    It has been a warm winter; soils with good sun exposure may already have white pine weevil adults emerging from their overwintering sites.  In those sunny sites, look for adults flying on sunny days near the leaders of host trees (many more than white pine, find a list here:  Also look for telltale resin droplets in the same locations.

    What do you do when a freak snowstorm in the Northeast causes thousands of limbs to fall and millions of people to lose power? Hold the world’s largest tree care industry trade show in Hartford, Conn., of course!


    TCI EXPO wrapped up another successful event this year at the Connecticut Convention Center, despite an unprecedented early snow fall that wreaked havoc on the region. 1,937 resolute tree care professionals, more than 60 percent of expected attendees, fought their way their through power outages and downed tree limbs, even sleeping in cars and on floors, to enjoy three days of workshops, seminars and demonstrations focused on the tree care industry.


    The industry trade show, held November 3-5, powered through power outages, travel difficulties and reservation glitches to provide attendees from around the world with business, safety and arboriculture workshops and seminars; professional tree climbing demonstrations on a 30-foot tree inside the center; and the opportunity to compare equipment and evaluate products. The biggest names in tree care, 177 companies in all, exhibited at the show, sharing the latest tree care industry products and services.


    "Despite a storm that ravaged our host city and state for this year's TCI EXPO, customers showed up in good spirits and quantities,” says Tony Gann, Regional Vice President for Altec Industries, Inc. “This was one of the strongest shows I've seen in recent history for actual equipment purchases off the show floor."


    Many tree service companies that came to Connecticut for the show also performed double-duty, carrying out tree work for local residents hit hard by the storms. And on Saturday, November 5, TCI EXPO opened the show floor and gave free admission to all tree care crews who were working to restore essential services to the New England and Northern Atlantic Region. 


    “Despite a terrible storm that left hundreds of thousands of homes without power, the tree care industry came together for one of the best TCI EXPO’s to date,” says Bill Weber, Team Captain for Arborwear.  “No other industry bonds together like ours. Where else can you find exhibitors sharing their hotel rooms with last-minute attendees because hotels were without power, or have residents opening their homes to crews that have been working through the night?”


    In addition to the trade show and conference, TCI EXPO hosted a Student Career Days (SCD) event, which drew 230 college and high school tree care students from around the U.S. Many of the sponsoring tree companies organized a last-minute cleanup of Bushnell Park, site of the SCD competition, which was heavily damaged by the storm. Many students pitched in to help and spent hours working side-by-side with industry professionals.They also participated in friendly tree climbing competitions, took part in educational seminars, workshops and even a job and internship fair, which gave students enrolled in horticulture, forestry and related programs an inside look at the field they’re studying. Student Career Day was sponsored by Arborwell, Bartlett Tree Experts, Davey Tree Experts, International Society of Arboriculture, SavaTree, STIHL USA, The Care of Trees, Vermeer and Bandit Industries, Inc.


    TCI EXPO was sponsored in part by Crown partners Altec, Bandit Industries, Husqvarna, Morbark and Vermeer. Root and Seed partners included George Fern Exposition and Event Services, Liberty Financial Group, Inc., Buckingham, Fanno, HMI, Mauget, and Weaver Leather.

    Why limbs fall in your yard

    Travel around a neighborhood after a storm and you will see tree limbs, large and small, scattered about the ground. Why do some limbs fall in high winds or after ice storms while others merely bend? Should you worry about that large limb overhanging your driveway? 

    “One reason trees fail is weak branch unions,” says Tchukki Andersen, BCMA (board certified master arborist) and staff arborist with the Tree Care Industry Association. “Homeowners can educate themselves about tree limbs, but they should call a professional arborist if they are worried about an overhanging branch.”

    Trees may suffer from naturally formed imperfections that can lead to branch failure at the union of the branch and main stem. There are two types imperfections that create weak unions: a branch union with included bark and an epicormic branch. 

    Weak unions

    Branch unions can be characterized as strong or weak. Strong branch unions have upturned branch bark ridges at branch junctions. Annual rings of wood from the branch grow together with annual rings of wood from the stem, creating a sound, strong union all the way into the center of the tree.

    A weak branch union occurs when a branch and stem (or two or more co-dominant stems) grow so closely together that bark grows between them, inside the tree. The term for bark growing inside the tree is “included bark.” As more and more bark is included inside the tree, the weak union is formed that is more likely to fail.

    In storm damage surveys conducted by the University of Minnesota’s Forest Resources Department, 21 percent of all landscape trees that failed in windstorms failed at weak branch unions of co-dominant stems. Some species are notorious for having included bark: European mountain ash, green ash, hackberry, boxelder, willow, red maple, silver maple, Amur maple, cherry and littleleaf linden. 

    Epicormic branches

    Epicormic branches (also called water sprouts) are formed as a response to poor pruning practices, injury or environmental stress. Epicormic branches are new branches that replaced injured, pruned or declining branches. Commonly, epicormic branches form on the stems and branches of topped trees. When old, large epicormic branches are growing on decaying stems or branches, the epicormics are very likely to fail.

    Epicormic branches, by their very nature, form weak unions because they are shallowly attached instead of being attached all the way to the center of the stem. Epicormic branches grow very quickly so they become heavy very quickly. After a time they lose their connection to the main branch and may fall to the ground because the underlying wood cannot support their weight.

    “If a weak union is also cracked, cankered or decayed, the union is likely to fail, causing the branch to fall off the tree,” says Andersen. “Sometimes, ridges of bark and wood will form on one or both sides of a weakened branch union in order to stabilize the union. The branch is very likely to fail when a crack forms between the ridges.” 

    Find a professional

    A professional arborist can assess your trees to determine whether pruning or removal of limbs is warranted. Contact the Tree Care Industry Association (TCIA), a public and professional resource on trees and arboriculture since 1938. It has more than 2,000 member companies who recognize stringent safety and performance standards and who are required to carry liability insurance. TCIA has the nation’s only Accreditation program that helps consumers find tree care companies that have been inspected and accredited based on: adherence to industry standards for quality and safety; maintenance of trained, professional staff; and dedication to ethics and quality in business practices. An easy way to find a tree care service provider in your area is to use the “Locate Your Local TCIA Member Companies” program. You can use this service by calling 1-800-733-2622 or by doing a ZIP Code search on

    The Tree Care Industry Association (TCIA) today announced that it had been awarded a federal grant in the amount of $165,000 from the Occupational Safety and Health Administration (OSHA). 

    The grant was awarded through the Susan Harwood Training Grant Program, which provides funding for nonprofit organizations to conduct in-person, hands-on training and educational programs for employers and workers on the recognition, avoidance, and prevention of safety and health hazards in their workplaces.

    "With the help of this grant, we can work toward keeping workers safe," stated Mark Garvin, TCIA president. "It is an important component toward achieving our industry's goal of reducing injuries and fatalities with respect to electrical hazards in tree care work."

    TCIA will develop approximately 25 free workshops and train 750 employers and employees of tree care companies in safe ways to handle electrical hazards associated with trees. These select workshops, financed 100 percent through federal funds, will be offered to small businesses and limited-English, low-literacy, and hard-to-reach workers throughout 19 states.

    “No one should ever suffer injury or death for the sake of a paycheck,” said Secretary of Labor Hilda L. Solis in announcing the grant. “The grants awarded by the federal government today will provide tools for workers and employers in some of the most dangerous industries to identify and eliminate hazards. This education and training will help ensure that every worker returns home safely at the end of his or her shift.”

    Founded in 1938, TCIA is a public and professional resource on trees and arboriculture. It develops safety and educational programs, standards of tree care practices, and management information for tree care companies throughout the world. TCIA also has the nation’s only tree care company Accreditation program, a seal of approval that helps discerning consumers identify trustworthy companies.

    TCIA’s Electrical Hazards Awareness Program (EHAP), introduced in 1975, has helped train thousands of arborists – those involved in line clearance and those working on residential properties near energized lines.
