Steevens requires that the trees planted in Mankato’s public landscapes are Minnesota-grown. She explained that a red maple can grow here and can grow in Missouri, but the seedstock from Missouri would have a tough time surviving Minnesota’s climate. For that reason, the tree contractor has to search his network of Minnesota tree growers to locate the desired specimen.
In mid-March 2013, the Master Gardeners lost another long-time member, Gordon Herbst. Gordon had been a faithful member of the local group, but had also become a Certified Tree Care Advisor, a friend of the Minneopa State Park Prairie, and was a terrific resource when it came to answering tree questions. One of his favorite trees was the unusual Amur cork.
The Master Gardeners again asked Ashley to secure a specific memorial tree. This time, it wasn’t quite as simple. Koberoski searched for some time before locating the tree from Jim Schmidt at Creative Landscape, Inc. Amazingly, the tree was quietly growing at Schmidt’s place in nearby Eagle Lake. The Amur cork tree will mature into a medium-sized tree with a short trunk and broad crown. Its bark is deeply furrowed and it is tolerant to many sites.
Last week, on a beautiful mild sunny day, a small group of Master Gardeners gathered for the official planting of both new memorial trees, the Ohio Buckeye and the Amur Cork tree. Hardy in Minnesota, yet uncommon in the home landscape, these two trees can give Glenwood Gardens visitors a taste of beautiful choices available. Each tree is 10-13 years old, and by being installed with all of its roots present in an enormous ball of soil, will adjust to the move easily. Steevens installed rubber water bladders at the base of the trees to provide gentle watering for the first few weeks in their new home.
