The Japanese beetle, Popillia japonica, has emerged to wreak havoc on your shade trees. Native to Japan as their name suggests, Japanese beetles are an invasive species that was first detected in the United States in 1916 (Rainbow Treecare, 2021). Due to its lack of predators in the US, it has been able to quickly spread through most states on the eastern side of the Mississippi River.

You can identify the Japanese beetle based on its iridescent and glossy appearance, with a green head and copper wing coverings. It has small tufts of white along the outside of its wing coverings.
The beetle feeds on over 400 species of shade trees and bushes (Rainbow Treecare, 2021). The beetle feeds by eating the leaf matter in between the leaf’s veins, leaving a skeleton-like appearance. If this happens to enough leaves, the beetles can easily kill your trees and shrubs, as the plant will no longer be able to photosynthesize. As well, the beetles send out a signal to other beetles in the area when they have found an acceptable plant host, sending more beetles into your yard.

So how do you get rid of Japanese beetles? One effective solution is a combination of a soil injection as well as a foliar spray to take care of any live beetles currently feeding on the leaves. It is important to begin foliar sprays at the beginning of adult feeding on plant matter, otherwise, the infestation can grow out of hand as more foliage is destroyed and more beetles come to feed. If you think you have a Japanese beetle infestation, please contact our office at 417-863-6214 and we can schedule a time for our Plant Healthcare technician to come to take a look at your trees and discuss your treatment options.
Once you reduce a tree down to a stump, it may seem like that is the end of the tree’s lifespan. However, this is not always the case. Sometimes, a tree can remain alive – with a little help from its neighbors.
Scientists recently found a kauri stump in New Zealand that is very much still alive. The stump, which is pictured above, was discovered while Sebastian Leuzinger was on a hike. Leuzinger noticed that this tree had live tissue, as opposed to the deadwood of a regular tree stump. Living stumps have been documented since 1833, but this is the first instance of this occurring (that we have found, at least) in the kauri tree (Ed Yong, The Atlantic).
This stump can only be kept alive one way: by exchanging nutrients and water with the trees surrounding it. The exchange of materials between trees is not a new phenomenon, trees have been found to use fungi to transfer nutrients from tree to tree. However, for this kauri stump to stay alive, it most definitely is connected to one or more trees via a root graft. In a root graft, the roots of two or more plants grow together and connect, allowing them to directly share resources without the help of fungi. Up to 150 species of trees are known to form root grafts (Kelly Mayes, Science).
Another thing that makes these living stumps remarkable is the anatomy of the tree. How it is set up, the tree pulls water up from its roots to its canopy. This action occurs as water evaporates off of the leaves, which then pulls up more water to take its place.
“The stump’s water flows at a fifth the speed of its neighbors’, but it does flow. The speed of that flow depends on what the surrounding trees are doing. If the neighbors’ sap flows faster, the stump’s sap flows slower. But if the neighbors reduce transpiration, whether at night or during heavy rain, the stump’s sap starts racing. This suggests that it isn’t just a passive part of its neighbors’ roots. Instead, it seemingly uses their downtime to gain more water” (Ed Yong, The Atlantic).
This is quite a remarkable find. While there is no evidence that all tree species can do this, and root grafting can only occur between two or more compatible species, this still has many implications for the tree service business. So if you have a stump in your yard that looks exceptionally alive or that you notice has living tissue rather than exclusively deadwood, you might have a living stump on your hands! A living stump does not pose any danger to your yard if it is left alone, and in fact, damage can occur to the living trees if root separation is attempted.

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!
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.
We’ve all had experiences with a customer who, no matter what you do, you just can’t make happy. Maybe you didn’t prune enough, maybe you pruned too much. The price was too high, the grass got torn up or you made them go inside because they kept entering the drop zone under the trees. Regardless of the complaint, they claim their expectations of how the job would be done were not met.
Noel cutting a tree limb, which is part of the tree removal process.
The very first step is to look within the company first. Did the salesperson do a good job of communicating the right expectations? Were the specifications for the job written clearly, with concise details of the work to be performed? Did the crew do exactly what was on the work order? Were they careless in protecting the customer’s property? Were they polite and willing to listen to the client’s complaints, and make every reasonable attempt to make them happy?
In many cases, we discover that we didn’t do a good job of building the right expectations, and then we must engage in conflict-resolution strategies. It also leads to us writing more verbose specifications, especially if we anticipate that the client may be difficult.
Sometimes, after all these assessments have been looked at honestly, we discover that we are working for a person who is simply unreasonable. I have had numerous clients through the years who make it a practice to complain after every single job. I have had customers (often lawyers!) who refuse to pay for the beautiful deadwooding job we did, because they actually just wanted the tree topped. I have been burned to the ground in online reviews over trees that weren’t ever discussed or included on the work order.
In our company, we make every reasonable effort to resolve these issues. Our reputation is our second-most valuable asset – our employees, our first. We do have a limit, however, to how much we will let someone take advantage of our good spirit.
We keep a list of exceptionally difficult clients so that when or if they call back, we simply tell them we are politely bowing out, and they will need to find a new provider. If a client is mean or cussing at my office staff, they immediately get fired as a customer. While we don’t like losing the income from this type of client, we have always found a boost in morale when we announce to the staff that they will never have to endure them again.
Continuing to work for such unreasonable clients is certainly setting your team up for failure.
Jumping Oak Gall FOREST HEALTH ALERT From the Missouri Department of Conservation
Tree species affected: White oak (Quercus alba) primarily, and some other white oak group species.
Concerns: Leaves on entire crowns of white oak trees turning brown in late spring. In some areas, whole hillsides appear brown.
Description: High populations of a very tiny, native, stingless wasp (Neuroterus sp.) cause pinhead-size galls (abnormal plant growths) to form on the undersides of leaves. Each round, button -like gall contains one wasp larva. Starting at the margins, brown, scorch-like areas appear on leaves where many galls are present. In more severe cases, leaves curl up, turn black, and drop early from trees. Effects of the damage become noticeable in late spring or early summer and remain visible until fall.
Most galls drop from leaves in early summer. Brown pockmarks remain where galls had been attached. Fallen galls are sometimes observed to “jump” due to vigorous movements of larvae within, much like moth larvae of “Mexican jumping beans.” This behavior allows galls to fall deeper into grass and leaf litter where they are sheltered throughout the coming winter.
Many species of gall wasps have two generations per year. It is assumed that the jumping oak gall wasp in Missouri has a similar life history with one generation lasting only a few weeks in early spring and rarely being noticed. The second generation extends from spring through the following winter and causes most of the leaf damage. Outbreaks typically last for one or two years and then fade away as natural controls reduce gall wasp numbers again.
Similar Leaf Issues: In years with cool wet springs, fungal diseases can be abundant on trees and may also cause leaf browning. Anthracnose is common on white oak foliage in those conditions. Botryosphaeria twig canker causes leaves on infected small branches to wilt and turn brown, which results in “flagging” in the canopy during the summer. Typically, twig bark shrivels and turns brown where the canker occurs, near the junction with healthy tissue.
Recommendations: Galls and fungi that affect oak leaves rarely have a significant impact on tree health. Nearly all trees will recover, even if all leaves are brown. Controls are not warranted. By the time the damage is observed, any opportunity to treat has already passed for that year, and populations are likely to decline naturally. However, severe leaf damage stresses trees, particularly if most leaves on a tree are killed which results in a second flush of leaves emerging in summer. The best tactic is using good tree care practices that reduce stress (mulching, watering during drought, avoiding wounds due to lawnmowers and trimmers).

Emerald ash borer (EAB), Agrilus planipennis Fairmaire, is an exotic beetle from Asia that was discovered (in North America) in the summer of 2002. The adult beetles nibble on ash foliage, causing little damage. However, the larvae feed on the inner bark of ash trees, disrupting the tree’s ability to transport water and nutrients, eventually killing the tree.
The emerald ash borer most likely arrived in the United States on solid wood packing material carried in cargo ships or airplanes arriving from Asia, and has most likely spread by hitchhiking on firewood transported among homes and recreation areas in at least 34 states.
In addition to Missouri, the emerald ash borer has been found in Alabama, Arkansas, Colorado, Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Nebraska, New Hampshire, New Jersey, New York, North Carolina, Ohio, Oklahoma, Pennsylvania, Rhode Island, South Carolina, South Dakota, Tennessee, Texas, Vermont, Virginia, West Virginia, Wisconsin, as well as, the provinces of Manitoba, Ontario and Quebec in Canada.
Since its discovery in the US, the emerald ash borer has:
Killed hundreds of millions of ash trees in at least 34 states.
Caused regulatory agencies to enforce quarantines and fines to prevent potentially infested ash trees, logs or firewood from moving out of areas where EAB occurs.
Cost municipalities, property owners, nursery operators and forest products industries millions of dollars.
Take action before removal is your only option! If you have an ash tree, you have the choice to protect or remove your tree(s). We recommend that residents consider protecting large, well-placed, healthy private ash trees as part of an EAB treatment program.
Considerations for Treatment:
Tree size greater than 10” in diameter.
The Tree is not competing with other trees or infrastructure.
The Ash tree shows no more than 30% of canopy decline if an infestation is suspected.
To better address situations such as these, All About Trees has created a Plant Health Care (PHC) & Integrated Pest Management Program.
Objectives of All About Trees Plant Health Care & Integrated Pest Management Program:
All About Trees is focused on appropriate care for trees and shrubs, using safe, effective, and well-timed visits and applications.
We only administer treatments as deemed necessary, and never try to just “make a sale” of pesticide applications.
All About Trees uses the safest methods for application, using as much systemic products as possible, and never doing tree sprays over 25’ high to limit drift possibility.
Our Plant Health Care Arborists will diagnose insect and disease problems, as well as soil, moisture, and fertility issues. We also recommend how and when a plant health issue warrants treatment.
Please give us a call if you’d like to be added to our calendar for a yearly maintenance check of your trees!
Tree Protection Zone (TPZ) – Avoiding Tree Damage During Construction
Tree Protection Zone (TPZ) is an area where construction activities are prohibited or restricted to prevent injury to preserved trees, especially during pre- construction and construction, and includes the Critical Root Zone and/or beyond.
How Trees Are Damaged During Construction
Physical Injury to Trunk and Crown. Construction equipment can injure the above-ground portion of a tree by breaking branches, tearing the bark, and wounding the trunk. These injuries are permanent and, if extensive, can be fatal. Root Cutting.
Digging, grading, and trenching associated with construction and underground utility installation can be quite damaging to roots. A tree’s root system can extend horizontally a distance 1 to 3 times greater than the height of a tree. It is important to cut as far away from a tree as possible to prevent damage that can compromise tree health and stability. Cutting under a tree’s crown can reduce tree vitality. Cutting roots close to the trunk can severely damage a tree and limit its ability to stay upright in storms. Soil Compaction.
An ideal soil for root growth and development contains about 50 percent pore space for water and air movement. Heavy construction equipment can compact soil and dramatically reduce pore space. Compaction inhibits root growth, limits water penetration, and decreases oxygen needed for root survival. Smothering Roots by Adding Soil.
The majority of fine water-and-mineral-absorbing roots are in the upper 6 to 12 inches (15 to 30 cm) of soil where oxygen and moisture levels tend to be best suited for growth. Even a few inches of soil piled over the root system to change the grade can smother fine roots and eventually lead to larger root death. Exposure to the Elements.
Trees in a forest grow as a community, protecting each other from the elements. The trees grow tall with long, straight trunks and high canopies. Removing neighboring trees during construction exposes the remaining trees to increased sunlight and wind which may lead to sunscald or breakage of limbs and stems.
Planning
Your arborist and builder should work together early in the planning phase of construction. Sometimes small changes in the placement or design of your house or driveway can make a great difference in whether a critical tree will survive. Alternative construction methods can be discussed, such as bridging over the roots as a substitute for a conventional walkway, if flexibility in placement is limited. If utilities cannot be re-routed away from trees, less damaging tunneling and trenching installation techniques exist.
Erecting Barriers
Treatment for construction damage is limited, so it is vital that trees be protected from injury. Set up sturdy fencing around each tree that is to remain, as far out from the tree trunk as possible to provide above- and below-ground protection. Place fence approximately one foot (0.3 m) from the trunk for each inch (2.5 cm) of trunk diameter.
Instruct construction personnel to keep fencing intact and the fenced area clear of building materials, waste, and excess soil. No digging, trenching, or other soil disturbance should be allowed in the fenced area.
Limiting Access
If possible, allow only one access route on and off the property. All contractors must be instructed where they are permitted to drive and park their vehicles. Often this same access drive can later serve as the route for utility wires, water lines, or the driveway.
Specify storage areas for equipment, soil, and construction materials. Limit areas for burning (if permitted), cement wash-out pits, and construction work zones. These areas should be located away from protected trees.

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.
The Tree Care Industry Association (TCIA) – Board of Directors
There are almost 200,000 people working in the tree care industry in the United States. Hi, this is Noel from All About Trees. Like most other trades, we have our own industry associations. The Tree Care Industry Association has almost 2,500 member companies, and it helps tree care companies meet current standards for safety and quality. I’m proud to announce that I’m the newest member of the board of directors for the association. I am by far the smallest company represented on the board, but I was chosen because of All About Trees reputation nationally, for our quality and company culture. It’s an honor to serve on this board and a chance for me to help other small companies, nationwide, with their dreams of growing their business and keeping their employees safe and happy.
