Our research is conducted primarily at the 9 acre TRE nursery located on the St. Paul Campus. This facility includes container production areas, field growing area, and Missouri gravel beds. Work is focused on improved nursery practices for maximizing growth and improving long term tree health in the urban environment. The effects of various planting techniques on root health is one of our major research thrusts, as is research on the root systems of trees grown in Missouri gravel beds (aggregate hydroponic systems using gravel). Investigating trees for urban settings, primarily elms, is another emerging area. We also research claims made by TV personalities and garden gimmick salesmen.

My research program focuses on applied nursery and landscape issues with particular attention to the root health of trees and shrubs. To find out more about the TRE nursery and its research, extension and teaching activities please click http://www.tre.umn.edu

My extension program is focused primarily on the nursery and landscape industry though I also work with consumer and urban horticulture. I work closely with the MNLA (Minnesota Nursery and Landscape Association) who provide support and advertise the programs that I organize.
