Workers attach cabling to branches of Lincoln’s twisted catalpa tree to help protect them from breakage.
The beloved twisted tree in front of the Lincoln Public Library is estimated to be 110 to 120 years old — at least 50 years older than a typical Northern Catalpa. In a joint project, the Friends of the Lincoln Library (FOLL) and the Lincoln Garden Club (LGC) have funded a preservation project that could extend the life of the tree another 20 to 30 years.
With the expert advice of the Arnold Arboretum’s Sean Halloran and professional arborist Jonathan Bransfield, along with the approval of library trustees and town officials, the Lincoln Catalpa Committee planned an extensive preservation project. On December 11, a crew from Bransfield Tree Co. spent over four hours in two tall bucket trucks to perform the preservation work, which included cabling the upper limbs to help them withstand wind and snow, pruning unstable or dead wood from the canopy, and fertilizing and installing a protective mulch ring around the trunk. A videographer filmed the project and interviewed the crew, and Bransfield promised that a finished video will eventually be available to all.
A fresh layer of mulch covers the ground beneath the tree.
In a public presentation sponsored by the LGC, Halloran, head of woody plant propagation at the Arnold Arboretum, gave a talk on the twisted tree, the cloning project, twisting trees in general, and tree planting tips.
