Come to the Aid of Arboretum Trees

In the morning hours of Saturday, October 23, 2004 - Bartlett Tree Experts arborist crews arrived in force at the U.S. National Arboretum to work on Arboretum trees. In this Day of Service, more than 60 of Bartlettís staff from home offices throughout the region completed various arboriculture tasks in the arboretumís collections. With them came a full complement of equipment and trucks. Without delay, staff broke into five work groups to work on trees in different locations throughout the Arboretum. Crews worked on cabling to protect an elm from storm damage, pruning dead wood from trees, root excavation of two trees to reveal root zone problems, planting maples in the Maple Collection, and fertilizing trees. Thousands of dollars of arborist services were donated in this single day of service. The dedication of support groups, like Bartlett Tree Experts, is instrumental in keeping the Arboretum grounds in good shape. Bartlett Tree Experts, headquartered in Stamford, CT, was founded in 1907. Bartlett has become a leading scientific tree and shrub care company and has offices throughout the U.S., Canada, Great Britain, and Ireland. Its chairman, Robert A. Bartlett, sits on the Board of Directors of the Friends of the National Arboretum.

Staff were briefed about the work they would be doing over breakfast at a local hotel, where many had stayed the night before. When they arrived at the Arboretum, they went directly to their work sites and began to work on the trees.

An arborist uses an air spade to blast the soil away from the root system of a failing 'October Glory' red maple in the R Street parking lot near the Administration Building. The excavation revealed a number of girdling roots that caused the tree to suffer. Some of the girdling roots were severed and compost was added to the soil to stimulate new growth.

Nearby, in the Court of Honor section of the Introduction Garden, arborists worked to prune trees overhanging some of the oldest specimens of Arboretum plant introductions.

The large lacebark pine in the Morrison Garden in the Azalea Collections has been declining for a few years. Cabling, using the newly developed Cobra system. Cobra cabling does not require drilling into branches and encourages the tree to form wood to brace its own branches.

Over time, an excess of mulch had built up. Under the thick organic layer, the ground was hard and dry. The excess mulch was removed and compost was added to stimulate root growth and improve the porosity of the underlying soil.

Pruning was completed in several large trees in the Maple Collection.
