How In the World Is This Tree Able to Produce 40 Different Kinds of Fruit??

Sam Van Aken is an art professor at Syracuse University in New York. He wasn’t always immersed of the world of art though- as a child, he grew up working on his family’s farm before pursuing his art career.

So, in 2008, when Van Aken learned that the orchard at the New York State Agricultural Experiment Station was about to be destroyed because of a lack of funding, he knew he had to put his farming past to use.

Many of the trees in the orchard were 150-200 years old, and grew ancient, antique native stone fruits varieties that have been mostly hybridized or modified by modern agricultural practices (commercially-grown fruits are selected for their look and size more than any other factors, including taste).

Aken knew he had to save these rare and ancient fruit varieties, so he bought the orchard and spent the next couple years trying to figure out how to graft parts of multiple trees onto one single tree.

He started by creating a timeline of when all the varieties of fruit (about 250 total) blossomed, so he could know precisely when to graft a new variety onto the main tree.

The grafting process basically involves making an incision in the main tree, and then inserting a shoot from the tree you want to add.

When the tree was young, he grafted directly onto its root structure. Once it reached two years old, Aken began using “chip grafting” to add new varieties of fruit to various branches.

Chip grafting involves cutting a small notch into a branch of the main tree. Then, a sliver of the tree to be added (including a bud) is inserted into the notch and taped in place. Over winter, the tree heals the incision, and in doing so incorporates the new fruit variety into that branch.

After five years, Aken completed his first “Tree of 40 Fruit”, as he calls them.

For most of the year, it looks pretty much like a normal tree, but in spring, it explodes with white, red and pink blossoms before bearing its various ancient varieties of plums, peaches, apricots, nectarines, cherries and almonds.

Since then Aken has planted 15 more “Trees of 40 Fruit” in museums, community centers and art galleries around the country. His next plan is to create an orchard of them in a city setting.
