Dutch elm disease (DED) is caused by an aggressive fungus (Ophiostoma novo-ulmi) that kills elm trees – regardless of their health. It is considered the most costly shade tree disease ever and will remain active in a community as long as there are susceptible trees. The fungus invades the water transporting vessels and produces toxins. To try and defend against the toxins, the tree produces gums and internal growths designed to block the advance of the fungus. The combination of the toxins and the defense mechanisms of the tree inhibits water flow to the crown, which causes wilting and eventual tree death.
How Does Dutch Elm Disease Spread?
Female elm bark beetles lay their eggs beneath the bark of dead and dying elm trees. If the elm is infected with Dutch elm disease the newly hatched beetles will emerge from the tree carrying the deadly fungus on their bodies. The beetles fly to healthy trees and feed on its 2-4 year old branches, thereby spreading the disease.
Besides beetle transmission, Dutch elm disease may also spread through grafted roots. When elms grow in proximity to each other, their roots can come into contact and graft together. This common root system provides the fungus with a pathway to spread through an entire stand of healthy elms very quickly.
What are the Symptoms of DED?
Dutch elm disease symptoms begin to develop 4 – 6 weeks after infection. The first noticeable symptom that results from the fungal occupation of the water-conducting vessels is wilting or “flagging” of one or more branches, usually starting at the branch tip. Leaves on the infected branches turn dull green to yellow, curl, and become dry and brittle. As the infection spreads the wood beneath the bark displays brown discoloration.
What Can I Do if My Tree is Already Infected?
Most infected elms cannot be saved. In rare cases, if the fungus has not moved into the root system, physically cutting out infected portions of the tree, with a process called tracing, can save the elm.
Sanitation is the most important tool for controlling Dutch elm disease on a community-wide basis. It involves the identification and removal of diseased elms. Such practices eliminate beetle breeding sites and reduce the number of disease-carrying beetles.
Root Grafts
Dutch elm disease can pass from infected trees into healthy trees through grafted roots. Macro-infusion of Arbotect does not prevent root graft infections. The only way to reliably prevent root graft transmission of the fungus is to physically sever the common root system.
How Can I Protect my Elm Tree?
The goal when protecting elms from the fungus is to evenly and completely distribute a fungicide chemical through the entire canopy of the tree.
To protect the tree from beetle-transmitted fungal infection, Arbotect fungicide must be evenly and completely distributed throughout the 2-4 year old branches.
The only way to get an even distribution is by a tree injection method called macro-infusion. Macro-infusion injects a large volume of solution into the root flares of the tree. This solution is then transported throughout the canopy by the tree, providing a protective fungicide barrier.
Arbortect fungicide does not protect elms from root graft infection. You need to physically sever the root system from neighboring trees by trenching at least 36″ down.
Below is an article Noel, our owner, recently wrote for TCI Magazine on employee retention through engagement
We all know how hard it is to find good help right now. While hiring great help is a challenge, it’s just the first part of building a great staff. Your company is probably a mix of experienced help, untrained new hires and everything in between. Maybe you are still trying to figure out which members of your team you want to retain and which ones you might need to “release to their destiny.” When do you start to invest in an employee’s long-term future in your company? More importantly, how are you going to retain your best people?
Compensation, security, growth, and management are just a few pieces of the employee-retention puzzle. Another element, and the one I want to focus on most for this article, is engagement. When employees are engaged, it means they are fully absorbed by and enthusiastic about their work. They are more likely to take positive actions to further the organization’s reputation and interests. Engaged employees feel they can make a difference and want to be a part of something larger than just their own position. Engaged employees are happier and more productive and are connected with each other.
Before I lay out some strategies to get your team more engaged, I must confess that I have failed in this endeavor numerous times in my own company. I have a small team of 13 people, and we have a very low turnover rate. Most of my employees have been with me for more than five years. But on several occasions, I have kept a productive employee around who I was not able to engage in our ethos of teamwork and constant improvement. Sure, they could climb a tree and operate machinery, but their unwillingness to buy in and become a part of our team culture led to other crew members not wanting to work with them and a general negative attitude within the ranks. Employee retention cannot be about keeping every employee; it has to be about keeping and engaging the best people and removing the ones who damage your company spirit.
Some of the basic tenets for engaging your employees are:
• Employees who understand their goals and how they relate to the company’s goals are more engaged.
• Employees who receive regular feedback and rewards are more engaged.
• Employees who are given opportunities to grow, learn and advance are more engaged.
I know, I just made it sound so easy. But we all know that none of these are as easy as they sound. I will share a few ways we have found to accomplish these goals in our company, with the disclaimer that what works in our culture may not work in yours. Because we are such a small company, we are able to employ many informal practices that may not be possible in larger companies. Engagement looks different in every company!
Having employees participate in tree-climbing competitions can be part of your investment in advancement. Climbers learn new tricks and techniques, while other crew members become emotionally engaged because of their exposure to a much larger view of our industry. TCIA staff file photo.
When it comes to understanding goals, there are countless ways to accomplish the task. I used to work at a company where each employee’s production was posted on a chart on the wall, where you could see your goals and compare them to others’. It worked there, but I chose a different route for our company because of my concerns that that system might cause more emphasis on competition within the company than teamwork and common goals.
We operate as an “open-book” company, so any employee can see where the money comes from and where it goes at any point in time. This gives all employees a better view of the big picture, and we welcome ideas from all team members on how we can be more efficient and profitable. As the company grows and becomes more profitable, all team members reap the benefits. Last year, every employee in our company received two raises because of their engaged efforts to raise the bar on quality and production.
For number two, feedback and rewards, we are always looking for better ways to let each team member know where he or she stands. To be honest, this practice is a very difficult one to manage in a company of any size. Part of the issue is that some team members really want to have the formal written employee review, while others prefer to just be pulled aside for a conversation about improvement – or a very public, kick-ass high five in front of everyone for their successes. We try to do a combination of both, although it is a struggle to make the time for formal reviews.
One other reward we use in our company is called “F-yeah Friday.” There are many weeks when we all get to the end of the day on Friday and everyone can just feel that we have had a really great week. We all gave 100%, nothing got broken, quality was top-notch and we worked safely. While there is no numeric formula that designates it as an “F-yeah Friday,” it is a feeling of team accomplishment that leads to the occasional unexpected meeting at the end of the day where everyone gets a few hundred dollars of cash from my checking account and a frosty beer while we talk about what our weekend plans are. While I eat the expense personally, it is worth it to provide them immediate feedback and reward for high performance as a team.
Of the three engagement tenets above, I most enjoy giving my crew opportunities to grow, learn and advance. One of our strongest cultural values is personal improvement. We encourage and reward credentialing. Because of the focus we put on certifications, we have two ISA Board Certified Master Arborists and seven more ISA Certified Arborists in a company of 13 people. While it takes time to get the ball rolling, I have found that once you get buy-in from a few, the interest in becoming certified becomes contagious. Another part of our investment in advancement is our company participation in the tree-climbing championship circuit. As a former competitor, I know how the competitions fueled my fire as I grew as an arborist. Now we have a company bus we take to several comps each year (except this year, as all were canceled!), and most of our team either compete or volunteer at the events. After every trip, the climbers on the crew can’t wait to use the new tricks and techniques they learned. The crew members also become emotionally engaged because of their exposure to a much larger view of our industry, instead of seeing only our little corner of the world.
I have many friends in the tree care business who have even better employee-retention rates than our company, and in every case, the reason is that their team is fully engaged and pushing together to be a success. Unfortunately, there is not room in this article to compile all the methods being implemented, but I am excited to have shared a few things that have worked well within our team. I encourage you to think of ways you might look past the usual tools of employee retention, like compensation and benefits. We will almost always find employees who are willing to stay if the money is right, but employees driven solely by income can poison your company’s culture. It is also unfortunate that some good employees will leave your company for personal reasons, even after you have trained them to proficiency. While it is disappointing to see a good employee leave after you have trained them, your company will suffer more if you don’t invest in them and they never go away.

All About Trees is caring for Springfield’s urban forest, one tree at a time.
Predicting the peak of fall color can be difficult. Missouri is blessed with a great variety of trees, shrubs, and vines. Their leaves turn at different times, so Missourians enjoy a fall color season that may last four to six weeks. Sassafras, sumac, and Virginia creeper are some of the earliest to change, beginning in mid-September. By late September, black gum, bittersweet, and dogwood are turning.
The peak of fall color in Missouri is usually around mid-October. This is when maples, ashes, oaks, and hickories are at the height of their fall display. Normally by late October, the colors are fading and the leaves beginning to drop from the trees. Fall color is usually finished by the middle of November.
The progression of color change starts earliest in north Missouri and moves southward across the state. Generally, the color change is predictable, but it can vary from year to year. Much depends on the weather.
Where’s the Best Place?
You can enjoy Missouri’s fall color almost anywhere.
For spectacular vistas, choose routes along rivers with views of forested bluffs, and along ridges with sweeping scenes of forested landscapes. In particular, the James River has spectacular fall sights.
On a smaller scale, drive on back roads, hike, or take a float trip under a colorful forest canopy on a clear, blue-sky day. Visit MDC Conservation Areas and Missouri State Parks.
Even treeless areas, such as prairies and roadsides, display beautiful shades of gold, purple, olive, and auburn with autumn wildflowers, shrubs, and curing, rustling grasses.
If you can’t get out of town, enjoy places with mature trees, such as older neighborhoods, parks, and even cemeteries.
Be on the lookout for emerald ash borers. The emerald ash borer (EAB) is a serious threat to ash trees in Missouri. This invasive pest will eventually kill unprotected ash trees. Many trees can be saved with the careful use of systemic insecticides. However, not all ash trees should be treated, and for many locations the start of treatments should be delayed. This guide will assist you in making decisions about protecting your trees from this invasive pest. Find more information at eab.missouri.edu.
In the Ozarks, we are proud of our trees. But a small insect is putting our beautiful ash trees at risk. The emerald ash borer is an invasive pest that will eventually kill unprotected ash trees. Treating your tree early can help save it.
Here are a few signs to know if emerald ash borers have affected your tree:
D-shaped exit holes about 1/8″ wide.
Winding, s-shaped tunnels just under the bark.
New sprouts on the branches and lower trunk.
Increased woodpecker activity on the tree.
Sparse leaves and/or branches dying in the upper part of the tree.

Dendrochronology is the dating and study of annual rings in trees.
General Sherman, a giant sequoia, is the largest tree (by volume) in the world, standing 275 feet (83.8m) tall with 52,000 cubic feet of wood (1,486.6m).
Leaves appear green because chlorophyll absorbs red and blue light energy, causing the green energy to bounce off the leaf’s surface.
In one day, one large tree can lift up to 100 gallons of water out of the ground and discharge it into the air. Learn more tree facts.
Methuselah, an estimated 4,765-year-old ancient Bristlecone Pine, is one of the oldest living trees in the world.
Tree shaded surfaces can be 20–45°F (11–25°C) cooler than surfaces in direct sun, helping homeowners reduce summer cooling costs. Find out more about trees and the environment.

The emerald ash borer (EAB) is a serious threat to ash trees in Missouri. This invasive pest will eventually kill unprotected ash trees. Many trees can be saved with the careful use of systemic insecticides. However, not all ash trees should be treated, and for many locations the start of treatments should be delayed.
1. What is emerald ash borer (EAB)?
EAB is an exotic, invasive, wood-boring beetle that infests and
kills ash trees in forests and urban areas.
2. What does EAB look like?
The adult beetle is dark metallic green with a bullet shaped body
that is one-half inch long and one-eighth inch wide. EAB larvae
(immature stage) are flat, creamy-white grubs with distinct bellshaped
body segments. Adult beetles are usually seen from midMay
through July on or near ash trees; larvae are found under the
bark of ash trees during the remaining months of the year.
3. Where did EAB come from?
The native range of EAB is eastern Russia, northern China
and Korea.
4. How does EAB spread?
EAB adults generally fly less than a half mile to mate and lay eggs
on ash trees, making the natural spread of this pest relatively
slow. Humans, however, can easily move EAB long distances in
a short period of time. EAB can hitchhike under the bark of ash
firewood, ash nursery stock, and ash logs and lumber, emerging
from these materials to start an infestation in a new area.
5. When was EAB first discovered in the USA? How did it get there?
EAB was discovered infesting and killing ash trees in the Detroit,
Michigan area in 2002, but researchers estimate it may have been
in that area for ten years prior to the initial detection. EAB was
likely introduced to the US in ash wood used for packing and crating
goods imported from China.
6. Where and when was EAB found in Missouri? How did it get here?
EAB was detected in Missouri in July of 2008. It was found near
Lake Wappapello at the US Army Corps of Engineers’ Greenville
Recreation Area in Wayne County. EAB was likely introduced to
Missouri by a camper bringing infested ash firewood from another
state.
7. Where is EAB now?
Visit eab.missouri.edu to view a current map of Missouri
counties.
8. What is being done about EAB in Missouri?
Several state and federal agencies are responding to the EAB
threat. Field surveys are done annually to look for new EAB
infestations. A statewide quarantine has been put in place
to help slow the spread of EAB. The quarantine prohibits
movement of hardwood firewood, ash trees, untreated ash
material (chips, logs, etc.), and EAB itself from Missouri.
Information about how to respond to EAB and the risks of
firewood movement is being publicized to communities,
industries and the general public. Cost-share funds are
provided to communities to help them prepare for EAB’s arrival.
Stingless wasps that parasitize and kill EAB eggs and larvae
are being released at several locations to establish them as
biological controls to help reduce EAB populations.
9. How can I help slow the spread of EAB?
Don’t move firewood! Inform your friends and neighbors of
the risks of moving firewood. If EAB hasn’t been found in your
county, keep an eye out for it on ash trees and report any
possible sightings to officials. Once EAB is known to be in
your county, consult the EAB Management Guide for Missouri
Homeowners for advice on managing this destructive insect on
your ash trees.
10. Does EAB have any natural enemies?
In North America, EAB is frequently eaten by woodpeckers.
There are also a few species of tiny, stingless wasps that
parasitize EAB eggs and larvae. These wasps have been
released in a few locations where EAB has been detected
to help reduce EAB populations. For more information on
EAB biological control, visit agriculture.mo.gov/plants/pests/
emeraldash.php.
11. Where can I get more information?
Visit eab.missouri.edu or call the EAB Hotline at 1-866-716-
9974 for more information related to EAB in Missouri. Other
websites with valuable information include emeraldashborer.info and dontmovefirewood.org.
Arborists specialize in the care of individual trees. They are knowledgeable about the needs of trees, and are trained and equipped to provide proper care. Hiring an arborist is a decision that should not be taken lightly. Proper tree care is an investment that can lead to substantial returns. Well cared-for trees are attractive and can add considerable value to your property. Poorly maintained trees can be a significant liability. Pruning or removing trees, especially large trees, can be dangerous work. Tree work should be done only by those trained and equipped to work safely in trees.
An arborist by definition is an individual who is trained in the art and science of planting, caring for, and maintaining individual trees. ISA arborist certification is a nongovernmental, voluntary process by which individuals can document their base of knowledge. Certified Arborists are individuals who have achieved a level of knowledge in the art and science of tree care through experience and by passing a comprehensive examination developed by some of the nation’s leading experts on tree care.
Pruning. An arborist can determine the type of pruning necessary to maintain or improve the health, appearance, and safety of trees.
Tree Removal. Although tree removal is a last resort, there are circumstances when it is necessary. An arborist can help decide whether a tree should be removed.
Emergency Tree Care. An arborist can assist in performing emergency tree care in a safe manner, while reducing further risk of damage to property.
Planting. Some arborists plant trees, and most can recommend species that are appropriate for a particular location.
Plant Health Care. Preventive maintenance helps keep trees in good health while reducing any insect, disease, or site problems.
Many other services. Consulting services, tree risk assessment, cabling and bracing trees, etc.
Have you ever imagined what the world would be like without trees? The benefits of trees extend beyond their beauty. Trees planted today will offer social, environmental, and economic benefits for years to come.
The social benefits of trees go beyond enjoying their beauty. Humans feel a calming effect from being near trees. The serenity we feel can significantly reduce stress and fatigue, and even decrease recovery time from surgery and illness.
Communal Benefits
With proper selection and maintenance, even trees can provide benefits to the community. Trees provide privacy, accentuate views, reduce noise and glare, and even enhance architecture. Natural elements and wildlife are brought to the urban environment which increases the quality of life for residents within the community. As well, fruit trees in public green spaces can have the added benefit of providing fresh fruit to the community.
Environmental Benefits
Trees alter the environment we live in by moderating climate, improving air quality, reducing stormwater runoff, and harboring wildlife.
Examples of the environmental benefits of trees:
Trees help moderate temperatures by creating a cooling effect which can counteract the heating effect of pavement and buildings in an urban environment.
Compact tree foliage can serve as a windbreak, as well as provide protection from rainfall.
Leaves filter the air we breathe by removing dust and other particulates and releasing oxygen.
Trees provide shelter for small animals, such as squirrels and birds.
Economic Benefits
The economic benefits of trees are both direct and indirect. Property values of landscaped homes are 5 to 20 percent higher than those of non-landscaped homes based on the species, size, condition, and location of the trees included in the landscape. Trees also provide shade which can lower cooling costs for your home and reduce heating costs in the winter by acting as a windbreak.
An arborist can help you determine the value of trees by providing an appraisal. Documentation on the value of trees in your landscape can assist with determining the property value, as well as help with insurance claims in the event of a loss.
Trees provide numerous benefits but in order to maximize a tree’s benefits routine maintenance is required. Though these benefits begin the moment a tree is planted, they are minimal compared to the benefits of a mature tree. The costs associated with removing a large tree and planting a young tree can outweigh the costs of regular tree maintenance practices such as tree inspection, pruning, and mulching.
