Tree Staking Research
We have been having an active discussion in our state about the benefits and drawbacks of staking trees. The most well known, and most cited, research is the Richard Harris research which shows staking landscape trees reduces root mass, caliper, and taper of young trees. It also Shows the negative impact of side pruning and heading of landscape trees on caliper and root mass. This research addresses the nursery growing culture, and many transfer this data to planting larger landscape stock.
Does anyone out there have additional research publications about the effects of staking trees, both in the nursery setting, and also in the final landscape setting? Thanks in advance for your assistance!

This comment came from the coordinators page: This link is from the University of Florida horticulture website. http://hort.ifas.ufl.edu/woody/staking.shtml. It appears to advocate a minimalist philosophy when doing staking. Florida Grades and Standards for Nursery Stock considers a nursery tree to be a cull if it cannot stand up by itself if the stake is removed at the time of planting. The Pennsylvania Horticultural Society is a proponent of outplanting larger bare root trees. Staking would be a must in that instance.

The April issue of ISA's Arborist News has an article on staking written by the landscape architect James Urban. He covers some of the research including from Richard Harris and Bonnie Appleton on impacts of staking and other tree stabilization methods. He presents cases for and against stabilizing trees. He also cites an article published in September 2011 in Arboriculture and Urban Forestry by Kendra Labrosse and her team from the University of Guelph that lists 20 references on the subject. The Labrosse paper looked at newly planted trees in Guelph, Ontario and found that trees on public land seemed to benefit more from staking than trees planted on private land. Hopefully you'll find some useful references there.
