I had a reader ask a question that I thought I would share with everyone.
The ideal time to start a fusion project is when the seedlings are still dormant. Since you will need to bare root the seedlings it is best to start just before the buds swell. After the seedlings leaf out assembly will be much more difficult. Have everything ready before you begin and try to complete the assembly of the tree as quickly as possible. Don’t trim the roots or branches. Don’t let the roots dry out. I assemble my trees in a large plastic tub filled with enough water to cover the roots.
