Depends on how involved you want to be, how many trees you want, what kind of tree you’re looking for, how much money you want to spend.
1. If you source the scion and roots, you can make the tree yourself (or hire a grafter) and be your own nurseryman. This is the least expensive method, but you can count on some attrition based on your knowledge and skills.
2. Depending on quantity and scion availability, bench grafts are typically ordered before Jan. of the year you intend to plant.
3. Sleeping eyes are ordered one year prior to the spring you intend to plant.
4. 2-year old feathered trees are 2+ years out.
Hope that helps
