We've just installed the first trees in our gravel beds this year. We are continuing to expand the size and species used in this system for holding bare-root stock - extending the planting window of bare-root trees well in to autumn.
Gravel bed trees from our research nursery will be planted in Minneapolis, St. Paul, and on the University of Minnesota Campus. Long-term tracking and data collection will compare performance of these trees to those grown in other formats.
This photo shows typical root size and structure of an October Glory red maple.
Stay tuned for future posts showing root and crown development this season!
