A five-year tree establishment trial compared the RootSmart™ tray with four commonly used propagation trays. Black cherry and eastern cottonwood trees were propagated and planted into the field. Researchers dug up a row of trees each year to analyze the root systems for key traits that support healthy tree establishment.

 

The trial asked two questions. Do root defects occurring in propagation persist in the field? Can an open-wall tray design promote healthier root systems? 

​

The answers: Yes and yes. 

 

A report published by A.M.A. and Vineland summarizes the findings of the field trial.
