Propagation trays play vital role in producing healthy trees, study finds
Toronto, January 7, 2020 – Growers who are looking to give trees their best chance need to return to their roots, according to new findings from Vineland Research and Innovation Centre. Healthy trees depend on healthy roots and an ongoing study shows propagation trays can have a permanent impact on root development and growth.
The five-year study, led by Vineland’s Dr. Darby McGrath, analyzes the health and growth of trees propagated in five different trays, including the RootSmartTM system, and planted in the field in 2017. Findings from a recent dig of the two-year-old trees show root defects occurring in propagation trays were persistent and resulted in permanent defects including circling roots and root ball development.
