid spring work. I also did a little work on a Japanese Black pine in order to demonstrate what would be done in Mid summer.
The first tree was a Ginkgo clump that needed pruned back. The goal here was increase the ramification (twigginess) of the tree. In order to do that, I cut back the shoots that had developed this spring into just a cluster of leaves at the base of the stem. This will promote backbudding and also result in shorter internodes on the resulting regrowth.
Ginkgo is an exception for me in that I don't pinch it. I let it grow out all it wants and then cut it back. So far this has worked pretty well.
A - the tree before any work
B - cutting back some of the long branches. It's important to bring the shoots into scale by making sure that the trunks lengths are proportional to their widths.
C - more shoot pruning
D - holding one of the twigs removed from the lower trunk
Note the difference in foliage lengths in photos A & C
C is the final photo (sorry to get C & D out of order!)
