Glenn said that creating a plan for your trees is essential to obtaining the goal of being able to show one's tree. A plan is a timeline with objectives to be obtained along the way to reaching the goal of a show quality.
Abe Far wanted all to understand that we are a study group. We have guest instructors to push us ahead, but we are here to help each other advance our trees with the goal of one's tree being able to be displayed at our shows. Not all trees will be able to be shown. As we create more show quality shohin, we can get more space allotted if need be. Observing an instructor assisting another member is also very helpful because each tree is different. One can listen and observe the instructor go through the process of analyzing a tree to determine what needs to be done.
It is important to find a tree with aged trunks of good size which can be properly reduced to shohin size. Some of the better shohin come from older plants from the ground or larger 5, 7 and yes, 15 gallon nursery containers. One can find good shohin also in older 1 gallon nursery containers. Glenn had a very nice 'nana' cascade in training recently created from an old 1-gallon nursery container.
